How Assessli is Building the World’s First Human-Centric LBM

Assessli is an AI startup building Large Behavioural Models to personalize human decision-making using genomics, psychology, and real-time data.

Assessli is a Kolkata-based AI startup pioneering the world’s only Large Behavioural Model (LBM) - an AI framework that understands humans through biology, psychology, and behaviour. By integrating genomics, neuropsychology, and real-time signals, Assessli builds personalised AI companions that adapt to individual moods, health, and decisions - transforming artificial intelligence from generic responses to truly human-aware intelligence.

How The Journey Started

The Assessli journey began on the bustling streets of Bangalore in 2020. Suraj Biswas was working as a Zomato delivery boy then every day. His first delivery earned him just 34 rupees, but dreams burned bright. He was studying genomics at a private college during that same time. Every rupee from his delivery work went toward funding his education completely. During long delivery shifts, he thought about creating something revolutionary and impactful. He wanted to build AI that truly understands each person deeply. The idea came from his research in epigenomics and behavioral science together. He saw how genomic data, psychology, and biosignals could transform AI fundamentally.

He conducted 80,000 surveys during the COVID pandemic to understand real problems. He talked to students, teachers, and parents about personalized learning needs. He researched how people make decisions based on mood and energy. He filed his first patent applications while still a college student. The journey officially started when he incorporated Assessli in Kolkata in 2020. Kolkata became the headquarters because of the city's emerging startup ecosystem. Indian Statistical Institute in Kolkata provided the first major breakthrough and support. The city's talent pool and research institutions made it the perfect base.

The Boy From West Bengal

Suraj Biswas grew up in a small town in West Bengal. His family struggled to make ends meet every single month without fail. His father worked as a house painter to support the entire family. Money was tight and luxuries were completely out of reach for them. Suraj did not own a smartphone until after completing tenth grade successfully. He visited crowded cybercafes to access the internet sparingly back then only. Every rupee mattered when pursuing education and basic learning needs in school. But one biology textbook chapter changed his entire life forever and completely. That chapter talked about genes and what makes humans unique from biology. A simple question formed in his young curious mind immediately after reading. What makes every single human so different from each other biologically?

A Loss That Changed Everything

Tragedy struck the Biswas family hard in the year 2019 unexpectedly. Suraj lost his beloved cousin brother to cystic fibrosis disease tragically. Cystic fibrosis is a rare genetic condition with no cure available. The loss hit Suraj deeply and changed his entire perspective on life. He wanted to understand diseases at the genetic root level completely. He dreamed of preventing such losses through better technology and genomic research. Around the same time, Suraj volunteered with underprivileged children in poor communities. He distributed food and clothes to families struggling with basic daily needs. One day a child asked him a heartbreaking question very simply indeed. When will I finally get to go to school regularly everyday?

That question exposed the inequality in education access across India very clearly. Suraj realized technology could level the playing field for everyone equally. He saw how personalized learning could help students like him succeed better. He understood that one size fits all approaches fail most people. He wanted to build something that adapts to each individual person uniquely.

The Entrepreneur Hustle Begins

After high school, Suraj faced a harsh financial reality very quickly indeed. He could not afford expensive medical college fees at all unfortunately. His family had already spent everything on coaching center fees for exams. Suraj moved to Bengaluru to find work and fund his genomics studies. He started working as a delivery boy for Zomato food delivery immediately. His very first delivery earned him just 34 rupees only that day. He worked over twelve hours daily riding through traffic and intense heat. He earned around 40,000 rupees per month on average very consistently there. Every rupee went toward enrolling in a private genomics college for education.

The hustle was real and intense for a young entrepreneur like him. He attended college during the day and delivered food at night. He read research papers on his phone between delivery orders constantly. He drafted business plans on notebooks during his breaks from work. He had no fancy office, no co-founder, and no investor backing. He had only his vision, determination, and relentless work ethic daily. This period taught him the true meaning of entrepreneurship and hard work. It taught him that success requires sacrifice and unwavering commitment to goals.

Major Challenges Faced

Building Assessli from scratch presented enormous challenges at every step forward. The first major challenge was gaining acceptance from the industry and investors. Deep tech startups are hard to understand for most traditional investors. Behavioral AI was a concept too advanced for many people then. Suraj approached over 100 investors with his revolutionary idea confidently during 2020. Investor after investor rejected his pitch as too risky and impractical entirely. Many said the idea was too complex to build practically at all. Others felt it was too early for the market currently right now.

The second major challenge was credibility as a young founder from nowhere. He had no IIT degree, no Silicon Valley experience, no network. He was just a college student with a big dream and patent. Getting people to take him seriously was incredibly difficult every single day. Building a team was challenging because he could not pay salaries initially. Convincing talented people to join a risky startup seemed almost impossible.

The third challenge was technical complexity of building behavioral AI models. Creating algorithms that understand genomics, psychology, and biosignals together was unprecedented globally. No existing frameworks or architectures could handle this unique data combination properly. The team had to invent new approaches and train models differently. Accessing medical and genomic data required strict privacy and consent protocols. Building trust with users to share sensitive health data was critical.

The fourth challenge was competing with AI giants like OpenAI globally. People kept asking how a small Kolkata startup could compete internationally. Resources were limited but the vision remained crystal clear and strong. The team worked 16 hour days to build technology faster than expected. Every rejection became motivation to prove doubters wrong through solid work.

The Research Years Begin

Suraj enrolled in a genomics degree program during the COVID pandemic period. He studied human genes and biological patterns day and night without stopping. At night he read research papers on artificial intelligence models extensively. He drafted frameworks combining behavioral science with biology and genomics data together. The idea of Large Behavioural Models started taking shape very slowly. He realized existing AI missed the most important data points completely today. Language models like ChatGPT train only on text and images exclusively only. They do not understand individual health, mood, or energy levels at all. They cannot predict needs based on personal biological rhythms every single day.

Suraj wanted to change this major limitation through innovative technology and approach. He wanted AI that reads biosignals from wearables like smartwatches and trackers. He wanted AI that understands genomic data and medical history completely. He wanted AI that adapts to learning styles and cognitive patterns uniquely. He wanted to create a digital twin for every single person.

The Breakthrough At ISI Kolkata

In 2023, Suraj applied to Indian Statistical Institute in Kolkata for support. ISI is one of India's most prestigious research institutions in the country. He presented his Large Behavioural Model concept to expert reviewers there carefully. Initially, his application got rejected by the review committee at ISI Kolkata. Suraj did not give up after that first rejection at all whatsoever. He re evaluated what went wrong in his presentation very carefully indeed. Within one month he reapplied with improved research documentation and technical details. This time ISI Kolkata awarded him a research grant of money immediately.

The grant amount was 10 lakh rupees for development and research work. That recognition opened doors that were previously closed to him before completely. The ISI grant gave Suraj credibility in the startup ecosystem across India. This was the first major turning point in the Assessli growth story. Mentors started reaching out to help guide his journey forward into success. Within two months, investors from Kolkata showed genuine interest in his project. Suraj raised 3 crore rupees in a pre seed funding round quickly. The funding came through in just seven days incredibly fast for startups.

This moment proved that Kolkata could produce world class deep tech startups. The city's research institutions like ISI provided the perfect launchpad for innovation. The collaborative ecosystem in Kolkata helped Assessli grow rapidly from there.

A Personal Loss and Unshakable Resolve

In late 2023, life tested Suraj in the most painful way possible. His father was diagnosed with stage 4 lung cancer in November that year. Despite the emotional and financial strain, Suraj had to continue building Assessli and pursuing his research commitments. Around the same time, he received the grant approval from ISI Kolkata - a major breakthrough that required him to travel from Bengaluru to Kolkata for official documentation. Just two days after completing the formalities, tragedy struck - his father passed away in January 2024. Suraj couldn’t see or speak to his father one last time. That moment became one of the hardest sacrifices of his entrepreneurial journey.

He often reflects that entrepreneurship demands more than ideas and effort - it demands sacrifices and moments of deep self-doubt. Yet, he believes his father would be proud, knowing that every hardship and every loss had meaning. The pain transformed into motivation, reminding Suraj that every struggle, every sacrifice, and every sleepless night has been worth it.

Building Assessli From Kolkata

Assessli established its headquarters in Kolkata at ERGO Tower in Salt Lake. The decision to build from Kolkata was deliberate and strategic entirely. Kolkata offered access to premier research institutions like ISI and others. The city had a strong talent pool of engineers and researchers. Operating costs were lower compared to Bangalore or Mumbai significantly at all. The supportive government policies for startups made it easier to operate.

The team worked day and night to turn research into reality. They started building the first version of Assessli's AI engine from scratch. They focused on creating algorithms that understand human metadata completely and deeply. They built systems that could process genomic data, biosignals, and psychology patterns. They designed interfaces that connect with wearables like Apple Watch and trackers. They created a platform that builds a digital twin for users. The digital twin learns from every interaction and data point collected daily. It understands mood, energy, stress, focus, and cognitive patterns in real time.

Key Growth Factors And Strategies

Several key factors contributed to Assessli's rapid growth trajectory from Kolkata headquarters. First, the focus on solving real problems rather than chasing trends. The team built technology that students, educators, and healthcare providers genuinely needed. Second, the patent protection provided a strong competitive moat against competitors. Multiple patents secured Assessli's unique approach to behavioral AI models and technology. Third, strategic partnerships with education giants like Narayana Group created revenue streams. These partnerships validated the technology and brought 200,000 users onto platform.

Fourth, participation in prestigious programs like nasscom AI Foundry and Wadhwani Foundation. These programs provided mentorship, network access, and credibility in the ecosystem. Fifth, international expansion starting with the Moscow Startup Summit representation in Russia. Being selected as one of only 7 Indian startups opened global doors. Sixth, maintaining Kolkata as headquarters showed commitment to building from tier cities. This inspired other entrepreneurs and attracted government support for the startup.

The growth strategy focused on B2B partnerships initially to validate technology. Schools, coaching institutes, and universities became early adopters of the platform. This provided valuable data to train the behavioral AI models better. Revenue from B2B clients funded further research and development work continuously. The team reinvested profits into improving technology rather than marketing expenses.

What Makes Assessli Truly Different

Assessli does not build chatbots or simple productivity tools like others today. It creates Large Behavioural Models trained on human metadata entirely and exclusively. The LBM combines genomic data with medical history and psychology patterns together. It reads biosignals from wearables like Apple Watch and Google Fit constantly. It tracks heart rate, stress levels, and energy patterns throughout the day. It understands learning behavior and cognitive preferences through daily interactions and engagement. All this data builds a digital twin for each user individually. The digital twin evolves and learns more every single day continuously.

When a user asks a question, Assessli checks their current biological state. If tired, it keeps answers short and simple to understand easily. If anxious, it slows down the pace of information delivery for comfort. If someone avoids math, it removes heavy equations from all explanations. If someone learns through videos, it suggests clips instead of text. This is hyper personalization that no other AI company offers today.

Real World Impact Today

Assessli now serves over two lakh users across India very actively. Leading education groups use Assessli for personalized student learning paths and support. Major coaching institutes have integrated the platform into their teaching systems completely. Narayana Group, a massive education chain, is a key client now. The AI helps students prepare for competitive exams more effectively than before. Teachers get insights into each student's learning patterns and struggles in detail. Healthcare providers are exploring Assessli for personalized medicine delivery solutions very soon. Mental health applications show tremendous promise for adaptive emotional support for people.

The platform understands when students are losing focus during study sessions daily. It suggests breaks or changes learning methods based on energy curves. It predicts when someone might face mental health challenges based on data. It provides personalized recommendations that actually work for each individual person uniquely. This is the power of Large Behavioural Models in real world applications.

Recognition On The Global Stage

Assessli gained recognition as a top AI startup globally very recently. F6S ranked it among the top 2 AI startups worldwide impressively. It competed against over 2 million startups from around the entire world. Suraj represented India at the Moscow Startup Summit in 2025 proudly. Assessli was one of only 7 Indian startups invited there for showcase. At the summit, Suraj met the Russian Deputy Prime Minister in person. He also spoke with the President of Sberbank extensively there about AI.

The story of that meeting became legendary in startup circles across India. Suraj was pitching at the Assessli booth when a group approached him. One person wearing glasses asked him to explain the behavioral AI model. Suraj gave his usual passionate pitch about hyper personalized intelligence and technology. The person listened carefully, appreciated the work, and spoke in Russian. Only later did Suraj realize he had pitched to the Deputy PM. They praised Assessli for building something truly ahead of its time. The meeting opened doors to international partnerships and collaborations immediately after that.

People started recognizing Assessli as a pioneer in behavioral AI technology worldwide. Investors from different countries started showing interest in funding the company. The global recognition validated Suraj's vision and years of hard work completely. It proved that deep tech from Kolkata can compete globally successfully. It showed that Indian startups can lead in cutting edge AI research.

Securing Major Funding For Growth

Assessli recently raised 44.4 crore rupees in a major funding round from Foxhog Ventures. That amounts to approximately 5 million US dollars for expansion and growth. The funding validates the market need for personalized AI solutions globally today. Multiple patents now protect Assessli's unique LBM architecture and approach from competitors. The intellectual property gives Assessli a strong competitive advantage globally in markets. Investors believe in Suraj's vision of human centric artificial intelligence deeply.

The funding will help Assessli expand to new countries and markets. It will help build better technology and improve the AI models. It will help hire more talented people to join the team. It will help conduct more research into behavioral intelligence and genomics. The company is on track to achieve significant valuation milestones ahead. With continued growth and international expansion, Assessli aims for unicorn status soon.

The Physical AI Companion Vision

Assessli plans to launch physical AI companions within six months from now. These devices will work independently without requiring a phone nearby at all. They will hear, see, and sense the environment around users in detail. They will understand context better than any screen based app can today. The physical companion will guide users through daily decisions naturally and seamlessly. It will monitor health and suggest actions based on real biosignals collected. Students can use it in classrooms to transcribe notes and explanations.

Workers can rely on it for productivity coaching throughout long workdays effectively. The physical AI companion represents the future of personal AI technology. It will make AI more accessible to people without smartphones or internet. It will bring the power of behavioral AI to everyone everywhere.

Growth Strategy For Coming Years

Assessli has ambitious yet achievable plans for rapid expansion ahead globally. In 2025, the company will launch its consumer facing application widely. The physical AI companions will ship to early customers very soon. Expansion will cover India, United Kingdom, and United States markets first. The company recently incorporated in both UK and US territories officially.

By 2026 and 2027, Assessli targets 10 million active users worldwide. The team will launch open source LBM APIs for developers to use. Startups can use these APIs to build personalized applications quickly and easily. Use cases span mental health, education, healthcare, and financial coaching domains extensively. Developers worldwide will be able to integrate behavioral AI into apps. This will create an ecosystem around Assessli's technology and platform.

The Billion User Dream

Suraj dreams of reaching 1 billion users globally by 2030 ambitiously. That goal might sound impossible but the data strongly supports it. Over 75 percent of ChatGPT users want personalized AI companions badly. People crave technology that understands their unique needs and contexts deeply. Generic AI leaves users feeling unheard and misunderstood frequently in interactions today. Assessli will become the foundational model for behavioral understanding worldwide in future.

The company will support 10 trillion privacy protected data points from users. Users will always remain in control of their personal digital twins. The LBM will power applications built by thousands of developers worldwide. The vision is to make personalized AI a basic right for everyone. Every person deserves an AI that truly understands them inside and out.

Inspiration For Kolkata Entrepreneurs

Suraj Biswas has powerful advice for aspiring entrepreneurs from Kolkata specifically today. First, do not let your location limit your global ambitions at all. Kolkata has world class institutions, talent, and a supportive ecosystem now growing. Build from here and compete globally without hesitation or fear of failure. Second, leverage the research institutions like ISI, IIT Kharagpur, and others. These institutions provide credibility, mentorship, and technical support that is invaluable always.

Third, focus on solving real problems rather than copying Silicon Valley. India needs homegrown solutions built for Indian contexts and global markets. Fourth, protect your intellectual property through patents early in the journey. Patents provide competitive advantage and investor confidence for raising capital funds. Fifth, build relationships with other founders and mentors in the ecosystem. The Kolkata startup community is collaborative and supportive unlike competitive metros.

Sixth, do not be afraid of rejection from investors or customers. Every no brings valuable feedback to improve your product and pitch. Seventh, reinvest early revenues into research and development rather than vanity. Sustainable growth comes from great products, not just great marketing campaigns. Eighth, represent Kolkata proudly on national and international stages with confidence. The city deserves recognition as a deep tech and AI hub.

Ninth, hire local talent and contribute to the city's ecosystem growth. Building a thriving startup scene requires collective effort from all founders. Tenth, stay humble and connected to your roots no matter how. Success comes from purpose, not pride or arrogance in achievements achieved.

Competing With Tech Giants Successfully

People often ask how Assessli competes with giants like OpenAI effectively. The answer lies in focus and unique positioning strategically in markets. OpenAI focuses on Artificial General Intelligence and language models primarily only. Anthropic and Mistral also build large language model architectures primarily for text. None of them train AI on individual human metadata exclusively like Assessli. None create personal digital twins that evolve with users daily over time.

Assessli's focus on behavior and biology creates a strong competitive moat. Accessing consented personal health data requires trust and real use cases. Generic chatbots cannot ask users for genomic or biosignal data easily. Assessli solves real problems that require personal biological information access and consent. This unique positioning makes Assessli different from all other AI companies.

Building With Privacy And Trust

Privacy remains absolutely central to everything Assessli builds and ships to users. All user data gets encrypted with strict consent controls applied at all. Processing happens near the user, not on distant cloud servers far away. People choose exactly what signals the AI can access and use. Trust forms the foundation of every single feature release cycle in development.

Suraj understands that without trust, personalized AI cannot succeed at all ever. Users must feel safe sharing their health and biological data completely. Assessli ensures data is never sold to third parties or advertisers. Assessli ensures users can delete their data anytime they want to. This commitment to privacy builds long term trust with users globally.

Lessons For Young Entrepreneurs Everywhere

Suraj's journey teaches powerful lessons to aspiring founders across India and worldwide. Start with a purpose bigger than just making money quickly or easily. Learn something new every single day without exception or excuse at all. View rejections as valuable data, not final permanent answers or failures ever. Protect user privacy and earn trust from day one onwards without compromise. Build products that help real people solve actual problems today right now.

Financial background does not determine success in entrepreneurship at all whatsoever completely. Persistence and clarity of vision matter more than initial resources or money. One biology chapter sparked a dream that changed Suraj's entire life. Hard work and smart decisions turned that dream into reality successfully. Young founders should focus on solving real problems, not chasing trends.

The Human Side Of Technology

Assessli represents a fundamental shift in artificial intelligence development philosophy and approach. Technology should understand and adapt to people it serves every single day. AI should listen first before giving advice or suggestions immediately to users. It should care about context, mood, energy, and biological state deeply. Students deserve learning experiences tailored to their exact cognitive patterns and needs. Patients need healthcare guidance based on their unique medical history and data. Workers require productivity tools that respect their natural energy rhythms throughout day.

Assessli brings humanity back into artificial intelligence development and deployment worldwide today. It shows that AI can be personal, caring, and truly helpful. It shows that technology can understand humans at a deeper level. It shows that the future of AI is personalized and human centric.
