ViVaNeighbors did not begin in a boardroom or a tech accelerator. It began with one person lying on a kitchen floor — and the realisation that everything needed to help her was already there. It just wasn't connected.

Help Society. Build Community.
ViVaNeighbors began not in a boardroom or a tech accelerator — but on a quiet street in Sawston, Cambridgeshire, in the winter of 2025.
Our founder's elderly friend — who lived just 100 meters away — had fallen in her kitchen. She lay there for nearly four hours before anyone knew. Her family lived two hours away. Her phone was on the counter, out of reach. Her neighbors — good, caring people who would have rushed to help — had no idea anything was wrong.
That night changed everything. Not because it was unusual — but because it was so entirely preventable. The technology to connect her to her neighbors in seconds already existed. The willingness of those neighbors to help already existed. The care was already there, just 100 meters away.
All that was missing was the system to bring them together — fast, simply, and without needing a phone. ViVaNeighbors was built to be that system. It took six months of design, testing, and deep community listening to get it right.
"She didn't need a hospital that night. She needed someone 100 meters away to know she was on the floor. That gap — between someone who needs help and someone ready to give it — is exactly what ViVaNeighbors exists to close."
— Founder, ViVaNeighbors · Sawston, CambridgeshireThe people 100 meters away would have been there in minutes — if only they had known. The willingness to help was never the problem.
Already existedIoT, Bluetooth, mobile alerts — the technical capability to connect a vulnerable person to their neighbors in seconds had existed for years.
Already existedA simple, trusted, single-press way to reach the right person at the right moment — without needing a phone, an app, or a password.
This was missingXL Venture was founded with one clear objective — to create products and services that genuinely help society. Not as a side effect. Not as a marketing position. As the primary reason we exist.
We are not a technology company that happened to find a social problem to solve. We are a mission-driven company that asked a question — how can we use what we know to make life better for people who need it — and then built the answer.
ViVaNeighbors is that answer. A product shaped not by market opportunity, but by genuine belief that communities should look after their own — and that the right technology can make that possible again.
Rebuilding the bonds between neighbors that modern life has quietly eroded — one street at a time
Creating practical, human-first systems that give vulnerable people real help from real people
Using it as a tool in service of people — not as the point in itself. Simple, purposeful, human.
A Cambridge-based venture with a mission to create technology that helps society and builds genuine community — starting with the street you live on.
ViVaNeighbors was not built by someone who spotted a market gap. It was built by someone who spent decades watching the world — and decided it was time to do something about what he saw.
Founder, XL Venture
Sujan Bhattacharyya brings decades of professional consulting experience to XL Venture. Over a long career advising organisations across industries, he developed a rare and deep understanding of how institutions, communities, and people actually function — and where the gaps between them lie.
Across those years, one pattern kept emerging — the most important problems facing society were rarely the ones attracting the most attention or investment. The gap between what technology could do and what it was actually being used for was growing wider, not narrower. And communities — the real, human ones — were quietly fraying.
That observation, held and refined across a long career, eventually became something stronger — a conviction. That it was possible to use technology not to replace human connection, but to enable it. Not to monetise loneliness, but to end it. Not to create dependency on systems, but to rebuild trust between people.
That conviction became XL Venture. And XL Venture built ViVaNeighbors. A product shaped by someone who has spent a career understanding how organisations, communities, and people work — and what they truly need.
"The technology was never the hard part. The hard part was believing that people — given the right tool and the right reason — would choose to show up for each other. I believe they will. ViVaNeighbors is built on that belief."
— Sujan Bhattacharyya, Founder, XL VentureCambridge is not just a postcode. It is an ecosystem — of thinkers, builders, researchers, and people who believe that ideas genuinely can change the world. It has a long tradition of turning careful, rigorous thinking into real-world impact.
XL Venture sits within that tradition. We are a focused team with a large ambition — grounded in one of the world's great cities for innovation, and motivated not by the next funding round, but by the next vulnerable person who needs a neighbor at their door.
Cambridge also reminds us every day that the best ideas are simple at their core. Complex to build, perhaps. But simple in what they do. A button. A neighbor. That simple.
An ecosystem built on rigorous ideas and careful reasoning
A city that turns conviction into products that matter
Thinking that starts local but reaches everywhere it's needed
A city that understands the value of human connection

Not a mission statement written for an investor deck. A genuine reason for existing — that shapes every decision we make.
Technology in service of people — not the other way around. Every feature we build is asked one question first: does this make someone's life genuinely better?
We are not just connecting devices. We are connecting people. Building the bonds between neighbors that have been quietly lost — and making them practical and lasting.
Our measure of success is not just alerts sent — it is loneliness reduced, crises prevented, and vulnerable people who feel genuinely supported by the people around them.
"What would it take for a vulnerable person — elderly, unwell, recovering, pregnant, afraid — to have a real human being at their door within minutes, at any time of day or night, without navigating technology, without calling a stranger, and without being a burden on already stretched emergency services?"
The answer was deceptively simple. A button. And a neighbor who said yes. Everything else — the IoT device, the consent model, the SMS alert, the neighbor network, the companion app — exists to make that one human moment possible. A person at a door, because another person asked them to come.
These are not words on a wall. They are the lens through which every decision at XL Venture is made.
Technology is a tool. People are the point. Every decision starts and ends with the human being on the other side of it.
"People are the point."We never sell data. We never track location without consent. Alert data deleted within 24 hours. Privacy is not a feature — it is a foundation.
"Built in from day one."We measure success by the connections we create — not just the alerts we send. A safer street is the goal. A community is the result.
"The street is the product."Every vulnerable person deserves support that feels human — warm, personal, and chosen. Not transactional. Not bureaucratic. Not a service.
"Support, not service."We exist to help society. That is not a tagline or a positioning statement — it is the business model, the product, and the team.
"Why we get up in the morning."The most powerful solutions are the ones anyone can use. One button. One press. That simplicity is not an accident — it is the hardest thing we built.
"Simple is the hardest thing."We are a small, passionate team of technologists, community builders, and social impact specialists — united by the belief that neighbors can save lives.
Built ViVaNeighbors after witnessing first-hand the gap between technological capability and community care on a quiet street in Cambridgeshire. Driven by a single mission: no one should lie alone when help is 100 meters away.
Software architect with deep experience in health technology, BLE, and IoT systems. Leads all technical development with a focus on reliability, security, and simplicity under pressure.

We are a small, early-stage team doing important work. If you are passionate about community, technology, and social impact — and you want to help build something that genuinely matters — we would love to hear from you.
Get In TouchAn honest account of how ViVaNeighbors came to be — and where we are going.
Our founder's elderly friend — just 100 meters away in Sawston — falls in her kitchen at 11 PM and lies there for nearly four hours before anyone knows. The technology and the willing neighbors already existed. The connection didn't. ViVaNeighbors begins to take shape the following week.
Six months of intensive design work, community conversations, and research into loneliness, social isolation, and IoT-based care systems. We speak to elderly residents, carers, housing managers, and healthcare workers to understand exactly what the system needs to be.
The core ViVaNeighbors platform is built — the subscriber app, the consented neighbor alert system, the IoT button integration, and the privacy-first data architecture. Tested internally and with a small group of volunteer households in Sawston.
ViVaNeighbors is live and in continuous improvement. We are actively building our first communities in the UK, developing institutional partnerships with housing associations and healthcare providers, and preparing for our India launch.
Scaling across UK communities and launching in India — starting with urban centers where isolation and rapid urbanisation are creating new vulnerabilities. Building formal partnerships with NHS trusts, housing associations, and Indian community health organisations.
With a proven, evidence-based model built in the UK and India, we intend to expand into further markets — guided by where we can make the greatest difference to the most vulnerable communities. The mission grows. The work continues.
These are the convictions that drive every decision we make at ViVaNeighbors.
It kills more people than obesity. It costs healthcare systems billions. It destroys quality of life for millions. And it is entirely preventable with the right tools and the right will.
Most people want to help their neighbors. They just don't know when they're needed, or how. ViVaNeighbors gives them the when and the how — instantly.
The best use of IoT and mobile is not to automate human connection — it is to enable it. Our system exists to bring two human beings together. That's it.
When we make something needlessly complicated, we are saying — without words — that the people who struggle with complexity don't matter to us. We refuse to say that.
Professional services are vital. But neighbors are faster, warmer, and already there. The future of social care is a blend — and community must be at its heart.
The anonymity of modern urban life is not inevitable — it is a design failure. ViVaNeighbors is one part of redesigning how we live alongside each other.
Whether you join as a subscriber, a consented neighbor, a partner, or a future team member — you are part of rebuilding the kind of communities where nobody is left alone.
