What is The Brain, and what problem does it actually solve for business founders?
The Brain is an AI intelligence layer that sits on top of the tools a business already uses — such as Stripe and Xero — allowing founders to ask plain-language questions and receive instant answers drawn directly from their own business data. Rajan Randeva describes it simply as "ChatGPT for your business": a tool designed to give founders their time back, rather than leaving them chasing accountants or waiting on unavailable staff.
The core problem Randeva is solving is the friction founders face when trying to access insights from their own operations. Instead of logging into multiple platforms, compiling reports, or waiting on a third party, a founder can ask a natural-language question and get an answer immediately. The intelligence layer connects to existing software the business already runs — no migration, no new stack — which removes the usual barrier to adoption.
One design principle Randeva emphasises is data isolation: each business's data remains entirely separate and is never shared or interconnected with other businesses on the platform. This matters particularly for founders cautious about where their financial and operational data ends up when using AI tools. You can hear him explain the concept in full on The Purpose People Podcast on Listenly.
"I started to build the Brain, which is an AI intelligence layer that sits on top of the tools that your business uses. You can ask any question — it's essentially ChatGPT for your business."
— Rajan Randeva, Founder of The Brain
As Randeva uses the term, an AI intelligence layer is a software layer added on top of existing business tools — in this case platforms like Stripe and Xero — that reads the data those tools already hold and makes it queryable through plain language. Rather than replacing existing software, it sits between the data and the founder, acting as an always-available interpreter.
About Rajan Randeva
Rajan Randeva
Founder, The Brain & FlexVision
Rajan Randeva is a 19-year-old entrepreneur who started his first dropshipping business at age 11 — before most people his age had given a second thought to income. After completing his GCSEs, he did work experience with his uncle at Supply Life, a UK food and supplements brand, which sparked the idea for an Amazon Associates affiliate marketing business he subsequently built under the name FlexVision. That operation generated £300,000 in revenue across its first three months, at one point running 36 active affiliate websites simultaneously and selling approximately 30 treadmills per day during December's New Year sales period. At 18, he was selected to attend a trip to Boston alongside MIT and the Welsh government — an experience that shaped his thinking about technology and ambition. He comes from an entrepreneurial family: his parents run a luxury vehicle brokerage business, which is where he first encountered the rhythms of running a company. The Brain is his latest venture, applying AI to a problem he observed first-hand — founders spending time chasing data instead of acting on it. Around 95% of his professional network consists of people roughly double his age, a fact that reflects how quickly he has moved into serious business circles.
