Rajan Randeva signed up to Amazon Associates, obtained an API key, and pulled data from approximately 1.8 million products. ChatGPT then used that data to generate blog content, published across 36 active websites he had purchased specifically for their domain authority and backlink history — allowing them to rank highly on Google and sometimes outrank Amazon itself. At peak, in December, the network was moving around 30 treadmills per day.
The technical foundation is straightforward: Amazon Associates provides both the affiliate tracking and the product API. By connecting to that API, Randeva ingested roughly 1.8 million product listings — a dataset large enough for ChatGPT to generate targeted, keyword-rich blog posts at a scale no human editorial team could match.
The distribution strategy is what gave the model its edge. Rather than launching new domains from scratch, Randeva acquired existing websites — paying up to $500 per site — chosen specifically for their established domain authority and backlink profiles. That head start meant freshly published AI content could index quickly on Google, bypassing the typical months-long sandbox period for new sites.
The timing was deliberate. December's New Year fitness surge translated directly into high-intent search traffic for equipment like treadmills. With 36 active websites feeding that demand simultaneously, the network was converting around 30 treadmill sales per day at its peak.
Over the first three months of operation, the platform generated £300,000 in total revenue — roughly £100,000 per month. That figure came entirely through affiliate commissions: no inventory, no fulfilment, no customer service.

"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, The Brain & FlexVision.
Rajan is 19 years old and has been building businesses since the age of 11, when he launched his first dropshipping site. His Amazon affiliate venture (operating under FlexVision) generated £300,000 in its first three months, before he pivoted to building The Brain — an AI intelligence layer for SMEs. He attended a Boston programme with MIT and the Welsh Government at 18, and comes from a family with deep roots in entrepreneurship: his parents run a luxury vehicle brokerage business.
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 any question about their own company's data, essentially acting as ChatGPT for your business.
Rajan launched his first business at age 11 with a dropshipping website selling products from China, making one sale before closing it down. After finishing his GCSEs, work experience at Supply Life inspired him to build the Amazon affiliate platform that would generate £300,000 in three months.
Dan is a self-described "big advocate of the apprentice system," arguing that it provides practical experience combined with learning simultaneously — giving candidates a meaningful edge over those coming through a traditional university route.
