Build a paid browser extension solving a sharp pain (LinkedIn enrich, Notion shortcut).
Day-to-day work involves identifying user pain points, developing the extension, and managing customer feedback. You'll need to continually iterate based on user suggestions and performance metrics, engaging with your user base on platforms like Twitter and Product Hunt. Additionally, you'll handle marketing, customer support, and billing processes as you grow.
Now is the ideal time for a paid browser extension due to the increasing reliance on web tools for productivity and networking. As remote work persists, professionals seek efficient solutions to streamline their workflows, especially on platforms like LinkedIn and Notion, which have become pivotal in the UK business landscape.
As a founder, you should have a basic understanding of coding and UX design to build the extension yourself. Expect to dedicate around 10-15 hours per week initially, ramping up effort as you refine the product and engage with early adopters. A passion for solving user problems in the digital space is crucial.
With a well-targeted extension, you could see monthly recurring revenue of £500–£2,000 within 12-24 months, especially if you capture a niche market. If successful, the potential for scalability exists as you can expand features or target different user segments, significantly increasing your user base and revenue.

The UK workforce is increasingly reliant on digital tools, and the demand for productivity solutions has risen sharply post-pandemic. Browser extensions that simplify complex tasks or enhance existing platforms will resonate well with users looking for efficiency.
Your primary customers are UK professionals, freelancers, and small business owners who heavily use platforms like LinkedIn and Notion. They are tech-savvy and willing to pay for tools that save them time and improve their productivity.
The UK productivity software market was valued at approximately £5 billion in 2022 and is expected to grow significantly. With millions of LinkedIn users in the UK, even a small percentage converting to paying customers can lead to substantial revenue.
