Chrome Extension Agency
Build custom Chrome extensions for B2B SaaS as a productised service
Build custom Chrome extensions for B2B SaaS as a productised service.
Day-to-day work involves collaborating directly with clients to identify their specific needs for Chrome extensions, developing the extensions using JavaScript, HTML, and CSS, and testing them to ensure they integrate seamlessly with existing SaaS platforms. You’ll also handle client communications, project management, and marketing to attract new leads, all while maintaining a schedule that balances coding and client interaction.
This is the perfect time to start a Chrome Extension Agency due to the growing reliance on B2B SaaS products, with companies looking for tailored solutions to enhance productivity and streamline workflows. As digital transformation accelerates, businesses are increasingly seeking custom integrations that can set them apart, making now an opportune moment to tap into this niche market.
Ideal founders are tech-savvy individuals with a background in web development and an understanding of the B2B SaaS landscape. Realistically, you should expect to dedicate 15-20 hours per week to build your portfolio, engage with prospects, and deliver projects, especially in the initial stages as you establish your reputation and client base.
In the first 12-24 months, the potential upside can range from £36,000 to £180,000 in revenue, depending on the number of projects secured and the complexity of the extensions. With a solid marketing strategy and a growing network, you could scale your efforts significantly, potentially leading to recurring revenue through maintenance contracts.
