“So back to the original question I posed at the beginning of this post. Can you build a business on browser extensions? Although a few companies have gotten into the market via extensions and gotten sold for good money, I think the answer is largely no. A browser extension is a smart way to enter the market, particularly if you want to reach power users early on, but you need to figure out how to build a broader service offering with your technology in order to reach a mainstream audience if you really want to build something big and sustainable.”
