It's very hard to know upfront -- what made us interested in Indie Hackers wasn't just the idea per se (we'd thought about it before and looked at other sites in the past), but rather the fact that it was executed so well. There are tons of things that we'd in principle be open to acquiring if the right company existed. In general, we look for small, highly-effective technical teams with a very high bar for execution quality. (Indie Hackers, which was pretty much just Courtland operating solo, cleared this threshold by a significant margin: https://twitter.com/Shpigford/status/851851923502268416) To the extent that the team really understands either developer tools or startups, that's a bonus.
