The way VC investments work is that it's all very incestuous. Google, MS, etc. have lots of money in VC funded AI startups. Instead of letting them fail the hard way, they usually fail in a soft way via mergers, acquihires, etc.

Mostly when you read about a big company buying a small startup, it's actually an investor bail out. The company has technically failed and the investors basically want to get rid of the failing company in a way that doesn't make them look like muppets. So there's a nice press release, an undisclosed share swap, and tada another successful exit .. of a company and technology that you will never hear from again. This is nothing new. This is what happens to most startups that don't IPO.

Codium was alright a few years ago but by now it's a commodity. Amazing idea of having a little side bar in VS code with a bare bones chat UI that you could hookup to your openAI API key. They build bits and pieces of tech with some merit to it since then of course. But nothing that cannot and is not being replicated by others. Same with Cursor, windsurf and all the other niche players in this market. None of these companies has much of a moat.

And at this point all the big companies have their in house built solutions: Claude Code, Google has Julius, OpenAI has codex, MS has co-pilot, AWS recently launched their own thing. Clearly building these things is not that hard. All the IP is in the models and infrastructure.
