We can speculate around someone's motivations all day, but no one can speak for this engineer but themself, and it sounds like they would (understandably) prefer to keep private matters private. At the end of the day he probably got an offer more favorable than his current package in some dimension that's important to him. Boring answer but it is what is. Earlier stage often means opportunity for more equity... That said, Roam itself appears really small and only to have just raised 9M ~9 months ago. So they are likely either raising their next round now / imminently. As someone with no horse in the race, I do not think it says anything about Roam itself. The average employee tenure at a startup is ≤ 12 months and I want to say the actual figure is ~9 months so this isn't particularly unusual. One potentially interesting question might be, does Roam have a non-compete [and will they attempt to enforce it]? But it looks like they are based in SF... so probably not. Another potentially angle is to research the background of the new startup's founders. It looks like Athens' product is open source [1] while Roam's is not. That can be substantial to a lot of the engineers at the end of the day. [1]: https://github.com/athensresearch/athens https://github.com/athensresearch/athens
