I wish I could upvote this more. I feel like the people who say that all you need is engineers have worked either exclusively at devtools type startups, or they've only worked at unsuccessful startups but have convinced themselves that the reasons why had nothing to do with lack of people with PM skills.

If you work in pretty much any kind of B2B SaaS and don't have PMs (or someone doing the PM work - if you've got engineers who were formerly PMs who spend half their time managing the roadmap, you can't really claim you're only employing engineers), you're probably doomed.
