I've worked for startups for 30+ years. I've seen this industry from before the dotcom era into the cryptocurrency era (and I work in crypto now.)
Here's my perspective-
-- Experience is undervalued by people who don't have it. It is critical for a startup. You don't all have to be experienced, but get someone who has experience. One of the real killers of startups is bad management, and one of the causes of bad management is management by instinct, especially terrible is "type a" CEOs (to pick a stereotype for succinctness sake only) whose management history was being president of a frat in college, telling software engineers how to build product, but he knows nothing about software.
-- Experience as an executive who didn't start out as an individual contributor is not experience. If you cannot do your subordinates jobs, you cannot manage them effectively, unless you have a subordinate who can do the jobs (like a lead) who you manage.
-- Your CEO needs to be proficient in the unique value of the company. EG: If you are a sales organization you need to have a CEO who is a proficient sales person. Apple needed a proficient CEO when it was an engineering / product organization (and Steve Jobs was that- not as a good an engineer as Woz but he knew electronics and software development) ... but now Tim Cook is a proficient supply chain master and that's what Apple needs to thrive now. As a startup your CEO needs to be able to build the product. Or he will make bad decisions.
-- Founders give investors way too much power. They seem to think that investors are an old boys club that decides who wins and loses. In the valley for BS startups that's maybe true- you can get BS money until you make it. But if you're not a Golden Child then you need to get traction and revenue, and you always, always, want to be in the drivers seat for investment. You never want to need it.
I've seen so many VC and even lately angel deals with terrible terms that I'm convinced the reason being a founder is not as remunerative as it should be is founders signing bad deals desperate to keep the company going.
Always keep your burn rate low.
When I was making minimum wage in college I was ecstatic because I could afford to go see a movie in the theater every week. That was "luxury" for me. As my income grew, I kept my definition of "luxury" well below my income. This produced savings. Those savings helped greatly in lean times.
Run your business that way. You may be able to grow to 100 people now, but don't, grow to 70 or whatever, so you have more cushion.
If your hiring is ahead of your traction you're probably not hiring the right people anyway.
