The most common post YC failure case for the companies we fund, is they're incredibly focussed during YC on their company... and after they start doing a lot of other things. They advise companies, they go to conferences, whatever.

... but actually it sucks to have a lot of employees, and you should be proud of how few employees you have.

In general though, if you look at the track record of pivots, they don't become big companies.

Employees will only add more value over time.

I think the best thing you can do is be aware that as a first time founder you are likely to be a very bad manager.

Starting a business is like riding a wave between life and death. If you can hang on long enough, you're bound to succeed

Great execution towards a terrible idea will get you nowhere.
