For many years I've been taking jobs with earlier and earlier startups. For the last two I was even the first tech hire; at EquipmentShare.com (Y-Combinator) and then Sworkit (Techstars).
So now the only thing left is to start one myself ;)
I have a Trello board full of horrible ideas, but one or two there might just be the ticket.
I have always been drawn to community and transparency so Indie Hackers has a great mix where I feel very at home.
