I had the opportunity to receive relevant angel investment to my newly born startup if I could find a cofounder (the investor asked me to not be a solo founder). The person that I chose was a close friend that I’ve worked with before, but deep down I knew he wasn’t really entrepreneurial material. In the end, he accepted, just to turn around and say “no” when we got the term sheet to sign (“it’s just too much work for me”). The investor aborted the offer. I’ve made a bad choice because he was my friend and I valued that above the business parameters. It was a terrible mistake.
