15 years ago after the funding I'd arranged to start a company fell through after about a year of travelling to raise it...we finally went to a VC. He insisted that he could not sign an NDA because of the precarious position it put him in hearing so many of these pitches. At that point we figured, this was basically our last option anyway so we gave him the pitch.
He really liked it and wanted a local company to build it that we weren't comfortable with, so we parted ways.
5 years later I found out he had the company build it about as well as he could from memory of our pitch. It had plenty of flaws but it was a company that ended up selling for several million. As far as I can tell, it was re-sold and the company had a complete shift of focus afterwards.
Meanwhile, in NY 2 years after my meeting with the VC an enterprising group of people who were not affiliated with that VC at all pursued and built a business out of one of the core features of my original platform. As it turned out, that feature stood as a business on it's own. I'd included it in the overall system because as an integrated feature, it facilitated a lot of efficiency gains.
My platform was a comprehensive information system for public schools designed to make it easier for teacher's to focus on their students, reduce their workload and make it easier for them to communicate directly with parents. As a part of that system, there was to be a market place for teachers to sell and exchange lesson plans. This was back in 2003 and now smaller companies have popped up doing various parts of what our original plan was for.
In NYC, Teachers Pay Teachers has made a business out of that aspect and for what it's worth, I'm really happy that they have been successful.
The whole experience was really eye opening and I've been extremely reluctant to pursue funding for any of my business ideas because of it. I wish that wasn't the case.
