I am potentially looking for a co-founder but am not entirely sure if it would be a good idea. I own a fledgling revenue-oriented transactional SaaS startup in a niche. Volume is low, margins are high, acquisition prospects are good if we can get rolling. Bootstrapped, started as a side project a couple years ago. Have a web app in production but finding good talent and financing the development has been challenging. Most contractors either price out of my budget or get cold feet about learning their way around the somewhat complex code base. Right now operating without a developer at all. Have some customers and a highly lucrative partnership in the final stages of negotiation (worth as much as $40K/week) but it's unlikely I'll be able to close on the deal if I can't line up some ongoing dev help. On one hand, I'm committed to seeing this through by whatever means necessary. On the other hand I have a bit of a sunk cost problem and am not sure, given the amount of work and money that has gone into the product thus far (and modest angel investment), that I could reasonably part with enough equity to interest a "co-founder." About me: tons of domain experience and contacts, highly product-focused, self-taught developer (have written reasonably large portions of the code base for tasks that I'm capable of coding well).
