Question
For 3 years, I've been bootstrapping and signing up early adopters to be able to pay for developers to build out my SaaS product. The development process has been the "kink in the hose" so I've been working a decently paid full-time job while it gets built. My schedule was not holding up the progress since it was all development (and I'm not a developer). But within the next three months, we will have finished the build and will be delivering the product to our first three customers.
At that point, I have to assume that my schedule WILL be what is holding us up - and that doesn't sit well with me. How should I plan for this? What are the options?
Answer
Been bootstrapping a HaaS company for 3+ years after quitting my job. Some good SaaS-specific advice has been given above but the fact you've been struggling to develop a finished product in 3 years, which is almost an eternity in software, sounds alarming. I'd look into this oddity and assess your execution capability if you switch to full time. It does liberate you and definitely advances your business faster but doesn't make you a super hero either.
Also, consider the typical financial advice: don't quit before you have a 6-12 months cushion to face tough times. SaaS is hard.
