I’m surprised my approach wasn’t mentioned: bootstrap with consulting revenue. It’s not novel (it’s how 37Signals bootstrapped Basecamp back in the day).
The ideal way is to provide a service that aligns with the product so you can deliver under the same brand.
In my case I’ve consulted as a fractional Product lead[2] since 2007 to bootstrap my product businesses. Consulting has allowed me to support my family and provided as much runway as necessary before the bootstrapped business could support me full time.
One criticism of this part-time consulting approach is that it distracts from the product. This is not true if you’re delivering a service that doesn’t compliment the business.
But ironically probably more than half the founders i know are in permanent fundraising mode for companies that probably shouldn’t have raised in the first place. I look at consulting as a higher probability form of fundraising and see time spent on it as little different than fundraising for the “traditional” angel or venture funded company.
