I bootstrapped a SaaS business from my kitchen table...it's now worth just shy of $100M.
I thank the heavens everyday that I didn't go the VC route. I can pretty much do whatever I want without this constant growth at all costs pressure. It also gives us a massive advantage against VC backed competitors. We can make decisions that reap benefits 2-5 years out.
This has created a situation were every competitor follows the same trajectory where it eventually leads to an over-complicated, bloated product that users hate. They come to us and it's like a breath of fresh air.
I have a $100M SaaS in a different space but the underlying tech is identical. I had this idea ~10 yrs ago when we first started writing our own import logic to move users over from competing services.
The engineering challenges to make this work flawlessly is going to be substantial to say the least. I GET from ~70 data sources right now...I couldn't imagine having to GET,POST, CHECKPOINT and DIFF with all the edge cases that appear.
Best of luck but this is a very hard problem to solve. Would love to see someone see this through!
I built a $100M SaaS. Do you want this more than anything? Are you willing to do do whatever it takes and go 1-2 years without a salary?
If you answered yes then you just need to leap and iterate on the user feedback loop.
My first mvp compared to what I'm selling today is completely different. I pivoted 20 times at least.
So the name of the game is to just start building and not be overly concerned with making mistakes. Find what doesn't work and move toward what does. Mimic nature by constant evolution.
I spent 10 years creating failure after failure...learning many things a long the way...at 27 my co-founder and I started a SaaS that is now worth $100M...we made $475 our first month which was roughly 10 years ago
