We are a different kind of co-founder.
Nebula Startup School builds enduring companies — from prototype to scale-up. We take ownership of validation, product, fundraising, and go-to-market alongside you, so you can stay focused on the vision that started it all.
Whatyouleavewith.
You don't just leave with a certificate. You leave with an incorporated entity, a working MVP, and a data room an investor will actually open.
How founders work
You'll pick up the day-to-day habits that separate founders who ship from founders who plan.
Proof there's a market
Test your assumptions and find real demand before you write a line of code.
People who've done it
You build next to founders and fractional operators who have already scaled a company.
A working product
Your first version, shipped in weeks and built to be used — not just demoed.
A raise-ready story
A data room, a financial model, and a pitch that holds up under investor questions.
A way to grow
Repeatable channels, pricing that works, and a path to your first real revenue.

We meet founders where they are. Whether you're at the napkin sketch or scaling past your first round, there's a way in.

Ninety percent of founders quit before they start. Most don't fail for lack of effort — they fail for lack of structure. Here's the structure we run.
Whichoneoftheseisyou?
We work with five kinds of founder. Each gets a path built around their starting point — not the same lecture on repeat.
