Every Astronomic mentor is a post-exit founder — someone who has built a company, raised capital, and sold it. Not a corporate advisor. Not a consultant. A founder who has been exactly where you are.

The PEF Network
Astronomic's mentor network is powered by Post-Exit Founders (PEF) — a global community of 2,000 founders who have built and sold companies, primarily in tech. With 250 members in Austin and 1,500 in San Francisco, PEF represents the deepest concentration of real-world startup experience available to any founder.
The problem with most accelerator mentor networks is that the mentors are corporates who have never actually built a startup. Who better to coach you through your Series A fundraise for a B2B SaaS healthcare company than a founder who built, fundraised for, and sold a B2B SaaS healthcare company?

How We Match
Generic mentorship is noise. We match on four dimensions so that every session is immediately useful.
Strategic acquisition, PE buyout, acqui-hire, or IPO — matched by how your mentor exited, not just that they did.
Bootstrapped, VC-backed, revenue-based financing, or crowdfunded — your mentor has walked the exact same capital path.
B2B SaaS, healthcare, fintech, consumer, deep tech — matched by the specific market you are building in.
Fundraising, hiring, go-to-market, product-market fit, or M&A prep — matched by what you are working through right now.
Sample Mentors
James Rourke
Enterprise SaaS
"The hardest part of my Series B wasn't the pitch — it was knowing which investors to avoid."
Elena Vasquez
MarTech / Analytics
"I bootstrapped to $8M ARR before anyone told me I could raise. That path is underrated."
Ryan Chen
B2B SaaS
"Three exits taught me that the best acquirers are the ones already using your product."
Layla Khoury
Fintech / Payments
"Fintech due diligence is a different animal. I wish I'd had someone walk me through it."
David Mensah
Healthcare SaaS
"Healthcare sales cycles are 18 months. If you don't know that going in, you'll run out of runway."
Aisha Patel
B2B SaaS / Operations
"PE buyers want clean books, recurring revenue, and low churn. Build for that from day one."
