Build the next great company with us
Martian Ventures partners with ambitious builders to create new companies from the ground up.
HOW WE WORK
Building companies with founders
We act as professional co-founders, providing funding, expertise, operational support, and access to our network. In return, we take a pre-seed investor-level equity stake and expect relentless commitment to building a great company.
Our goal is simple: increase the probability of startup success by focusing on what actually matters - validation, traction, and execution - while eliminating distractions that slow founders down.
PROGRAM PATHS
Two paths into the program
Join with an idea, or discover one with us — both paths lead to building a company together.
Founders-Market-Fit
For founders with deep domain expertise and an existing idea or opportunity.
We help refine the idea, validate it through structured experiments, and if traction is strong, we found the company together (founders typically hold 90%+).
Entrepreneur in Residence
For talented builders who want to become founders but don’t yet have an idea.
You join Martian Ventures for 6 months, work with us to discover and validate opportunities, and if traction emerges, we launch a company together (founders typically hold 85%+).
