Series A and later
We invest after product-market fit, before the outcome is priced in — the protostar phase, between formation and ignition.
A venture syndicate
Protostar gives high-net-worth investors and family offices direct, deal-by-deal access to growth-stage technology companies — allocations normally reserved for institutional funds.
The model
We invest after product-market fit, before the outcome is priced in — the protostar phase, between formation and ignition.
No blind pool. LPs see the company, the terms, and the thesis before committing a dollar, with no obligation to participate.
The firm invests alongside its LPs in every syndicate, on the same terms.
