A venture syndicate

Invest before ignition.

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

A syndicate built for allocators.

01

Series A and later

We invest after product-market fit, before the outcome is priced in — the protostar phase, between formation and ignition.

02

Deal-by-deal

No blind pool. LPs see the company, the terms, and the thesis before committing a dollar, with no obligation to participate.

03

Aligned capital

The firm invests alongside its LPs in every syndicate, on the same terms.

Representative deal flow

Companies with open allocations.

  • ICON

    Construction tech

    3D-printed construction at housing scale. $500M+ raised; investors include Norwest Venture Partners and Tiger Global.

  • Paradromics

  • Vollebak

    Material science
