Great companies
start with a system
Startup Garage is a London-based venture building studio. We ideate, validate, and build companies in-house — then recruit founding CEOs to lead them and back them from first cheque through Series A.
Three rules,
applied every time.
Ideas are cheap
Every concept faces the same thesis pipeline and kill criteria. Most die on the whiteboard — by design.
Evidence decides
Prototypes reach paying customers in weeks. Signed demand — not opinion — earns a venture its build.
Founders finish it
We recruit founding CEOs into validated businesses and stay on the board through Series A.
Five years,
one playbook.
The garage opens
Studio founded in London with a first fund and a two-person bench, backed by a small group of operator angels.
First spin-out
Northwind Pay incorporated with a founding CEO recruited from outside the studio and pre-seed capital committed on day one.
The playbook hardens
Kill criteria, paid validation sprints, and the 20-week whiteboard-to-spin-out cadence formalized into a repeatable process.
Portfolio compounds
Eight ventures live across four sectors; the first Series A raised by a studio company, led by a tier-one European fund.
Twelve and counting
12+ ventures built, $40M+ in follow-on capital raised across the portfolio, and a second studio fund underway.
