Creator commerce
GateKeep
A storefront and attribution product for creators who want a faster save flow, more expressive storefronts, and clearer visibility into how commerce turns into income.
Independent product studio
Greenwich Street Studios
We build small, sharp software products where trust, taste, and operator judgment matter. The studio is intentionally quiet about individual identity and loud about the work.
Formed in Massachusetts
Private by default
Shipping in public, selectively
Current work
Projects under the studio roof
The site avoids personal biography by design. These are product lines, prototypes, and research surfaces the studio is shaping.
Decision training
PokerReads
A private training surface for reviewing poker decisions, organizing notes, and turning repeated spots into better judgment over time.
Playful utility
CarSpotter
A lightweight app for car recognition and collecting visual observations. It is intentionally fun-first, not a revenue surface.
Public-interest systems
Case Transparency Tools
Internal tooling experiments for collecting case context, managing source material, and making review workflows more deterministic.
Operating style
Small teams, durable surfaces
Privacy is part of the product
Public pages should reveal what the studio is building, not the personal details of the operator behind it.
Ship the working surface
The studio favors concrete workflows, audits, and repeatable systems over vague strategy decks.
Trust compounds through clarity
When money, data, or user identity is involved, the software should explain what is happening plainly.
Studio contact
Use the studio identity, not a personal one.
After the domain email is configured, Apple, D&B, partners, and product inquiries should route through the studio address.
