# Surrey Street Partners

> Surrey Street Partners is a senior product practice that builds production technology in payments, open banking, capital markets, commerce, and AI. Two principals with 30+ combined years embedding with engineering teams to ship working software — not decks.

## What we do

Surrey Street Partners specializes in:

- **Payments & commerce**: Authorization models, headless commerce, multi-party transactions, vault architecture, SMS payments infrastructure, PLG-to-enterprise commercial transitions
- **Open banking & data sharing**: Financial data API platforms, CFPB 1033 compliance, consumer-permissioned data, fintech partnerships
- **Capital markets infrastructure**: Derivatives and futures trading platforms, market data systems, institutional product strategy
- **AI product strategy**: Production agentic workflows, ML-driven personalization, alternative data, AI-native product strategy
- **Physical workflow digitization**: Software eating industries where the offline complexity is the product (real estate, lending, last-mile)

## How we work

1. **Discover** — Understand your business, your stack, and the constraint that matters most. No prepackaged methodology.
2. **Architect** — Design systems that work in production. Every architecture decision maps to a business outcome.
3. **Build** — Write code, ship prototypes, and stand up infrastructure. Embedded with your team, working in your repos, on your timelines.
4. **Validate** — Every deliverable is tested against real users and real data. We don't hand off until it works — and you can prove it works.

Surrey Street Partners takes on a small number of engagements at a time. Typical engagements run 3–6 months with a defined scope. Best suited for:

- **Series A–C companies** that need VP-level product leadership without a full-time hire
- **PE-backed portcos** where the product function needs to mature quickly post-acquisition
- **Enterprise innovation teams** building net-new AI, commerce, open banking, or capital markets infrastructure inside larger organizations
