What we do
Four things, done end to end.
From discovery to production and the months after. One team owns architecture, product, delivery and support, so nothing falls between vendors.
01
Exchange and gateway products
Signup‑to‑activation flows, identity verification, checkout and payment routing for crypto exchanges, fiat on‑ and off‑ramps and B2B FinTech. Measured on conversion, approval rate and retention, not on features shipped.
02
On‑chain data and trading infrastructure
Parsers, streams and APIs that turn raw Solana transactions into decisions in milliseconds. Trading systems with risk controls, inventory management and historical replay. Hyperstream is the productised version.
03
Custom Web3 development
Contracts, front‑ends and back‑ends built by senior engineers, audited and tested before they touch mainnet. Solana first, EVM when the project needs it.
04
Product and delivery operations
A product manager inside your team who owns the backlog, the specs and the rituals. Spec‑to‑release in ten days instead of four weeks, across several products at once.

How we work
Weekly releases, one accountable team.
Fixed‑scope projects or a dedicated team on a monthly rate, priced in writing before we start. Direct access to the senior engineers and architects doing the work.
Weeks 1–2
Discovery
Jobs to be done, customer journey, architecture and a PRD you can put in front of investors.
Every 1–2 weeks
Build and release
A dedicated squad of three to eight. Every release is tested, reviewed and deployed with a rollback path.
Ongoing
Run
Monitoring, 24/7 support across time zones, and the same people who built it answering the pager.
The studio
Thirty people across Europe and Asia. Registered in Singapore. Building for crypto since 2017.
Engineers, designers and product managers who have shipped exchanges, gateways and trading systems as operators, not only as vendors. We take on a handful of clients at a time and stay for years.
