Ryukin Ltd, software development house, United Kingdom

Systems that stay correct under load.

Six years building crypto and AI systems, independently or combined, alongside workflow automation for established businesses. Scoped, priced and delivered by the team that builds it.

Where we work

We build the hard end. Real-time, high-throughput, correctness-critical.

AI-assisted generalists have compressed the price of CRUD applications. They have not touched this.

Where the two meet

Crypto and AI, independently or combined.

The two specialisms are not separate businesses. The hardest systems we have built are both at once: a real-time market data pipeline with a model layer on top of it.

Our longest-running engagement combines years of historic trade data with live ingestion across multiple exchange accounts, then runs AI analysis over the result. Every calculation returns in one to two seconds no matter how much history sits behind it. Neither half of that is interesting on its own. Together they are the whole problem.

CRYPTO AI RESPONSE TIME HOLDS AS DATA GROWS

Record

Six years independent, profitable throughout.

£1.5m+

Delivered, sourced and priced independently.

6 yrs

Running Ryukin Ltd, profitable throughout.

10+ yrs

Building production software, including at BNY Mellon.

Background

Large-scale real-time systems on Kubernetes at a global custodian bank, under regulatory scrutiny.

Seniority

Senior and principal engineers only. No junior leverage, and nobody learning on your budget.

Capacity

A core team plus a vetted developer network, so £100k+ builds run on real timelines rather than one at a time.

Stack

We build in whatever the system actually requires. Technology is chosen to fit your environment and your team, not our preferences.

Access

You deal with the engineer building it, not an account manager.

Confidentiality

All client work is under NDA. Everything here is described by capability, never by client.

Engagement

Fixed scope, fixed price, written down first.

  1. Scoping call to establish what you need and whether we are the right fit.

  2. Written scope. Fixed price, staged payments, changes quoted separately.

  3. Build and deliver, with direct access to the engineer.

  4. IP transfers to you on final payment.

Most clients stay on a monthly retainer afterwards. The longest engagements have run for years. Not a fit for unfunded projects, equity-only arrangements, or work priced at the bottom of the market.

Next

Most first builds become ongoing engagements.
