The connective tissue of modern business systems — APIs designed properly, third-party services integrated faithfully, and data that flows between your tools without a human in the middle.

What we do

01

Bespoke API development

Versioned, documented, validated APIs that other systems — and future teams — can build on with confidence.

02

Microsoft 365 & identity

Email, calendars and sign-in wired through Microsoft Graph, so your platform lives inside the tools your organisation already runs on.

03

Payments & billing providers

Stripe and payment integrations treated as financial software — idempotent webhooks, provider-as-source-of-truth, and reconciliation built in.

04

Industry & legacy systems

CRMs, suppliers and the systems nobody wants to touch, connected through careful contracts and defensive engineering.

05

Data synchronisation

One source of truth per fact, with everything else derived — ending the version-of-the-truth arguments between your tools.

06

Webhooks & event flows

At-least-once delivery, retries and audit trails handled correctly, so a missed event never silently becomes a missing order.
