Introducing

A consultancy built by the people who stay for the hard part.

See what we build

Most firms sell you a proposal. We are built for the eighteen months after it.

The people who understood the architecture were never the people who wrote the code.

Same names, same numbers, first call to final commit.

Staffing

Senior engineers only

Every engagement is scoped and delivered by engineers who have shipped this class of system before.

Access

No relay layer

Direct access to the people building your system — in your sprint calls, in your channels, throughout.

Commercials

Fixed-price clarity

Defined scope gets a fixed price and a fixed timeline. Change is priced openly, before it happens.

Exit

Documented handoff

We optimise for the day you stop needing us. Runbooks, decision records, operational ownership transferred.

Where we lead

Three practices carry most of our work.

In the work

This is what an engagement actually looks like.

   
Running 0.0s
pipeline main ● live run

Tests, CI and infrastructure-as-code from the first commit.

A pipeline that fails a build rather than a customer conversation.

Written so the engineer who inherits it can read it without a call.

Where we work from

Engineered in India. Built for global delivery.

TYPICAL WINDSORHARLOW KICKOFF HANDOVER

Rotations are your decision, not our resourcing convenience.

One firm, one stack

The layers most consultancies split across three vendors.

The handoffs are where projects die.

Split a feature across an AI shop, a cloud partner and a front-end agency, and the failure lands in the gaps.

Scope an engagement

We build the part your customers touch, trust, and never think about.

Capability index

Search the stack. If it is listed, we have run it in production.

Engagement models

Four ways to work with us.

Fixed scope

Project delivery

A fixed price and a real end date.

Stage 04

Hand off
