Developer platforms and internal tooling — the software your engineers stand on.

Typical timeline 8–16 weeks to first production release

01 The problem

What actually breaks here

Tools for engineers fail differently: your users can read the stack trace. Generated code nobody wants to maintain, internal platforms that drift from the workflows they were built for, and AI tooling that demos well but cannot be trusted with tenant boundaries. Developer tools earn adoption or they die — nobody can force an engineer to like a platform.

What we build

Internal platforms and agent systems with organisation-scoped retrieval, because a filter you forget is a data leak. Document-intelligence pipelines, where a model's output has to be coerced, confidence-scored and reconciled before anything downstream is allowed to trust it. Developer-facing APIs with contracts, versioning and error messages written for the person debugging at 2am.

02 Where we stand

Proof, not adjectives

Software you can inspect, and work we can describe.

In production since 2025

Dev13 Systems

The operating system an agency runs on, with AI built into the data rather than bolted beside it. CRM through to cash — accounts, deals, proposals, contracts — then native projects with work items, cycles and worklogs, HRM and payroll records, a multi-currency finance module built on a service catalogue, plus LMS, recruitment, OKRs, a wiki and a client portal. Twenty-five specialist agents across sales, delivery, engineering, marketing, talent and internal ops work over the same organisation-scoped store, so an agent answers from the agency's own accounts, projects and documents instead of from a chat window that knows nothing about them.

XBuilder

An AI takeoff platform for construction estimating. It reads a PDF floor plan and returns structured quantities — rooms with areas and perimeters, openings with widths and heights, dimension chains and building sections — which an estimator exports as CSV or JSON and bids from, instead of measuring the drawing by hand.

Population statistics for any polygon a user can draw

Demographic data existed as national tables and raster files. Answering "how many people live inside this shape" meant a GIS specialist, a desktop tool and a manual export, so a question that took a customer ten seconds to ask took days to answer — and could not be sold as a product.

03 Build or buy

When an existing product beats a build in Dev Tech

We would rather tell you this now than three months in.

Bespoke software compared with Dev Tech SaaS
Dimension	Building it	When Dev Tech SaaS works
Fit to your process	Built around how you actually work, including the parts that are unusual.	Fits if your process is close to the industry norm — and many are.
Time to first value	Weeks. Nothing works until the first release.	Days. This is the real advantage, and it is a big one.
Ongoing cost	You own the code and pay to maintain it.	Per-seat forever, but somebody else carries the maintenance.
Integrations	Whatever you need, including the internal system nobody else has.	Whatever the vendor supports. Check before you commit.
When it breaks	You decide the priority, because it is your team.	You file a ticket and wait with everyone else.
Leaving	The code and the data are yours.	Export what the vendor lets you export.

04 Common questions

Common questions

What have you actually built in this space?

Dev13 Systems is the clearest example: an AI-native agency operating system with twenty-five specialist agents working over organisation-scoped retrieval. XBuilder is the same engineering pointed at a different domain — a document-intelligence pipeline that turns PDF construction drawings into structured, confidence-scored quantities an estimator can bid from. Both are publicly reachable — click through and judge the engineering yourself.

Do you build AI agent systems?

Yes, and the hard part is never the model — it is retrieval scope, evaluation, and cost control. We build those first, because an agent you cannot evaluate is an agent you cannot ship.
