The companies we build for

Find the one that fits where you are right now.

Early-stage startup

You have a product idea and some funding, but no engineering team. You've probably tried a freelancer or two and it didn't go well. You need someone to build the first version of your product and take ownership of making it happen.

Best fit:

Founder or CEO, pre-seed to Series A

Talk to us about your product

You'll recognise yourself if

Contractors disappear or deliver something that can't be maintained or built on.

You're spending months in development without anything to show investors.

You don't have the technical background to evaluate what's being built or what it should cost.

Every delay costs you runway you can't get back.

How we help

We take full responsibility for the build - architecture, development, testing, and delivery. You get a working product on a fixed price and timeline, with full IP ownership from day one.

Growing tech company

You have an engineering team but it's not big enough to hit your roadmap. Hiring is slow, local senior talent is scarce, and you can't afford to slow down. You need engineers who work the way your team works - not a separate agency running its own process.

Best fit:

CTO or VP Engineering, Series B and beyond

Talk to us about your team

You'll recognise yourself if

Approved headcount you can't fill fast enough through normal hiring.

Specific technical skills - AI/ML, DevOps, platform engineering - that your current team doesn't have.

External teams that don't integrate - different tooling, different standards, code reviews that go nowhere.

Roadmap commitments to the board that your current capacity can't meet.

How we help

We provide senior engineers who integrate directly into your team - your tools, your codebase, your sprint process. They work alongside your engineers and are held to the same standards.

Enterprise

You're a an organisation with existing systems, internal processes, and procurement requirements. You need an external partner who can operate within those constraints - delivering quality software without disrupting what's already working.

Best fit:

IT Director, Head of Engineering, or Transformation Lead

Talk to us about your project

You'll recognise yourself if

Legacy systems that are expensive to maintain and difficult to integrate with modern tooling.

Internal teams stretched across day-to-day work with no capacity for new development.

Large vendors who require long onboarding cycles before anything gets built.

Governance, security, and compliance requirements that most smaller agencies can't meet.

How we help

We work within your existing governance and security framework, integrate with your internal teams, and deliver to agreed milestones with full documentation and handoff.

Non-tech business

You run a business that isn't a software company, but you have operations, workflows, or compliance processes that requires custom software. Off-the-shelf tools don't quite fit, and you don't have an internal engineering team to build what you need.

Best fit:

COO, Head of Ops, or IT Director, fintech, healthcare, logistics

Talk to us about your project

You'll recognise yourself if

Core business processes running on spreadsheets and manual steps that don't scale.

SaaS products that cover most of your workflow but not the specific part that matters most to your business.

Compliance and audit requirements that generic tools can't meet.

No internal team to manage a long-term vendor relationship.

How we help

We design and build the tool your business needs, handle the compliance and data requirements upfront, and hand it over fully documented. Your team owns the delivery with no dependency on us unless you choose otherwise.

AI tooling across every stage of the build

We use AI tools throughout the build process - not just for product features, but for how we write code, run tests, and ship faster.

Icon
AI-accelerated engineering
Our engineers use Cursor, GitHub Copilot, and Claude as part of their daily workflow. Less time on boilerplate, more time on the problems that actually matter.
Icon
LLM feature integration
Document processing, search, classification, chat interfaces - we've built these into production products and know where the complexity actually sits.
Icon
AI-assisted
QA
Test coverage is written and maintained with AI tooling. Edge cases get caught earlier and regression tests run on every push.
Icon
RAG & knowledge pipelines
We build retrieval-augmented generation systems that let your product reason over your own data - documents, databases, or internal knowledge bases.
Icon
Workflow automation with AI agents
We identify manual steps in your operations that AI can handle - data extraction, routing, drafting, classification - and build those automations into your product or internal tools.
Icon
AI-powered analytics & insights
We turn raw product and business data into actionable insights using AI - dashboards, anomaly detection, and predictive models that help you make faster decisions.

What makes us different to work with

Icon
One team,
end-to-end
A dedicated squad - PM, tech lead, engineers, and QA - working on your project together. One point of contact, full accountability.
Icon
Fixed milestones, not hourly billing
You agree on scope and price upfront. Payments are tied to delivery milestones, so there are no unexpected invoices.
Icon
You see working software early
We get something in front of you as soon as possible - not at the end of a long build cycle. That way problems surface early, not late.
Icon
You own everything we build
Full IP transfer on delivery. The codebase, documentation, and all assets are yours - no licensing, no lock-in.
Icon
Senior engineers on every project
We don't staff projects with juniors. Every team is built around experienced engineers from our tech hub in Europe, led by a dedicated tech lead.
Icon
European timezone coverage
Our team overlaps with UK, DACH, and Israel working hours. Regular standups, weekly demos, and direct access throughout the project.

Five ways to engage

Discovery call

We learn about your business, what you need to build, and what's already in place. By the end of the call you'll have a clear sense of how we'd approach it and whether we're the right team.

Scoped discovery

Our tech lead and PM define the architecture, user flows, and delivery plan. You receive a detailed spec and a fixed quote before any development begins.

Working prototype

Before the build goes deep, you have a functional version to review. Decisions get made early, when they're still straightforward to act on.

Sprints with weekly demos

You see a demo every week and can adjust priorities between sprints. Progress is visible throughout — there are no long gaps between updates.

QA, staging and go-live

We run a full test cycle on a staging environment before release. You review and approve before anything is deployed to production.

Handoff and knowledge transfer

You receive the full codebase, technical documentation, and a recorded walkthrough. We run a live session with your team to make sure they can maintain and extend what we've built.
