Understand first. Build fast. Scale together.

Understand first. Build fast. Scale together.

We embed in your team before we build anything. Fixed price, weekly demos, and a product that fits like you built it yourself. Except you didn't have to.

Three phases. One production system.

01
3 days
Prove it

Before building the full solution, we create a proof of concept for your business. In two focused days with your team, we map your operations, decision flows, data landscape, and compliance requirements, as they actually work. The result is a working concept that proves whether the solution delivers real value.

Build it

One of our engineers joins your team in your daily workflow, your communication channels and your rhythm. Every week you'll have a working demo. Not a slide deck but functional software you can see, test, and challenge.

Run it

Your system is live. Conditions change, edge cases surface, performance needs tuning. Continuous monitoring, automated alerts, and direct access to our agentic workforce and dedicated engineer.

Monitoring

The closer the engineer, the better the system.

There's a reason we embed. Not because it's a nice model, but because it produces fundamentally better outcomes.

Traditional developers build from briefings. Someone inside your team builds with understanding. They see why the exception exists in your business. They hear the workaround no one documented. First-hand, not through a middleman.

Miss those, and you build a system people work around instead of with. It's why we embed. And why our systems actually fit.

What you're probably thinking.

What's the difference between this and hiring an agency?

An agency bills by the hour and starts from scratch every time. We start from a proven product and customize the last 20% to your business. Fixed price. Faster delivery. And after launch, you get ongoing support and not an invoice with a goodbye.

How is this different from buying off-the-shelf SaaS?

Generic SaaS forces you to adapt your business to the software. We adapt the software to your business. Same modular foundation, but the intelligence layer, integrations, and interface are configured to how you actually work. The result feels like a custom product at a fraction of the cost.

What does 'embedded engineer' actually mean?

During the Build phase, our engineer embeds directly with your team. They join you in the office and learn your domain and operations. This isn't remote consulting but someone inside your operation building the right thing. After Build, the system runs on our platform and we maintain it remotely.

What does '24/7 agentic support' mean?

During Run, you get a dedicated channel. Our AI agent monitors your system, catches issues, and handles routine support automatically. When something needs a human, an embedded engineer reviews it directly. Not a ticket that waits on a sprint backlog for 4 weeks. It's the same philosophy as the intake: AI handles the routine so our people can focus on what matters.

Can we use the products to serve our clients?

Yes. That's what the white-label option is for. We build the platform, you put your name on it. Your clients see your brand, your pricing, your login screen. Stackhavn stays invisible. We handle the tech, the updates, and the compliance. Licensing terms are part of our general terms.

Do we own the product?

Part of it. You subscribe to our platform like any SaaS product. Stackhavn retains IP ownership of the platform modules. You own your data, your customization including company logic. You can export all your data at any time. Your own customization without a maintenance burden. We keep improving it for you.

What if we want to leave?

Your data is yours. Full export of all data, configurations, and documentation. The stackhavn platform modules stay with us. We design for clean exits because we'd rather earn your stay every month.

What's EU-sovereign infrastructure?

Your data stays in Europe on European cloud providers. Not AWS, not Azure, not GCP. GDPR, EU AI Act, and data sovereignty compliance by default. Not as an afterthought.

How can a small team handle multiple clients?

Our agentic workforce. AI agents handle code generation, testing, debugging, and monitoring which normally eats engineering time. That frees our engineers to spend 100% of their time with you, understanding your business. We scale through intelligence, not headcount.
