Straight answers, no hedging.
What we build with AI, how we work, and who owns the result. If your question isn't here, bring it to the call.
What we build
What does Stacklane actually build?
AI solutions that run in production: agents and assistants, workflow automation, custom AI platforms, and the integrations that connect them to your stack. We build the whole thing end to end, software, design, and brand, not just a model in a notebook.
What does “AI-native” mean here?
AI is in how we build, not a feature we bolt on. We use it across generation, review, testing, and observation, and we build products with AI at the core: RAG, agents, evals, guardrails. Fast because AI is in the loop, real because senior judgment is on every change.
Is the AI real, or a demo?
Real. We ship agents, RAG pipelines, and evals to production and maintain them. The proof is our own products, Moneyline and SpotMe, running with real users, not a slide.
When is custom AI worth it over an off-the-shelf tool?
When the generic tool doesn't fit: you have specific data, your own business logic, or you want AI embedded in an existing product or process. If a SaaS covers it, we'll say so. Custom only earns its place when it does something the shelf can't.
How we work
How do we work together?
One team on your work, week by week. You see progress in your own repo and a demo on a fixed slot. Priorities can change on Monday, without change orders or scope renegotiation.
Which technologies do you use?
We choose per use case, from classic models to LLMs. Typically TypeScript and Python, modern web stacks, the major model providers, vector search, and eval tooling. What delivers most, not the newest thing for its own sake.
Do you work with our internal IT or dev team?
Yes. We plug into your team, tools, and workflows rather than around them. We can lead, pair, or hand off cleanly, whatever fits how your team works.
What happens after we go live?
An AI solution is never done. We measure against real cases, monitor it, and keep developing it based on how you actually use it. You keep everything, so you can also take it in-house whenever you want.
Ownership, data, and fit
Who owns the code?
You, from day one. The code, the prompts, and the eval sets live in your own environment, on your accounts. No lock-in, no black box: you can read, change, and keep everything we build.
How do you handle data, security, and the EU?
We build under Dutch law with a clear data-processing agreement, and we keep data in the EU. Guardrails, access controls, and audit trails are part of the build, not an afterthought.
When is Stacklane the wrong fit?
When you want the cheapest possible hands, a one-off script with no ownership, or AI theatre for a pitch deck. We build real software you keep and maintain. If that's not what you need, we'll tell you on the call.
How do we get started?
A 30-minute call. We figure out what you need, whether AI is the right tool, and whether we're the right party to build it. No pitch deck, and an honest answer either way.
Still have a question?
Bring it to the call. We give a straight answer on fit in 30 minutes, no pitch deck.
