Custom AI software,
end to end.
Take a real problem, design the system, build it, deploy it on infrastructure you can own, hand it over. Generalists in AI application engineering — with one promise: speed without cutting corners on correctness.
AI applications over your data.
Grounded answers from your own documents, records and operational data — with citations, high recall, and behaviour you can audit.
RAG over your data
Grounded answers with citations — not hallucinations. Your documents become a source you can interrogate in plain language.
Hybrid search
Vector embeddings fused with keyword/full-text search for high recall in any language — with strong multilingual handling, including Finnish.
Agentic tool-use
LLM agents calling typed, safe tools — SQL templates, search, lookups — to assemble correct, auditable answers.
Chat-over-your-data
Streaming chat interfaces that let non-technical users question a whole corpus, with history and feedback built in.
Ingestion & crawling
Automated, self-healing pipelines that keep a corpus current and observable — even from messy public sources.
Programmatic data APIs
Turn a messy public or private source into a clean, billable JSON API with scoped keys and usage metering.
Test before you invest — in four moves.
Frame the problem
We start from a real problem, not a feature list. What decision are you trying to de-risk? What would a convincing result look like? No long discovery-theatre phase.
Build the MVP
A working product — designed, built and deployed on infrastructure you can own. On the order of a month, not a year. Speed without cutting corners on correctness.
Put it in front of users
Real, usable software in the hands of real users. You learn which ideas actually have opportunity — with evidence, not opinion.
Own it, then scale
All code, data and operations are yours from day one. When an idea proves itself, take it to an internal team or a bigger partner to scale. We're an accelerator, not a lock-in.
The second system of its kind costs a fraction of the first.
The hard parts are already built and battle-tested in production. We adapt them to your domain and data instead of starting from zero.
Self-healing crawl & ingest pipelines for messy public or private sources
Hybrid vector + keyword retrieval over any corpus, in any language
Agentic, tool-using chat backends with grounded citations and safe data access
Streaming bilingual chat UIs with auth, history and feedback
Billing-gated data APIs — token balances, scoped keys, usage ledger
Self-hosted, GDPR-friendly deployment on EU infrastructure you own
Proven on real projects. Chosen per project.
Self-hosted where it makes sense for cost, data residency and GDPR; managed cloud where it's faster. Either way, the client can take the whole thing over.
Four ways to work together.
Build / validation projects
Fixed-fee MVP builds — the core sisu + MVP offering.
Software licensing
Perpetual source-code licences for finished products.
Managed operation & pilots
Optionally run a product for a fixed period — hosting + AI costs — before handover.
Consulting & training
Expert services around AI applications, retrieval and data engineering.
