We ship Silver Bullets your marketing team wishes they had.

An AI-native build studio. We turn the tools your team keeps asking for into live products — in days, not quarters.

// Our own silver bullet

A working demo of what we ship.

In 2014, our Scientific Lead defended his PhD at Åbo Akademi University on capturing tacit expert knowledge with fuzzy ontologies. The academic test domain was wine recommendation. We just rebuilt it — 3,000 wines from Alko's public catalog, fuzzy attributes extracted by Claude, sommelier-style explanations on top — in three days. The math is the same as the thesis. The source code is public.

Tell it what you're eating tonight. Watch the membership values.

// Services

Two service lines. One outcome: live.

Decide what to build. Then build the silver bullet. Most engagements involve both — and ship in days, not quarters.

01 / Build

AI-Built Tools, Shipped Fast

The calculator your sales team has been asking for. The portal finance can't get IT to prioritise. The agent ops has been faking in spreadsheets. Fixed scope, fixed price, live in days — starting from €2,000 + VAT, depending on the complexity of the bullet.

→Customer extranets & portals
→Predictive analytics
→AI agents & chat
→Landing & campaign sites
→InfoTV & digital signage
→Internal tools & calculators

02 / Advisory

Concepts & Advisory

Before you build, decide what's worth building. We help you pick the right problems and the right silver bullets to fire — grounded in your data and PhD-level decision science.

→Opportunity mapping & problem framing
→Data audits & funnel diagnostics
→Concept sprints & solution shaping
→Prioritisation & roadmap design
→AI decision frameworks
→Build-vs-buy advisory

// What we don't do

Some things we will never sell you.

Differentiation is half about what you refuse. Here's what we don't do.

No AI training workshops.

We build the thing — not run a 3-day prompt course.

No strategy decks without code.

Every engagement ends with something live.

No AI-vendor lock-in.

Outcome-obsessed, not tool-loyal.

No hourly billing on builds.

Fixed scope, fixed price, fixed deadline.

// Process

From brief to live app in one week (or less).

Agencies sell quarters. We sell weeks. A typical fast-track build:

Day 1 · Frame

Brief & scope

Problem, user, success metric, smallest valuable thing to ship.

Day 2–3 · Build

First version live

A working v1 on a real URL — not a Figma file.

Day 4 · Refine

Test & iterate

Real users. Measurement instrumented from commit one.

Day 5 · Ship

Production-ready

Polish, integrations, analytics. You walk away with an asset.
