SERVICES
# Four things we take on. Everything else, we'll politely send elsewhere.

We're a senior-only studio of three. Specialism beats breadth at our size — and it means we can quote you on a Tuesday and start on a Wednesday.
01STRATEGY
## AI strategy

We turn AI ambitions into a costed, dated plan you can argue with. Discovery, opportunity mapping, build-vs-buy, an honest roadmap — and a written spec you can take to your board or to your engineers without translation.
**For:** Founders, product leaders, eng directors·**When:** Pre-build · pre-RFP · pre-deck
#### What's included

- 1–2 week discovery with you and a sample of your users
- Opportunity map: what's worth doing, what isn't, why
- Build vs. buy vs. wait — recommended path with cost ranges
- Eval framework: how you'll know it's working
- Risk register and known-unknowns — written down
- A spec your engineering team can implement, or that we can

02IMPLEMENTATION
## AI implementation

The unglamorous middle that turns demos into products. Model selection, retrieval, evaluation, ops, integration with the systems you already have. Bring your own keys; we don't mark up tokens.
**For:** Teams with a spec and a deadline·**When:** You've scoped it · now ship it
#### What's included

- Model selection across Claude, GPT, Gemini, open-source — with the reasoning written down
- Retrieval design (chunking, embeddings, hybrid search) tuned to your domain
- Eval harness with golden sets — so regressions don't slip past code review
- Prompt + context engineering, not prompt 'engineering'
- Production observability: traces, costs, error budgets
- Hand-over docs the next engineer can actually read

03PRODUCT
## Product strategy

Sometimes the hardest part isn't the AI — it's deciding what to build at all. We do discovery, scoping, prioritisation, and write the spec. Short, sharp engagements. Outcomes-not-decks.
**For:** Pre-MVP teams · post-pivot teams · stuck teams·**When:** Before you brief an agency or hire a build team
#### What's included

- User research with a small, real sample — not personas
- Job-to-be-done framing and one-page product narrative
- Scope: must-have, should-have, won't-touch
- Tech feasibility check — so you don't sell a product you can't ship
- A spec doc the team will actually open more than once

04DELIVERY
## Full-cycle product delivery

Design through engineering through launch. Mobile-first (Android/Kotlin is our deepest stack), web, backend. We assemble a small squad, ship in milestones, and hand it back cleanly when you're ready to take over.
**For:** Companies who'd rather have shipping software than a roadmap·**When:** 8–24 weeks · milestone fees · clean handover
#### What's included

- Product design + UX, integrated with engineering from week one
- Android (Kotlin/Compose), iOS (Swift) when needed, web (TS/Next.js)
- Backend: JVM (Kotlin/Java), Python, Postgres, the boring resilient stack
- AI features integrated as features, not flagship novelties
- CI, infra, observability — we leave behind a healthy system, not a black box
- Handover that includes onboarding the next team

OUR STACK
We're honest about what we use. If your stack isn't on here, we're probably the wrong shop.
