LLM features that actually ship to users.
We ship AI features for founders in London — chat interfaces, RAG over your data, agents that do work, evaluations that tell you when the model is broken. Production-ready LLM apps, not demos. We use Vercel AI SDK, AI Gateway for model routing, and the eval tools that work in 2026.

How this works
One AI-native engineer.
The output of a team.
One senior engineer plus AI agents now ships ai product development that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in London who need to ship before the next round closes.
The local read
Why ai product development is hard in London
London founders have access to deep fintech and gov-tech talent but the hiring cycle is brutal. Senior offers in the City clear £100K base plus equity that competes with Revolut and Wise. Local dev shops mostly serve enterprise — slow procurement, multi-quarter contracts, agency-of-record billing.
Different model: one senior engineer ships your build in two weeks, four-to-five-hour overlap with our working hours, billed in USD. Open Banking via TrueLayer or GoCardless for fintech. Next.js + NestJS + Postgres for SaaS. Flat-price quote in 24 hours. Code in your GitHub from commit one.
Hiring one senior engineer here is a ~$200K year-one outlay and a 60–90 day search. Our ai product development engagement starts at $8,000 with a first deploy in 2–5 weeks.

What you actually get
Concrete deliverables.
Live in 2–5 weeks.
No discovery phase that bills for itself. No Figma-only delivery. Every item below is something you can open, click, and ship to a user.
Streaming chat or agent UI with proper UX (interrupt, retry, citations)
RAG pipeline over your data — chunking, embeddings, hybrid search, citations
Provider routing via Vercel AI Gateway — Anthropic primary, OpenAI/Gemini fallback
Evals: a real test set, a deterministic CI check that catches model regressions
Observability: tool-call traces, token spend, latency per provider
Why us
Why founders in London pick us for this
01
We ship LLM features weekly — eval-first workflow, not 'ship and hope'
02
Model-routing day one so you're not locked to one provider's pricing or outages
03
RAG done with hybrid search + reranking, not naive embedding cosine similarity
04
Cost-aware: caching, model tiering (Haiku/Sonnet/Opus), budget alerts wired in
