Building products that help people think, work, and play.
We design and build human-first AI products that treat the human side as seriously as the technical side. Interfaces that feel conversational and forgiving, systems that explain their reasoning, and technology that fits into how people actually work rather than forcing them to adapt.
Mass
Human insight, reimagined through synthetic minds. A platform that allows you to create synthetic human personas that can think, reason, and respond like real people.
Emmly
Make space for what you imagine. Creative partner that unlocks new ways of thinking, feeling, and making. Emmly empower creators to explore, experiment, and create without limits.
Beryl
E-commerce website for Beryl, a London-based bike light and transport company. Today, they support over 300,000 people using their bikes, e-bikes, e-scooters and cargo bikes to get to work university, and to explore.
Appo
Appo was a startup that built a chatbot for businesses to help them automate customer support and sales for dental practices using AI and chatbots.
AI products built at startup speed, without the agency friction.
Built for AI products
We work with product, data, and engineering teams to ship production AI systems - conversational interfaces, copilots, multi-agent workflows - that teams actually rely on.
Systems > Services
No hand-offs. No queues. Just proven product engineering refined across decades of shipping complex systems for global brands.
Deliver exactly what you need
From RAG integrations to agentic workflows, everything is built with monitoring, guardrails, and proper error handling. Production systems, not prototypes.
Built for founders who need things done right.
RAG & Retrieval
Production-ready retrieval systems for AI products that need to move fast and actually work. Data pipelines, chunking strategies, citation handling, and evaluation harnesses.
Agentic workflows
Multi-agent systems that do boring work end to end. n8n integrations, MCP servers, and human-in-the-loop approvals that help complex AI products feel simple and reliable.
Copilot development
Go from idea to production copilot in weeks. Perfect for AI tools launching internal assistants, customer-facing agents, or task-specific helpers.
Production hardening
We act as your AI engineering team - shipping guardrails, monitoring, evaluation frameworks, and safety checks without slowing you down.
Evaluation & Quality
Testing frameworks and regression suites built for startups who need Series-B reliability on a Seed-stage budget.
UK-based, UK suppliers.
Data sovereignty
We work exclusively with UK-based suppliers, or suppliers in the same country as our clients. This means your data stays within the right legal jurisdiction, GDPR compliance is straightforward, and there are no cross-border data transfer complications.
Time zone alignment
Same time zone means faster responses, easier collaboration, and support when you actually need it. No waiting for someone to wake up on the other side of the world.
Legal & regulatory alignment
UK suppliers understand UK business law, contract terms, IP protection, and regulatory requirements. Contracts are simpler, disputes are clearer, and everyone knows the rules.
