Custom LLM applications, RAG systems, AI automation and fine-tuning for United Kingdom businesses. Fixed-fee scoping, shipped to production, and you work directly with the engineer who writes the code.

Every engagement starts with a free discovery call and a fixed-fee proposal — scope, deliverables, timeline and price agreed before any work starts. No hourly billing. Every engagement is scoped in a free consultation before anything is quoted. You receive a written fixed-fee quotation covering scope, deliverables and timeline — no hourly billing, no open-ended retainer, and no number until we understand the work.
Scoped before it is built. Every engagement opens with a free discovery call, then a written proposal: scope, deliverables, timeline and a fixed fee. No hourly billing and no open-ended discovery. If a project should not be built, we say so at that stage rather than after the budget is spent.
Production, not proof-of-concept. UK procurement tends to shortlist from search and then verify with independent sources, so visibility has to survive a second look. The deliverable is a system running in your environment with monitoring, cost controls and documentation — plus 30 days of post-launch support on every build.
Visibility included. The UK market rewards demonstrable expertise over volume: British buyers check credentials, case detail and scope clarity before they enquire. Where it matters, AI builds pair with United Kingdom SEO and United Kingdom GEO so the product and the demand arrive together. See how we work and the live systems already shipped.
Custom LLM application development, RAG knowledge systems, AI workflow automation, model fine-tuning (SFT, DPO, LoRA, QLoRA), AI strategy audits and production engineering — delivered for United Kingdom businesses on a fixed-fee basis.
Every engagement is scoped in a free consultation before anything is quoted. You receive a written fixed-fee quotation covering scope, deliverables and timeline — no hourly billing, no open-ended retainer, and no number until we understand the work. A discovery sprint is typically one to two weeks and produces the architecture and roadmap; a build runs four to twelve weeks depending on scope. Price is agreed in writing before work starts.
Yes. Modulus is remote-first and works across GMT/BST (UK business-hours overlap). United Kingdom clients get scheduled calls in local business hours and direct access to the engineer building the system — there is no account-manager layer.
Both, chosen per workload. Frontier APIs where quality and speed of delivery dominate; open models where cost, latency, data residency or control dominate. The trade-off is documented in the proposal rather than decided by default.
Every build includes 30 days of post-launch support, documentation and handover. Ongoing support, iteration and roadmap work are available as a retained engagement if you want it — not required.
Dam — founder and lead engineer. When you hire Modulus you work directly with the person writing the code. That is the reason scoping is fast and the reason the studio takes a limited number of engagements at a time.
Operators with a real workflow problem — repetitive judgement work, document processing, support triage, internal search — where a well-scoped system pays back inside a year.
Product teams adding AI features that need the retrieval, evaluation and cost engineering done properly rather than a demo wired to an API key.
Leadership teams needing a decision before committing budget: what to build, what to buy, what to skip, and what it will actually cost to run.
UK engagements tend to start with a documented process that is expensive to run manually and painful to get wrong — which is exactly where scoped AI pays back.
