London remains Europe's default HQ for venture-backed SaaS, challenger banks, and media tech — with salaries and office costs that push even well-funded teams toward distributed engineering. Hiring senior Next.js or platform engineers competes with finance and big tech counteroffers. GDPR-aware delivery is table stakes; US-shop vendors often underestimate UK privacy expectations and procurement rigor. Product leaders want partners who document data processing, ship in staging first, and join afternoon GMT calls without forcing midnight India schedules on their side. Jythu works with London teams on SaaS rebuilds, Shopify international storefronts, and AI features with retrieval and audit trails — remote-first, with BST-friendly overlap.
Jythu wires large language models into products you already run — RAG over your docs and databases, tool-calling agents with guardrails, eval harnesses, and cost controls finance can read. Not a chat widget stapled on a homepage. We integrate OpenAI, Anthropic, or open weights behind your VPC with citations, rate limits, and observability baked in. For London teams, that usually means fewer contractor handoffs and a partner who will cut scope when the calendar is real.
United Kingdom capital — fintech, media, and B2B SaaS on GMT/BST. We tailor AI & LLM integration around local collaboration habits — local proof section, city case study/testimonial, timezone/response-time note.

Built for this market — not a generic offshore brief
Why teams in London hire Jythu
GMT/BST afternoon overlap — reviews and demos fit the London workday; async handoffs respect UK holidays, GDPR expectations, and the reality that your counsel leads on lawful basis.
Senior builders, written scope
Two-week sprints, staging on every PR, and deliverables your team can own — not a black-box ticket queue.
GDPR-aware delivery
Hosting, subprocessors, and data handling planned for GDPR / UK GDPR review paths — your counsel owns legal sign-off; we implement the technical controls you specify.
In-product assistant (NDA)
Support volume and docs sprawl pushed a product team to put answers inside the app. Answers had to cite sources, never hallucinate pricing, and stay under a weekly cost cap.
Result: Hybrid RAG over CMS and product DB with tool calls for account actions behind confirmation. Material share of tier-1 tickets deflected; cost per 1k queries became predictable after caching.

Questions teams ask before kicking off
Do you work UK hours for London clients?
Core meetings land afternoon GMT/BST — typically three to six hours overlap with India, enough for pairing and decisions same day.
How do you approach GDPR for UK builds?
We implement to your privacy policy and DPA requirements — lawful basis, retention, and subprocessors are your legal team's call; we build auditable data flows.
Is pricing in GBP or USD?
Quotes are usually in USD with clear payment terms; invoicing details are settled in contract. No hidden FX markups on scope.
How do you keep AI answers grounded in our data?
We start with a discovery call, then a written in/out list for AI & LLM integration. Estimates follow constraints — timeline, stack, and who owns the repo — not a one-size quote calculator.
