Old.St Labs

What Old.St Labs does

Old.St Labs is a London-headquartered, AI-native software development consultancy founded in April 2020 by Rob Lynch and Rob Woodhead. The firm designs and builds bespoke digital products — mobile apps, web applications, AI-driven automation, and digital transformation programmes — primarily for SMEs and ambitious early-stage companies across healthcare, education, fintech, sports, music, community, restaurant, fitness, property, and electric-vehicle sectors. Its flagship offering is a four-stage engagement process (Definition, Design, Development, Partnership), supplemented by a recently productised Vibe Code Audit service (Single Focus at £500, Complete at £1,000) that reviews AI-built products across security, scalability, and code quality. Customers include Impiricus (US pharma-text platform), Mariana UFP (financial-services compliance), Pixel Artworks (large-format display dashboards), Pickr (music-industry marketplace), Brainie (AI math tutoring), CityMunch (restaurant deals), VEV (fleet electrification), and Autistica's Molehill Mountain anxiety app.

The company operates a technology-agnostic delivery model that incorporates AI into nearly every project, leveraging models from OpenAI, Anthropic, Google, and open-source providers for LLM features (chat, summarisation, classification, document understanding) and agentic workflows that act on users' behalf. Proprietary internal tooling includes an AI-accelerated development stack, an LLM Connector Layer for multi-model orchestration, a Session Orchestration Engine for adaptive learning, a curriculum-aware content management system, and a custom client portal. Headquarters and senior consulting staff are based at 13 Devonshire Gardens, London W4 3TN, with engineering delivery teams in the Philippines and Cape Town providing full overlap with UK working hours. Old.St Labs has achieved UK Cyber Essentials certification, holds a 5.0 Clutch rating, and has been recognised across multiple Clutch rankings from 2022 through 2026 and featured in The Daily Telegraph's New Year Business Guide 2026.

The business model centres on professional services engagement revenue. Project fees span from approximately £10,000 for focused builds to £100,000+ for multi-phase programmes, quoted as fixed-price or hourly; a "Partnership" phase after launch converts completed projects into ongoing retainer relationships, several of which are 4–5+ years long. Distribution is direct and sales-led, with both founders involved in every engagement and demand generated through inbound discovery calls, case-study content, and the Old Street Labs podcast. The legal entity is Old St Ventures Limited (registered in England and Wales, company number 12693846); there is no disclosed outside institutional investment and the firm appears bootstrapped and founder-controlled. Pricing for the Vibe Code Audit (£500–£1,000) is publicly disclosed, while project pricing is engagement-specific.
