What ONMAIN LIMITED does
ONMAIN LIMITED is a UK-based private technology company founded in May 2023 by Andrei Crut, operating from London with its registered entity in England & Wales. The company is structured as a parent brand with two operational divisions: Onmain Systems, a custom web development service that builds bespoke websites, web applications, and business platforms using Next.js, TypeScript, React, and GSAP, and MainSearch AI, an AI-powered marketplace platform connecting UK consumers with verified local service businesses (IT repair, plumbing, electrical) through conversational AI, instant price estimates, and automated quote collection. The technology stack includes integrations with Stripe (payments), Google OAuth (authentication), Microsoft Clarity and Vercel Analytics (analytics), and third-party LLMs from OpenAI or Anthropic for the AI chat interface.
The business model combines one-time project fees for web development (packages priced £165-£900+ with split-payment options) with a tiered subscription offering for MainSearch AI (Free, Basic, Pro, Business), plus pay-per-job IT maintenance and hardware repair services. Go-to-market is hybrid: sales-led for Onmain Systems (direct website, phone, email with 30-minute reply guarantee) and product-led for MainSearch AI (self-serve platform with freemium onboarding). The customer base skews toward UK small and medium businesses for web services and UK consumers for service matching, with 50+ satisfied clients, 67 completed projects, and 103 Google reviews at 5.0/5 stars as reported scale metrics. The company is bootstrapped with no disclosed external funding, registered with the UK Information Commissioner's Office (ICO ZC127665), and aims to meet WCAG 2.1 AA accessibility standards.

ONMAIN LIMITED competitors and assessment
Company assessmentDirect peers
- TrustATrader: UK directory of vetted tradespeople with consumer review features. Closely comparable to MainSearch AI's credential verification, review display, and multi-business comparison positioning.
- Bark: Global services marketplace where consumers post needs and professionals respond with quotes. Highly comparable to MainSearch AI's conversational intake plus multi-business quote collection.
- Checkatrade: UK's largest consumer-facing marketplace for vetted tradespeople (plumbers, electricians, IT repair). Most directly comparable to MainSearch AI's verified-business directory and consumer-to-trades matching flow.
- Rated People: UK home services marketplace matching consumers with local tradespeople via posted jobs. Overlaps directly with MainSearch AI's quote-forwarding and local business recommendation model.
Broad incumbents
- Squarespace: Template website builder with subscription pricing aimed at SMBs and creators. Competes for the same Onmain Systems buyer profile, with opposite trade-off (template ease vs custom ownership).
- Webflow: Visual web development platform enabling professional website creation without code. Adjacent to Onmain Systems' custom-coded offering but targets a different (template/no-code) buyer profile.
- Wix: Leading template-based website builder explicitly named by Onmain as the incumbent pain point ('Zero Wix setup'). Competes for the same UK SMB website-build budget but with subscription economics.
- Geek Squad: Best Buy's device diagnostics, repair, and IT support service. Direct overlap with Onmain's IT maintenance and hardware repair revenue stream and the IT repair listings seeded into MainSearch AI.
Regional players
- Hipages: Australian home services marketplace connecting consumers with tradies. Comparable business model to MainSearch AI but geographically separate; useful as a regional comp for marketplace unit economics.
Emerging players
- Thumbtack: US services marketplace using AI-powered matching between consumers and local professionals. Conceptually analogous to MainSearch AI's NLP-driven recommendation engine, but operates at much larger scale in the US.
