E-Commerce Development
in London
Storefronts that convert and checkouts that don't break at scale.
We build e-commerce storefronts for founders in London — headless Shopify Hydrogen when you need custom UX, a hardened Shopify Plus theme when speed matters more, custom carts when the platform gets in the way. One senior engineer owns checkout, inventory sync, and the storefront, so launch day isn't held together by three unrelated apps.

How this works
One AI-native engineer.
The output of a team.
One senior engineer plus AI agents now ships e-commerce development that used to need a four-person team. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in London who need to ship before the next round closes.
The local read
Why e-commerce development is hard in London
London founders have access to deep fintech and gov-tech talent but the hiring cycle is brutal. Senior offers in the City clear £100K base plus equity that competes with Revolut and Wise. Local dev shops mostly serve enterprise — slow procurement, multi-quarter contracts, agency-of-record billing.
Different model: one senior engineer ships your build in two weeks, four-to-five-hour overlap with our working hours, billed in USD. Open Banking via TrueLayer or GoCardless for fintech. Next.js + NestJS + Postgres for SaaS. Flat-price quote in 24 hours. Code in your GitHub from commit one.
London's accelerator bench includes Seedcamp (since 2007, early backer of Revolut, Wise and UiPath), Techstars London and Entrepreneur First, which matches and funds co-founders before they've even formed a company. Early checks come from Passion Capital (Monzo, GoCardless, Tide) and Stride VC, which raised a $138.6M second fund. The fintech concentration is the real story: London is home to 2,500+ fintech companies and captured 79-90% of all UK fintech funding in 2025 out of roughly £2.6B invested nationally. That density comes at a cost for founders — the median advertised software engineer salary in London sits at £115K, and the UK's 2025 immigration reform raised the Skilled Worker visa threshold to degree-level roles with a £41,700 salary floor, tightening the pipeline further. 95% of UK engineering employers now report talent shortages.
London's AI funding hit a record in 2025: London-based AI companies raised £5.73B across 682 rounds, inside a UK-wide £8.3B AI investment total — roughly three times what was raised in 2024. The office real estate is following the capital: OpenAI announced its first permanent London office in April 2026, an 88,500-sq-ft space at King's Cross opening in 2027 with room for 544 staff, more than double its current London headcount, while Google's million-square-foot King's Cross tower is built for up to 7,000 people. On the funding side, LocalGlobe, deploying 80% of its capital in the UK since 1999, has backed 17 unicorns and 5 IPOs, and Balderton Capital raised $1.3B combined across two funds in 2025 alone. That's an enormous amount of capital and corporate gravity landing in a few square miles — and every one of those companies is hiring against the same senior engineer you need.
Most of the e-commerce development briefs we get out of London trace back to its Fintech and AI base — that's the local demand, not a guess.
Hiring one senior engineer here is a ~$200K year-one outlay and a 60–90 day search. Our e-commerce development engagement starts at $3,000 with a first deploy in 2–3 weeks.
