Custom software
& web apps in London.

Custom web platforms, mobile apps, and SaaS for London agencies and operators — senior engineers, fixed-scope discovery, weekly staging demos. Between a local boutique that cannot staff depth and a US giant with awkward overlap, WLS gives you an English-first delivery partner with working-day UK hours and milestone commercials you can put in front of finance.

Why London teams choose WLS

Built for agencies
that ship under pressure.

/ 01UK-ready commercialsStatements of work, change control, and milestone invoicing written the way London finance and agency ops already buy — GBP-friendly when you need it, with acceptance criteria before the build starts.
/ 02UK working-day overlapLive sessions land inside London office hours; decisions are written the same day so UK stakeholders are not stuck waiting on a distant timezone for unblockers.
/ 03GDPR-aware delivery postureEU/UK data expectations are treated as delivery constraints — access boundaries, environment hygiene, and vendor handling discussed early, not bolted on after UAT.
/ 04Invisible when you need white-labelNDAs, branded artefacts, and client-facing silence when you are the agency of record — your relationship with the end client stays yours.
How London programmes run

An operating cadence
you can plan around.

01
STEP 01 · KICKOFF · Day 1

Kickoff that lands in writing

Goals, constraints, and risks in one working session — then a written summary, decision log, and proposed cadence the same day.

02
STEP 02 · BUILD · Weekly

Progress you can inspect

Staging releases with demo notes — working software, not narrative decks. Slack or Teams for day-to-day; escalation paths are explicit from day one.

03
STEP 03 · HANDOVER · On schedule

Handover that holds in production

Fixed scope and timeline where we commit to both; documentation, runbooks, and knowledge transfer scheduled before go-live.

Commercial model

Lean structure.
Full-stack depth.

We invest in senior engineers and a tight delivery loop — not overhead for its own sake. You get direct access to the people who build and own the outcome, with commercials tied to milestones.

High-overhead studio model
Blended rates that fund layers of account management before build velocity shows up
Long staffing cycles before a stable squad is on your work
Scope spread across a rotating bench — continuity varies by week
Rate card often decoupled from who actually ships your release
White Label Solutions
Commercials aligned to milestones — outcomes first, not open-ended time
Senior engineers own delivery from architecture through QA
Two-week discovery produces fixed scope, schedule, and acceptance criteria
Lean overhead — investment goes into build velocity and tooling

// Detailed commercials follow discovery. Intro calls stay about fit, risk, and delivery — not rate-card theatre.
