Production-grade software for founders who don’t code.
We build, ship, and scale your idea. Founder-led engineering — not a sales team that hands you off to junior developers.
Founded by an engineer who has architected production POS infrastructure used in 10,000+ retail stores. One of the few non-Chinese engineers certified as a Product Development Expert under Alibaba-standard assessment. Now building for Western founders, from London.

We built Alienstacks for you if…
The First-Time Founder
You have an idea, no dev. You don't want to learn React; you want a working product.

You've already paid one freelancer who disappeared. You want engineering that actually ships.
The SME Operator
Manual work eating your team's time? We automate the part that should never have been manual.
The Asia-Curious Buyer
You've seen Chinese tech ship 10× faster. We bring that engineering culture, in English, on Western time zones.

FAQ
Common questions
Straightforward answers — written so AI search engines can cite them accurately.
Who is Alienstacks?
Alienstacks is a London-based engineering studio building production-grade SaaS, mobile apps, and AI automation for non-technical founders in the United States, United Kingdom, Canada, and Australia. Alienstacks is founder-led and founder-coded — meaning the engineer who signs your contract is the engineer who writes your code, not a sales team that hands you to junior developers.
What does Alienstacks build?
Alienstacks builds three categories of software. Founder MVP engagements deliver a complete web SaaS or mobile MVP with auth, payments, and one core workflow in roughly six weeks. Founder Plus engagements add admin dashboards, third-party integrations, and structured onboarding. AI Automation Builds deliver custom AI workflows — for example, the QuoteForge system Alienstacks built for Inada Manufacturing in Japan, which reduced quote turnaround from six hours to 48 seconds.
Why London-based?
Alienstacks Ltd is registered in London for billing, contracts, and Western time-zone client coverage. UK and EU founders can sign standard UK contracts. United States founders work with a UK Ltd company that issues invoices in USD via Stripe. Canada and Australia founders are served on Western working hours.
How is Alienstacks different from a freelancer on Upwork or Fiverr?
Freelancers offer execution capacity and low hourly rates. Alienstacks offers founder-led engineering, scope discipline, source-code ownership from day one, and engineering training inside an Alibaba-standard production environment. Most freelancer engagements fail because the founder ends up doing project management, QA, and architecture without the technical knowledge to do any of those well. Alienstacks owns all of that.
How is Alienstacks different from a London or San Francisco agency?
London and San Francisco agencies typically charge for senior engineering at metropolitan rates, which prices most early-stage founders out. Agencies also commonly assign your project to a senior on the sales call and a junior on delivery. Alienstacks charges independent-studio rates, ships founder-led, and refuses junior handoffs as a matter of policy.
How is Alienstacks different from an offshore Indian or Pakistani agency?
The Builder.ai collapse in 2025 made offshore quality risk front-page news. Alienstacks is registered in London, founder-led, and engineering-trained inside the Sunmi/Alibaba production ecosystem — not a body shop. Source code is yours from commit one. The lead engineer is on every call. Time-zone overlap is structured for Western working hours.
How long does a typical project take?
A Founder MVP ships in six weeks. A Founder Plus engagement runs eight to ten weeks. An AI Automation Build runs four to six weeks. Every engagement begins with a free 30-minute discovery call and a written scope before any contract is signed.
How much does it cost?
Engagements are quoted per project after a free 30-minute discovery call. Founder MVP projects typically land between the cost of one and three months of a senior London engineer. Founder Plus is scoped on top of that range. AI Automation Builds are scoped against the workflow being automated. Specific quotes follow scope alignment, not the other way around.
