For people with a SaaS idea
Skip the engineers, the agencies and the six-month MVP. Tell JAI what you want to build — and get a real, paying-customer-ready SaaS, live this week.
No code, no agencies. From idea to live SaaS in an afternoon.
Built for people who have ideas, not engineers
Built on JAI
These three SaaS products were pitched in a sentence, built on JAI, and turned a profit in months — not years.
AI sales platform for bespoke joinery makers
Order intake, quote rendering, manufacturer dispatch and customer portal — for high-end joinery makers selling £20k+ doors.
In its first 6 months
Household management for private homes
Staff rotas, contractor scheduling, expense tracking and AI concierge for owners of premium homes and estates.
In its first 6 months
Timber doors, sold through a network of installers
Customers configure bespoke timber doors online, installers measure and fit, and partner manufacturers build to spec — all orchestrated through one platform.
Across multiple manufacturing partners
Grassroots football coaching app
Player rosters, training plans, fixtures and parent comms for small clubs and academies — free for coaches, monetised through in-app ads.
From in-app advertising
Four founders. Four niches. Four live businesses, paying their own bills.
What you get
Everything a SaaS needs to take a paying customer — sign-ups, billing, email, automations, files, a beautiful UI — built in from day one.
People can join your SaaS, log in, and have an account from day one.
Built around what your users do — not a clone of someone else’s app.
Sell products or plans straight from your SaaS. Cart, checkout, the lot.
Take subscriptions and one-off payments. Get paid from launch day.
Welcome notes, reminders, receipts — sent from your domain.
Nudges, sequences and reminders that keep your users coming back.
Useful if your product is built around time, sessions, or events.
Where your users upload, store and share their work.
A branded space your customers actually want to log into.
AI built in
You don’t need to hire an AI team. Every SaaS you build with JAI ships with these from day one — wired into your data, your customers, and your workflow.
Document parsing
Drop in an invoice, a receipt, a contract — even a photo of one. JAI reads it, pulls out everything that matters, and turns it into a row in your database.
Photo render studio
Generate product photos, lifestyle scenes and marketing visuals in seconds. Use them on your storefront, in emails, on your social — no camera, no agency, no shoot day.
Smart pricing
JAI watches what wins and what doesn’t — quotes accepted, deals lost, margins realised — and suggests the right price for your next sale.
How it works
Skip the months of planning, the cofounder hunt and the six-figure build quote. Get a real SaaS in your hands today — and shape it as you go.
A sentence about who it’s for and what it does. That’s the whole brief.
It works out what your users will need — and the way it should fit together.
Beautiful screens, a working database, and an AI teammate, all ready to use.
Your own web address. People can sign up, pay, and start using it.
Want a new page or a different flow? Just say so. JAI updates the live product.
Add features, fix things, polish the experience — all in chat. No team needed.
Integrations
Out of the box. Connect Xero or QuickBooks for accounting, Gmail or Microsoft 365 for email, Stripe for payments, Mailchimp for marketing — and a dozen more. Your customers click, sign in, and they’re synced.
Pull inboxes and meetings into your SaaS so it stays in sync with the rest of your customers’ day.

Your AI cofounder
Every SaaS you build comes with JAI — an AI that already understands your product. Ask in plain English and it ships features, replies to your users, sends emails, chases payments, and tidies the rough edges.
Who it’s for
The hard part of starting a SaaS isn’t the engineering — it’s having the right idea and the patience to ship it. JAI takes everything else off your plate.
Big idea, no co-founder yet. Skip the “learn to code” detour.
You know the problem inside-out. Now you can build the fix.
Ship in a weekend, not a quarter. Iterate while it’s still fun.
Build the SaaS on the weekend without giving up the day job.
Spin up new client products without burning your engineering team.
Get a real product in users’ hands before you raise a penny.
Ideas worth building
You don’t need to be the next Salesforce. The most profitable SaaS businesses are tiny, focused tools — for dog walkers, for piano teachers, for letting agents. The one you’ve always wanted.
Pick a niche you know. JAI builds the product.
Pitch the idea. Get a working SaaS — with sign-ups, billing and AI — on its own web address in minutes.
