Get time back · Software and integrations
The software your business runs on. Built around how you work.
Portals, dashboards and booking systems that take the spreadsheets and the retyping off your team.
At a glance
- Web apps from $15,000
- 8 to 16 weeks to launch
- 90 days of support after launch
- Your code, your data, your accounts
Four shapes of web app. Yours probably fits one.
If it does not, that is fine: finding the right shape is half the work, and the discovery sprint exists for exactly that.
Software you sell to other businesses
Each customer gets their own private space, data and admin. Nobody can see anybody else's, enforced in the database, not just hidden on the screen.
Marketplaces
Two sides: people who list, and people who book or buy. Payments, reviews and what happens when a booking goes wrong: the parts that take real work.
Internal tools
The dashboard your team actually uses, built around how you work rather than how this year's software company thinks you should.
Booking and scheduling
Rooms, staff or machines, repeating slots, payment at booking and your real calendar. Double bookings, time zones and holidays handled.
Recent work
We also build and run four platforms for our own group, Pro Lifeset: SureshotVisa, Lifeset Overseas, CAIPS Notes Apply, SureshotTravel.
One team for the whole thing. Designed to last past launch.
Ask whoever quotes your web app: who designs the database, who builds the login, who runs the deploy. We answer all three with the same team.
Written as code, not stitched from templates
When the requirements get strange, and they always do, we change the software, not the requirements.
Logging in, done right
Roles, permissions, a record of who did what, password resets, two-factor. Built properly, not copied from a tutorial.
A database that survives growth
How the tables relate, what is indexed, what is never really deleted: the quiet decisions that keep month eighteen calm.
Fast on a real phone
Built for phones first. We measure load time before we ship and after each change, so it stays quick as it grows.
How it is built, and what you get
What we build it with
We change parts of this per project, but the bones are the same every time.
- The screens
- Next.js 16, TypeScript, Tailwind v4
- The engine
- Server Components, Drizzle, PostgreSQL
- Logging in
- Supabase Auth, or NextAuth or Clerk
- Where it runs
- Vercel, or AWS where your rules need it
- Taking money
- Stripe, Razorpay, or your own gateway
- Live updates
- Pusher, Liveblocks, Supabase Realtime
What you get
Every web app project ends with all of these in your hands.
- A written plan for how it will be built, before anyone writes code
- The output of a one-week discovery sprint, if the shape is not obvious yet
- Logging in, roles and permissions, done properly rather than copied from a tutorial
- A database designed for your business, and the migrations that got it there
- Admin screens your own team can use without calling us
- The connections to whatever else you already run
- The source code, the repository and the deploy keys, all yours
- Documentation, and a walkthrough for your team
- 90 days of support after launch, and a care plan if you want us on call
From your first message to every month after.
Tell us what to fix
A few lines on the form, or ask the assistant. A person replies within 4 business hours.

We build and launch
A website takes 2 to 6 weeks, a web app 8 to 16. Tested on real phones before launch.
We run it, every month
Hosting, updates and the systems kept working. Monthly plans cancel any time.

Planning the work
Build around the workflow your team needs to complete.
What to cover in the scope
- Map roles, records and the stages work passes through.
- Prototype the important tasks before expanding the feature list.
- Plan permissions, integrations, migration and operational support.
What helps us plan
Bring the spreadsheets, forms and tools used today, plus examples of exceptions. A discovery phase should separate the first useful release from later ideas.
How to judge the result
Test the work end to end, including corrections and failures. Successful software reduces uncertainty about what happens next, not just the number of clicks.
Tell us what the spreadsheet does today. We'll write the plan.
Half an hour on the phone and we will both know whether we are the right people for it. If we are not, we will say so.
Or call +1 437 524 3001 or toll-free +1 888 905 4003, or email hello@redenn.com.
