Custom Software

Your custom software, in front of users in 10 days.

Most custom builds take months before a single user touches them. We ship a working MVP in 10 days, at about 20% of what a traditional human team would cost, then carry the same codebase into production.

What you get in 10 days

A working product.
Not a mockup.

Something you can put in front of users, investors or a pilot customer, and learn from.

01

Core flows that work

The two or three journeys your idea lives or dies on, built end to end. Not screens. Software.

02

Real data, real accounts

A proper database, sign-in and roles, so test users can actually use it and you can read what they do.

03

Live on a real URL

Deployed, tested and monitored. Share the link on day 10 and start learning the same afternoon.

How it works

Three steps.
No discovery marathon.

  1. 01 · Minutes

    Describe your idea

    Tell our assistant what you want to build. A ballpark timeline and cost lands in your inbox. No sales call.

  2. 02 · 10 days

    We ship your MVP

    Scope locked on day one, working software every day after. Follow it on a live dashboard with daily reports.

  3. 03 · When it works

    Build it for real

    Your MVP becomes the foundation of your production product. Same codebase, same standards, carried forward.

How is that possible?

Not by cutting corners.

Every Redplum engineer runs a team of AI agents on Redplum Delivery OS™. A small pod does the work of a much larger team, with the checks built in.

  • Quality Agent reviews every commit against your standards before a human signs off.
  • Ops Agent writes your daily progress report and flags risks early.
  • Domain Skills bring proven patterns for your industry, so we don't learn it on your budget.

After the MVP

Fast doesn't mean throwaway.

The biggest fear with fast and affordable is paying twice. So we don't build disposable prototypes. When the idea proves out, the production product grows from the MVP's own code.

Domain Skills that compound.

Any idea works. These are the verticals where our encoded patterns make the first 10 days go further.

Most ideas are bigger than their first test needs to be. The MVP Scope Builder splits yours into what ships in the 10-day MVP and what waits for later.
