The shift

Owning your software no longer means maintaining it.

The Old Model

Rent SaaS

  • Pay for bloated features you never use
  • Bend your workflow to fit their product
  • Per-seat pricing that's anti-growth
  • Price hikes you can't control

Build with a Devshop

  • High maintenance cost — forever your burden
  • Expensive to build, and takes time — lots of back-and-forth
  • Every change is a new invoice
The New Model

With

Founding.dev

  • You own everything — code, data, and infrastructure
  • One flat price. No per seat.
  • Change it in plain English, anytime
  • Bank-level security, built in.
  • We build it and run it — the maintenance isn't on you

Replace or Build Software

How it works

1

Tell us what to replace or build

Replacing an expensive, bloated SaaS — or building something brand-new for your team? Either way, just tell us what it needs to do and who it's for.

2

We build it around your workflow

Start from a proven, expertly built template. You can customize further with our editor in plain English, or let our engineers handle it.

3

You own it. We can run it.

The code and data are yours to keep. Want it managed? We host, update, and maintain it for one flat price — or run it yourself.

Get started

THE NUMBERS

Renting only gets more expensive. Owning pays for itself.

Pricing

Rented SaaS: A subscription, usually per person

Owned software: A one-time build, plus an optional flat fee

How cost grows

Rented SaaS: With every hire, plan, and renewal

Owned software: Flat. More people doesn't move the price

Who owns code and data

Rented SaaS: The vendor

Owned software: You

Customization

Rented SaaS: What the vendor ships

Owned software: Built around your work

Leaving

Rented SaaS: Export your data and rebuild

Owned software: You keep everything

The full guide includes the break-even formula and a worked example.

Real savings

$30,000 $8,800 a year

One claims-management company replaced its rented tools this way and cut software spend by about 70%.

The SaaS Replacement Guide: Your Questions Answered

A step-by-step playbook: how to spot the tools draining your budget, a build-vs-buy check, the real cost math with a break-even formula, a migration plan, how to switch without downtime, the common mistakes, and a 30-day action plan.
Yes. Enter your work email and we'll send a copy to your inbox. No cost, no sales pressure.
Owners, operators, and ops leads at companies where software costs are climbing and the tools no longer fit how the team works.
There's no one-size number. Compare the one-time build cost against what you spend now each year on the tools you're replacing. Over a few years, owned software often costs well below the SaaS it replaces. The guide walks through the math.
Not with a proper plan. You export your data before you leave, check it's complete, and import it with checks along the way. The guide covers this step by step.
No. With Founding.dev you start from a proven template our engineers built, then customize it in plain words. Or we build the whole thing for you. Either way, you own the result.
You pay one flat price for the whole company, not per person, so your bill doesn't grow every time you hire. And you own the code, the data, and everything that runs it.
Yes. Bank-level encryption, it meets industry rules, keeps a record of who did what, and supports one secure login. Your data is never used to train AI.
