What is FIT software?

FIT (Flat monthly fee, Innovative, Tailored) is custom software as a subscription: made to measure for your business, with hosting and alterations included, and adjusted as you grow. SeeSaw Labs maps your process, builds a focused tool in a few weeks, then hosts, maintains, and keeps improving it for one flat monthly fee. You get software built around your process, a price you can plan around, and the option to own it outright whenever you want.

AI and decades of reusable building blocks have brought the cost of custom software down. What’s left is paying for it all at once and the worry of owning software nobody can maintain. We remove both.

Our process

The 5 Ds, tailored to you

Like a seesaw, we balance strategic vision with practical execution. Product, design, engineering, and your team work side by side from day one, so we build the right small thing, not a big platform nobody wants to use.

  1. Step 1 · Free

    Discover

    A 30-minute FIT Check. We research your business ahead of time and tell you honestly whether custom software will pay for itself.

  2. Step 2

    Define

    We map the manual work, mark up the one job worth automating first, and agree on what success looks like.

  3. Step 3

    Design

    A prototype your team can click, tested with the people who will use it every day.

  4. Step 4

    Develop

    We cut and sew a focused first version, live within a month and connected to the tools you already use.

  5. Every month

    Delight

    We keep it running and keep tailoring it, every month.

Who it’s for

Cut for operations-heavy businesses without a dev team

This works best for owner-led companies of roughly 20 to 200 people, running on four to eight SaaS tools plus spreadsheets, with people filling the gaps by hand.

  • Healthcare administration
  • Property management
  • Insurance agencies
  • Professional services
  • Logistics
  • Anything with intake, scheduling, or approvals

It’s probably time if…

  • You’re about to hire someone to do a job software should do
  • Someone’s whole role is copying data between systems
  • A renewal just landed for a tool you half use
  • Your software is wearing thin and you need what’s next

Have your own engineers, or want the code from day one?

Our project-based engagements are a better match. Explore product design and development, custom software development, or Fractional CTO services.

Already started something with AI?

Bring us your existing AI projects. We’ll finish buttoning them up.

Plenty of teams have a prototype someone spun up with AI. It demos well, then frays on real data, real users, or the second edge case. We keep what works, fix what doesn’t, and get it across the finish line.

  • “It works on my laptop.”It’s never been deployed, secured, or backed up.
  • “Only one person understands it.”The person who built it is busy, or gone.
  • “It almost does the thing.”The last 20% is where it keeps coming apart at the seams.

Your prototype isn’t wasted. It’s the best set of measurements we could ask for.

The Finish-Line Audit

One fixed price. A written plan to finish what you started.

We review your prototype, code, and data, then tell you what to keep, what to rebuild, and what it takes to get it live. Keep the plan whether or not you work with us.

Frequently asked questions

FIT stands for Flat monthly fee, Innovative, Tailored. It’s SeeSaw Labs’ model for custom software as a subscription: we build software made to measure for your business, then host, maintain, and keep improving it for one flat monthly fee. Nothing upfront, and you can buy it out anytime.
SaaS is off the rack: one product cut for everyone, priced per seat, and changed on the vendor’s roadmap. FIT software is made to measure for your process, priced as one flat monthly fee, and altered on your roadmap. And unlike SaaS, you can own it outright.
One flat monthly fee, set by scope and complexity and quoted after your free FIT Check. It covers the build, hosting, maintenance, and ongoing improvements. Nothing upfront. No surprise invoices.
A focused first version is usually live in a few weeks. We start with the job that costs you the most time, ship it, then keep tailoring it month by month.
While you subscribe, we own and run it, which is why you never have to maintain it. If you ever want to own it outright, you can buy it out at any time.
When a SaaS tool works for your process, use it. Custom software wins when your team is taking in and letting out around tools, retyping data between them, or paying for features nobody uses. We often replace several baggy tools with one made for you.
Yes. Most builds connect to the accounting, CRM, scheduling, and document tools you already rely on, so data moves on its own instead of by hand.
No. We built this for companies without engineers. You bring the business knowledge; we handle the technology from design to hosting.
Two ways. AI speeds up how we design and build, which is what makes custom software affordable. And where it helps, AI goes inside the product, like handwriting recognition that cut one client’s manual data entry by 80%.
Yes. Where it makes sense, we build on open-source models that run in your cloud or on your own hardware. Your data stays under your control, there are no per-use fees, and you’re not locked to one AI vendor’s pricing or policies.
Usually not. We look at what you’ve built, keep what’s sound, and rebuild the parts that won’t hold up. Your prototype is often the clearest spec we could ask for.
Yes. Picking up a half-finished tool and getting it across the finish line is one of the most common ways we start working with a new client.
Your data is always yours. If you cancel, we export it for you in a standard format, and you can choose to buy the software outright instead of switching it off. Notice periods and minimum terms are set out in your agreement.
