Is This You?

The spreadsheet works — until it doesn't.

Only one person really understands it

The whole operation depends on one file — and the person who built it. When they're out, everything waits.

Copy-paste is the process

Your team re-types the same data between tabs, emails and other tools — hours every week that add nothing.

One wrong cell, and no one notices

A broken formula or a mistyped row quietly corrupts the numbers you're making decisions on.

It buckles as you grow

What worked at a handful of rows and people grinds to a halt as the business gets bigger.

Meet the Founder

James O'Sullivan

I started this because I kept seeing the same thing — a growing business quietly run on a spreadsheet that everyone was afraid to touch.

The answer usually isn't another off-the-shelf app. It's software built around exactly how your business already works — replacing that fragile spreadsheet with something your whole team can rely on.

15+ internal tools deployed. 15 years in product & engineering. From spreadsheet to working software in weeks, not months.

What Clients Say

They ditched the spreadsheet.

Alex testimonial

Every tool we'd tried before made us work their way. Userflo built something around how we actually operate — it's the first system that just fits.

Jeff testimonial

Our data was spread across five different apps that never talked to each other. Userflo tied it all together into one system in a matter of weeks.

Liam testimonial

What I appreciated most was that James actually understood how our business worked first. The software came second — and it fit like it was built for us, because it was.

Jordan testimonial

Our onboarding was a mess of spreadsheets, emails and things slipping through the cracks. Userflo replaced it with one system built around exactly how we do it.

Ken testimonial

I'd spoken to a few agencies and none of them really got it. James asked the right questions and built software that matched how we actually work — not some template.
