We fired our
Accountants.
Then we built Simso. Because we were tired of working for our accountants instead of them working for us.
The Problem
It started with a shared frustration. You know the feeling: You are the business owner, yet your accountant pushes you around like a boss.
"Where is this receipt?""Why did you buy this?"
And when you actually need something—like a simple status report on your cash flow—you have to send an email and wait. And wait.
We needed Zero-Touch accounting. We needed a system that doesn't sleep, doesn't judge, and gives us a 24/7 instant response rate.
The Creators
Simso wasn't built by an agency. It was built by us, for us. And now, for you.

Darius Kupliauskas
Co-Founder & CEO
Ex-Ernst & Young Audit Consultant. Serial Entrepreneur.
Darius knows the rules inside out. He spent years auditing massive companies and realized that the same rigor could be automated for small businesses. He ensures Simso isn't just a "tech toy," but a robust financial fortress.

Tomas Talandis
Co-Founder & CTO
Ex-Mailerlite & Telia Engineering Manager.
Tomas specializes in solving complex problems for massive user bases. He looked at accounting and saw a data engineering problem waiting to be solved. He built the "Autonomous Engine" that powers Simso today.
We built the thing we needed.
We didn't set out to build accounting software. We set out to build a Business OS that lets founders focus on growth, not paperwork.
Simso is the solution to our own dreadful experiences. It turns the "Accountant" from a person you wait for into an app that waits on you.
Our Promise
"We will never build a feature just to tick a box. We build features that save you time, because we value our time just as much as you value yours."
