Why we're different

There's a reason founders switch to Staxiom instead of a generic bookkeeping app.

Built to hold up under scrutiny

Books and numbers built diligence-grade from day one — not cleaned up right before someone asks to see them.

Founder-built

Staxiom's CEO founded Ardius, the R&D tax credit company Gusto acquired in 2021, so the team knows what diligence asks because they've been asked.

Big 4 pedigree

Our team includes former Big 4 accountants, plus founders and investors who've been through a raise.

Provenance

We've been on the other side of the table.

Sovereign's Capital portfolio companies don't get a lead-gen operation with a calculator bolted on. Our team includes former Big 4 accountants, so the review your team gets is the same one we'd want for our own books.
