About Staxiom

Where is Staxiom headquartered?

Staxiom is headquartered in Brea, CA.

What does Staxiom do?

Staxiom provides diligence-grade accounting for startups — bookkeeping, tax prep, and capital strategy, with an AI-assisted R&D tax credit engine reviewed by EY-trained CPAs. Founded by the team behind Ardius, the R&D tax credit company Gusto acquired in 2021.

What problem does Staxiom solve?

Most startups either skip R&D tax credits entirely or leave money on the table because claiming them correctly is complex, and by the time a fundraise or acquisition brings in real diligence, sloppy books and last-minute tax decisions turn into a scramble instead of a formality.

What's Staxiom's solution?

Staxiom combines AI-driven credit-finding with EY-trained CPA review to handle bookkeeping, tax prep, and capital strategy for startups — surfacing R&D tax credits and other incentives automatically, with books kept clean and diligence-ready from day one.

What makes Staxiom notable?

Led by founder Joshua Y. Lee, who spent 13 years at EY's R&D tax credit practice before starting Ardius, an R&D tax credit company later acquired by Gusto in 2021.
