New hires are nowhere in sight. More capacity is.

PRUVAGE® is the sovereign AI platform for tax advisors and auditors. It makes firm knowledge usable across the team, takes on recurring routine work, and fits into existing systems. Review, approval, and accountability remain with the licensed professional.

Work is increasing. Knowledge remains concentrated in a few people.

More regulation
Knowledge held by key people
Quality & capacity under pressure

PRUVAGE® preserves your firm’s knowledge and makes it usable every day—complementing DATEV and Microsoft 365, GDPR-ready and fully EU-hosted.

More time for clients and advisory work. One licence for the whole firm—not per-seat pricing.
