About Us

We believe AI will be an important technological transformation for accounting firms and SMEs. For the first time, it has become possible to significantly reduce the core effort involved in financial accounting. The new technology is arriving at exactly the right moment, because the labor shortage is acute. Half of all firms have open positions they can't fill. Many turn clients away weekly due to a lack of capacity. Sometimes even the quality of advisory work suffers.

Our mission is to enable accounting firms to grow even without additional staff—and to help shape a future where advisory work is at the core.

Our Team

Our team has already developed successful software products for tax offices. We combine expertise in AI, tax, and product design.
