Rethink! Accounting is Germany's leading strategy event for accounting managers, finance decision-makers and controlling professionals, bringing together over 390 participants at the Radisson Blu Hotel in Frankfurt each year. This April, Maesn will be there as an exhibitor.
Germany's most concentrated accounting decision-maker audience.
The event covers exactly the challenges Maesn helps software teams solve — automated invoice processing, accounts payable automation, ERP integrations and the digitalization of accounting workflows. For SaaS teams building products in or around the accounting space, Rethink! Accounting is one of the most concentrated audiences of finance decision-makers in the DACH region.
Meet Maesn - the Unified API for every ERP and accounting system.
If you are building a software product that needs to connect to your customers' accounting or ERP systems, come find us. Maesn's unified API handles the full complexity of connecting to DATEV, Lexware, sevdesk, Sage, Microsoft Business Central and 25+ more systems behind a single REST interface — so your team ships integrations in days rather than months and never maintains them again.
Arrange a meeting in Frankfurt.
Rethink! Accounting 2026 takes place 20 to 21 April at Radisson Blu Hotel Frankfurt. Reach out to arrange a meeting in advance — we look forward to seeing you there.
