Background on nextesy
nextesy is a Swiss AI startup developing the «AI standard for administration» – an autonomous operating system for running a business. nextesy was founded in Zurich in 2023 and has its roots in the ecosystem of ETH Zurich and the University of St. Gallen (HSG). After two years of development in stealth mode, nextesy launched commercially in Switzerland in April 2026.
Unlike traditional accounting software that adds AI as an extra add-on module, nextesy is built «AI First»: the AI handles routine tasks such as receipt capture, account assignment, payment reconciliation, and dunning, while business owners only review. The promise: «Orders, invoices, accounting – done.»
Just a few months after its market launch, nextesy had over 2'000 active customers. In October 2026, nextesy was selected among the Top 20 out of more than 1'400 startups at the Slush 100 in Helsinki.
Products & platform
The nextesy platform comprises the following core modules, which all run on a shared database:
CRM: Customer and contact management with a payment traffic light showing each customer's payment behavior at a glance
Quotes & orders: From quote to order to invoice in a single flow, including product and item management
Invoices & dunning: Swiss QR-bills, recurring invoices, foreign currencies, and automated payment reminders
AI accounting: AI-guided account allocation, open-item accounting, sub-ledgers, and automatic VAT handling
E-banking: Connection to Swiss banks with automatic detection and booking of incoming payments
