Autonom products and services
Autonom offers daily and longer car rentals to individuals, companies and public institutions. Its wider services include operating leases, fleet management, replacement cars, roadside assistance, transfers with drivers and equipment leasing. The mix makes Autonom both a rental supplier and a business mobility provider.
For corporate customers, an operating lease combines vehicle use with agreed fleet services over a longer term. This differs from a short rental, where the customer books a vehicle for days or weeks. Autonom’s own fleet and branch network support both models.
Where does Autonom operate?
The company began in Piatra Neamț and has an administrative office in Bucharest. Autonom’s current site identifies rental service in Romania, Hungary and Serbia. Counts for agencies and vehicles change over time, so they should be used only with a dated source rather than as permanent entity facts.
Who owns Autonom?
Autonom’s investor site names Marius Ștefan as founder, shareholder and chief executive. It identifies Dan Ștefan as a current shareholder and managing partner who joined the business in 2006. Autonom Services has bonds traded on the Bucharest Stock Exchange, but a listed bond does not make the company’s shares publicly listed. No corporate parent is named.
Autonom history and recent developments
Autonom says it was founded in Piatra Neamț in 2006. It expanded from rent-a-car into operating leases and other fleet services. Acquisitions have also added scale, including the operating-lease activities of BT and Tiriac in earlier years.
On 7 July 2026, Autonom issued the AUT31E sustainability-linked bond with a 2031 maturity, according to its investor page. The bond is a financing development for the wider fleet and mobility business. It does not change the ownership description above.
