Guests book through the platform and access cars 24/7 via keyless phone unlock at Sigvi-managed parking lots, eliminating the counter queues and trust issues that plague traditional rental.The company serves both B2C travellers (tourists, long-term renters, car replacement) and B2B clients (corporate fleets, insurance replacement vehicles, OTA partners). Sigvi is live in Lithuania and Poland, targeting the ~35% of the €72B European car rental market still served by independent operators with no technology infrastructure.
