Sigvi, a Vilnius-based AI revenue agent for the car rental industry, has raised €1.2 million in pre-seed funding to accelerate product development and international expansion.
The round was led by Helsinki-based venture capital firm Superhero Capital. Vladas Lašas, Chairman of the Lithuanian Business Angel Network (LitBAN) and co-founder of the Carbon War Room, participated alongside other angel investors.
Vytis Šliažas, CEO and co-founder of Sigvi, said, “Europe is travelling more than ever, but the car rental experience hasn’t evolved at the same pace. Travellers expect to book a car as easily as they book accommodation. Meanwhile, thousands of quality vehicles owned by independent operators sit idle because they lack the technology to reach those customers. We’re building the AI layer that connects both sides, unlocking cheaper, greener, and fully digital car rental.”
Founded in 2023 by Sliažas, Ignas Gibas (COO), and Mindaugas Banaitis (CTO), Sigvi is an AI revenue agent for the car rental industry. The company says it aggregates vehicles from independent fleet operators and private owners, and manages all operations end-to-end.
Its AI engine handles dynamic pricing, bookings, and keyless 24/7 vehicle access, as well as automated vehicle inspections, predictive maintenance scheduling, and customer support.
Sigvi notes that it offers a wide selection of professionally managed vehicles, typically priced around 30% below traditional international rental brands, available from pickup locations with no counter and no queue.
The company cooperates with the Kemi network of car service centres, where each vehicle is regularly inspected and maintained, starting from its initial preparation for rental. It claims that it replaces car parts more frequently than recommended by the manufacturer. It changes tyres every season. In warm seasons, the cars are fitted with summer tyres, while in cold seasons they run on winter tyres.
Highlighting its sustainability quotient, the startup says the platform uses existing second-cycle vehicles instead of buying new fleets, offering a more sustainable model by maximising the use of cars already on the road rather than adding new ones.
Sigvi launched operations in Poland in June 2026 and currently manages more than 200 vehicles.
“Sigvi has found a structural inefficiency in a massive market and built an elegant solution around it. We see a clear path for Sigvi to become the digital infrastructure layer for independent car rental across Europe,” said Gytenis Galkis, Partner at Superhero Capital.
The company plans to use this capital to further develop its AI automation platform and increase its managed network to 2,000 vehicles within two years.
