Mondaycar

Mondaycar is a Paris, France-based vehicle rental and leasing provider serving companies and professionals across metropolitan France. It markets two complementary formats: "Flex", a short-commitment rental from three months drawn from in-stock vehicles and delivered within about seven days, and "LLD" (long-term leasing), to which customers can switch at any time, either keeping the same vehicle or ordering a specific configuration, in exchange for lower monthly payments. Contracts run from 3 to 36 months, and up to 48 months in some cases, with no increased first rent and no down payment beyond a refundable security deposit; mileage terms can be adjusted during the contract, with excess mileage billed at contract close.

Monthly rents are all-inclusive and invoiced as a single bill covering comprehensive insurance, maintenance and servicing, tyres, registration (carte grise), 24/7 roadside assistance, a replacement vehicle, technical inspections, GPS tracking, traffic-fine and claims handling, delivery and collection at the customer's address, and a dedicated adviser. The catalogue spans city cars, SUVs and light commercial vehicles across petrol, diesel, hybrid and electric powertrains — including the Renault Clio, Citroën C3, Peugeot 208/2008/3008/5008, Volkswagen Polo/Golf/T-Roc/ID.3/ID.4, Toyota Yaris/Corolla/RAV4, Tesla Model 3 and Skoda Enyaq — with advertised entry prices from roughly €450 to €869 per month including tax; vehicles outside the catalogue can be sourced on request.

The company also offers Mondayfleet, an online fleet management platform presented as a replacement for spreadsheets. It is compatible with both Mondaycar-supplied and customer-owned vehicles and provides geolocation, live mileage tracking and trip history, driver and vehicle assignment, fine handling and usage monitoring, plus automated calculation of French vehicle taxation such as the CO2 tax, benefits-in-kind and TVS. Mondaycar also publishes fleet-management guidance content on its blog, covering topics such as maintenance cost comparisons, vehicle depreciation and fleet safety compliance.

Founding story

Mondaycar was founded by Sébastien Louit, who serves as founder and CEO and is based in Paris. He states that since 2019 he set out to simplify fleet management for SMEs by creating a constraint-free alternative, so that companies could focus on growth rather than vehicle logistics. His earlier career included a junior business analyst role at Microsoft France beginning in 2010.

Business model

Mondaycar rents vehicles to businesses under fixed all-inclusive monthly payments that bundle the vehicle with insurance, maintenance, tyres, registration, assistance, replacement vehicle, inspections, fine and claims management, delivery and the Mondayfleet platform, billed on a single invoice. Customers pay no increased first rent, only a refundable security deposit. Revenue arises from short-commitment Flex rentals (from three months) that can convert into longer-term LLD contracts at reduced monthly rents, with additional billing for excess mileage or reconditioning assessed at contract close.

Fixed all-inclusive monthly rents per vehicle, quoted from about €450 to €869 including tax per month for catalogue models depending on vehicle, with pricing set by contract duration (3 to 36 months, up to 48 in some cases) and mileage allowance. Lower monthly rents apply on conversion to long-term LLD contracts. Additional charges may be billed at contract close for excess mileage or reconditioning following a joint end-of-contract inspection; a refundable security deposit is taken at the start.

Traction

The company states its fleet has covered millions of kilometres since 2019 (equated on the site to about 750 circuits of the Earth without leaving France), that its solution saves customers roughly three hours per vehicle per month, and that it has handled traffic fines on customers' behalf. It reports a Trustpilot score of 4.8/5. The Techstars job board lists the company at 1-10 employees and seed stage.
