ReVolt: business plan
Business plan written as a group (Sonia, Auxence, Ruben, Ilyane) and presented on 12 May 2026 for ReVolt, an electric retrofit startup concept: converting combustion vehicles to electric instead of replacing them.
The concept
ReVolt starts from the customer's own vehicle. A diagnosis first checks that it is compatible with a retrofit, then the combustion engine is replaced by an electric motor, with the battery and electronics it needs. The vehicle then gets its administrative update so it can legally drive as an electric vehicle.
With each customer, a usage profile (daily mileage, driving zones, charging needs) sets the right range among three battery sizes, 170, 250 or 350 km, to avoid the weight and cost of an oversized battery. The offer targets individuals, companies running fleets and local authorities.
Market
The French retrofit market is estimated at 150-200 M EUR in 2024 (Avere-France), growing 20 to 30% a year, driven by regulation (the end of new combustion cars in 2035, low-emission zones) and public incentives. Around 60% of owners of older or commercial vehicles consider a retrofit.
Porter's five forces and a SWOT matrix shaped the strategy: a market with few established players but fast growth, customers sensitive to price and reliability (hence extended warranties and transparent costs), and strong constraints such as kit homologation. The main threats identified: changing subsidies and how fast battery technology moves.
The offer
Three all-inclusive packs for light and heavy commercial vehicles: motor kit, lithium iron phosphate (LFP) battery for longevity, certified installation, UTAC homologation and a 2-year warranty.
The first target market is the Paris region, where the Greater Paris low-emission zone pushes owners of combustion vehicles to find a solution, with two segments: classic cars and light commercial vehicles. Combining state incentives (a conversion bonus of up to 5,000 EUR, an ecological bonus, a zero-interest loan) with regional and City of Paris grants can cover more than half of the cost. Through subrogation, those grants come straight off the invoice: the remaining cost starts at 4,442 EUR for a van with a 170 km range for the lowest-income households, and ReVolt keeps around 4,500 EUR of margin per vehicle, whatever the grants.
Figures
- Forecast 2026 revenue: 2.6 M EUR
- Variable costs (kits, batteries, insurance): 1.66 M EUR; fixed costs: 370 k EUR, including 174 k EUR of salaries and 140 k EUR for the warehouse
- Forecast profit: 560 k EUR
- 180 vehicles converted in the first year
- Funding need: 315 k EUR (UTAC homologation, an initial stock of 15 kits, a 4-month salary reserve, workshop equipment), covered by 100 k EUR of equity and a 200 k EUR loan, as a French SAS
