Is it a good time to start a car-sharing business? Absolutely.
The car-sharing market is booming – it's estimated to grow 20% every year and reach a $20 billion market value by 2032. That's nearly a sevenfold increase from 2022's $2.9 billion valuation.
Despite app-based vehicle sharing being a relatively new entrant in the mobility ecosystem, it has exploded in popularity. People have been quick to pick up on its convenience and ease of use, especially in urban centers where maintaining a private vehicle grows increasingly costly and bothersome.
This spells an opportunity for entrepreneurs keen to answer real mobility demand.
But what is car-sharing and how does it work? What does the business model look like? And what are the first steps for getting started?
Find the answers below.
What is car-sharing and how does it work?
Car-sharing is an app-based mobility service that allows individuals to rent vehicles on a short-term basis. With this service, users gain access to a fleet of vehicles which are typically stationed throughout a city, ensuring that there's always a car conveniently nearby.
The user's journey and benefits of car-sharing
Through an app on their smartphone, users can locate, book, and unlock the closest available vehicle, as well as pay for their journey automatically by adding payment details, thus providing a seamless experience and quick access to a car. Other common benefits for users include not having to worry about fuel or insurance, as those are included in the price.
Cities often encourage the use of shared mobility since it helps decongest streets, free up parking, and minimize the environmental impact of private vehicles on the city. Accordingly, public-private partnerships are common, conferring further benefits for users of this type of shared mobility: free parking, free use of bus lanes, and more.
How does car-sharing work: the business perspective
On the business side of things, the operator is responsible for ensuring that maintenance and logistical tasks for their fleet are taken care of.
This includes regular maintenance tasks, such as vehicle check-ups, repairs, fuel fill-ups, and cleaning. Also, if you have a free-floating model (where users can leave their cars anywhere), the operator should regularly relocate cars to optimal locations for continued user convenience and reliability.
Beyond deploying and maintaining their fleet, operators also oversee the smooth functioning of their mobility app, as well as take care of user verification, namely, ensuring that the people signing up are who they say they are and have valid driver licenses. Of course, like any other business, customer support and other responsibilities tied to running the operation are a given.
The car-sharing business model
So far, we have listed a lot of expenses – maintenance, management, insurance, IT. Add to this salaries, operational overheads, and buying or renting the fleet itself. How do businesses recoup all these expenses and turn a profit?
Note: Since car-sharing businesses operate at scale, they should aim to negotiate lower rates with service providers.
Car-sharing businesses make use of several revenue sources. First and foremost, customers are charged for the time/distance use of the car. Additionally, branding and cross-promotion partnerships (e.g. advertising on the car or the app) are often used to secure additional revenue. It may also be sensible to create membership or loyalty programs to ensure recurring revenue, by offering subscribers added benefits, such as access to premium cars or longer reservation times.
The aim is to have your cars on the road as much as possible, so enterprises typically focus on maximizing vehicle usage and revenue per vehicle. Finding success is about finding balance in a constantly changing landscape – having too few cars may lead to overbooking and dissatisfaction with lack of availability, whereas having too many will lead to inefficient use of resources.
How to start a car-sharing business
As with any business, launching a car-sharing project requires research, investment, development, and strategy. Let's take a look at each in turn.
1. Market research
When exploring opportunities for starting a car-sharing business, numerous factors must be considered.
Audience and demand
Understanding the demographics, preferences, and behaviors of your potential users is crucial. As is determining the level of demand. Some questions you should answer include:
- Who is my target audience – urban commuters, occasional travelers?
- What are their demographics? How should you communicate with them?
- What segment offers the most promise – B2C, B2B?
Competition
Identifying who's already operating in your area and why (or why not) can help you get a better grasp of what works and what doesn't. Some questions you should answer include:
- Who are my competitors – other car/ride-sharing businesses, public transportation?
- How can I differentiate my business from others?
- Has any previous similar business failed in this area – why?
Legal and logistical considerations
Determining whether there are any legal/practical barriers to launching your operations is a smart thing to do before you invest too much time and money into your project. Consider:
- What are the legal requirements for operating this type of business in your area?
- How will you handle insurance and liability issues for your fleet?
- How and where will you run your day-to-day operations? If you're thinking about going electric – does the area have the necessary infrastructure?
While answering these questions isn't necessarily a prerequisite for launching your business, dealing with them early on can save you a lot of headaches down the road.
2. Investment
How much capital do you need to launch a car-sharing business?
It depends most on whether you're planning to rent or buy vehicles for your fleet. While renting is more accessible in the short term, it will take a sizable bite out of your profit. Owning your vehicles is typically the preferred option, as this offers price stability, long-term cost efficiency, freedom of operations, and other benefits.
To get a ballpark estimate for the starting investment, you should add up the total price of cars (EUR 12,000-20,000 per vehicle), insurance, car-sharing software procurement and maintenance, as well as expected operational overhead for getting started. It may also be wise to put aside some funds for unexpected expenses such as repairs.
3. Development and launch strategy
Securing the vehicles and necessary permits can take a while, and you should account for this. During this time, you should put your plans into practice. Establish maintenance protocols and logistical plans for efficient fleet management. Implement user verification processes and responsive customer support for a secure and positive user experience.
As to the IT infrastructure, you can save a lot of resources by choosing a white-label IT solution to power your app and dramatically accelerate your time-to-market. Platforms like ATOM Mobility can equip your business with the app you need – all you have to do is customize it.
Speaking of customization, don't forget about branding. Create a compelling brand identity and plan for targeted launch and marketing campaigns to generate awareness the moment your business is ready for its first customers.

How to fully automate maintenance tasks and alerts for rental fleets
🚗 Scaling a rental fleet without automating maintenance? That’s risky. Spreadsheets and routine checks might work at 20 vehicles, but once you grow past 50, things start slipping. More operators are using IoT telematics, automatic error codes, and mileage-based service alerts to catch issues early and keep vehicles available. See how rental fleet maintenance automation helps you scale without chaos.

How to automate maintenance alerts for rental fleets
Rental fleet maintenance automation is becoming essential for operators who want to scale without increasing operational complexity. Whether you manage cars, scooters, bikes, or mixed fleets, manual inspections and spreadsheets quickly fail once your fleet grows beyond a few dozen vehicles.
Breakdowns, missed services, and delayed repairs directly affect uptime, revenue, and customer satisfaction. Modern fleet technology makes it possible to automate maintenance using IoT telematics, onboard sensors, automatic error codes, mileage-based triggers, and structured dashboards.
Why manual maintenance tracking does not scale
In small fleets, maintenance is reactive. A customer reports an issue. A staff member checks the vehicle. Someone creates a task manually. This works for 20 vehicles, but for 200 it’s just too much work.
As fleets expand, issues are discovered too late, standards vary between locations, and staff spend more time coordinating than fixing. Rental fleet maintenance automation shifts operations from reactive repairs to preventive, system-driven workflows.
Using IoT telematics to monitor vehicles in real time
IoT telematics devices collect live data such as location, battery level, ignition status, engine health, and mileage. In car rental and car sharing fleets, telematics also track fuel levels, driving behaviour, and diagnostic information.
Instead of waiting for user reports, the system can trigger alerts automatically. For example:
- when a battery drops below 20 percent
- when a vehicle reaches a service mileage threshold
- when a vehicle leaves a defined service area
- when the vehicle receives a few negative reviews
This data feeds directly into the fleet platform, where workflows assign tasks automatically, reducing response times and eliminating internal coordination delays.
Onboard sensors and automatic error codes
Modern vehicles generate diagnostic trouble codes when systems fail. In connected fleets, these codes appear instantly in the operator dashboard.
If a vehicle reports a brake or engine warning, the system can block it from new bookings, notify technicians, and create a repair task automatically. In micromobility fleets, IoT modules detect tilt events, battery degradation, failed unlock attempts, or controller errors.
Digital reporting further improves vehicle availability. ATOM Mobility’s vehicle damage management feature shows how structured workflows reduce downtime and improve transparency.
Mileage-based and time-based service automation
Rule-based servicing is one of the most effective elements of rental fleet maintenance automation.
Operators can set simple service rules, such as:
- changing oil every 15,000 km
- checking brakes every 20,000 km
- running a safety check every six months
When a vehicle reaches one of these limits, the system creates a task automatically. The vehicle can also be temporarily removed from booking until the service is done. This becomes especially important when operating in multiple cities, because it keeps safety standards consistent across the entire fleet.
Maintenance dashboards and task automation
A maintenance dashboard centralises alerts, open issues, and upcoming service requirements.
With structured task management, teams can assign jobs, set priorities, track resolution times, and analyse recurring issues. ATOM Mobility’s Task Manager feature enables operators to convert alerts directly into trackable actions within one system. Alerts that turn into tasks automatically make it clear what needs fixing and when it should be handled.
From reactive to predictive maintenance
With enough historical data, fleets can move beyond fixed intervals. Operators can identify patterns such as faster brake wear in specific models or higher damage rates in certain areas. Predictive maintenance allows servicing based on actual usage intensity, reducing unnecessary costs while preventing major failures.
For operators growing from 50 to 500 vehicles, automation delivers clear advantages:
- higher uptime, because issues are detected earlier
- lower operational costs, since preventive repairs are cheaper than breakdowns
- improved safety and compliance, with no missed service intervals
- better customer experience, with fewer malfunctioning vehicles
- clearer performance metrics for management decisions
Automation supports maintenance teams with clearer priorities and better data.
Building the right automation stack
Effective rental fleet maintenance automation typically requires:
- IoT hardware
- a fleet management platform with automated alerts
- configurable service rules
- a task dashboard
- task automation logic
- analytics tools
When these components are connected, maintenance becomes scalable and controlled instead of reactive. This is especially important for operators running scooter, bike, car sharing, or rental businesses, where uptime directly impacts revenue and retention.
Rental fleet maintenance automation makes maintenance more organised and easier to manage as you grow. IoT telematics, automatic diagnostics, mileage alerts, and task dashboards help create clear processes that support expansion.
For rental and shared mobility operators who want to grow steadily, automating maintenance is essential. It helps keep operations stable and supports long-term profitability.

Lime improved GPS. But parking compliance may need more than that
Lime improved GPS from 12m to ~1.5m accuracy - a big step forward for micromobility. 🚀 But parking compliance isn’t just about knowing where a vehicle is - it’s about proving it’s parked correctly. Real-world pilots (like Prague) show that physical verification (e.g. Bluetooth beacons) can significantly outperform GPS when it comes to actual compliance.

Lime just raised the bar for GPS-based parking compliance. But the bigger question is this: when cities want verified parking, is better GPS enough, or do operators need physical proof? That question matters more than ever.
Lime’s new LimeBike rollout in the UK comes with a major location upgrade. Lime says its new bikes can locate themselves to within 1.5 metres, a significant improvement from the roughly 12.3 metres typical in dense urban environments (this means that based on GPS data, a vehicle can be up to 12 meters farther or closer than the reported GPS location. Now this error is just 1.5 meters). That is real progress.
Lime’s upgrade is a meaningful step forward for GPS-based positioning. At the same time, cities are increasingly looking beyond positioning accuracy toward verifiable parking compliance.
Why this matters
Cities are becoming much less tolerant of parking disorder. In Kensington & Chelsea, the council seized 1,000 rental e-bikes by November 2025 and collected more than £81,000 in charges from operators.
That is the real backdrop for every operator today:
- stricter enforcement
- more political pressure
- less room for ambiguity
So yes, better GPS is good news. But it does not automatically mean cities will see parking as “solved.” A vehicle may be near a bay, beside a bay, or slightly outside it. In dense urban areas, that difference matters. Traditional GPS struggles there because of building interference, blocked satellite visibility, and signal reflections.
So the strategic question is no longer:
“Can we improve GPS?”
It is:
“What kind of system gives cities enough confidence to enforce parking rules fairly and consistently?”
What the Prague pilot showed
A European Commission-backed pilot in Prague tested a different approach: Bluetooth-based parking verification.
Across 25 parking locations and 989 parking events, the results were clear:
- 90.6% success rate for SparkPark (Bluetooth infrastructure)
- 38.4% success rate for GPS/GNSS positioning
- Technology readiness advanced from TRL 6 to 8/9
When the goal is verified parking inside a defined zone, infrastructure-based validation can significantly outperform vehicle-only (GPS) positioning.
GPS improvement vs physical verification
Lime’s move shows how far vehicle-side intelligence is improving. SparkPark points to a different model: verify the parking zone itself.
That distinction matters.
- GPS estimates where the vehicle is
- Infrastructure confirms whether it is correctly parked
Those are fundamentally different approach.
Why cities may prefer the second path
One of the key findings from the Prague pilot is not just technical - it is institutional. Cities often rely on operator-provided data to assess compliance. That creates a trust gap. What cities increasingly want:
- independent verification
- reliable compliance data
- less reliance on operator-reported positioning
This is why the conversation is shifting from “better accuracy” → “verifiable proof.”
What this means for ATOM Mobility partners
Parking compliance is becoming more important than ever:
- permit approvals
- permit renewals
- daily operational performance
Operators who can demonstrate verifiable compliance may have a clear advantage.
With ATOM Mobility, partners can explore:
- integration-ready compliance workflows as ATOM Mobility already implemented bluetooth-based parking verification together with SparkPark
- futher support for infrastructure-based validation like SparkPark
- 10x faster deployment without full fleet replacement
Instead of waiting for hardware cycles, operators can move faster and adapt to changing city expectations.
Lime deserves credit for pushing GPS accuracy forward. It is a meaningful step for the industry. But the Prague pilot highlights something equally important:
Micromobility parking may not be solved by better positioning alone. It may also require verification.
Not:
“Where is the vehicle likely parked?”
But:
“Can this parking event be verified with confidence?”
Final thought?
The future of parking compliance is likely evolving across two complementary paths:
Path 1: improve GPS accuracy
Path 2: implement physical verification
The first makes parking smarter. The second makes it more reliable and verifiable.
And in regulated urban mobility, confidence and trust often matter as much as precision.
