Everything you need to know before starting your car-sharing business

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.

ATOM Mobility API: Build your own mobility experience on top of a proven platform

⚡ Launch faster and integrate anywhere with ATOM Mobility API. Build your own mobility experience without rebuilding the backend. Learn how ATOM Mobility API lets you integrate, customize, and scale faster.

Read post

Shared mobility is moving beyond standalone apps. Operators today are expected to integrate into existing ecosystems - from hotel and airport platforms to corporate travel tools and MaaS apps. Building all of that from scratch is slow, expensive, and hard to scale.

That’s why ATOM Mobility offers a fully developed OpenAPI - allowing you to build your own mobility experience on top of a proven backend.

From app to platform

Most mobility solutions are still built as closed systems. That creates friction: integrations take time, custom features require heavy development, and expanding into new channels becomes complicated.

An API-first approach changes this.
Instead of rebuilding core functionality, operators can use ATOM Mobility as the underlying system and build their own layer on top. Booking flows, payments, vehicle control, and operational logic are already there - accessible via API.

What this enables in practice

With API access, mobility can be embedded directly where users already are.

- A ride can be booked from a hotel website. A car can be unlocked through a partner app. A custom frontend can be built for a specific market without touching the backend.

- At the same time, operators can connect their own tools: from internal dashboards to finance and reporting systems (for example, Power BI) creating a more automated and scalable operation.

The result is not just a mobility app, but a flexible system that can adapt to different markets, partners, and use cases.

What you can manage with ATOM Mobility API

🚗 Booking & ride management - search vehicles, reserve and unlock, start and end trips, manage ride status.

💳 Payments & users - create and manage users, handle payments and pricing, access booking history.

🛴 Fleet & operations - vehicle status and location, zones and restrictions, pricing configuration.

🔌 Integrations - connect third-party apps, sync with external systems, automate workflows and more...

Few use cases we already see

1. Embedded mobility in partner platforms

Booking directly from (no app download needed):

  • hotel websites
  • airport kiosks
  • corporate travel portals
  • MAAS apps (such as Umob)

2. Custom frontends and apps

Operators build:

  • branded web apps
  • niche UX flows
  • country-specific experiences

All powered by ATOM Mobility backend.

3. IoT and hardware integrations

  • sync vehicle data
  • control locking/unlocking

4. Automation & internal tools

  • reporting dashboards
  • finance automation
  • customer communication flows

Instead of spending months building core systems, operators can use ATOM API and focus on what actually drives growth - distribution and partnerships.

How to fully automate maintenance tasks and alerts for rental fleets
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
Task management app by ATOM Mobility

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.
