Company Background

GoMore is Denmark’s largest peer-to-peer car sharing operator, that also provides a leasing and ride sharing platform. They started in 2005 and are now active in multiple European countries including Sweden, Spain, Finland, Switzerland, and Austria.

Initially, GoMore’s rental process was manual. Car owners and renters had to meet in person to document the vehicle’s condition and exchange keys. When the vehicle was returned, this process was repeated. Coordinating these meetings was time-consuming for both parties involved and made sharing a private vehicle less attractive for the owner.

To resolve this, GoMore chose the vehicle-agnostic INVERS CloudBoxx to enable keyless access to all vehicles. Renters could walk up to the vehicle, open it with their phone, and get driving in seconds. Meanwhile, hosts could earn money with their vehicles without having to fit in-person meetings into their schedule.

Removing the need for key exchanges simplified peer-to-peer car sharing for everyone.

Today, GoMore operates a fleet of about 6,000 keyless vehicles, maintaining a strong focus on customer experience and operational excellence.

Problem

While the CloudBoxx successfully enables keyless access for many vehicles, the nature of a P2P platform means users and car owners frequently onboard and offboard. GoMore was looking to improve the owner’s experience by complementing this solution with new technologies, such as vehicles with native connectivity that can be shared using the manufacturer’s API.

They initially experimented with a reverse-engineered Tesla API integration. Before Tesla rolled out its official Fleet API at the beginning of 2025, an unofficial “Owner API” like this was the only available way to integrate Teslas without hardware. This approach provided valuable insights but also revealed some limitations. In particular, it was not yet possible to integrate leased Teslas, which covers a large part of GoMore’s potential customer base. These learnings strengthened GoMore’s focus on finding a faster, more scalable integration method without the need for additional hardware installation.

Solution

After Tesla released its API in February 2025, INVERS, knowing the pain points of GoMore, worked in close collaboration with the operator to rapidly build a stable integration of the official Tesla API for their peer-to-peer car sharing. Since the Tesla API was not originally designed for sharing use cases, INVERS had to make it sharing-ready by building the necessary logic and systems to handle the demanding and unique use case of car sharing operations. This integration required strong technical support and was completed in only a few months.

The new integration now provides several key benefits that, together, reduce the complexity for operators:

• Simple onboarding process: log in via GoMore’s app, link Tesla account, and the car is ready in minutes
• Efficient wake-up calls to guarantee instant rentals for optimal customer experience
• Simplified pricing and improved operational workflows
• Scalability potential with no additional hardware needed

INVERS OEM Integrations matches perfectly with peer-to-peer car sharing, where ease of setup is critical. GoMore described the transition to the Tesla API as remarkably fast and easy:

It reinforced our confidence in INVERS as a partner who can make any vehicle sharing-ready via CloudBoxx or via OEM API the moment they hit the market.

Implementation

GoMore only had to make minor adjustments to their existing INVERS integration to accommodate the Tesla solution. With guidance and documentation provided by INVERS, the operator completed the integration in just one week. Once integrated, the process from a user logging in to the vehicle being fully available for renters was straightforward.

It only took 11 minutes until the first Tesla was available for renters.

Results

With INVERS OEM Integrations, GoMore has one single tech source for their CloudBoxx and Tesla fleet. Everything is on the same platform, so rentals work the same while data is in the same format and in a centralized place. In the first weeks of the integration being live, over 80 Teslas were already added to GoMore’s fleet.

Customers and owners now benefit from stable connectivity for both owned and leased Teslas. With zero downtime during rollout, GoMore achieved faster onboarding and drastically reduced operational friction for Tesla owners. This offers huge scaling potential for the Danish operator.

The cooperation with GoMore is a highly successful partnership, resulting in an easy-to-implement, scalable, and impactful Tesla-integration that doesn’t require extra hardware. We are happy to be part of this success story that represents a technological breakthrough for the entire car sharing industry. At INVERS, we’re ready to integrate more brands as soon as other OEMs follow Tesla’s lead.
