From an innovative idea to a successful company: the story of MESI, supported by the Slovene Enterprise Fund
Date of publication: 12.11.2026
MESI, which began its development journey with an innovative idea in the field of medical diagnostics, is today an internationally established company. According to available business data for 2025, the Slovenian company MESI, d. o. o., employed 95 people and generated total revenues of EUR 10.73 million.
Its innovativeness and development potential are further confirmed by its inclusion on the FUTURE 100 Slovenia list, which highlights promising Slovenian companies with strong potential for growth, development, and international competitiveness.
The development path of MESI clearly illustrates how timely and well-directed financial support can help turn innovative business ideas into reality, enabling their successful market entry and further growth.
Watch the success story of MESI
How did support from the Slovene Enterprise Fund contribute to the development of MESI – from the first development steps to the production of innovative medical devices and further growth? Watch the company’s story in the video.
From the first employee to the development of an innovative medical product
In the early stages of development, MESI received support from SEF under the P2 – Incentives for the Start-up of Innovative Companies instrument.
This financial instrument enables SEF to support young innovative companies with non-repayable funds for developing new products, services, and business models, as well as for entering the market.
The grant enabled MESI to hire its first employee and develop an innovative medical product, representing an important step in laying the foundations for the company’s further growth.
Under the P2 call, young innovative companies can receive up to EUR 72,000 in non-repayable funds. The call is expected to be reopened in early 2027.
With the help of an SEF guarantee, toward production of the first 100 medical devices
The company reached its next major development milestone with the help of the P1 – SEF Guarantees for Bank Loans with Subsidized Interest Rate instrument.
SEF guarantees make it easier for companies to access bank loans, offering more favorable financing terms and lower collateral requirements. They are intended for financing investments that enable companies to further develop, increase production capacity, and strengthen competitiveness.
With the help of an SEF guarantee, MESI obtained a bank loan that financed the production of the first 100 medical devices.
This step was crucial for the company, as it enabled the transition from the development phase to actual production and sale of innovative medical solutions.
SEF guarantees for bank loans are expected to become available again in 2027.
From the first 100 devices to a private capital investment
The successful production and sale of the first medical devices allowed MESI to confirm its innovative solution in the market as well.
With its first sales results, the company demonstrated the market potential of its product to private investors and secured a private capital investment for further growth and development.
The example of MESI thus shows how different forms of financing can complement one another. Initial non-repayable funds enable the development of an innovation, guarantees facilitate access to production financing, and a successful market performance opens up opportunities for attracting private capital.
As MESI summarized their experience with SEF support:
“Without the support of the Slovene Enterprise Fund, it would have been difficult, if not impossible.”
SEF – supporting companies at different stages of development
At the Slovene Enterprise Fund, we recognize that companies need different forms of financial and development support at each stage of their growth.
That is why, through our financial and development instruments, we help create more favorable conditions for the establishment, development, and growth of Slovenian companies. By combining non-repayable funds, guarantees, loans, and other forms of support, we help companies overcome financial and development obstacles and realize their business potential.
The story of MESI is an example of how public financial support can foster the development of innovations, facilitate their market entry, and lay the foundations for a company’s further growth, also with the help of private capital.
Your business success story can also start with the right support
In 2027, the Slovene Enterprise Fund will continue to provide financial and development incentives for micro, small, and medium-sized enterprises.
We invite companies to follow current and upcoming public calls and check the funding options available for their development and investment projects.
