KEEYNS Secures €10M investment to fuel rapid expansion

With a growing number of international customers, Keeyns is preparing to roll out their tax collaboration platform in other European countries and the USA.

Den Bosch-based Keeyns has successfully secured €10M in fresh funding, setting the stage for its ambitious expansion into Europe and the United States. As a plug-and-play collaboration platform, Keeyns revolutionizes how tax teams interact with internal and external stakeholders. It enables customers to set up a centralized tax data warehouse, tailor workflows to their specific needs, ensuring deadlines for tax filings and payments are met effortlessly around the globe.

“This funding is a strong endorsement of our mission and the dedication of our team. It sets the stage for our continued success in the Netherlands and paves the way for introducing our innovative tax collaboration platform to Europe and the United States,” says Ruben van Aarle, CEO of Keeyns.

With this investment, Keeyns will develop specialized tax engines for different tax areas. These engines will automate tax preparations and tax reporting, making it easier and more efficient. Additionally, Keeyns will be expanding their tax tech stack, looking into more areas for digital enhancement. Van Aarle adds, “Our goal is to progressively blend artificial intelligence into the platform. This leap forward will fuse business operations with being in control and compliant while making tax planning more seamlessly, enabling decision-makers to act more swiftly, economically, and with greater confidence by exploring different scenarios.”

In this funding round, Keeyns proudly announces support from Alea Capital Partners, an esteemed private equity investor in Portugal and Mountainview Capital Partners, a Dutch investment firm run by seasoned entrepreneurs. Selecting Portugal as a second location was a strategic decision, influenced by the nation’s supportive stance on R&D and competitive human capital. Portuguese technology universities are pivotal to the development of the platform, enhancing the efforts of the company with their expertise and facilitating nearshoring benefits. While Keeyns was already set on leveraging these advantages, the participation of Alea Capital Partners has significantly accelerated these plans.

Mark van der Biezen, Partner at Mountainview Capital Partners adds: “We have known the founders and management team for several years now and are impressed with the product they have built with their team. Keeyns is a leading software company that has shown impressive growth in recent years, with ample growth opportunities due to the ever-increasing complexity of taxation. Whereas some products are nice to have, we have seen that tax professionals all around the world regard Keeyns’ solution as a must have. We are therefore exited to be partnering with the entrepreneurial team at Keeyns in their next phase of growth.”
