Sovendus Acquires 35up and Strengthens Data-Driven Cross-Selling Capabilities in eCommerce

Sovendus GmbH has acquired 35up, a specialized provider of intelligent cross- and upselling technology for eCommerce. Through this transaction, the founders and investors of 35up have achieved a successful exit after building one of Europe’s leading technology providers for data-driven cross-selling in online retail.

The parties have agreed not to disclose the financial details of the transaction.

Founded in 2021 by Klaus Wegener, Fabian Louis, and Victor Schröder, 35up has established itself within just a few years as a high-performance platform for revenue optimization in eCommerce. With a clear focus on measurable performance, scalable technology, and rapid integration into existing shop systems, the company has successfully positioned itself in the market.

At the core of the platform is a data-driven cross-selling algorithm that optimizes product recommendations in real time, significantly increasing conversion rates, average order value, and customer lifetime value. The technology has already been successfully deployed across various eCommerce environments and continuously refined.

35up’s investors include Capnamic, Coparion, and Dieter von Holtzbrinck Ventures – renowned European technology investors that have supported the company’s growth and strategic development. In addition, business angels such as Gert Purkert, Kersten Jodexnis, Andreas Burike, Daniel Arnold, and the family office hochquer have provided both financial and operational support.

With Sovendus, 35up is joining a strategic buyer with exceptional reach across the European eCommerce landscape. Sovendus is integrated into thousands of online shops and operates an established partner network, providing ideal conditions for scaling the 35up technology.

Quote / Sebastian Legler, Managing Director of Sovendus GmbH

35up has built a technologically outstanding solution for cross-selling and performance optimization. What convinced us was precisely this combination of algorithmic excellence and a clear focus on measurable results. Together, we see significant potential to roll out this technology across our network at scale.

For Sovendus, the acquisition represents a targeted expansion of its value creation capabilities in the area of data-driven revenue optimization. For 35up, the sale to a strategic partner with this level of market penetration marks the next logical step in scaling its technology to significantly greater volumes.

Quote / Klaus Wegener, Co-Founder and CEO of 35up

We built 35up with the ambition of creating real, measurable value in eCommerce. Bringing this technology into an environment with such extraordinary reach is the ideal next step. At the same time, it is a special moment to see such an established and impressive company as Sovendus recognize the value of our technology and strategically integrate it into its vision.

As part of the agreement, Klaus Wegener will remain involved with Sovendus as an advisor and will support the strategic development of the cross-selling technology.

The transaction has been completed with immediate effect.
