Summit Partners has reinvested in Finnish supply chain software company Relex.

The deal comes two years after Summit first backed the company, investing €20m for a minority stake. Following this latest round Relex’s founders remain majority shareholders and in senior leadership positions.

Relex’s software enables customers to improve their operational efficiency by unifying merchandising, supply chain and store operations.

Since Summit’s first investment the company has almost tripled revenues, entered the North American market and added new customers including WH Smith, Morrisons and AO.com. It has also acquired space optimisation software company Galleria RTS and invested in workforce software company Zenopt.
