Rainmaker has agreed to buy all shares in Yellow Holding, owner of B2B sales outsourcer Inhouse Group, and is investigating a listing on Nasdaq First North Growth Market Finland. The Finnish sales and customer service outsourcer had 2025 turnover of EUR 45.9 million.
Rainmaker buys Inhouse to close the gap on its EUR 7 million B2B target
Rainmaker aims to grow its B2B business to around EUR 7 million by the end of its 2025 to 2027 strategy period. B2B sales revenue was EUR 1.6 million in the first half, up from EUR 1.0 million. Two pilot assignments did not move into production, and volumes in its SDR service fell in spring before recovering in early summer. Inhouse covers prospecting, customer acquisition and appointment booking, and will keep its own brand. The purchase price was not disclosed.
“Inhouse Group has built a strong position in demanding B2B solution sales and developed operating models that perfectly complement Rainmaker's business entity. The acquisition supports our strategy to grow and strengthens our position as a growth partner for our customers,” says Tapio Korttilalli, CEO of Rainmaker, in the press release.
Inhouse follows two acquisitions in the first half of 2026
In February, Rainmaker bought telephone sales company Myyntimestarit and its roughly 60 sales professionals. It also bought Digizer's e-commerce customer service business. First-half revenue rose 14.2% to EUR 24.6 million, with organic growth of 10.6% and acquisitions adding 3.6 percentage points. Comparable EBITDA rose to EUR 1.7 million, or 7.0% of revenue, the bottom of its 7 to 10% medium-term target range.
The balance sheet has been rebuilt for a listing since spring
In June, pension insurer Veritas subscribed EUR 2.0 million of new shares, equal to 11.76% of shares after registration. “The company's growth prospects and market position create a solid foundation for the company's future development and it is really great to be part of this story,” says Theo Laakso, portfolio manager at Veritas.
Interest-bearing net debt fell to EUR 5.6 million from EUR 9.7 million a year earlier, or 1.5 times rolling EBITDA. In July, several loan arrangements were replaced with a single long-term facility with fewer covenants.
Two holding companies own more than 90% of the shares
Before the Veritas shares were registered, GTW Group held 58.56% of Rainmaker and Divest Group 34.34%. The company says a listing would strengthen its capital structure and fund organic and acquisition-driven growth. A new company form, an outside equity investor and simpler debt all point the same way. The Inhouse deal gives prospective investors a first look at what a listing would pay for.
