Maximilian Viessmann inherited a fourth-generation industrial platform, then led its digital transition and the sale of Viessmann Climate Solutions to Carrier while keeping the family invested in the buyer and redeploying capital through the remaining group. [1][2][3][4]
He entered an established fourth-generation family company
Viessmann's family history identifies Maximilian as the fourth generation of a company founded in 1917, so his starting position included an established industrial business rather than a company he built from scratch. [1]
Before joining the family company, he worked at Boston Consulting Group and invested in startups; he joined Viessmann in 2015 to lead its digital transformation and became co-CEO in 2017. [1]
He later took responsibility for the group's largest business area and became sole CEO in 2022, giving him several years of operating authority before the transaction that reshaped the family's balance sheet. [1]
The Carrier transaction converted a mature operating asset into cash and public equity
In 2023 the family agreed to sell Viessmann Climate Solutions to Carrier for about €12 billion, with Carrier paying 80% of the consideration in cash and 20% in stock; the family said it would reinvest the primary proceeds through the remaining Viessmann Group. [3][2]
A May 2026 SEC filing shows how that value continued to evolve: Viessmann's holding company sold 12,094,823 Carrier shares at $62.01 each while retaining 37,979,286 shares, or about 4.57% of Carrier. Max remained a Carrier director, leaving the family with both realized liquidity and continuing public-company exposure. [4]
