## About

Inbox Capital was founded in 1985 by John Wattin in Stockholm. The family office manages capital that originated from the sale of Enator AB and an early stake in MySQL. Martin Wattin, the founder’s son, served as CEO from 2015 to 2023 before becoming Executive Chairman. The firm invests in FinTech, Digital Health, Enterprise Software, Gaming, and PropTech. It deploys capital through direct equity, SPVs, and co-investments at stages from Pre-Seed to Series B. Confirmed positions include Vinted, Revolut, Truecaller, VOI, and Acast. Geographic reach centers on Sweden and the broader Nordic region while extending to the UK and other European markets. Bonnier Ventures appears repeatedly as a co-investment partner. Inbox Capital employs a compact team that includes CEO Markus, who joined in 2019 after roles at Bonnier Ventures, and analyst Ludvig, who arrived in 2024 from PwC Strategy&. The office holds commercial real-estate assets such as 24Storage and Exerton in Stockholm. January 2024: Ludvig joined Inbox Capital to cover private and public equity investments. Martin Wattin also participates in Nordic Angels as a founding member. The office’s structure keeps investment decisions inside the family while maintaining operational separation from the underlying wealth sources. This setup allows direct participation in founder-led rounds without external fund commitments or limited-partner obligations.
