session.vc
session.vc was founded by entrepreneurs Martin Altorfer, Philippe Bubb, and Jeremias Meier, who together have more than three decades of company-building experience and several exits — including two unicorns. Altorfer previously founded Active-Net (sold to UUNET) and Celeris (sold to Swisscom); Meier co-founded the SaaS accounting platform Bexio and led it to a sale to Mobiliar in 2018, where Altorfer served as Executive Chairman. The firm operates from Switzerland and invests the partners' own capital. The firm targets tech-enabled growth companies that have demonstrated product-market fit without relying on continuous fundraising. It pursues early-stage and growth investments, primarily in enterprise software and SaaS, with a geographic focus on Europe. The three partners take an owner-operator approach, committing time and capital, and do not shy away from taking on temporary executive roles. Confirmed portfolio activity includes Bexio, the Swiss SaaS accounting business sold to Mobiliar in 2018. session.vc is run solely by its three co-founders, who act as hands-on operators alongside their investment activity. The firm's model centers on direct involvement in scaling operations, data-driven marketing, and sales execution for the companies it backs. No additional offices, team members, or adjacent vehicles have been disclosed. What distinguishes session.vc is its structure as a pure operator-investor: the three partners invest their own capital and step directly into portfolio companies as temporary executives. This blurs the line between a traditional VC and an operating partner model, making the firm resemble an embedded founder-operator team rather than a passive fund manager.

Frequently asked questions
Who runs investment decisions at session.vc?
Investment decisions are made by the three co-founders: Martin Altorfer, Philippe Bubb, and Jeremias Meier. Each brings decades of operator experience — Altorfer in IT infrastructure and product, Bubb in consumer and brand strategy, and Meier in SaaS and data-driven marketing. There are no external investment committee members or junior partners; all three are active in deal sourcing and portfolio support.
How does session.vc source proprietary deal flow?
The firm relies entirely on the personal networks of its three co-founders, who have spent decades building and exiting technology companies in Europe. Their track record includes two unicorns and multiple exits to strategic buyers such as Swisscom and Mobiliar, which gives them direct access to founders and management teams in the Swiss and broader European tech ecosystem.
Is session.vc structured as a family office or does it operate more like a venture firm?
session.vc is a partnership of three serial entrepreneurs deploying their own capital, rather than a family office or a traditional venture firm with external limited partners. It does not raise funds from outside investors. The firm more closely resembles an operator-led investment vehicle than a classic VC, given the partners' willingness to take temporary executive roles at portfolio companies.
Does session.vc participate in fund commitments or only direct deals?
All known activity points to direct investments only. The firm describes itself as committing 'time and capital' directly into companies, with no disclosure of fund-of-fund commitments or LP positions in other venture funds. The operator-investor model would be inconsistent with passive fund commitments.
What investment stages does session.vc typically target?
The firm invests in tech-enabled growth companies that have already demonstrated product-market fit and do not rely on continuous fundraising. This suggests a focus on late-seed to growth-stage companies, specifically those that are post-revenue and scaling operations.
Which sectors does session.vc explicitly avoid?
No explicit avoidance is disclosed. However, the partners' backgrounds and stated focus on tech-enabled growth companies suggest a concentration in enterprise software and SaaS. The firm is unlikely to invest in sectors where hands-on operational involvement is impractical — such as biotech, deep hardware, or capital-intensive infrastructure.
Where does the underlying capital come from?
The capital is the three co-founders' own wealth, generated from founding and exiting multiple technology companies. The known exits include Active-Net to UUNET, Celeris to Swisscom, and Bexio to Mobiliar. The firm does not accept outside capital.
