Investment thesis

Venturehouse Group takes a long-term approach to private equity financing, operating as a holding company rather than a traditional fund. Beyond deploying its own capital into young private companies, the firm positions itself as a strategic partner, offering expertise, infrastructure (including office space), world-class advisers, capital-market relationships and preferred service-provider connections. This support network is intended to shorten the entrepreneurial learning curve and improve a company's odds of success. Rooted in the Washington, DC technology community while maintaining worldwide relationships, the firm builds its own company and then uses its resources to create and grow successful businesses across a diverse range of industries.
