What Symphony Technology Group does

Symphony Technology Group (STG) is a private equity firm founded in 2002 and headquartered in Menlo Park, California, that invests in and builds mid-market enterprise software and software-enabled technology services companies. The firm operates two primary strategies: a flagship mid-market strategy targeting companies with enterprise value between $100 million and $1 billion, and the Allegro strategy, which focuses on lower mid-market investments typically under $500 million. As of March 2025, STG manages over $12 billion in assets under management and has raised nearly $14 billion across all funds, with 140+ completed investments across 60+ portfolio companies spanning verticals including cybersecurity, GRC/compliance, financial services, retail, construction, media/entertainment, healthcare, and government.

STG's portfolio includes notable software companies such as SurveyMonkey, Avid Technology, Trellix, Wrike, SAI360, Yodlee, Skyhigh Security, eProductivity Software, Quoreka, Celtra, Movable Ink, Confience, and Nomis. The firm maintains a wholly-owned operational subsidiary, STG Labs, based in a 19,000 sq ft facility in Bangalore, India, which provides portfolio companies with offshore engineering, AI/ML, data science, professional services, and support delivery teams. STG also differentiates through dedicated Operating Partners leading go-to-market transformations, technology/cybersecurity maturation, and a centralized Head of Talent function managing CEO and senior leader placement across the portfolio.

STG generates revenue through two primary streams: management fees (typically 1-2% of committed or invested capital) on its private equity funds, and carried interest on profits from successful portfolio exits. The firm distributes capital through institutional limited partners including public and corporate pension funds, insurance companies, endowments, foundations, family offices, and asset managers globally. Deal sourcing is conducted by a dedicated business development team of Managing Directors, Principals, Associates, and Vice Presidents through relationships with investment bankers, financial intermediaries, and direct outreach to founders and management teams, with the European team (anchored in London since 2024) and U.S. teams covering transatlantic deal flow.
