Spark Capital

What Spark Capital does

Spark Capital Partners, LLC is a privately held, independent venture capital firm headquartered in Boston, Massachusetts (200 Clarendon Street, Floor 59, Boston, MA 02116), founded in 2005 by Santo Politi, Todd Dagres, and Bijan Sabet with an inaugural $250 million fund. As of early 2026 the firm manages more than $4 billion in assets under management and is raising approximately $3 billion in new funds, ~50% larger than its prior raise per The Information. Spark maintains three U.S. offices — Boston (headquarters), New York City, and San Francisco (opened in 2012 by Nabeel Hyatt) — and operates two investing teams: an Early-stage team (Mikowai Ashwill, Alex Finkelstein, Fraser Kelton, Natalie Vais, Santo Politi) and a Growth-stage team (Clay Fisher, James Kuklinski, Jeremy Philips, Yasmin Razavi, Will Reed), with corporate functions led by CFO Alexa Lyons, General Counsel Diana Berisha (the firm's first, hired in 2023), Controller Sarah Kimball, and Head of Investor Relations Jeff Doran.

The firm invests across five stated sectors — Consumer, Enterprise, AI, Frontier Tech, and Fintech — at stages from seed/Series A through Series B/C and beyond, often leading rounds and taking board seats. Notable lead investments include Twitter's Series B (2008), Cruise's Series A (2015, sold to GM for $1B+), Discord's Series C (2016), Plaid's seed, Anthropic (first VC in 2023; $450M at a $5B valuation, stake now worth $3B+ as Anthropic approaches ~$900B), Mercury (Series D, May 2026), Baseten ($1.5B Series F, June 2026), Cadence ($100M Series C, June 2026), Ada ($130M Series C at $1.2B, February 2026), and Standard Intelligence ($75M co-led with Sequoia, May 2026). The portfolio is unusually operator-heavy at the partnership level — Fraser Kelton (former Head of Product at OpenAI), Nabeel Hyatt (co-founded Conduit Labs, acquired by Zynga), Kevin Thau (former Twitter product and BD lead), and Jeremy Philips (co-founded ecorp, IPO'd; former EVP at News Corp) — and Spark markets itself as hands-on, design-aware, and willing to back unconventional founders outside pattern-matching playbooks.

Spark Capital does not sell a software or technology product of its own; revenue is generated through standard venture fund economics — management fees on assets under management plus carried interest on investment gains. The firm markets primarily through long-form founder storytelling (its "Creator Stories" content), partner-hosted podcasts (Nabeel Hyatt's "Hallway Chat"), Forbes Midas List–anchored earned media (Razavi No. 13 in 2026), partner activity on X/Twitter, and dedicated LP outreach via Jeff Doran. Pricing/fees are not publicly disclosed and are negotiated privately with Limited Partners.
