Tempo Ventures

Dennis Phelps, Tempo's founder and General Partner, leads investment decisions with a compact partnership group. Phelps' background spans Silicon Valley Bank and Institutional Venture Partners, which shaped the firm's institutional discipline in early-stage investing. The small partnership structure enables rapid decision-making without committee bottlenecks.

Tempo deliberately limits each fund to roughly 20 portfolio companies, far fewer than most seed-stage peers who index across 40 to 60 startups. This concentration strategy targets higher ownership stakes and deeper engagement with each founding team. The firm reserves significant follow-on capital for breakout performers, creating a barbell approach that pairs conviction-led seed bets with concentrated follow-on deployment.

Tempo invests in enterprise software, applied AI and machine learning, digital health, fintech infrastructure, and robotics. The firm gravitates toward technical founding teams building B2B products rather than consumer-facing applications. Within enterprise software, Tempo has demonstrated particular interest in API-first companies, developer tools, and data infrastructure.

Tempo typically leads or co-leads seed rounds, taking an active governance role through board seats or observer rights. The firm collaborates regularly with other seed-stage funds and occasionally partners with multi-stage firms on follow-on rounds. This lead-investor posture reflects the concentrated portfolio model, which requires high-conviction underwriting rather than passive check-writing.

Tempo's primary geographic focus is North America, with particular concentration in San Francisco, New York, and emerging tech hubs across the United States and Canada. The firm evaluates European seed opportunities selectively when the founding team has strong ties to Tempo's network or when the company has early traction in North American markets.

The firm reserves significant capital within each fund for follow-on participation in breakout companies. This structure commits Tempo to supporting portfolio companies through Series A and beyond, rather than the spray-and-pray model common among seed funds that write many small checks and reserve little for later rounds. The concentrated portfolio size makes meaningful follow-on capacity feasible per fund.

Tempo regularly co-invests alongside other seed-stage and multi-stage venture firms, particularly those with complementary enterprise or deep-tech expertise. As a lead investor, Tempo often syndicates rounds to bring strategic value beyond capital. The firm does not operate a formal co-investor club or LP co-investment program based on public disclosures.
