About

Hummer Winblad Venture Partners (HWVP) is a San Francisco-based venture capital firm founded in 1989 by Ann Winblad and John Hummer 12. The firm pioneered the concept of a venture capital fund investing exclusively in software companies, making it the first VC firm with an all-software focus 13. Ann Winblad, a former systems programmer at the Federal Reserve Bank of Minneapolis and co-founder of accounting software company Open Systems Inc. (sold in 1983), partnered with John Hummer, a former first-round NBA draft pick who played six seasons in the league before earning his MBA at Stanford in 1980 345.

Raising the initial fund took nearly two years and 134 meetings, with IBM and The St. Paul Companies among the primary early investors 6. In 1999, Bill Gates invested in the firm’s venture fund 1. Over its 30-plus-year history, HWVP has managed over $1 billion in cumulative capital across multiple funds and launched over 160 enterprise software companies 23. Notable fund sizes include Fund V at $424 million (2000), Fund VI at $201 million (late 2007), and Fund VII which targeted $105-150 million 7.

In 2015, the firm rebranded from “Hummer Winblad Venture Partners” to “HWVP” 7. In 2016, for the first time, the firm raised a fund without Ann Winblad or John Hummer listed among the general partners, signaling a generational transition 17. In July 2021, HWVP announced the closing of a $70 million fund and a rebrand to Aspenwood Ventures, led by Managing Directors Lars Leckie and Steve Kishi 89. Ann Winblad transitioned to Partner Emeritus, serving as an advisor 9.

The firm is headquartered at 338 Spear Street, Suite 42E, San Francisco, CA 94105 2.

Stated Thesis

HWVP publicly describes itself as focused on “early-stage enterprise software companies” and characterizes its team as having “deep operation understanding in every aspect of company building, from the early stage product development to the challenges of rapidly scaling to meet demand” 2. The firm states its team consists of “technology forward thinkers and engineers” who have “been in the trenches themselves” 2.

Ann Winblad has described the firm’s focus as “all business to business opportunities, primarily those that are aimed at the enterprise. At the enterprise, we have two levels. There’s the core software infrastructure that includes development tools, data center infrastructure, integration, and security. On top of that, we’ve always been investors in analytics” 10.

Lars Leckie has stated that “it is a very good time to quietly invest in enterprise and SaaS infrastructure” and that “small, focused funds do the best by their investors,” suggesting “$35 million to $50 million per partner is ideal” 7.

Steve Kishi has characterized the firm’s focus as “early-stage investments in enterprise software applications and infrastructure” leveraging deep knowledge of “SaaS and virtualization technologies” 11.

Inferred Thesis

Based on 28 verified portfolio investments, HWVP’s actual investment behavior closely matches its stated thesis of exclusive enterprise software focus, with some notable patterns:

Sector breakdown (28 verified investments): - Enterprise applications / SaaS platforms: 10 of 28 (36%) — MuleSoft, Five9, InsideSales, Extensity, Aria Systems, Birst, Employease, Oomnitza, StepFunction, Stackery - Infrastructure / virtualization / cloud: 8 of 28 (29%) — PLUMgrid, vKernel, Pancetera, Akimbi Systems, Altiscale, NetDynamics, Wavemaker, Scalent - Analytics / business intelligence: 4 of 28 (14%) — Omniture, Arbor Software/Hyperion, OptiMine, Ace Metrix - Developer tools / DevOps: 3 of 28 (11%) — Powersoft, Sonatype, Wind River Systems - Consumer internet / media: 3 of 28 (11%) — Napster, The Knot, Liquid Audio

Stage distribution: Overwhelmingly early stage. The firm has consistently led seed and Series A rounds, frequently as the first institutional investor. Notable first-investor roles include MuleSoft (two-person startup), Five9, InsideSales, Aria Systems, and Birst 127.

Check size: $500K to $3M, with a sweet spot around $2M for initial investments 13.

Geographic focus: Predominantly US-based companies, with some willingness to invest globally. MuleSoft’s CEO was originally based in Malta, and Lars Leckie has noted the firm “sources ventures globally” 10.

Outcomes: The portfolio shows a high rate of successful exits. Of the 28 verified investments: 7 IPOs (Powersoft, Arbor/Hyperion, Liquid Audio, Extensity, Omniture, Five9, MuleSoft), at least 8 acquisitions by major technology companies (Sun Microsystems, Sybase, Intel, VMware, Quest Software, Quantum, Microsoft, Oracle, Dell, Barracuda Networks), and 1 notable failure (Napster) 1214.

Notable gaps: Despite claiming an exclusive software focus, the firm made a few consumer internet bets during the dot-com era (Napster at $15 million, The Knot, Liquid Audio) that diverged from the enterprise thesis 115. Post-2005, the portfolio shows a much tighter enterprise-only focus.

Co-investor patterns: The firm has co-invested with U.S. Venture Partners (InsideSales), NEA and Salesforce Ventures (MuleSoft), SAP Ventures (MuleSoft), C5 Capital (Oomnitza), and Voyager Capital (Stackery) 71617.
