Amplify Partners Research
Overview
Amplify Partners is an early-stage venture capital firm founded in 2012 and headquartered in Menlo Park, California with offices in San Francisco. For nearly 15 years, Amplify has been the first institutional investor for the world's best technical founders, engineers, researchers, and scientists building the next generation of applications, models, tools, and infrastructure. The firm is singularly focused on backing deeply technical founders who combine exceptional engineering prowess with visionary ambitions.
Investment Philosophy & Thesis
Amplify's core thesis is centered on technical founders - the "lunatic fringe" of developers, technologists, data scientists, hackers, and practitioners who have experienced a problem viscerally and are compelled to spend the next decade solving it. The firm believes that the next generation of generational companies will be built by engineers, researchers, and scientists, not traditional business-focused entrepreneurs.
Historically, Amplify identified that we were entering the era of the technical founder when most investors were skeptical. They backed founders from Datadog and Fastly (over a decade ago when technical founders running B2B companies were considered unconventional). Today, as AI is coming for every piece of software and technology, Amplify believes technical founders are better positioned than anyone to lead this transformation.
Key aspects of Amplify's philosophy:
- Founders over Products: Amplify looks for founders who are obsessed with solving problems they themselves have experienced
- Humility & Humor: Founders who can approach the journey with empathy, humility, and humor are positioned for long-term success
- Technical Excellence: The firm invests in tools, platforms, and infrastructure that enable technical builders to move faster, safer, and cheaper
- Story Over Features: Founders must articulate not just the what, but the why and how - their strategic narrative becomes their strategy

Team & Leadership
Founders & General Partners:
Lenny Pruss, General Partner - Lenny immigrated to the US from the Soviet Union as a refugee and grew up in Silicon Valley during the Dotcom boom. He studied EECS at UC Berkeley and discovered venture capital as his path to exploring the future. He started his VC career in New York during the social/mobile boom but became interested in developer tools and infrastructure. He worked with generational founders at companies like Datadog, Hashicorp, and Cockroach Labs before joining Amplify. Lenny looks for founders in the "lunatic fringe" - those obsessed with solving problems only they can build solutions for.
Mike Dauber, General Partner - Mike grew up outside Washington, D.C. and was an electronics enthusiast who majored in Electrical Engineering at University of Michigan. After two years as a hardware engineer, he transitioned to product, sales, solutions engineering, and marketing roles. He became a VC in 2008 at Battery Ventures before helping co-found Amplify in 2014. Mike focuses on founders who are deeply steeped in their domain, have something to prove, and are borderline obsessed with their ideas.
Sarah Catanzaro, General Partner - Sarah grew up in New York doing scientific experimentation. She studied mathematics and natural sciences, then attended Stanford where she discovered quantitative analysis of security and terrorism. She worked at the Center for Advanced Defense Studies applying AI to security, joined Qinetiq and Palantir, then worked on data intelligence at Mattermark. Sarah invests in tools that enable data-driven decision making and works with founders obsessed with using technology to solve critical problems.
Sunil Dhaliwal, General Partner - Co-founder of Amplify, Sunil helped build the firm from inception.

Summary
Amplify Partners represents a rare venture capital firm entirely focused on technical founder success. Founded in 2012 and led by General Partners Lenny Pruss, Mike Dauber, Sarah Catanzaro, and Sunil Dhaliwal, with support from Partners Barr Yaron, David Beyer, Elliot Hershberg, and Grace Ge, the firm has backed some of the most successful technical companies of the past decade including Datadog, Fastly, Temporal, dbt, Runway, Modal, Luma, and Chainguard.
With $900M in new capital across three funds (Fund 6, Fund 6 Select, and Amplify Bio) announced in June 2025, the firm is actively deploying capital into seed and Series A founders building the next generation of developer tools, infrastructure, data systems, AI/ML platforms, and biotech innovations.

Amplify is ideal for technical founders with clear visions, strong execution abilities, and the ambition to build category-defining companies.
