Matt Humphrey

Background

Matt Humphrey is a Co-Founder and Managing Partner at Quiet Capital, a venture capital firm based in San Francisco that manages approximately $2.5 billion in regulatory assets under management ¹². He joined Quiet Capital as a co-founder in January 2021 ³⁴.

Humphrey is a serial entrepreneur who has co-founded eight technology startups since 2004 ⁵⁶. He grew up in Pittsburgh, Pennsylvania, and began taking computer science courses at Carnegie Mellon University at age 13, attending classes in the afternoons while still enrolled in middle school ⁷⁸. He left high school at 17 to enroll full-time at CMU, earning a B.S. in Computer Science from the School of Computer Science in 2007 and an MBA from the Tepper School of Business in 2008 ⁷⁸⁹.

While at CMU, Humphrey co-founded Eivod, an in-browser peer-to-peer video delivery platform, which became the first Project Olympus PROBE initiative and received Y Combinator funding (S07 batch) ⁷¹⁰. The company later pivoted to SlapVid, a streaming media platform ¹⁰. He also worked at Microsoft and Rearden Commerce early in his career ¹⁰.

In January 2010, Humphrey founded HomeRun, an e-commerce platform connecting small businesses with customers seeking local services. The company powered offers programs for major brands including JP Morgan Chase, American Express, and Yellowpages.com, growing to over 80 employees with millions in revenue ⁷. HomeRun was acquired in 2011 for what Humphrey described as “just north of $100 million,” less than 18 months after launch ⁷¹¹. He remained with the company for two years post-acquisition ⁷.

After the HomeRun exit, Humphrey grew an angel investment portfolio to approximately 60 companies ⁷. In late 2013, he co-founded LendingHome (now Kiavi), an end-to-end online mortgage lending platform focused on residential real estate investors ⁷¹². Under his leadership as CEO, LendingHome grew to over 250 employees, raised over $100 million in venture capital from backers including Foundation Capital and Ribbit Capital, and originated over $6 billion in loans with approximately $100 million in annual revenue ⁴⁸¹³. Humphrey stepped down as CEO in December 2020, transitioning to a board seat, and joined Quiet Capital the following month ¹²³.

Humphrey was named to the Forbes 30 Under 30 list in the Finance category in 2017 ⁹¹⁴. He also serves as a mentor at AlphaLab, a Pittsburgh-based startup accelerator ¹⁵.

Stated Thesis

Humphrey has described his investment philosophy as rooted in his operator background, stating that he has a love for “attacking problems no matter where they may be where tech can really truly create an advantage” ⁵. His approach favors rapid iteration: “I took a philosophy of just start things, learn, rapid pace, rapid prototype, get products to market and if we’re going to succeed, great and if we’re going to fail, let’s fail fast, learn and iterate” ⁵.

VCSheet lists his investment focus as spanning AI, fintech, deeptech/hardware, health, and consumer sectors, with check sizes ranging from $100K to $25M across pre-seed, seed, and Series A stages ¹.

His talent evaluation approach has been noted in the venture community; VCSheet describes him as employing “specific questioning techniques and reference-checking methodologies” that were highlighted in First Round Capital’s investor resources ¹.

At the firm level, Quiet Capital positions itself as “builders who invest in remarkable founders from day zero,” with the tagline “Signal above noise” ¹⁶. Humphrey co-leads Quiet Capital’s Venture Capital Investment Committee alongside Lee Linden and Ben Mahdavi ³.

Inferred Thesis

Humphrey’s personal investment track record spans both his extensive pre-Quiet Capital angel portfolio and his work at the firm. Based on 11 independently verified personal investments (from CB Insights) plus his role co-leading Quiet Capital’s investment committee (which has made 124+ investments per Tracxn), the following patterns emerge ¹⁷¹⁸:

Stage distribution: Humphrey invests primarily at the seed stage. Of his 11 CB Insights-tracked personal investments, the identified rounds include 2 seed rounds, 1 Series A, and several where stage data is not publicly available ¹⁷. At the firm level, Quiet Capital skews seed-heavy: 65 of 124 Tracxn-tracked investments (52%) are seed stage, with 32 (26%) at Series A ¹⁸.

Sector concentration: Humphrey’s verified personal investments cluster in fintech (Gusto, Hippo, Mercury, Flexport, Proxifile, FinRise) and healthcare AI (Assort Health) ¹⁷¹⁹²⁰. His background as a fintech founder (LendingHome) correlates with a strong fintech tilt in his personal angel portfolio. At the firm level, Quiet Capital is more broadly diversified across AI, consumer, enterprise, fintech, healthcare, and deeptech ¹⁶.

Founder profile preferences: Humphrey’s emphasis on structured talent evaluation and reference-checking suggests a founder-assessment-driven approach rather than purely thesis-driven investing ¹. His own background as a technical founder (CS degree, 8 startups) likely inclines him toward technically credentialed founders.

Geographic focus: United States, specifically San Francisco Bay Area. Quiet Capital’s broader portfolio is 70% US-based ¹⁸.

Check size: $100K to $25M through Quiet Capital, with a personal sweet spot around $1M ¹²¹.

Co-investor patterns: Humphrey’s personal angel investments show co-investment with Reid Hoffman, Harvey Golub (former American Express CEO), Greylock Partners, SoftBank, and Lowercase Capital ¹⁷²⁰. At the firm level, Quiet Capital co-invests alongside a broad range of top-tier funds.

Notable pattern: Humphrey’s career arc — from serial founder to prolific angel to VC co-founder — gives him direct operational experience in fintech/real estate and e-commerce. His personal portfolio leans heavily toward fintech and financial infrastructure, while his firm role gives him broader sector exposure.

Note: Only 11 of Humphrey’s claimed 75+ personal angel investments could be independently verified through public sources ¹⁰¹⁷. The inferred thesis above should be understood as based on a small, potentially non-representative sample of his full investment activity.

Portfolio

The following table includes independently verified investments attributed personally to Matt Humphrey (not just Quiet Capital generally).

Note: This table represents approximately 12 of 75+ claimed personal angel investments. Many of Humphrey’s investments are not publicly attributed. As a co-founder and managing partner at Quiet Capital, he also co-leads the firm’s 262-company portfolio, but individual attribution for firm-level investments is not available ¹⁶¹⁸.

In Their Own Words

On entrepreneurship and embracing failure, from a Carnegie Mellon Project Olympus profile: “Step one: completely and utterly embrace failure.” ⁷

On learning by doing, from the same CMU profile: “Just getting in it and doing, you learn so much more perspective.” ⁷

On his philosophy of rapid iteration, from a Fintech Nexus podcast interview: “I took a philosophy of just start things, learn, rapid pace, rapid prototype, get products to market and if we’re going to succeed, great and if we’re going to fail, let’s fail fast, learn and iterate.” ⁵

On LendingHome’s founding insight, from the same podcast: “If this asset class of mortgage is so big and both the borrowers and investors have trouble accessing it in a simple, fast, reliable way, what if we did it better with tech?” ⁵

On LendingHome being his proudest achievement, from the same podcast: “I am more proud of what we’ve built here than probably all of the past 7+ combined.” ⁵

On customer-first approach at LendingHome, from the same podcast: “We win on service, we’re here to be a customer company that wins on service, enabled and growing through technology.” ⁵

On stepping down from LendingHome, from the Kiavi press release announcing his transition: “It has been a great honor to serve as the CEO of LendingHome since founding the company in 2013, and I am incredibly proud of everything our team has accomplished together in the last seven years.” ¹²

What Founders Say

Dedicated searches of Twitter/X, podcast transcripts, press coverage, and founder review platforms did not surface testimonials from portfolio founders about their experience with Humphrey as an investor.
