Amit Avner

Background

Amit Avner is a General Partner at Operator Partners, a self-funded venture firm he co-founded in 2020 with Nat Turner, Zach Weinberg, and Gil Shklarski ¹². Based in Tel Aviv, Avner is the only partner located outside New York ¹.

Avner began programming at age 10 and built one of the world’s first meta-search engines, WittySearch, at the age of 14 ²³⁴. He completed his computer science degree at The Open University of Israel while still attending high school ²³.

After high school, Avner served in an elite intelligence unit of the Israeli Defense Forces, where he researched and developed innovative technologies ²³.

In January 2009, Avner founded Taykey, an advertising technology company that helped advertisers deliver real-time, topical messaging by analyzing approximately 2 billion daily data points from social networks, blogs, and traditional sites ³⁴. Taykey raised $17 million in funding over five years and was backed by Sequoia, SoftBank, and Eric Schmidt’s Innovation Endeavors ¹³. Taykey was acquired by Innovid (NYSE: CTV) in 2017 ¹².

Avner is also the co-founder and chairman of Labrador Health, a saliva-based diabetes diagnostics startup he co-founded in 2021 with Yoav Kessler ⁵. Labrador Health was acquired by Healthy.io in 2025 ⁵.

As an angel investor, Avner was the first investor in Plaid, participating in its 2013 seed round led by Spark Capital ¹⁶. Plaid was later valued at $5.3 billion in Visa’s acquisition attempt ¹.

Stated Thesis

Operator Partners publicly describes its approach as “operators funding operators” ¹. Avner has stated that the fund’s investment “goes beyond money” because the partners bring their experience of building companies ¹.

The fund invests exclusively with the partners’ own capital, with no outside LPs ¹⁷. Avner has explained this structure by saying the fund does not lead rounds or take board seats, instead writing $250K-$1M checks alongside lead investors ¹⁷. If there is not already a lead, Operator Partners will help find one ⁷.

Avner has described the fund’s support model as on-demand rather than prescriptive, telling entrepreneurs after investing to reach out whenever they need help rather than chasing them for updates ¹.

Avner’s personal investment focus areas include AI, fintech, and health IT across pre-seed, seed, and Series A stages ⁸. His sector preferences include developer tools, enterprise software, cybersecurity, future of work, and health ⁹.

Inferred Thesis

Based on 18 verified investments in the portfolio table below, the following patterns emerge. Note: Operator Partners has invested in 144+ companies as of January 2026 ¹⁰, so these 18 represent approximately 12% of the total portfolio and percentages should be treated as directional only.

Sector breakdown (18 verified investments): - Fintech / Payments: 4 of 18 (22%) — Plaid, Unit, Ramp, Deel - Healthtech / Digital Health: 3 of 18 (17%) — Spring Health, Apella, Nourish - Cybersecurity / Security: 3 of 18 (17%) — Bridgecrew, Stytch, Material Security - Enterprise / Developer Tools: 3 of 18 (17%) — Prefect, QA Wolf, Serval - E-commerce / Marketplaces: 2 of 18 (11%) — Whatnot, Landis Technologies - Other (biotech, consumer): 3 of 18 (17%) — Benchling, Otterize, Prequel

Stage distribution (18 verified investments): - Seed: 10 of 18 (56%) — Plaid, Bridgecrew, Unit, Stytch, Material Security, Otterize, Prequel, and others - Series A: 6 of 18 (33%) — QA Wolf, Serval, and others - Series B: 2 of 18 (11%) — Landis Technologies, Apella

Geographic patterns: Portfolio skews heavily toward US-based companies, with some Israeli startups (Bridgecrew, Unit, Otterize) reflecting Avner’s Tel Aviv base ¹.

Co-investor patterns: Operator Partners frequently co-invests with Battery Ventures, Sequoia Capital, GV (Google Ventures), and NFX, consistent with the fund’s non-lead strategy of writing checks alongside established lead investors ⁷¹¹.

Notable pattern: The stated thesis emphasizes operator experience and founder support rather than specific sector focus. The actual portfolio confirms broad sector diversification with no single sector exceeding 22%, suggesting the fund is genuinely founder-driven rather than thesis-driven in sector selection.

In Their Own Words

“We are operators funding operators. Our investment goes beyond money, we also bring with us our experience of building companies.” — Amit Avner, CTech interview, November 2020 ¹

“We are essentially only risking our own money without any outside investors. We just collected money from the group and are investing it via the fund in projects that excite us. This creates a situation in which we completely trust each general partner to make the best decisions as quickly as possible with as little complications as possible. Instead of wasting our time on raising money, we get to invest it in what we really love and work with our entrepreneurs.” — Amit Avner, CTech interview, November 2020 ¹

“We are essentially coming to entrepreneurs after making an investment and tell them ‘this is our mail, our phone number and when you need something send us a message.’ We understand the strain entrepreneurs are under at every stage of the way, we were there. So we don’t chase our entrepreneurs looking for updates, but rather give them control and are there for them when they want to consult, onload, and talk.” — Amit Avner, CTech interview, November 2020 ¹

“A dirty little secret about startups is that from the outside, everything looks amazing…when you’re going inside, it’s a bunch of duct tape that’s holding everything together.” — Amit Avner, CTech interview with Michael Matias, 2021 ¹⁵

“For me, it’s all about the people. It’s about finding the people you want to work with and you want to be on a journey with.” — Amit Avner, CTech interview with Michael Matias, 2021 ¹⁵

“We simplified the process…we meet a company, and when we invest in you, we say, ‘Here’s our email, here’s our WhatsApp. If you need anything, just come to us and we’ll help.’” — Amit Avner, CTech interview with Michael Matias, 2021 ¹⁵

“Product is the key. You need to understand your market and what they want.” — Amit Avner, Under30CEO interview ³

“Do something you love. You’ll be awesome at it, it won’t feel like work, and everything else will solve itself.” — Amit Avner, Under30CEO interview ³
