Michael Eisenberg

Background

Michael Eisenberg (born May 18, 1971) is an American-born Israeli venture capitalist, author, and co-founder of Aleph, one of Israel’s leading early-stage venture capital firms ¹. Born in Manhattan, New York, Eisenberg is the eldest of seven children; his father was a lawyer and his mother ran various home businesses ¹. He was raised in an observant Jewish home, attended Orthodox Jewish schools, and graduated from Yeshiva University High School for Boys before completing a B.A. in political science and philosophy at Yeshiva University in 1993 ¹².

In 1993, Eisenberg and his wife Yaffa immigrated to Israel ¹. He founded a startup merchant bank in 1995 focused on technology consulting ³. Between 1997 and 2005, he was a partner at Israel Seed Partners, where his investments included Shopping.com (acquired by eBay), Finjan Holdings, GuruNet, and Answers.com ¹³.

In 2005, Eisenberg joined Benchmark Capital as General Partner and was appointed the firm’s representative in Israel ¹⁴. At Benchmark, he led investments in Wix.com, Gigya (acquired by SAP in 2017), and WeWork, and invested in Conduit and Seeking Alpha ¹⁵. He served on Wix’s board as Independent Director from 2010 to 2015 and on WeWork’s board from 2012 to 2020 ⁶.

In 2013, Eisenberg co-founded Aleph with Eden Shochat ¹⁷. Aleph has raised four funds: Fund I ($150M, 2013), Fund II ($180M, 2016), Fund III ($200M, 2019), and Fund IV ($300M, 2021), totaling approximately $830M under management ⁸⁹¹⁰. The firm has invested in over 50 companies ⁷.

Eisenberg is the author of The Tree of Life and Prosperity: 21st Century Business Principles from the Book of Genesis and maintains the blog “Six Kids and a Full Time Job” (since 2006) ¹¹³. He was ranked #8 on the Forbes Midas List Europe in 2021 ¹. He established the Nevo Network in 2020, a fellowship program supporting immigrants working in Israeli high-tech ¹¹. He resides in Jerusalem with his wife and eight children ¹¹¹.

Stated Thesis

Eisenberg publicly describes his core investment thesis as “investing in humanity” ¹². He has stated that social media has peaked and “the next technological revolution and investment trend is humanity,” arguing that technology should enhance rather than encase human experience ¹².

Through Aleph, Eisenberg says the firm focuses on “partnering with great Israeli entrepreneurs to build large, meaningful companies and impactful global brands” ⁷. He has emphasized the importance of investing in companies that address fundamental human needs, stating: “Human beings actually crave true community, communities of help and success, not online tribes of diatribe” ¹².

Eisenberg has described himself as a generalist investor, stating: “I’m a generalist mostly because I don’t know much about anything” ¹³. He favors boutique, smaller firms over multi-stage firms, believing that “time is more precious than money” and that staying small allows dedicated time to support entrepreneurs ¹³¹⁴.

On portfolio construction, Eisenberg has stated: “A portfolio should have somewhere between 15 and 25. Call it shots on goal” ¹³. He has also expressed a preference for relationship-driven investing over transactional approaches, advising founders to evaluate whether investors can “significantly expand their network, accelerate their learning” and provide “a high signal-to-noise ratio in feedback and questions” ¹⁴.

Inferred Thesis

Based on 62 verified portfolio companies listed on Aleph’s website ¹⁵, combined with Eisenberg’s pre-Aleph investments at Benchmark and Israel Seed Partners:

Sector breakdown (based on 62 Aleph portfolio companies): - Financial services/fintech: 16 of 62 (26%) — Lemonade, Melio, HoneyBook, Unit, Finaloop, Floodlight, RiseUp, Grain, Sequence, Colu, Fullpath, Travelier, Trullion, Uniper, Approve, Centrical - Logistics/supply chain/operations: 12 of 62 (19%) — Bringg, Freightos, Fabric, Windward, Brew, Embed, OneStep, Thriver, Workiz, Healthy.io, Reeco, Jiga - Data infrastructure/enterprise: 10 of 62 (16%) — Coralogix, Anecdotes, SparkBeyond, Panorays, Umbrella, TheGist, Ply, Finaloop, Geoquant, NextSilicon - Deep tech/hardware: 6 of 62 (10%) — Nexar, NextSilicon, Q (acquired by Apple), Sightful, Dream, SparkBeyond - Consumer internet/education: 8 of 62 (13%) — Simply (JoyTunes), Frank, TinyTap, Spines, Daily.dev, Houseparty, Embed, Svix - Cybersecurity: 3 of 62 (5%) — Dream, SecuriThings, SphereX - Real estate: 4 of 62 (6%) — Agora, Daisy, Placer.ai, Waltz - HR/workforce: 3 of 62 (5%) — Centrical, Compete, MyInterview

Stage focus: Primarily early stage (seed and Series A). Aleph’s website lists companies with founding dates ranging from 2013 to 2024, with investments typically made at or near founding ¹⁵. Signal by NFX reports Eisenberg’s typical check size as $1M-$5M with a sweet spot of $2.5M ¹⁶.

Geographic concentration: Exclusively Israel-focused. Aleph explicitly partners with “Israeli entrepreneurs” ⁷, though portfolio companies frequently have US headquarters or operations.

Notable patterns: - Strong emphasis on companies addressing real-world operational challenges (logistics, payments, insurance, healthcare) rather than pure software plays - Multiple exits via acquisition: Shopping.com (eBay), Gigya (SAP), Frank (JPMorgan), Houseparty (Epic Games), Q (Apple), Luminate (Symantec), Approve (Tipalti), Colu (HBSS Connect), Raftt (Wiz) ¹⁵ - Three IPOs: Wix (NASDAQ: WIX, 2013), Lemonade (NYSE: LMND, 2020), Freightos (NASDAQ: CRGO, 2022) ¹¹⁵ - Melio was acquired by Xero ¹⁵ - Co-investor patterns: Innovation Endeavors, Sequoia Capital, Bessemer Venture Partners, General Catalyst, Coatue Management appear across multiple Aleph portfolio companies

Gaps between stated and inferred thesis: Eisenberg’s “long humanity” thesis is broad, but portfolio data shows a disproportionate concentration in financial services/fintech (26%) and logistics/operations (19%), suggesting a more specific interest in companies that digitize legacy industries with complex operational workflows.

In Their Own Words

“My core venture capital investment thesis for the next decade is to invest in humanity.” — Michael Eisenberg, CTech, 2018 ¹²

“Social media has peaked, the next technological revolution and investment trend is humanity.” — Michael Eisenberg, CTech, 2018 ¹²

“The worst investing decisions I’ve made are the ones where I did too much due diligence and talked myself out of a good deal.” — Michael Eisenberg, Jewish Insider, October 2019 ²⁴

“I’m a generalist mostly because I don’t know much about anything.” — Michael Eisenberg, 20VC podcast, December 2025 ¹³

“Being as dumb as I am and looking at this and knowing nothing about insurance turned out to be a hell of an advantage.” — Michael Eisenberg, 20VC podcast, December 2025 ¹³

“So on a personal level, I want to be a company builder alongside the entrepreneur and not an investor.” — Michael Eisenberg, 20VC podcast, December 2025 ¹³

“We are deep believers in the small fund theory.” — Michael Eisenberg, 20VC podcast, December 2025 ¹³

“If the founder wants my money based on Price, I’m not doing the deal.” — Michael Eisenberg, 20VC podcast, December 2025 ¹³

“Venture capitalists deal with uncertainty. You actually don’t mind the catastrophic outcomes. You could lose all your money. What you’re looking for is asymmetrical upside.” — Michael Eisenberg, 20VC podcast, December 2025 ¹³

“Innovation is constant. So I knew a lot of people in 2000, 2001 who took their foot off the gas from an investment perspective, and they let the psychology of the Nasdaq impact the psychology of early stage investing.” — Michael Eisenberg, 20VC podcast, December 2025 ¹³

“You will know you are doing real venture capital when you aren’t competing with other investors to finance a deal but are instead offering to invest in people, industries and ideas that don’t yet have access to capital. That is where money can be most useful, and also where returns can be the highest.” — Michael Eisenberg, Medium blog ¹⁴

“With the mindset of founders, our focus is devoted to accelerating startups to scaleups, and leveraging our relationships with customers, follow-on funders and talent, as well as Aleph’s proprietary technology tools and data, to better service entrepreneurs.” — Michael Eisenberg, NoCamels, December 2019 ⁸

What Founders Say

Daniel Schreiber, co-founder and CEO of Lemonade, discussed his experience with Eisenberg and Aleph on the Invested by Aleph podcast. Schreiber stated that he came into Lemonade believing “investors tend to do more harm than good” and that “there are investors who truly add value, and they are a small minority.” He initially planned to seek “dumb money” but acknowledged “I was wrong,” suggesting that his experience with Aleph as an investor changed his perspective on investor value-add ²⁵²⁶.

Eisenberg has noted that Freightos founder Zvi Schreiber engaged with Aleph from the earliest stage, with Eisenberg joining the board in August 2013 ⁶¹⁷. Eisenberg commented on the Freightos investment: “Networked software and big data are going to transform many industries in need of radical evolutions to service 21st century customers” ¹⁷.

No additional independently sourced founder testimonials found beyond the Lemonade podcast episode. The “Invested by Aleph” podcast features conversations with portfolio founders but is produced by Aleph and should be considered in that context.
