Magdalena Yesil

Background

Magdalena Yesil is a Turkish-American entrepreneur, venture capitalist, and angel investor who has been a pioneering figure in Silicon Valley since the early days of the commercial internet ¹². She holds a Bachelor of Science in Industrial Engineering, a Bachelor of Science in Management Science and Engineering, and a Master of Science in Electrical Engineering, all from Stanford University ¹.

Yesil began her career as a semiconductor design engineer at Advanced Micro Devices (AMD) ¹. She was an early advocate for commercializing the internet, and when her plan to purchase internet access providers from universities could not get venture capital backing, she joined UUNet, the first commercial internet access provider, which later went public ¹².

Yesil was a serial entrepreneur, founding two successful electronic commerce companies. CyberCash, a pioneer in secure electronic payment systems, debuted as a publicly traded company in 1996 ¹². She also founded MarketPay, an embedded payments software company described as the world’s leading compensation management and benchmarking software ¹.

She spent eight years as a general partner at US Venture Partners (USVP), making investments across a broad spectrum of technology startups ¹. She is perhaps best known as the founding board member and first investor of Salesforce, serving on its board from inception through post-IPO ¹³. When Marc Benioff struggled to raise money from Sand Hill Road venture capitalists for what would become Salesforce, Yesil was one of the early believers who provided angel funding alongside Larry Ellison and Halsey Minor ³.

In 2017, Yesil authored Power Up: How Smart Women Win in the New Economy, with a foreword by Marc Benioff ⁴. She was named Entrepreneur of the Year by Red Herring magazine ¹. She is also the co-founder and executive chair of Informed, an AI startup serving the financial services industry ⁵. She founded Broadway Angels, an angel investment group composed of women investors and business executives ¹.

She currently serves on the boards of Smartsheet (SMAR) ⁶, Zuora (ZUO) ⁷, and SoFi ⁸, and previously served on the board of PicsArt ⁹.

Stated Thesis

(Self-reported: These represent what Yesil says publicly about her investing approach. See Inferred Thesis for analysis of actual investment behavior.)

Yesil has described her investment evaluation as focusing on two primary factors:

• Team quality as the top criterion: When considering an investment, Yesil has stated that the most important factor is the team — the founders who are the custodians of invested money. She evaluates their ability to deal with difficulty, their staying power, and how scrappy they are, asking whether they are willing to do anything and everything to make the venture successful ¹⁰.

• Market size and timing: She also focuses on the market because, as she has stated, no matter how hard entrepreneurs work, if the market size is not large enough or is not ready for the product, the venture will most likely fail ¹⁰.

• Entering unconquered fields: Yesil has advocated becoming an expert in an emerging field, trend, or invention — for her, this was the internet — by entering an unconquered field to be a first mover and shape the future of that space ¹⁰.

• SaaS and subscription models: Her early investment in Salesforce and subsequent board seats at Zuora and Smartsheet indicate a publicly stated affinity for SaaS and subscription-economy businesses ⁷⁶.

Inferred Thesis

The analysis below is based on 16 verified investments and board positions that can be attributed to Yesil through her Broadway Angels bio, press releases, and public records. This represents a partial view of her investing activity across USVP and personal angel investments.

Sector distribution (16 verified investments): - SaaS / enterprise software: 5 of 16 (31%) — Salesforce, Zuora, Smartsheet, Socialcast, WebAction - Fintech / payments: 3 of 16 (19%) — CyberCash (founded), SoFi, iEscrow - Consumer internet / media: 3 of 16 (19%) — theRealReal, PicsArt, Dotomi - Security / infrastructure: 3 of 16 (19%) — Securify, Valicert, 3Ware - AI / data: 2 of 16 (13%) — Informed (co-founded), Freshplum

Key patterns:

• SaaS and cloud computing early adopter: Yesil’s most notable investment — being the first investor in Salesforce — exemplifies her pattern of recognizing transformative SaaS and cloud computing models before they become mainstream. Her subsequent board seats at Zuora and Smartsheet reinforce this pattern.

• Payments and financial infrastructure: From founding CyberCash (one of the first secure online payment companies) to investing in SoFi and iEscrow, Yesil has a recurring focus on financial technology and payment infrastructure.

• Successful exits through acquisition: A significant portion of her portfolio companies were acquired: Socialcast by VMware, Catch by Apple, Freshplum by TellApart/Twitter, Dotomi by ValueClick, 3Ware by AMCC, Securify by Kroll, iEscrow by eBay ¹. This pattern suggests a preference for companies building technology that becomes strategically valuable to larger acquirers.

• Active board participation: Unlike many angel investors, Yesil takes board seats and serves in active governance roles. Current and past board seats include Salesforce, Smartsheet, Zuora, SoFi, PicsArt, and Informed ¹⁶⁷⁸⁹.

• Women-led investing: Through Broadway Angels, Yesil has created a network of women investors, reflecting a commitment to diversifying the investor landscape ¹.

Notable gap: Despite her stated focus on market timing and first-mover advantage, several portfolio companies (theRealReal, PicsArt) are in consumer markets rather than the enterprise/infrastructure segments where her deepest expertise lies. This suggests opportunistic investing alongside thesis-driven plays.

Portfolio

In Their Own Words

On entrepreneurship and investing:

“Being an investor is an easy, lifestyle job… Being an entrepreneur is being the lowest in the power chain… But I am a curious person and want to see how far I can push new ideas, so I keep coming back to being an entrepreneur.” — Magdalena Yesil, FinTech Istanbul interview, 2017 ¹¹

On resilience:

“The biggest lesson I have to share is that it is always very very hard to start a company and win in the marketplace. You have to be ready to be told your idea is stupid and does not have a chance.” — Magdalena Yesil, FinTech Istanbul interview, 2017 ¹¹

“Being ready for a lot of rejection is good training.” — Magdalena Yesil, FinTech Istanbul interview, 2017 ¹¹

On choosing mentors:

“The most important factor in choosing your first job will be your boss. Having a boss who has the time and interest to teach you, to guide you and ultimately to sponsor you in the organization.” — Magdalena Yesil, FinTech Istanbul interview, 2017 ¹¹

On personal power:

“Within each of us lies 100 percent of the capability needed to overcome the obstacles to any goal we set for ourselves. You are much more powerful than you think.” — Magdalena Yesil, Power Up, 2017 ⁴

On leadership:

“Leadership sets the tone. And a leader who is willing to listen to people who speak their mind is usually a very powerful and very secure leader.” — Magdalena Yesil, SUCCESS magazine interview ¹⁰
