Seed Alchemy • Ten Unicorns • Zero Apologies
The woman who joined Google as its second attorney, helped it go from $85M to $10B in revenue, walked away from the General Counsel title, and then built one of the most data-driven VC firms in Silicon Valley - backing Palantir, SoFi, and Guild Education before anyone else was paying attention.
The list of people who have worked alongside Larry Page and Sergey Brin in Google's earliest days, then walked away from the General Counsel role, then co-founded a seed-stage VC firm that backed Palantir before most people could spell it - that list has exactly one name on it.
Miriam Rivera grew up speaking Spanish first, picking crops in upstate New York with parents who had migrated from Puerto Rico. Her family eventually settled in Chicago's inner city so she and her sister could attend school consistently. Sesame Street taught her English. She was identified as gifted in middle school, shipped off to Phillips Exeter Academy on scholarship, earned an AB in Sociology at Stanford, then came back for a master's in Spanish and Caribbean literature because she was going to be a professor.
Then she changed her mind. Again. Then again.
"People who hunger to be successful for more than just themselves are almost always in a better spot than somebody who is just thinking of Number One."- Miriam Rivera
The detour through Accenture, then a JD/MBA at Stanford Law and Business simultaneously, then Brobeck Phleger as an associate, then co-founding a startup with the man who would become her husband - Clint Korver - then Ariba, and finally a cold call into Google as its second attorney ever hired. The year was 2001. Google had about $85 million in revenue. Rivera left in 2006 when the number was $10 billion.
Inside Google, Rivera ran an unconventional legal operation. She eventually built a team of roughly 150 people - 50% of them women, a ratio that felt almost radical in the Valley at the time. She designed what she called "revenue velocity" - a systematic approach to contracts that helped scale Google's self-service advertising and syndication engines. The number she was responsible for: $14 billion in revenue.
There is a policy at Google today around extended maternity leave. It did not start as company policy. It started when Rivera quietly offered up to six months' leave to new mothers on her own legal team - twice the standard three months the company offered. She tracked the retention data. She brought it upstairs. Google formalized the policy company-wide. The detail that lingers: she was not asked to do this. She just did it and proved the math.
In 2006 she was offered the Google General Counsel role. She turned it down. Most people do not turn down the Google General Counsel role. She took personal time instead, and then asked herself what she actually wanted to build.
"My career advanced most quickly after I became a mother."- Miriam Rivera
In 2008, Rivera and Korver co-founded Ulu Ventures in Palo Alto. The name is Hawaiian for breadfruit - it also carries the meaning "to grow, to inspire, to be possessed as if by a spirit or god." The couple had fond memories of Hawaii. The name stuck.
The thesis was simple, if not easy to execute: most VC decisions are soaked in cognitive bias. Ulu would build a data-driven, rules-based investment model to reduce that bias systematically. Not as charity, not as diversity theater, but as competitive advantage. If you remove the filters that eliminate great founders before anyone meets them, you see more of the market than your competitors.
The early days were not smooth. When Rivera was raising capital for Fund I, a seasoned VC told her that venture capital was "a young man's game" when she asked for a limited partner referral. She has spoken publicly about that moment - not bitterly, but as evidence of precisely the bias she was setting out to defeat with math.
Ulu Ventures Fund I returned 5x to its investors. That number is not a coincidence. The portfolio includes ten companies that reached unicorn status: Palantir (now in the S&P 500), Guild Education, SoFi, BetterUp, Figure, Provenance, ZUM, HomeLight, Everlaw, and Krux - acquired by Salesforce for $700 million. Blue River Technology, acquired by John Deere for more than $300 million, adds to the exit column.
These were seed-stage bets. Not late-stage, not series B where the pattern is already obvious. Rivera was in the room before the narrative crystallized.
"We're not sacrificing anything by investing in women and minorities. Our ability to look at startups objectively and pick the ones with great potential makes us a top-performing fund."- Miriam Rivera
About 80% of Ulu's portfolio companies have a founder who is an immigrant, a woman, or from a minority group. This is not a marketing statistic. It is the direct output of a process designed to evaluate founders without the filters that traditionally narrow who Silicon Valley is willing to back. Thirty-eight percent women CEOs. Twenty-nine percent minority CEOs. Nineteen percent immigrant CEOs. The performance data is the argument.
In February 2025, Ulu Ventures announced Fund IV at $208 million, doubling total AUM to roughly $400 million. The firm is no longer proving a thesis. It is running a playbook that works.
A Puerto Rican girl in Chicago learned to speak English by watching Sesame Street. In 2022, Miriam Rivera joined the Sesame Workshop board of directors and took the chair of its HR and Compensation Committee. There is no cleaner narrative arc in Silicon Valley, and Rivera does not over-explain it.
She is also a Stanford University Trustee, holds the Stanford Medal (awarded to fewer than 1% of alumni), co-founded Stanford Angels and Entrepreneurs, and sits on the Kauffman Foundation board. She has four Stanford degrees across several decades, including a simultaneous JD/MBA - a detail that reads less as achievement-stacking and more as the logical result of someone who kept changing her mind about what to do next.
She and Korver also designed Ulu's rules-based investment process partly to prevent disagreements from spilling into their marriage. The fund is, among other things, a functional prenuptial agreement for founders.
"When you see those opportunities, jump on for the ride, get involved."- Miriam Rivera

"The first few years after I graduated, I kind of considered myself to be in a bit of indentured servitude until I paid down my student debt - and then could really pursue what I wanted to do, which was go into entrepreneurship and tech."
Sesame Street taught her English. She now chairs the HR & Compensation Committee at Sesame Workshop's board of directors.
"Ulu" is Hawaiian for breadfruit. It also means "to grow, to inspire, to be possessed as if by a spirit or god." Rivera and Korver chose it from fond memories of Hawaii.
She and husband Clint Korver designed Ulu's rules-based investment process partly to prevent fund disagreements from straining their marriage. The data methodology is also a relationship tool.
She turned down the Google General Counsel role in 2006. Most people do not turn down the Google General Counsel role.
Spanish was her first language. She took computer science courses in high school and participated in a Chicago city-sponsored computer program as a college sophomore - a decision that defined her entire career trajectory.
She and Korver co-founded Outcome Software together before either joined large companies. They have been building things together for over two decades.
