The Lawyer Who Learned the System From the Inside
Diana Frappier came out of UC Hastings in 1996 with a J.D. and a B.A. in Social Welfare from UC Berkeley - and went straight into criminal defense. San Francisco's courts in the late 1990s were the same as they are everywhere: a place where the people with the fewest resources got the worst outcomes. She saw clients lose jobs, lose housing, lose custody - not because of what they did, but because they couldn't make bail while waiting for a trial that often resulted in no conviction.
That same year, she co-founded the Ella Baker Center for Human Rights with Van Jones - the activist and future CNN commentator and White House advisor who was then a young Oakland lawyer himself. The Ella Baker Center became one of the most influential criminal justice reform nonprofits in the country, spending decades on campaigns around juvenile justice, police brutality, civic engagement, and violence prevention in Oakland.
We deliberately select business partners aligned with social impact - treasurers who want money, or mayors who want their cities to perform better, instead of people who are inclined to incarcerate people.
- Diana Frappier, Co-Founder, PromiseGreen Jobs, Van Jones, and Seven Years at the Intersection of Policy and Operations
In 2005, Frappier and Van Jones launched the Ella Baker Center's Green-Collar Jobs Campaign. Within two years, Oakland had the first Green Jobs Corps in the United States - a direct pipeline from community to the clean energy workforce. It became a national model, directly influencing federal legislation.
When Green For All launched nationally in 2007 to take the green jobs movement to scale, Frappier served on its founding board. By 2008 she had moved into the Director of Finance and Administration role, eventually becoming COO. Seven years of running operations for a national advocacy organization teaches things a courtroom doesn't: budget cycles, government contracts, coalition building, the gap between what policy promises and what execution delivers.
In 2005, Frappier co-launched the first Green Jobs Corps in the United States from Oakland. A decade later, she was co-founding a startup in the same city to fix a different broken system.
Meeting Phaedra, and the Origin of Promise
Diana Frappier and Phaedra Ellis-Lamkins met through Van Jones. They worked together at both Green For All and later at Honor, the home health care startup. When Ellis-Lamkins got a call from a friend about bounty hunters at the door - a loved one had missed a court date and couldn't afford bail or a lawyer - the idea for Promise crystallized. Frappier joined as co-founder.
The original pitch was bail reform: a smartphone app that would help nonviolent pretrial detainees keep track of court dates, hearings, and paperwork, replacing incarceration with a community supervision model. Silicon Valley investors thought the idea was insane. Government work? Criminal justice? Frappier and Ellis-Lamkins walked into Y Combinator instead.
Y Combinator, Jay-Z, and $3.9 Million to Start
Promise joined Y Combinator's Winter 2018 batch and publicly debuted at Demo Day on March 20, 2018. The seed round included First Round Capital, Y Combinator, Kapor Capital, 8VC, Adelfos - and Jay-Z's Roc Nation, which put in $3 million at a time when the company was still finding its footing on the product pivot.
By 2021, Promise had closed a $20 million Series A led by Kapor Capital and XYZ Venture Capital - one of the largest rounds for a Black, women-led startup that year. In February 2022, The General Partnership led a $25 million Series B, with most of the original investors returning. Total funding crossed $48 million.
What Promise Actually Does Now
Promise is an AI-powered platform built for government agencies and utilities. It has four core products: PromiseBenefits (AI-automated relief distribution), PromiseAudit (real-time fraud detection), PromiseVerified (automated income verification), and PromisePay (flexible installment payment plans).
The numbers behind these products are not typical for government technology. WSSC Water enrolled 40,000+ customers and recovered $28 million using Promise's payment plans. The City of Richmond reduced outstanding government debt by $20 million with a 93% compliance rate. Louisville Water saw 15x more relief distribution in the first week than manual methods had achieved. Washington State used Promise to distribute $150 million to 690,000 households.
The standard implementation timeline is eight weeks. Self-service portal adoption rates run at 90%+. These are not the numbers of a government technology pilot program. They are production metrics from a platform that works.
Thirty Years of the Same Work, Different Tools
The through-line in Diana Frappier's career is not hard to find. From the Ella Baker Center to Green For All to Promise, every organization she has helped build is trying to close the gap between what government promises and what people actually receive. The tools changed - from courtrooms to nonprofit campaigns to Y Combinator-backed software - but the problem stayed constant.
At Promise, she serves as Chief Legal Officer alongside Ellis-Lamkins as CEO. In the company's narrative, Frappier is often described the way she was at the Ella Baker Center: the behind-the-scenes support that makes the public-facing work possible. Building operating systems is unglamorous work. So is running operations for a national nonprofit for seven years, or practicing criminal defense, or co-founding an organization that outlasts you by decades. Frappier has done all of it.
The company she helped build now operates in some of the most complex corners of American government. Utilities, child support, parking fines, emergency relief programs, income verification - these are not exciting categories for a startup pitch. They are, however, the places where people lose their water service or their housing or their ability to drive to work. Promise has built payment infrastructure in those places. The goal, as Frappier has put it, is to make it as easy to keep your water on as it is to buy something online.
