A word that holds the whole argument

Priori is named after the Latin a priori. The point of the name is the point of the company: hire a lawyer before you desperately need one, and you save time and money. It is a thesis compressed into seven letters, and Basha Rubin has spent more than a decade proving it out on the largest stage legal services offers.

Today she runs a marketplace that lets in-house teams find and hire outside counsel using data rather than firm letterhead. A general counsel posts a project. Priori returns a vetted, matched lawyer - often within a single business day - chosen on the deal types they have negotiated, the parties they have faced, the judges they have stood in front of, and how their matters actually turned out. The pitch is almost rude in its simplicity: stop hiring lawyers because someone you trust once mentioned a name.

The vetting is where the bite is. Roughly nine of every ten attorneys who apply to the network do not make it in. And generalists get a particularly cold reception. "We don't work with attorneys who say they are generalists," Rubin has said, "because we found that our clients are less satisfied with those people." Depth over breadth, evidence over reputation - the whole operation runs on that preference.

"Priori comes from the Latin phrase a priori - if you hire an attorney proactively rather than reactively, you'll ultimately save time and money."

Rewind to where the conviction came from. Rubin went through Yale Law School during the Great Recession, watching the firm business model strain in real time, and arrived at an unfashionable conclusion for a top-of-class graduate: the most interesting thing about law was not practicing it. "I had realized at the end of law school that what I was most excited about was the business of law," she has said. So in 2013, fresh out of Yale at 25, with no business background and no technology background, she co-founded Priori with her classmate Mirra Levitt.

It helps to know the family she comes from. Her father founded MultiPlan; her grandfather was a union organizer. Two generations of people who looked at an existing system and decided it could be rebuilt. Rubin took the family habit and pointed it at a market worth roughly $800 billion, where the default way of choosing a lawyer had barely changed in a century: ask around, hope for the best, get the bill later.

No experience, on purpose

Starting a venture-backed technology company with neither an MBA nor an engineering degree is the kind of thing that reads as reckless until it works. Rubin's answer was to treat ignorance as a method. She asks, by her own account, a relentless number of questions to understand how a system actually works before deciding it is broken. Ideas get pressure-tested with colleagues - subjected to intensive scrutiny - before anyone bets on them. The startup life, with its refusal to stay predictable, suited her.

The team grew past 50 employees and the funding climbed past $20 million, including a $6.3 million Series A in 2021. The pandemic, brutal for so much of the legal world, turned into an accelerant for Priori: legal departments suddenly needed flexible, remote, data-backed ways to staff work, which is more or less the company's reason to exist. Around the same time Priori shipped Scout, a product that hands in-house teams structured intelligence on outside counsel so the hiring decision stops being a guess.

"We don't work with attorneys who say they are generalists - we found that our clients are less satisfied with those people."

For the recognition-counters: Rubin has been named an ABA Journal Legal Rebel, a Financial Times Top 10 Legal Business Technologist, an LTRC Woman of LegalTech, and a Fastcase 50 winner. Priori has carried a Chambers Tier 1 ranking among global LawTech companies, and Rubin has a seat in Baylor Law School's "The Braintrust." The awards are nice. The interesting part is that an industry built on tradition keeps handing its rebel prizes to the person trying to rewire it.

The product line tells you how the thesis matured. Priori runs as a two-sided system: a global marketplace that connects in-house legal teams with vetted talent, and Scout, which feeds those teams structured intelligence about outside counsel before they ever pick up the phone. One half finds the lawyer; the other half makes the case for why that lawyer, with receipts. Over time Priori widened the door beyond general counsel to the legal-operations professionals who increasingly run the buying - the people whose entire job is squeezing waste and opacity out of legal spend. That audience did not really exist when Rubin started. The fact that it does now, and that it gravitates to a data-first marketplace, is its own quiet vindication.

Rubin has also done the unglamorous work of explaining the shift in public. Her bylines have run in Forbes, TechCrunch, Entrepreneur, and Inc., and she speaks regularly about how technology is changing - and will keep changing - the market for legal services. The argument she keeps making is not that lawyers are obsolete. It is that the way clients find lawyers is stuck in an analog era, and that transparency, accountability, and data can give clients many of the benefits of a big firm far more nimbly and far more cheaply.

Hire early, manage with empathy

Rubin's single most-quoted management rule is a counter to how most companies actually behave: "Hire good people when you find them, not when you desperately need them." It is the a priori thesis again, turned inward - act before the crisis, not during it.

Her sense of management traces back to an unlikely two days in 2004 spent registering voters, which taught her that different people carry genuinely different skills, and that the manager's job is matching the person to the work that fits. She lists empathy, perseverance, honesty, and humility as the competencies she cares about, and runs a "no job too small" shop. To her younger self she offers the advice she clearly took herself: stop chasing prestige, start chasing impact.

She met both her co-founder Mirra Levitt and her life partner, Scott Grinsell, at Yale Law - the same building that produced the idea now reshaping how companies buy legal help. The partnership with Levitt is worth dwelling on: a classmate who became a close friend and then a co-founder, splitting the company so that Rubin runs as CEO while Levitt leads product. Founder breakups are the most common way startups die quietly; theirs has held for over a decade, through fundraising rounds, a pandemic, and the slow grind of selling change to one of the most change-averse industries on earth.

Beyond Priori she sits on the boards of A Blade of Grass and the Rubin Museum of Art, and is a World Economic Forum Global Shaper - the institution's network of younger leaders working on civic problems. The throughline from a grandfather organizing unions to a granddaughter on civic boards is not subtle: this is a family that treats institutions as things you are supposed to improve, not just inhabit. And yes, she half-jokes that the real productivity secret is triple lattes.

She is candid, too, about what it took to raise money as a woman building in a category investors did not yet understand. On the record she has walked through the specific, often loaded questions female founders field in pitch meetings and how she learned to answer them - a small public service for the founders coming up behind her, and an extension of the "pay it forward" ethic she credits for her own start. Help people when you can, she figures, because someone helped you.

What ties it together is a refusal to accept that "how it has always been done" is the same as "how it should be done." Referrals, firm prestige, billing in the dark - Rubin treats each as a bug, not a feature. Whether or not the whole legal-services market reorganizes around data in her lifetime, she has already moved the argument from the fringe to the boardroom. That is the strange specific worth remembering: a 25-year-old with no business experience looked at an $800 billion industry and decided the problem was that nobody had the right information at the right time. Then she went and built the information.

In Her Words

The lines she keeps coming back to

I had realized at the end of law school that what I was most excited about was the business of law.

Hire good people when you find them, not when you desperately need them.

Priori comes from a priori - hire an attorney proactively rather than reactively, and you'll save time and money.

We care about the depth of their expertise. We don't work with attorneys who say they are generalists.
