Cecilia Ziniti and the Case for Leaving a Good Job

Cecilia Ziniti’s boss sent her a link to a legal AI meetup. It was a small gesture with a fairly large implication. She was general counsel at Replit, a company helping people build software, and she had become absorbed in what language models might do for lawyers. Amjad Masad, Replit’s CEO, had noticed. Was her head still in the job?

She has told the story with affection for Masad. The link helped make a possibility harder to ignore. She had wanted to start a company; her father was an entrepreneur. Now she was watching engineers use AI in their daily work and trying the technology on the documents that filled her own. A familiar profession was beginning to look different.

She arranged for a successor. Her last day at Replit was November 1, 2023. A week later, General Counsel AI, Inc. was incorporated. Her co-founder, Bardia Pourvakil, was an engineer she had worked with at Replit. The customer they intended to serve was someone Ziniti knew rather well: the lawyer inside a company, fielding questions from everyone else.

A blue light, and an unanswered question

Long before that departure, Ziniti had been drawn to places where technology created questions faster than anyone could settle them. As an undergraduate, she moderated an early online chat room. In 2002 she moved to Silicon Valley and joined Yahoo’s legal department as a paralegal. The internet was already a business. Its consequences were still being worked out.

Her education took her through Georgetown, the London School of Economics and Berkeley Law, where she earned her JD in 2009. At Morrison & Foerster, she worked on the smartphone litigation involving Apple. She liked the assignments that asked what a company should actually do. Litigation could examine a product after the argument had started. Product counseling offered a seat closer to the beginning.

In 2013 she joined the early Alexa team at Amazon. Voice technology brought a particularly tangible question: how would customers know that a device was streaming data to the cloud? Ziniti has described thinking through that problem, including the Echo’s blue light ring. A legal question had a visible expression on a household object. The answer had to make sense to the person using it.

That connection runs through her later work. New technology arrives with capabilities; people need a way to understand and use them. Her career moved through consumer robotics at Anki and autonomous vehicles at Cruise. By the time language models became part of her working day at Replit, she had spent years alongside products whose rules were still taking shape.

The customer already knew the problem

Her three general counsel roles were at Anki, BloomTech and Replit. Cruise was a different position, director and lead counsel. The distinction matters because the general counsel is responsible for a company’s legal function, with all the variety that modest phrase conceals. A request can arrive from sales, hiring, product or the board. Each comes with its own deadline and appetite for detail.

Ziniti’s route into BloomTech, then known as Lambda School, illustrates her willingness to approach a business before a job exists. She had followed CEO Austen Allred on Twitter and contacted him to suggest that, having raised money, he probably needed a general counsel. If she was not the person, she might know someone. When a role later opened, she pursued it and joined full-time in August 2019.

She was interested in the school’s effort to make a technology career accessible to more people. That attraction to what a product might enable also helps explain her response to language models. At Replit in early 2022, she tried them on contract drafting and review. Here was software reaching into the substance of her work, beyond organizing files or collecting signatures.

“I built for the job I had actually done.”

Cecilia Ziniti, on GC AI’s in-house focus

The difference is practical. A legal answer has to fit a company’s industry, jurisdictions and negotiating positions. An indemnity clause acceptable in one deal may be unacceptable in another. Ziniti identifies context as an especially difficult problem: it depends partly on the judgment of whoever asks the question. GC AI’s onboarding and playbooks aim to capture that company knowledge. The document is only part of the assignment.

The family business was teaching

Before the company’s funding announcements, there were lessons. Ziniti and Pourvakil began with a newsletter about AI and law, then taught lawyers how to prompt. The classes brought them into contact with early users and the particular ways those users needed help. Teaching gave a potential customer something to try. It also gave the founders questions worth answering.

Even the company’s name owes something to listening. Ziniti has said a How I Built This episode featuring the founder of Sun Bum helped inspire it. She liked the idea of telling people what a business does. General Counsel AI gives the prospective customer a useful clue before anyone opens the product.

For Ziniti, that work has a family history. She has described her mother, grandmother and great-grandmother as teachers. Her father, who built a manufacturing business, represented another possible path. Founding GC AI brought the two influences together. Explaining a tool, hearing where someone struggles and making it more useful can occupy the same afternoon.

The classes are practical. Lawyers work through tasks rather than merely hear that AI will change their profession. Her course listings include introductory prompting, advanced prompting and using AI in Microsoft Word. That progression acknowledges a mundane obstacle to adoption: a person can believe a technology matters and still have no idea what to do with it at nine o’clock on Monday.

Her ambitions extend to how legal teams learn to work. She uses the image of a trained runner receiving a bicycle: skill remains with the rider, while the tool changes the distance they can cover. It is an unusually unthreatening way to introduce a machine into a profession accustomed to checking every word. The lawyer still has to steer.

The comma meets the calendar

Ziniti enjoys language at a level of detail that will be familiar to anyone who has worked beside a meticulous editor. She notices the punctuation other people sail past. In discussing the move to CEO, she has named that precision as a habit that needs managing. Writing copy is enjoyable. A founder also has to make decisions quickly across an entire business.

Her general counsel experience gave her close contact with those decisions. Being CEO adds responsibility for their outcome. The scope expands from advising colleagues to owning the choices about people, product and money. She has spoken warmly about the role while acknowledging that the habits which helped her reach it need adjustment. The comma will always offer a small, solvable problem. The company offers considerably more.

She also takes communication beyond the sentence. Ziniti advocates emojis in internal legal advice because she wants the message to reach the people who must act on it. A correct answer sitting unread has limited value. The preference fits her view of in-house work as part of the business: the legal department has to communicate with colleagues who have other things on their minds.

For decisions of her own, she has offered a less technological tool: a little distance from Thursday. “Never make a decision on a Thursday,” she says, describing how the accumulated pressure of a week can alter perspective. Waiting until Monday can change how a problem looks. It is a memorable qualification to the usual startup enthusiasm for speed. Even a founder may occasionally consult the calendar.

A bigger company, the same old inbox

By November 2025, GC AI was reporting more than 1,000 customer companies. It announced a $60 million Series B led by Scale Venture Partners and Northzone, at a company valuation of $555 million. The announcement also reported annual recurring revenue rising from $1 million to more than $10 million in under a year. Those figures mark a period of growth; they do not make the everyday product decisions disappear.

Ziniti has said she would rather be recognized for building a good business than for fundraising. The distinction directs attention back to the people using it. In 2026 she appeared on Inc.’s Female Founders 500 list. At the GC AI Summit that year, her product demonstration addressed contracts in Word and legal questions arriving through Slack. The locations were familiar territory for her former self.

She introduced that session with a joke about being under NDA, then made clear that it was not. The demonstration included negotiation playbooks and redlines, along with a Slack scenario involving a business colleague who needed help while the lawyer was away. For a company selling AI, the situation was pleasingly ordinary. Somebody had a question. Somebody else was on vacation. Work continued.

Her longer view is of more legal work happening inside companies, with lawyers staying close to the business and using their judgment on harder calls. GC AI is her attempt to build toward that arrangement. The ambition follows the same curiosity that took her into a chat room, Yahoo’s legal department and the Alexa team: what will people need when a technology becomes part of their day? This time, she gets to decide what to build in response.
