- โ Weinberg began his company with minimal industry connections, having practiced law for only eight months, and relied on cold-messaging thousands of lawyers on LinkedIn to secure initial calls.
- โ The global legal market is valued at approximately $1 trillion, but only about $30 billion is currently spent on technology, indicating a massive growth opportunity for AI startups.
- โ Legal-tech startups collectively raised $3.2 billion last year, and a majority of the top 10 largest US law firms by revenue are already using AI for workflows like document review and compliance checks.
A Bold Opening Move
In the high-stakes world of legal technology, first impressions are everything. For Winston Weinberg, co-founder and CEO of the AI startup Harvey, securing those initial meetings required a strategy that was as unconventional as it was risky.
Instead of walking potential clients through a standard feature list, Weinberg went straight for the jugular: he used Harvey to critique the lawyers' own arguments. This direct, confrontational approach proved to be the key to capturing attention in a crowded market.
The Critique Strategy
Weinberg detailed his early tactic during an episode of the Sequoia Capital podcast. Once he secured a call with a lawyer, he knew he had only seconds to make an impact. Rather than demonstrating generic capabilities, he pulled up publicly available court filings that the lawyers themselves had written.
He then prompted Harvey to analyze and critique the documents. "I would try to come up with prompts that were like, 'This is bad,'" Weinberg explained. This approach was designed to be provocative, turning a standard demo into a direct engagement with the lawyer's own work.
"Because they're a litigator and I'm basically attacking something that they just wrote, they would instantly read the screen."
This method forced immediate engagement. Lawyers, by nature, are critical thinkers. Having their own work analyzed in real-time by an AI tool created a compelling and unavoidable reason to pay attention.

High Risk, High Reward
The strategy was not without significant peril. Weinberg acknowledged that early versions of Harvey were prone to hallucinationsโgenerating incorrect or nonsensical information. A single bad output during a demo could have instantly destroyed credibility and ended the conversation before it truly began.
However, when the tool performed correctly, the results were transformative. Weinberg noted that on the occasions Harvey's analysis landed perfectly, it was a decisive victory. "But the times that they got it right, it was over," he said, indicating that a successful critique immediately won the lawyer's attention and interest.
This high-wire act required a deep understanding of both the technology's potential and its limitations. The payoff was a powerful demonstration of value that a simple feature walkthrough could never achieve.
Starting from Zero
Weinberg's unconventional demo strategy was born from a lack of traditional industry connections. When he started Harvey, he had been practicing law for only about eight months. "I didn't have any connections," he admitted.
With no warm introductions available, he turned to cold outreach on a massive scale. He messaged thousands of lawyers on LinkedIn to secure the early calls that were crucial for his startup's survival. This relentless effort laid the groundwork for Harvey's initial traction.
The company's progress has been rapid. Following a funding round in December led by A16z, Harvey reached a valuation of $8 billion. It has become one of the most closely watched startups in the legal AI sector, aiming to fundamentally transform how major law firms operate.
A Sector in Expansion
Harvey's rise mirrors the explosive growth of the legal AI sector itself. Weinberg stated that the scale of the opportunity is forcing constant evolution within his company, pushing him to "reinvent" himself as a founder every few months to keep pace with demand.
Despite Harvey's impressive valuation, Weinberg is skeptical of the idea of a single dominant winner in legal tech. He believes the market is far too large for one player to capture all the value. "There are around 10 million global legal professionals, and Harvey serves just single-digit percentage points of them," he said.
Investor confidence reflects this optimism. The global legal market is valued at roughly $1 trillion, yet only about $30 billion is currently spent on technology, leaving immense room for growth. Last year alone, legal-tech startups raised $3.2 billion.
Adoption is accelerating within firms. A majority of the top 10 largest US law firms by revenue have confirmed they are using AI for tasks like document review and compliance risk spotting.
Key Takeaways
Winston Weinberg's early strategy highlights a critical lesson in tech adoption: demonstrating immediate, tangible value is paramount. By directly engaging lawyers with critiques of their own work, Harvey cut through the noise and proved its utility in a way that resonated deeply with its target audience.
The legal AI landscape is set for continued expansion, driven by significant venture capital investment and growing adoption among established firms. As the sector matures, the focus will remain on tools that can deliver precise, reliable, and impactful insights.
