vLex Innovator Q&A Series with Zach Posner of The LegalTech Fund
The LegalTech Fund's Zach Posner discusses the evolution of legal tech as an investment category, the transformative impact of generative AI, and why 2025 will see fundamental shifts in legal service monetization models.
The transformation of legaltech from a niche concern to a mainstream investment category didn't happen by accident. In today's rapidly evolving legal landscape, understanding how this ecosystem developed—and where it's heading—is crucial for legal professionals across all sectors. Our vLex Innovator Q&A Series continues with a conversation that gets to the heart of this transformation.
We're thrilled to share our latest interview with Zach Posner, co-founder and managing partner of The LegalTech Fund, the venture capital firm that has arguably done more than any other organization to establish legaltech as a legitimate and thriving investment category. In our conversation with vLex's Chief Strategy Officer, Ed Walters, Zach discusses his journey from edtech to legaltech, the community-building philosophy behind the legendary TLTF Summit, and his bold predictions for how AI will reshape legal service delivery and monetization.
Zach's 25-year journey in technology and venture capital uniquely positions him to analyze the forces reshaping the legal industry. From his early days at venture firms like Insight Partners to building and selling an education platform that served 12 million students globally, Zach brings a cross-industry perspective that has proven essential to understanding legaltech's potential. The LegalTech Fund has invested in more than 70 companies and helped build the connective tissue that makes the modern legaltech ecosystem possible.

From EdTech to LegalTech: An Accidental Discovery
Zach's entry into legaltech wasn't planned, it was discovered through necessity. After building an edtech platform that was acquired by McGraw-Hill, he and his team pivoted to helping organizations manage vendor relationships, initially targeting the education sector they knew well.
"So the next thing we did once the company was acquired is we helped a friend get started, and he started a vendor risk company, and the design was, let's go help schools manage their vendors," Zach explains. "And we went to our law firm, and the law firm on the first day said, forget about schools. We need this as a law firm. We're using more and more third-party applications. So from then, we spread to law firms. We pivoted on the day of incorporation to law firms."
This pivot revealed a startling gap in the market. "What we kept realizing was, and as we're talking to these entrepreneurs, there was no ecosystem available to them at all. There was no place to go for venture capital. There were no funds that could tell the difference between a firm that bills by the hour and a plaintiff firm."
Rather than seeing this as an obstacle, Zach recognized the opportunity. "But we kind of looked at it and said, well, this is kind of an amazing opportunity for all these companies. Ed, as you know as well as anybody, these are hard customers to get in with. But once you're in and they start using your product and liking your product, it's a hard customer to get out of. And that's kind of a beautiful profile."
This insight became the foundation for The LegalTech Fund's strategic approach. Instead of raising capital from traditional venture investors, Zach focused on bringing in strategics—law firms like McDermott Will & Emery and Orrick, and companies like DocuSign and Carta—who could help portfolio companies succeed through more than just capital.
Legal as the Universal Connector
One of Zach's most compelling insights is his vision of legal as the universal business function that touches everything. This perspective helped him understand why legaltech deserved to be its own category rather than a subset of other enterprise software markets.
"Part of the vision that we had is we think legal sits in the middle of everything and it intersects with everything that we do. I even like saying now from birth certificate to will, everything that we do in our life is governed by a legal doc," Zach reflects.
This universality creates interesting category definition challenges. "And the question is, ‘hey, do you view a CLM type of technology as legaltech or as sales enablement?’” As Zach notes, “the funny part is none of these companies in general would ever identify as legaltech if they had their way."
Despite these definitional challenges, Zach saw the power in bringing together a community that had never been connected before. "What we did is say, look, there's an active community of folks here that have never been brought together to interact with each other and everybody wants to help everybody. So if we start to push the construct of this category, we think good things will happen. And I think so far, it's working."
The ChatGPT Moment That Changed Everything
While Zach and his team built the foundation for legaltech as an investment category, he's quick to correct any suggestion that they made it "sexy." That credit, he argues, belongs entirely to GenAI.
"No, we didn't make it sexy. GenAI made it sexy. LLMs made it sexy. Because when we got into this, our thought process and where we're still happy playing all day long is basic, boring workflows," Zach emphasizes.
The transformation began with a specific moment that Zach considers historic. "So you'll go back to November 30th, 2022, right? And when ChatGPT really came out with their first demo. And I'm convinced it's the best tech demo that I've ever seen. I'll put it in my lifetime."
The scale of ChatGPT's adoption was unprecedented. "I think the stat is zero to 100 million users in 60 days. And to give you a sense of content, like now we can benchmark that against something like Facebook. It took Facebook five years to get there."
This demo created a cascade effect that transformed the entire investment landscape for legaltech. "And then as you recall that, that was followed up by Goldman Sachs coming out with a report that said 44% of all legal work is susceptible to AI. It's the number one vertical… the number one opportunity to kind of go after and create some big businesses."
The impact was immediate and dramatic. "And I think that starting four or five months later, every generalist fund in the world said they need a legal bet. And as I described to you from 2016 to 2020, no generalist fund wanted anything to do with legal. So that's what made it sexy."
Today, the transformation is complete. "And I feel like we've become the popular kid. I mean, we're getting, my guess is at least 10 to 15 inbounds from investors on a weekly basis at this stage."
The Cross-Industry Playbook
Central to Zach's investment philosophy is the belief that legal isn't fundamentally different from other industries, it's simply been slower to adopt proven solutions from elsewhere. This perspective drives The LegalTech Fund's approach to identifying opportunities.
"There's nothing in legal we haven't seen in other categories and it's really logical as to how you get from point A to point B. If you think about legal work, a lot of it is one foot ahead of the next. And a lot of this can be automated, tech enabled. And I think GenAI is just an accelerant for all of this."
This philosophy extends to financial services infrastructure. "At the end of the day, we think the entire fintech ecosystem needs to be reinvented for legal. Think about every case that's out there. That's an asset for somebody, a liability for somebody. And ignoring a relatively small litigation financing market, like why aren't there more products here to help folks?"
The approach consistently produces what Zach calls "aha moments." "Docket Alarm, like you guys aren't reinventing, you just created a user experience that is so good and so easy that how could you not use it? And I think we're still at that ‘duh’ moment."
Community Over Competition: The TLTF Summit Philosophy
Perhaps nowhere is Zach's community-building philosophy more evident than in the TLTF Summit, which has become one of the legal industry's most influential events. The summit's success stems from a fundamental insight about the fragmented nature of the legaltech ecosystem.
"We started an event a couple of years ago called the TLTF Summit. And I think the secret of the Summit is bringing these people together that have historically never been together."
The event deliberately breaks down traditional silos. "You know, if you think about all the shows that we've all gone to, you think about ILTACON that has the law firm leaders or Legalweek, or CLOC that thinks about the corporate folks. But you know… we're all working on the same types of problems."
This mantra extends to the event's famous networking advice. "And we encourage people, it is such a well curated group of folks that I say this in the beginning every year, like I say, skip a session, skip every session, you know, because it's just about the people that you meet in the coffee shop."
The underlying philosophy is community-driven rather than competitive. "We know that people can help each other. And if people help each other collectively, we'll all achieve our goals. Because as you said, like the rest of the world, they're out there to get us in different competitive ways. But if there's a legaltech community that emerges strong, everybody wins."
Law Firm 2.0: The Coming Unbundling
Looking toward the future, Zach envisions a fundamental transformation in how legal services are delivered and structured. His concept of "Law Firm 2.0" represents a shift away from the one-stop shop model that has dominated large firm strategy for decades.
"We think technology is going to enable the unbundling of a law firm," Zach explains. "In fact, the big ones that our minds always go to, they've spent the last 20 or 30 years doing M&A to effectively be a one-stop shop."
Zach illustrates this with specific examples. "So I was skiing over the winter and I saw an ad in Colorado and it said skilaw.com. And if you think about something like, I know there's a horselaw.com that my friend, a friend of ours has told stories about, or fishlaw.com. And there's only so many permutations as to what can happen and why you would need a lawyer in and around the horse."
The business model implications are significant. "So we look at things like that and say, could you put technology behind it? Could you train the technology to look for certain characteristics? And could you deliver a better, simpler user experience at a significantly lower price, but with actually a higher margin?"
Zach points to Carta as an early example of this model. "You know, I look at a company like Carta that is effectively managing companies' cap tables. Cap tables are something lawyers used to manage. Lawyers don't do that anymore. Carta does. In fact, lawyers recommend Carta."
The key insight is partnership rather than competition. "But you can think of Carta as an early version of Law Firm 2.0 of just saying, hey, all we're going to do is cap tables. And no, we're not going to do this and butt heads with the law firms. We're going to do this in partnership and in collaboration with them. And they're actually going to send us all their clients."
2025 Predictions: Three Market Shifts That Will Define Legaltech's Future
Zach's predictions for 2025 center on fundamental changes that reflect his deep understanding of both technological capabilities and market dynamics. His analysis reveals both opportunities and challenges as the legaltech ecosystem matures.
Prediction 1: The Monetization Revolution
The evolution of legaltech revenue models is approaching a critical transformation. Zach traces this progression from traditional SaaS pricing through transaction-based models to something entirely new.
"Part of Law Firm 2.0 is if you look at the evolution of legaltech and the monetization opportunities, let's say five, 10 years ago, we were thinking a lot about SaaS software, some sort of recurring revenue. Let's say that was $50,000 to $5,000 a month," Zach explains.
Transaction-based pricing improved returns significantly, but the next phase promises even greater impact. "And now like this law firm 2.0 construct is saying, hey, let us shrink the price of some of these legal services and kind of take it all. This is the big trend we think you're going to see coming in the next couple of years."
This creates what Zach considers a historic opportunity: "But what we think this is for entrepreneurs is almost a once-in-their-career TAM expansion opportunity... when you look at it and say, well, wait, legal services is a $2 trillion market."
Prediction 2: The Great Generalist Slowdown
Zach's boldest prediction involves a significant shift in investor behavior as generalist funds reassess their legaltech strategies.
"A bold one I have not said publicly is I think you're going to see some of the generalists slow down... I think you're seeing all these massive rounds because these generalists have said we need a legal bet. But I think a lot of them have a bet right now. And I don't think they need five bets."
He situated this within historical patterns: "I think we've seen these waves and I think that they're a couple year cycles. I think we're coming to the end. And I don't think that's a bad thing."
Prediction 3: Quality Over Quantity in Capital Allocation
Zach's final prediction distinguishes between continued availability of growth capital and a normalization in early-stage funding.
"I think you'll still see massive headline numbers because there's a lot of money upstream. And so I think that if you're doing well, there will be series B, series C, series D capital for you. I just don't know if you'll see as much as we've been seeing in the pre-seed, seed."
This shift would reward entrepreneurs who focus on building businesses that customers actually want, pointing to successful examples of those who "raised very little, almost bootstrapped the whole thing. But that forced you to build a business that your end customers cared about."
The underlying message: the market is maturing from hype-driven speculation toward fundamentals-based investment, benefiting both entrepreneurs and the legal professionals they serve.
