In a conversation with Arthur Rothrock on The Litigator's Path, Horst walks through the financial realities choking California's legal cannabis market, how he built and diversified a small firm around a niche that contracted beneath him, why he believes AI-driven efficiency gains will force litigators to rethink hourly billing, and what his one-on-one networking approach looks like in practice. The through line: a generalist litigator who bet early on a volatile industry, adapted when the economics shifted, and now sees AI adoption as both the biggest opportunity and the thorniest billing problem facing solo and small-firm attorneys.
Why California Cannabis Clients Can't Afford Litigation – and What That Means for Niche Practice Building
Horst entered cannabis law in 2016, drawn in after conducting a deep-dive analysis of insurance policies held by cannabis clients at Wendell Rosen and concluding that most policies failed to cover any meaningful operational risk. That niche insight – policyholder-side insurance coverage for an industry where almost no one understood the policies – made him one of roughly three insurance coverage attorneys serving the cannabis industry nationwide at the time.
The enthusiasm was real. Horst recalls attending the first Cannabis Law Institute hosted by what was then the National Cannabis Bar Association in Denver in 2017 and calling his wife to say he hadn't been this excited about law since law school. But the economics that made the green rush feel limitless have since collapsed, particularly in California.
The core problem is structural. Cannabis businesses face an effective tax rate Horst estimates at around 70%, driven by a 15% state excise tax (with an automatic 25% increase currently being fought in the legislature), local taxes, and a federal IRS provision – Section 280E – that bars companies trafficking in a controlled substance from taking ordinary business deductions. These businesses are "essentially taxed on revenue" rather than profit, Horst explains. Meanwhile, more than half of California's localities have opted out of legal cannabis sales entirely, leaving the illicit market as the only option in those areas and giving licensed operators a competitor with zero regulatory overhead.
The result for a litigator: clients who cannot afford professional legal services at market rates. Horst says he knows "very few California-based cannabis attorneys" who have not mentioned some form of pivot or diversification in the past two to three years. His own cannabis work has shrunk from a significant portion of his practice to a small fraction, and his marketing focus has shifted accordingly – toward local small and mid-sized business clients who can sustain a litigation relationship.
The lesson for attorneys eyeing a niche practice is blunt. Horst built real expertise and institutional credibility in cannabis law, but an industry's inability to pay for legal services overrides every other advantage. He hasn't abandoned the space – he remains active in INCBA and sees potential in expert witness work given his depth of knowledge – but he treats the niche now as one piece of a deliberately generalist firm rather than its centerpiece.
How Horst Thinks About AI Efficiency, Hourly Billing, and Alternative Fee Structures
Horst describes himself as a heavy early adopter of AI tools and believes their use will become standard of care for litigators – primarily because of the efficiency gains clients will demand. He references a colleague's experience with Legion, where eight pages of case material produced a fileable summary judgment motion for a few hundred dollars, and estimates that current AI tools can cut 50% or more of the attorney hours historically required for comparable work.
But he is candid about the billing math. For firms that charge by the hour, adopting AI tools creates a squeeze from both directions: the tech stack gets more expensive while billable hours drop. "You sort of get hit on both ends," Horst says. His response is to explore alternative fee structures – flat fees, value-based pricing – where the firm can capture some of the efficiency gain rather than passing all of it through as reduced hours billed. The logic is straightforward: if the work product is equal or better and the client pays less than they would have at a firm still billing six hours of associate time for a research memo, both sides benefit.
Horst compares AI output to first- or second-year associate work product, which "you should be vetting anyway." He tested Westlaw's Co-Counsel (formerly CaseTex) on a cannabis constitutional law question he knew well – whether the dormant commerce clause applies to the cannabis industry – and the tool pulled the correct cases but got one holding 180 degrees wrong on a circuitous decision. A first-year associate, he concedes, might have made the same mistake. The point is not that the tools are flawless; it is that a senior attorney can now ask a natural language legal question, receive a memo in three minutes, spot the errors immediately, and follow up with a second question without waiting a week for another research cycle.
He is also watching deposition tools closely, including real-time deposition analysis products that function as a digital second chair – flagging inconsistencies between testimony and documents during the deposition itself. For solo and small-firm litigators who cannot afford to bring an associate to every deposition, that capability changes what is possible.
Jason Horst's One-on-One Networking Strategy for Business Development
Horst is direct about where he fits in the business development spectrum. He draws a contrast with attorneys who generate clients from stage presence alone, noting that his strength is one-on-one conversation – "being able to engage back and forth" and letting people understand who they are dealing with at a deeper level. His marketing strategy, from the start, has been built around showing up: attending conferences, joining organizations, and building referral relationships with non-litigating attorneys who need someone they trust for litigation matters.
That approach worked exceptionally well in cannabis, where the industry's early conferences put him in rooms with potential clients and referral sources who valued personal connection over firm pedigree. INCBA became a major source of referrals. As the cannabis market contracted, Horst applied the same method to different rooms – local chambers of commerce, bar associations, and mixed-professional networking groups in the East Bay.
He also participates in a listserv of local small and solo firm attorneys that serves as a real-time resource for everything from expert witness recommendations to practice questions. That network has generated referrals directly: a transactional real estate attorney he met through the group has sent him multiple local real estate litigation matters.
For his growing mediation practice, the strategy is the same but with a specific goal: getting his name into enough databases and enough conversations that when litigators send out the standard "do you know anything about this mediator?" inquiry, someone in their network can vouch for him. The approach depends entirely on volume of genuine relationships, not advertising spend.
Scaling a Four-Attorney Firm With Gig Economy Talent
Horst started the firm alone, working from a home office with no outside capital. His first website was a Wix build he produced himself over three days – functional enough that someone who received his card would find a credible online presence, even if it performed poorly for SEO.
Growth came through the legal gig economy. Rather than hiring full-time associates from the start, Horst brought on contract attorneys case by case, building relationships over time with experienced practitioners who had left BigLaw but still wanted substantive work without the grind of full-time document review. This let him scale up during busy stretches and scale down during slow ones – critical for a solo-originated firm where revenue ebbs and flows are more dramatic than at a larger shop.
The downside is retention. When work slows, good contract attorneys find other engagements and may not be available when demand picks back up. Horst has lost people that way. But the model allowed him to grow to four attorneys without taking on debt or making premature full-time commitments. He eventually added a corporate and securities attorney – not work he could do himself, but work his existing litigation clients needed. His reasoning: smaller business clients benefit from a single firm that holds institutional knowledge of their business, priorities, and values, rather than re-educating a new attorney every time a matter falls outside the litigation lane.
He runs the firm's operations primarily through Clio, which he adopted on day one for intake, billing, and timekeeping. He is currently testing whether Microsoft's 365 ecosystem – SharePoint, OneDrive, and Copilot – can replace his previous document management setup, drawn by the improvements in real-time collaborative editing.
Why Horst Believes AI Will Push More Disputes Into Arbitration and Mediation
Horst sees a timing problem on the horizon. If AI tools allow attorneys to produce discovery requests in minutes rather than hours and draft motions at a fraction of the historical cost, the pace of litigation accelerates – but courts have no corresponding mechanism to speed up. Judges already dislike the volume of discovery motions on their dockets; Horst expects that volume to increase as the barrier to filing drops.
His prediction: more disputes will move to private arbitration and mediation, not necessarily because those processes are cheaper in absolute terms, but because the courts will become the bottleneck. "Structurally, the courts are not well situated to ramp up their operations in ways that can keep up with the efficiencies created," Horst says. He also raises an underappreciated concern – that attorneys using AI to draft discovery responses without careful oversight will produce answers that are "useless," generating avoidable disputes that further clog the system.
In his own mediation practice, Horst already uses AI to vet parties' legal arguments and briefs before sessions, making him a more prepared and persuasive presence in the room. He sees a future where parties can put a dispute in front of a mediator and receive an evaluative process much earlier in the lifecycle of a case, provided appropriate ethical disclosures and waivers are in place. For litigators who default to expensive saber-rattling before engaging in meaningful settlement talks, that shift could be significant.
What Litigators Can Take Away
-
Horst explores alternative fee structures – flat fees and value-based pricing – specifically because AI tools cut billable hours while increasing tech costs, and firms that stick to pure hourly billing will absorb the loss on both ends.
-
When evaluating AI-generated legal research, Horst treats the output as first-year associate work product: useful as a starting framework, but every cited case and holding gets independent verification before anything goes to a client or a court.
-
Horst built his entire book of business through one-on-one networking rather than stage appearances or advertising, focusing on attorney referral relationships – particularly with non-litigators who need a trusted litigation referral – and estimates that showing up consistently in professional groups generates more business than any single marketing channel.
-
By hiring contract attorneys case-by-case through the legal gig economy rather than committing to full-time associates, Horst scaled from a solo practice to a four-attorney firm without outside capital, accepting the trade-off that he occasionally loses good people during slow periods.
-
Horst advises litigators to initiate settlement conversations at the outset of a case rather than after tens of thousands of dollars in discovery spending, noting that AI tools may paradoxically make it easier to conduct targeted early discovery that strengthens settlement positioning without a full litigation buildout.
