The Venture Math Behind $8B Valuations, and Why It Matters to Legal Software Buyers

Summary of an essay from Dorna Moini's Legal Tech Notes, published on Substack on February 10, 2026. Dorna Moini is the CEO and Founder of Gavel and a former litigator at Sidley Austin. This page gives the argument and the numbers; the full essay is on Substack.

In brief: When a legal team picks a software vendor, it inherits that vendor's incentives. A startup valued at 150 times its revenue needs an enormous exit to count as a success, so its founders pursue bigger markets, faster growth and riskier bets, and customers feel that as pivots, price changes, turnover and sometimes a shutdown. The essay explains the mechanics (preferred stock and liquidation preferences), walks through Atrium, LawGeex and Robin AI, and gives buyers one question to ask: what kind of outcome does this company need in order to succeed?

What is a liquidation preference, and why should a buyer care?

Venture investors buy preferred stock, which is paid out before the common stock held by founders and employees. A liquidation preference sets how much they get first. At the simplest, a 1x preference means investors who put in $50 million take the first $50 million of any sale. Preferences stack across rounds, multiples of 2x or 3x are common, and "participating" preferred takes its preference and then a share of the rest.

The examples: a company that raised $200 million and sells for $400 million pays investors $200 million first and splits the rest by ownership. With a 3x preference, up to $600 million goes to investors first, so a $600 million sale can leave founders and employees with nothing. WeWork is the public example, where the preference stack, including participating preferred for its largest investor, left common stock nearly worthless even after a bailout. A buyer should care because the preference stack decides what outcome the company's leaders are actually working toward.

How do huge valuations change what a vendor builds?

At 150 times revenue with no profit, a middle outcome is a failure for the founders, so they chase the biggest possible market. For legal software that shows up as expanding beyond legal, rebranding as "enterprise AI" or "professional services," and drifting away from the workflows lawyers bought the product for. Pricing changes that help clear the preference stack follow.

Employees feel it through stock options. Options are a large share of startup pay and only have value if growth is exceptional; when growth falters they go underwater and key engineers leave. Customers see reshuffled teams and lost institutional knowledge. A company spending far more than it earns is also on what the essay calls a refinancing treadmill, dependent on the next round to keep operating.

What happened at Atrium, LawGeex and Robin AI?

Atrium, founded by Justin Kan, raised $75 million to rebuild the law firm as a tech-enabled business, never matched revenue to the cost of its large team, pivoted and shut down, leaving customers scrambling. LawGeex raised about $50 million for AI contract review, published benchmarks showing 94% accuracy against lawyers' 85% on NDA issue spotting, then had to add human labor, cut staff, split the business and was absorbed by another legal tech company. Robin AI raised more than $70 million on AI-first contract intelligence, failed to close a planned $50 million round in late 2025, and went through layoffs, a fire sale and closure.

The essay also names the outside-legal cautionary tales: Theranos at a $9 billion valuation on promises, Quibi's $1.75 billion and six-month life, and Arrival's $13 billion SPAC listing with no revenue. Against those it sets Clio, whose valuation rests on dominant market share, recurring revenue and methodical expansion, as what an earned valuation looks like.

What should a buyer ask a legal tech vendor?

"What kind of outcome does this company need in order to succeed?" If the answer is an extraordinary event the company is nowhere near, the risk to you as a customer is higher. Steady revenue, real customers and a sustainable cost base are the safer signal. In demos, the essay suggests asking what problem the company is obsessed with and which problems it has said no to; focus is the best tell.

On Gavel itself, the essay discloses that the company raised about $10 million at a valuation anchored to revenue, which lets it price rationally, invest in accuracy and decline markets that do not serve legal teams. In June 2026 Gavel was acquired by Relativity.

Key numbers and sources from the essay

• 1x liquidation preference on $200 million raised: investors take the first $200 million of a $400 million sale.
• 3x preference on the same raise: up to $600 million to investors before common stock sees anything.
• Atrium: $75 million raised, shut down after a pivot. LawGeex: about $50 million raised, 94% vs 85% NDA benchmark, later absorbed. Robin AI: more than $70 million raised, failed $50 million round in late 2025, closed.
• Theranos: $9 billion valuation. Quibi: $1.75 billion raised, about six months of operation. Arrival: $13 billion SPAC valuation with no revenue.
• Gavel: about $10 million raised at a revenue-anchored valuation; acquired by Relativity in June 2026.

What this means for a law firm or legal team

1. Add one question to every vendor evaluation: what outcome does this company need to succeed, and how close is it?
2. Check whether the vendor's roadmap is moving toward your workflows or away from them toward "enterprise" or "professional services."
3. Weight retention and real revenue over funding announcements. A $60 million round is a cost the vendor must recover from customers like you.
4. Use the contract review tool comparison and the document automation buyer's guide on gavel.io, which list each vendor's ownership and pricing where public.

Frequently asked questions

What is a liquidation preference?

The right of preferred-stock investors to be paid first when a company is sold. A 1x preference returns their investment before common shareholders get anything; 2x or 3x preferences and "participating" terms can consume most or all of a mid-sized exit.

Why does a vendor's valuation matter to a legal team buying software?

Because a company valued far above its revenue must chase an extraordinary exit to succeed, which shows up for customers as pivots away from legal, price changes, staff turnover and in some cases shutdown, as at Atrium, LawGeex and Robin AI.

What question should buyers ask legal tech vendors?

What kind of outcome does this company need in order to succeed? Companies with steady revenue, real customers and a sustainable cost base are safer long-term partners than those that need a once-in-a-decade exit.
