How EvenUp, Supio and Eve Won Plaintiff Firms

About this episode

A good drafter with a complete file can turn out a solid personal injury demand in a day or two. The weeks go somewhere else: waiting for records, itemized bills and lien amounts. Three companies have turned the demand letter, and the case prep behind it, into a product anyway.

In Episode 3 of WhoBringsTheBusiness, Sagar Pratap Singh breaks down how EvenUp, Supio and Eve won plaintiff firms: EvenUp by selling a finished demand with human review, Supio by selling the organized case file, and Eve by selling firm owners on becoming AI-native. He then explains why the slowest part of a demand is rarely the writing, and gives three things a firm that still drafts by hand can change this week.

Key takeaways

• The demand isn’t late because of the writing. The delay sits in records, itemized bills and liens. Under the HIPAA Privacy Rule a provider has up to 30 days, plus one 30-day extension, to answer a patient’s own records request.
• Sell the outcome the buyer is missing. EvenUp sold a finished demand, reviewed by people, rather than software a firm had to learn.
• Own the facts underneath. Supio sold the organized case file first and added demands later, because a demand is only as strong as the facts behind it.
• Change only sticks when someone at the top owns it. Eve sold firm owners on a new way of running the firm, and the managing partner is usually the one quoted.
• Three things to borrow this week: a demand-readiness checklist used as a gate, a fixed one-page demand structure, and records requests sent the day treatment ends.

The last hospital bill

It is a Tuesday afternoon. The client finished treatment six weeks ago, the file is clean, and the demand is half written. It is not going anywhere, because one hospital still has not sent its itemized bill, and until it does, nobody can put a number on the page.

Welcome back

Welcome back. Last week we stood at the front door of the law firm, with Smith.ai on the phones, Lawmatics on lead follow-up, and Finch taking the chasing work off a paralegal’s plate.

Today is about the demand letter, and the case prep behind it. Three companies have turned that work into a product for plaintiff firms: EvenUp, Supio and Eve. Each won its buyers with a different move, and I want to look at all three. Then we will talk about what it means for a firm that still drafts its demands by hand.

A quick note before we start. Most of the numbers you will hear today are company announcements or press reports. I will tell you where each one comes from, and the full source list is in the show notes.

The problem: why demands sit

Let me start with the problem, because it is not the one people usually describe.

For more than 12 years I worked on the support side of US law firms: intake, medical summaries, demands, follow-ups. One thing I learned early is that drafting the demand is usually the quick part. A good drafter with a complete file can turn out a solid demand in a day or two. The weeks go somewhere else.

They go into waiting for records, for an itemized bill instead of a one-line balance, and for a lien amount from a health plan that has no reason to hurry. Then a provider sends the wrong date range and you ask again.

Some of that waiting is written into the rules. When a patient asks for their own records under the HIPAA Privacy Rule, the provider has up to 30 days to act, and it can take one more 30-day extension if it explains the delay in writing. That is the federal ceiling, in 45 CFR 164.524, and state rules and provider backlogs vary from there. So a firm can do everything right and still wait close to two months on one provider. Put six providers on a single car accident case and you can see why a demand sits.

So when you hear that AI writes a demand in minutes, it is true, and on its own it does not touch the slowest part of the job. All three companies we are about to look at have worked that out.

Playbook 1: EvenUp, sell the finished demand

EvenUp was founded in 2019 in San Francisco by Rami Karabibar, Raymond Mieszaniec and Saam Mashhad, a former litigation attorney. The origin is personal. Its investor Bessemer writes that a car accident left Raymond’s father permanently disabled, and the family settled for a fraction of what the claim was worth.

The money came quickly once the model worked. A Series D of 135 million dollars in October 2024 took the valuation past one billion. In October 2025 came a 150 million dollar Series E led by Bessemer, at a valuation above two billion, with 385 million raised in total, according to the company. EvenUp says more than 2,000 firms use it and that it handles over 10,000 cases a week.

It was not an easy sell. Karabibar told Fortune that early investors kept telling them, “Legal tech sucks, AI sucks, personal injury sucks.”

So what was the move? EvenUp did not lead with software that a firm had to learn. It sold a finished demand. The firm uploaded the raw file, meaning records, bills and the police report, and got back a demand package with a damages figure built in, drawing on a database of past verdicts and settlements. And there were people in the loop. EvenUp says more than 100 legal and medical professionals review and refine demands before they reach the attorney. One attorney said it plainly on EvenUp’s own blog: “I trust your AI because you internally review demands before they come to me.”

A PI attorney does not want another tool. They want the demand off their desk, done to a standard they trust, and EvenUp sold exactly that. Once it owned the demand, it widened into medical chronologies, analytics and what it calls a Claims Intelligence Platform. In May 2026 it launched Pre-Litigation as a Service, where EvenUp’s own US-based staff and its AI run records and bills retrieval, treatment tracking, demand preparation and even negotiation with carriers. The company says early testing brought in more than ten million dollars in subscriptions.

Now two fair pushbacks. In late 2024, Business Insider reported former employees saying humans did much more of the work than the AI story suggested. EvenUp’s answer was that it has always run a hybrid model. From where I sat, human review is not a scandal. It is what the firm is paying for. The real question is whether the firm knows who touched its file.

The second is the “US-based staff” line. I understand why it is there, but location is not quality. I have seen excellent demand work done offshore and weak work done onshore. What makes a demand reliable is a defined checklist, a second reviewer and clean source records, wherever the team sits.

For your firm: take your last ten demands and note two dates for each one, the day the last record or bill arrived and the day the demand went out. If the gap between those is small and the wait before it is long, a faster drafting tool will not fix your timeline. Your records process will.

Playbook 2: Supio, sell the organized case file

Supio comes from a different place. It was founded in 2021 in Seattle by Jerry Zhou and Kyle Lam, childhood friends who had worked together at Microsoft and at Avalara. TechCrunch reported that they chose personal injury and mass torts after meeting hundreds of lawyers at conferences.

Supio came out of stealth in August 2024 with a 25 million dollar Series A led by Sapphire Ventures, and around 30 firms, according to TechCrunch. In April 2025 it raised a 60 million dollar Series B, again led by Sapphire, with Mayfield and Thomson Reuters Ventures joining, for 91 million in total. In July 2026 the company said its customer base had more than doubled in the first half of the year, and that recurring revenue had grown seventeen times since it left stealth.

Supio’s move was close to the opposite of EvenUp’s. Where EvenUp sold the finished letter, Supio sold the organized case file. Its software takes in medical records, police reports, insurance claims and bills, classifies them, and lets the firm’s own people search the evidence, build chronologies and see the whole case in one place. Zhou told TechCrunch that the system runs “hundreds of models at a given time” to understand documents. It was sold as a subscription priced on case volume, and used by the firm’s own paralegals and attorneys.

Why did that win buyers? Because a demand is only as strong as the facts underneath it, and the same organized facts serve litigation and mass tort work across hundreds of files. Supio points to TorHoerman Law’s 495 million dollar verdict against Abbott Labs as a case where its platform was used. A verdict like that has many authors, but it tells you Supio was selling to firms that expect some cases to go the distance.

The demand letter came later, as a feature on top. Supio launched Instant Demands in August 2025, claiming 97 percent accuracy against manual review. Then it made a smart distribution choice. Rather than fight case management systems, it plugged into them, and into Westlaw through Thomson Reuters.

For your firm: pick one open case this week and build a proper chronology before anyone starts the demand. Every visit, provider, date, diagnosis and charge, each linked to its page in the records. If that takes your team more than a few hours, you have found where the time goes, and you have found what any tool you buy needs to solve first.

Playbook 3: Eve, sell a new way to run the firm

Eve was founded in 2020 by Jay Madheswaran, a former Facebook engineer, with David Zeng and Matt Noe. It launched publicly in October 2023 with 14 million dollars in seed funding, raised a 47 million dollar Series A led by Andreessen Horowitz in January 2025, then a 103 million dollar Series B led by Spark Capital that September, at a valuation above one billion. Fortune reported more than 100 customers at the Series A. By June 2026, the company said it supports more than 1,400 plaintiff firms.

What makes Eve different is that it was never only about personal injury. One of its best-known early partners was an employment firm. In June 2024, Barrett & Farahany, a labor and employment firm, announced it was working with Eve to become an AI-native law firm, and said discovery responses that used to take 10 to 20 hours now took 30 to 45 minutes. Today Eve lists employment, personal injury, workers’ compensation, Social Security disability and medical malpractice.

So Eve’s move was not a single product. It was an identity. Eve sold plaintiff firm owners on becoming a different kind of firm, and let flagship customers announce that change in public, under their own names. Frontier Law Center did the same in early 2024, and Mike Morse Law Firm in Michigan appears in Eve’s announcements again and again.

That works because of how plaintiff firms get paid. As Andreessen Horowitz pointed out when it invested, these firms earn on contingency, not on hours, so capacity is the business. Madheswaran said it directly in April 2026: “Plaintiff firms don’t hit a ceiling because they lack cases.” If you believe that, you do not buy a demand tool. You buy a new way of running the firm. That is where Eve has gone in 2026, with agents that work cases forward and an auditor that checks for missed deadlines and overlooked injuries, with attorneys approving the work.

One caution from me. AI-native reads well in a press release. Inside a firm, it means rewriting job descriptions, retraining case managers and a messy few months. Notice that in these stories the person quoted is usually the managing partner. The change only sticks when someone at the top owns it.

For your firm: decide who owns the demand process. One named person, not “the team.” Give them the authority to change templates, set the records checklist and choose tools. Without that, any platform you buy becomes one more login.

What all three have in common

Step back and look at the three together.

Each one started with a narrow, painful piece of plaintiff work and earned trust there before widening. EvenUp started with the finished demand. Supio started with the organized case file. Eve started with firm owners who wanted to rebuild how their firm ran.

Each is now heading to the same place, the whole case from intake to resolution. And each has worked out that the slow part of a demand is not the writing. EvenUp now retrieves records and bills itself, Supio partners for retrieval, and Eve has built agents for client and provider outreach.

All three also sell to the same buyer logic. A plaintiff firm does not care about software for its own sake. It cares about how many cases each person can carry, how fast they resolve, and what they settle for.

What your firm can borrow this week

So what can a firm that still drafts by hand borrow this week? Three things.

One. Build a demand-readiness checklist and use it as a gate. No file goes to the drafter until every provider’s records are in, every bill is itemized, and every lien amount is confirmed in writing. Drafting from a half-complete file is how you end up drafting twice.

Two. Fix your demand structure on one page. Liability, then injuries and treatment in date order, then specials with a total that ties back to the bills, then general damages, the policy limits position, and the ask. Once the structure is fixed, anyone on the team, or any tool, can fill it.

Three. Send your records and bills requests the day treatment ends, or earlier where you can, and track every provider against a due date. With a 30-day clock and a possible extension, a request sent late becomes a demand sent late.

The Transferable Bit

Now the transferable bit, for those of you outside law.

The lesson from these three is that the work your customer complains about is rarely where the real delay sits. PI firms said they needed faster demands. What they needed was the records and bills in hand. A clinic says it needs more patients, when the real leak is the follow-up after the first visit. A consultancy says it needs to write proposals faster, when the real delay is getting the client’s data in the door.

EvenUp won by delivering the finished outcome. Supio won by organizing the raw material. Eve won by helping owners rebuild how the business runs. Choose the approach that fits your buyer, but first find out where the waiting really happens.

Legal tech players in demands and chronologies

A few more names working on demands and case prep.

Filevine launched Demands AI inside its platform in 2023, with certified partners using AI to assemble the demand and the lawyer reviewing the final draft. More on Filevine next week.

Litify, the case management platform, launched its own Instant Demands in June 2026, with Supio doing the document analysis underneath.

YoCierge works on medical records retrieval, and has partnered with Supio to feed HIPAA-compliant records straight into case analysis.

And a reminder that this market moves fast. Precedent, whose Demand Composer was built for PI demand packages, is listed on LegalTechnologyHub as having ceased operations in April 2026. Before you commit, check that a vendor is likely to be around for the life of your cases.

Wrap-up

That is Episode 3. If you want the demand-readiness checklist I talked about, the records, bills and liens checklist plus a one-page demand structure, comment or reply with the word DEMAND and I will send it over.

Next Thursday, the 5th of November, we move from the demand to the system the whole firm runs on: How Filevine, MyCase and Smokeball Won the Small Firm.
