Manifest OS

Powering the next generation of AI-native law firms.

A client opens a laptop in a co-working space in Brooklyn, types one question about an O-1 visa, and gets a flat-fee quote before lunch. No retainer. No clock running in the background. No partner billing six minutes to read the email. This is the small, almost boring moment Manifest OS was built to create - and the legal industry spent a century making sure it couldn't happen.

Manifest OS is a New York company that calls itself an operating system, which is a generous word for what is really a quiet act of rebellion. It builds the software, the brand, and the back office that let a new kind of law firm exist - one where the price is fixed, the status is visible, and the lawyer is paid for the outcome rather than the hour. The firm it powers is called Manifest Law. The thing it is trying to retire is the billable hour.

"Most legal AI companies are selling shovels; Manifest OS is mining."

- Dan Mishin, Founder & CEO
01 - The problem they saw

A clock that nobody could read

The billable hour is the rare invention that manages to annoy everyone it touches. Clients hate it because they cannot predict it. Lawyers, privately, are not thrilled either - the model rewards time spent, not problems solved, which is a strange way to run a profession that sells judgment. Manifest points to a number that should embarrass the whole field: roughly 80% of American businesses and consumers cannot afford legal help when they actually need it. Rates, naturally, keep climbing - up an average of 7.4% in 2025.

The conventional fix has been to throw software at it. Mishin is unimpressed. "Selling AI to law firms can't fix the problem," he has said. "$6B went into legal tech last year, most of it toward tools that make the existing law firm model more profitable without changing whose interests it serves." It is a polite way of saying the industry bought faster horses.

"$6B went into legal tech last year - most of it toward tools that make the existing model more profitable without changing whose interests it serves."

02 - The founder's bet

The non-lawyer who read the fine print

Dan Mishin is not a lawyer, which turns out to be the point. He is an immigrant who spent tens of thousands of dollars - and a great deal of patience - going from an O-1 visa to US citizenship. Along the way he met the usual hospitality of the system: opaque timelines, vanishing communication, avoidable errors, premium invoices. Most people file that experience under "the cost of doing business." Mishin filed it under "business model in need of demolition."

His bet was that you cannot improve the law firm by adding features to it. You have to rebuild it. So Manifest split the atom in two: Manifest OS, the technology and operations company, and Manifest Law, a licensed firm. That separation is normally illegal in the United States, where non-lawyers cannot own law firms. Manifest got around the wall by walking through one of the few doors that exists - Arizona's Alternative Business Structure program, which permits exactly this arrangement. A regulatory footnote became a company's foundation.

"The way legal services are delivered today is not serving anyone well enough. When you redesign the system with AI at its core, you eliminate manual busy work and enable lawyers to focus on what matters."

- Dan Mishin

The short, suspiciously fast history

// roughly 28 months from idea to the largest Series A in legal tech
2024
Manifest OS is founded in New York. The plan: an operating system for law firms, not another tool for them.
~2024 (18 months before the raise)
Manifest Legal Services launches under Arizona's ABS program, starting in business immigration - and stays mostly in stealth.
2025
Traction quietly compounds: thousands of client engagements, 150+ corporate immigration programs including Whop and Orchard Robotics.
April 2026
$60M Series A at a $750M valuation, led by Menlo Ventures with Kleiner Perkins, First Round Capital, and Quiet Capital. Reported as the category's largest.
Next
Tax law named as the next practice area, with a stated ambition to power hundreds of firms across every major field.
03 - The product

Three parts, one promise

Manifest OS runs on three pieces that are easy to describe and hard to copy. There is the brand - every affiliated firm operates as Manifest Law, to a single standard of transparent pricing and service. There is the software - an AI-native platform that handles client communication, collaboration, legal research, document drafting, billing, and reporting, with human-supervised AI agents doing the busywork. And there is the back office - centralized intake, paralegal recruitment, quality assurance, and collections, so attorneys spend their day on cases instead of administration.

AI Drafter

Drafts immigration documents in a fraction of the time, with a lawyer reviewing the output rather than typing it.

AI Case Evaluation

Assesses case strength and likely outcome up front, so a flat fee can actually be quoted with a straight face.

Client Portal

One dashboard showing status and next steps. The radical feature here is simply knowing where your case stands.

Immigration Manager Portal

Lets companies run entire visa programs for their teams - 150+ of them already do.

The pricing model is the part that makes traditional firms wince: flat quotes based on outcomes, and a partial or full refund if a case is denied. A law firm offering money back is roughly as common as a casino doing it. That is precisely why it gets attention.

"The real opportunity in legal is not giving lawyers one more tool, but using AI to provide and power better legal services directly."

- Michael Bloch, Partner, Quiet Capital
04 - The proof

Numbers that did the talking

Stealth is a confident posture only if the metrics agree. By the time Manifest stepped into daylight in April 2026, it had built a record that made the round look less like a bet and more like a catch-up. Within roughly 28 months it had served thousands of clients - from solo startup founders to some of the largest technology companies on earth - and assembled a bench of attorneys with serious experience.

$60M, in context

// Manifest OS Series A vs. typical legal-tech Series A rounds (illustrative, USD millions)
Manifest OS
$60M
Large peer
~$25M
Typical round
~$12M
Peer figures are rough industry-typical ranges shown for scale, not exact comparables. Manifest's $60M was widely reported as the largest Series A in legal tech.

There is a quieter proof point that lawyers care about more than valuations: outcomes. Manifest reports that its approval rates on O-1 and EB-1 cases run above the USCIS national average. For a flat-fee firm that refunds losses, beating the average is not a marketing line - it is the business model staying solvent.

05 - The mission

Access, not just automation

It would be easy to file Manifest under "AI eats another industry." That misreads it. The company likes to point out that 55% of unicorn startups are founded by immigrants and 80% have immigrants in key roles - the exact people its first product serves. The mission is less about replacing lawyers and more about reaching the 80% of people who currently get priced out of the room. Automation is the method. Access is the point.

Five things that make Manifest odd (in a good way)

  • The founder is not a lawyer - he is a former visa applicant who got tired of the invoices.
  • The whole structure is legal thanks to an Arizona regulatory program most people have never heard of.
  • The attorney acceptance rate is reportedly under 1% - harder to join than most law schools.
  • It gives refunds on denied cases, which is nearly unheard of in legal services.
  • Its $60M Series A was reported as the largest in legal-tech history - while the company was still in stealth.
06 - Why it matters tomorrow

Immigration first, everything next

Immigration was the wedge, not the destination. Tax law is named as the next practice area, and the stated vision is a platform powering hundreds of AI-native firms across every major field. If that sounds grand, remember the model is portable in a way a single firm never is: the software, the brand, and the back office can be pointed at any practice where clients want a price and a deadline they can actually trust. Which is to say, all of them.

Back to that laptop in Brooklyn. The founder filed for an O-1 visa once and paid for the privilege of not knowing what was happening. Now someone like him can ask a question, see a fixed price, watch the case move on a dashboard, and get money back if it fails. The clock that nobody could read has been replaced by a number anyone can. That is a smaller revolution than "AI changes law forever," and a more honest one. Manifest OS did not make the law disappear. It just made the bill make sense.
