Manifest OS Closes $60M Series A at $750M Valuation — Largest Round in Legal-Tech History (April 28, 2026)

Manifest OS on April 28, 2026 announced a $60 million Series A at a $750 million post-money valuation, led by Menlo Ventures with participation from Kleiner Perkins, First Round Capital and Quiet Capital. The company is calling it the largest Series A in the history of legal technology, and the proceeds will fund a roll-out of AI-native, fixed-fee law firms operating under the Manifest Law brand.

What Happened

Founder and CEO Dan Mishin told Bloomberg Law the round closed earlier in April and was over-subscribed, with the lead Menlo cheque written by Matt Murphy. According to a BusinessWire press release issued the same morning, Manifest will use the capital to scale its proprietary AI software stack — covering client communications, legal research, document drafting, billing and reporting — and to add lawyers to the affiliated Manifest Law firms.

Unlike traditional legal-tech vendors that sell software to existing firms, Manifest OS is structured as a holding company that operates the firms it builds. Its first vertical is U.S. business immigration; reporting in Law.com describes a model in which Manifest's AI handles intake, document generation and case-management work that traditionally consumes paralegal and associate hours, while licensed attorneys keep client-facing and judgement-bound work. The firm advertises a 15 percent higher visa-approval rate than the U.S. national average and client response times that are roughly three times faster than incumbents.

Key Details

• Round size: $60 million Series A at a $750 million post-money valuation, led by Menlo Ventures with Kleiner Perkins, First Round Capital and Quiet Capital participating.
• Cumulative funding: Manifest OS has now raised more than $90 million across all rounds, according to Artificial Lawyer.
• Traction: Eighteen months in, Manifest says its platform has handled more than 3,000 client engagements and delivers a 15 percent higher U.S. business-visa approval rate than the national baseline.
• Access stat: Manifest cites that roughly 80 percent of American businesses and consumers cannot afford a lawyer when they need one, while average law-firm billing rates rose 7.4 percent in 2025 and top partners now charge up to $3,000 per hour.
• Founder: CEO Dan Mishin previously founded JuneShine and built Manifest after navigating his own U.S. immigration case — the consumer pain point that anchors the product roadmap.

What Developers and Users Are Saying

Reaction in the legal-tech community has been a mix of admiration and skepticism. Artificial Lawyer's Richard Tromans described the round as "a generational bet on alternative business structures" but noted that Manifest's holding-company model only works in jurisdictions that allow non-lawyer ownership — currently Arizona and Utah in the U.S., plus the U.K. ABS regime. On Hacker News, top comments focused on whether AI-generated immigration filings will hold up as USCIS adjudicators get better at spotting boilerplate; on r/Lawyertalk and r/LegalAdvice, practising immigration attorneys debated whether the 15 percent approval-rate uplift is causal or selection bias on easier cases.

Investors interviewed by PYMNTS were more straightforwardly bullish, framing Manifest as the first credible attempt to combine modern AI tooling with a fixed-fee law firm at scale — a thesis that Harvey and EvenUp validate from the software side but that no one else has tested with operating firms attached.

What This Means for Developers and Legal Buyers

For software vendors, the signal is that legal-AI capital is shifting downstream: from selling tools to law firms to becoming the law firm. Manifest joins NewLaw operators such as Atrium (now defunct) and Garfield Law in the U.K. as the most-funded experiment in alternative business structures yet. For corporate legal-ops buyers, the more concrete near-term implication is that fixed-fee immigration work backed by AI document generation is now plausibly priced — Manifest's published pricing for L-1 and O-1 work is roughly half of typical Big Law rates, and the round gives it the runway to keep undercutting incumbents while it iterates on its model.

What's Next

Mishin told Legal IT Insider that the next twelve months will focus on three things: launching Manifest Law in two additional U.S. practice areas beyond business immigration, expanding into Arizona's ABS regime to operate licensed firms there, and opening a U.K. office to take advantage of the SRA's longer-standing alternative-business-structure rules. The company has not committed to a public roadmap for its software stack but has said it will publish technical posts on its policy and retrieval pipelines later in 2026.
