What happens if regulatory barriers to autonomous clinical AI fall faster than expected?
Clinical AI has the FDA to contend with – but recent signals (a new CDRH framework for assessing AI “competency,” ARPA-H’s new ADVOCATE program funding cardiovascular AI) suggest the path might be shorter than expected.
In his latest blog post, Venture Partner Duncan Greenberg explores that question and breaks down nine emerging categories of startups already building for that future.

Following @HalluminateAI's $30M Series A, CEO @Jerr_Wu joined @tbpn to discuss how the company is building training environments to help frontier AI labs improve their models.
The conversation covers what these environments look like, how performance is evaluated and scored, and what the next five years could hold for the space.

We're proud to announce that Oak HC/FT led Vitalize's $31M Series A.
Clinical staffing is one of the largest line items on every health system's P&L – and it still runs on spreadsheets, group texts, and heroics. Premium labor alone costs U.S. health systems an estimated $50B a year, much of it because the process for deploying staff hasn't kept pace with how fast demand actually changes.
Vitalize has built the air traffic control layer for healthcare's workforce – unifying staffing, scheduling, and capacity into a single platform that doesn't just recommend a fix, it executes one. Customers are seeing 10-20% reductions in premium labor spend, with go-lives now measured in weeks.
We back founders with earned insight into the problems they're solving, and Veeraj Shah and Sanketh Andhavarapu have exactly that. Proud to partner with them and the entire Vitalize team.

.@annielamont recently joined @MollySOShea on Sourcery to explore how AI is reshaping the line between healthcare and fintech, why AI in biotech is taking off, and how the AI shift is changing the way Oak evaluates companies.
In this clip, Annie discusses how Oak portfolio company @DevotedHealth is leveraging AI to build a business that could become “almost impossible to compete against in the future.”
Watch the full episode: youtube.com/watch?v=sjd_G6-k…
Annie Lamont says Devoted Health is one of “the best examples of AI applied to healthcare in the world right now.”
“Over the last year, they've tripled the size of their company. They halved the amount of their operating ratio. They dramatically increased their EBITDA.”
“You have a company that is almost impossible to compete against in the future.”

Today, we're proud to announce that Oak HC/FT led a $35 million Series A in Latitude, the global payments infrastructure company connecting stablecoin settlement to local payment rails worldwide.
Stablecoins have solved the middle of cross-border payments. The last mile – turning that settlement into money someone can actually spend – is still slow, expensive, or missing in most of the world. Latitude built that last mile: a single API that moves money into any market and lands it in local currency, in seconds, at transparent rates.
Before building go-to-market, the team spent its first year securing its own money transmitter licenses, reaching licensed or approved status across 45 U.S. markets in about eight months. That's the harder path – and the one that compounds.
We've tracked founders @cyril_mathew, Brian Wrightson, and Vivek Morzaria since before Latitude existed, and now we're proud to back them as they build.

.@RilletHQ just announced a $100M Series C at a $1B valuation, marking a major milestone in the company’s growth and its vision for an AI-native ERP.
We caught up with Co-Founder & CEO @nicckopp to talk about what’s driving that growth and where Rillet is headed next. The company is betting that AI can do more than augment decades-old accounting software – it can fundamentally rebuild how finance gets done. Nic discusses Rillet’s push upmarket and what the ERP of the future might look like.

Thrilled to keep backing @nicckopp and the entire @RilletHQ team. This marks Oak HC/FT’s third consecutive round with Rillet, as the company closes a $100M Series C at a $1B valuation.
Since first backing Rillet at the Series A, we’ve watched the team execute at a pace that’s rare even by startup standards. The numbers behind this round are a testament to the team’s momentum: Rillet has raised three rounds in the last year, bringing total funding to more than $200M. The company has doubled new ARR in just three months and now serves 600+ customers.
Congratulations to Rillet on this incredible milestone. We couldn’t be more excited to continue building alongside you.
Today we're announcing our $100M Series C at a $1B valuation, led by @ICONIQCapital. It's our third round in 14 months and brings our total funding to over $200m
The round came together in less than 48 hours.
We weren't planning to raise. Then new ARR doubled last quarter and we crossed 600+ customers including public companies and enterprises with $2B in revenue. Rillet AI agent usage is growing 70% each month and CFOs are replacing Oracle Fusion, SAP and Workday to run their companies on Rillet.
We also announced our alliance with EY and officially partnered with more than half of the top 20 CPA firms.
@RilletHQ is creating an entirely new category of finance infrastructure. With Rillet, the ERP becomes the harness for the modern finance organization, where people and agents share the same financial data, apply the same accounting policies and controls, and work from a single, continuously updated view of the business. Agents perform increasingly complex financial work, while finance teams retain visibility, approval authority and a complete audit trail.
Thank you to our customers for believing in the mission and building the future of finance with us. We could not do this without you.
Thank you to the Rillet team. As I say often, building Rillet is our own version of sending rockets to Mars. It is incredibly difficult. You make it look easy.
Finally, thank you to our investors. To ICONIQ for leading the round and to our existing and new investors for building with us. @sequoia , @a16z, Sequoia Global Equities, @BainCapVC, @oakhcft, @BatteryVentures, @FirstMarkCap, @scalevp, and @creandum.
Back to work :)
Today, we're excited to announce that we're leading Dash Bio's $30M Series A.
Drug discovery has never moved faster, but turning a promising molecule into an approved medicine still relies on manual, hourly-priced work with timelines measured in months. Dash is changing that, starting with bioanalysis: the lab testing that measures a drug's safety and efficacy in preclinical and clinical samples.
Through custom robotics and proprietary software, Dash is reducing turnaround times from months to days while offering upfront pricing and sample-level transparency the industry hasn't seen before.
In less than a year since launch, Dash has signed more than 30 customers, including four of the world's top 25 pharmaceutical companies.
Led by CEO Dave Johnson (former Chief Data & AI Officer at Moderna), COO Ander Tallett, and CSO Ely Porter, this team has lived the problem they're solving. We couldn't be more excited to partner with them.

Today, @candid_health announced a $120M Series D.
Medical billing is a $280B industry barely touched by real innovation since its software was built. Nick Perry and Doug Proctor built Candid to change that – pairing deterministic rules with agentic AI to automate the end-to-end claim lifecycle.
The results: Touchless Claim Rates as high as 97%, 6x/3x/2.5x consecutive years of revenue growth, and just one regrettable customer churn in seven years.
In our conversation, Nick and Doug discuss why billing systems are a black box, how they engineered that Touchless Claim Rate, and what it takes to stay ahead of changing insurance algorithms.

We're pleased to announce our co-leadership of Cordant's $8M seed round, as the company emerges from stealth as the command center for financial infrastructure.
Money moves in real time, but the visibility to understand that movement still depends on fragmented, manual reporting. Failures rarely happen inside a single system – they happen in the seams between banks, processors, ledgers, and compliance tools, where no single product is watching. Cordant is building the connective layer that closes that gap, ingesting and contextualizing signals across systems to create a shared operational reality institutions can trust.
As institutions look to deploy AI into payments and back-office workflows, that kind of governed context isn't optional – it's the foundation. We're honored to partner with Eric Rosenthal and the team as they build it.

Nurse practitioners didn't reach the mainstream through a single reform – it took decades of state lobbying, court rulings, reimbursement policy, and clinical evidence before NPs became a third of the country's prescribing capacity.
In his latest piece, Venture Partner Duncan Greenberg traces that history and draws out what it means for clinical AI, which is fighting many of the same regulatory and legal battles NPs did: practicing ahead of legal clarity, navigating a state-by-state patchwork, and ultimately depending on reimbursement policy to determine how widely it gets deployed.

.@chaidiscovery announced a $400M Series C, valuing the company at $3.8B – capping a run of momentum that includes a new collaboration with Novartis on AI-driven antibody discovery, alongside existing partnerships with Pfizer and Eli Lilly.
Together, these deals point to a real shift: AI-driven drug discovery is moving from research promise to deployment inside the world's largest pharma and biotech companies.
We sat down with co-founders @joshim5 and @jackdent to talk about that shift, and what it takes to build a platform company in one of the hardest problem spaces in science.

We are proud to announce that Oak HC/FT led a $25M Series A in Corner Health, bringing their total funding to $32.5M.
An estimated 100 million Americans lack access to a primary care provider – not because clinicians do not exist, but because independent practice has become structurally untenable.
Corner built Cora to change that. Cora is an AI-native practice operating system that automates brick-and-mortar clinic operations, enabling Nurse Practitioners to own and operate primary care clinics with zero administrative staff.
The results speak for themselves: clinicians on the platform spend two to three times more time with patients than the industry standard, maintain an average 4.9-star patient rating, and earn $30,000 to $80,000 more annually than their employed counterparts.
Congratulations to Lava Sunder, Anne Gifford and the entire team.

Stablecoins aren't a crypto story. They're a story about the infrastructure of global commerce.
In his latest piece, Oak HC/FT Partner Oivind Lorentzen explores how stablecoins have shifted from crypto trading instruments to the connective tissue of global B2B payments – and why the companies that make complexity disappear will define the next decade of cross-border finance.

We're proud to announce that Oak HC/FT led @StepfulTraining's $55M Series C – and we couldn't be more excited to double down on Carl Madi and the team.
Carl turned a labor crisis into a healthcare workforce engine: a 5-month certification track (vs. 2 years at community college), 22,000+ graduates in 2025, and partnerships with 35 health systems.
In this interview, Carl details how Stepful is utilizing AI to solve the projected shortage of millions of healthcare workers and why the future of vocational training lies in a decentralized, skill-based model.

We're thrilled to welcome John Maraganore as an Advisor to Oak HC/FT.
John is one of life science industry’s most influential architects – best known as the founding CEO of Alnylam Pharmaceuticals, where he spent nearly two decades turning RNA interference from a risky lab concept into a multi-billion-dollar global commercial reality.
In our latest post, we sat down with John to hear his perspective on where AI is – and isn't – living up to the hype in drug discovery, why hands-on founders still have a decisive edge, and what it really takes to believe in a technology before the rest of the world does.
