[Eric Glyman @eglyman]

Introducing Stack.

The AI operating system that lets accounting firms take on more clients without hiring. Learns your firm's process, runs the close, posts the journals. Fully auditable.

We’re living through the biggest shift in accounting since the spreadsheet.

[BoxGroup @BoxGroup]

@AlexRWendland @joinadaptive @felicis @BainCapVC Here we go!!

[Alex Wendland @AlexRWendland]

Excited to share Adaptive Innovation’s (@joinadaptive) $50M Series A led by @felicis and $10M Seed led by @BainCapVC.

Adaptive is an AI-native healthcare provider rebuilding the way care is delivered in America, starting with home health

[Forus @forushq]

Today we’re introducing Forus and announcing $160M to build the foundation for modern medicine.

Science should be the only limit to medicine. Today it isn’t. Drug discovery is moving faster, but the system that turns it into real-world treatment isn’t.

We’re already working with early customers in semiconductors, batteries, and advanced materials. More below.

[Rogo @RogoAI]

Today, we’re announcing our $160 million Series D funding, led by @kleinerperkins, with participation from @sequoia, @ThriveCapital, @jpmorgan, and @khoslaventures.

35,000+ financial professionals. 250+ institutions. One platform, purpose-built for finance.

Thank you to our clients, our team, and our investors for their support as we continue building to raise the ceiling for what finance can accomplish.

[Haladir (YC W26) @Haladirofficial]

We at @Haladirofficial just raised our seed round, bringing our total amount of funding to $4.3M to build operational superintelligence. Led by @BoxGroup and @SusaVentures, with participation from @seedtosunflower, @Valkyrie_vc, XPRESS Ventures, and various angels, with prior round funding from @ycombinator and @svangel, and our first believer, @Joshuabrowder.

[Apurva Shrivastava @apurvas96]

I'm excited to share that @getavoca has raised over $125M across Seed to Series B at a $1B valuation, backed by Kleiner Perkins, Meritech, General Catalyst, Amplify, and more to build AI agents for the services economy. Thank you to @FortuneMagazine for the exclusive cover.

[Michael Truell @mntruell]

Excited to partner with the SpaceX team to scale up Composer. A meaningful step on our path to build the best place to code with AI.

[Antioch @antiochrobotics]

We’ve raised $8.5M in seed funding, valuing Antioch at $60M, to build the simulation platform for physical autonomy.

The raise was led by @Category_VC and @A_StarVC, with participation from @MaCVentureCap, @AbstractVC, @BoxGroup, @IcehouseVenture, and angels.

Antioch brings robotics and autonomy development entirely into simulation. Teams build, iterate, and test their full autonomous stacks in a single platform, accelerated by agents with native understanding of 3D environments.

We're doing for physical autonomy what coding agents have done for software development. When the entire development loop lives in simulation, engineers and agents can reason about a robotic stack the same way they reason about a codebase: run it, observe the result, and iterate.

The funding will go toward further expanding the engineering team, the core simulation infrastructure, and our new agentic framework.

TechCrunch covered the raise and what we’re building: https://t.co/g5Yk1SzjSe

If you’re an exceptional engineer interested in redefining autonomy development, we’d love to chat: https://t.co/RIDLmGI92U.

[Rogo @RogoAI]

We are introducing Felix.

Felix is a purpose-built agent for high finance, designed for long-running, complex workflows and capable of producing decks, models, and documents end-to-end.

Felix executes so you can focus where it matters.

[Warp @warpdotdev]

You can now run any CLI agent with first-class support in Warp, including Claude Code, Codex, OpenCode and Gemini CLI.

• Vertical tabs
• Notifications when they need you
• Integrated code review
• Remote control from mobile
• Rich input editor

[Spencer Mateega @spencermateega]

For most of history, expertise was scarce, constrained by time and reach: one person, one career, one lifetime.

Now, for the first time, we can encode, evaluate, and scale it.

We believe the wisdom that once took a lifetime to build shouldn’t take a lifetime to find.

Today, we’re excited to announce that @AfterQuery has raised a $30M Series A at a $300M valuation and that we’ve since surpassed $100M in annual revenue run rate, to build the data layer of professional AI.

[Adit @aditabrm]

Today, we’re setting the new standard for complex document extraction.

Introducing Deep Extract. It utilizes an agent harness approach that repeatedly iterates and verifies outputs until they are at human-level accuracy.

[Cameron McCord @CameronLMcCord]

Ambition is timeless. Tools are not.

Today we are announcing an $80M acceleration round at a $1B valuation led by @foundersfund, with participation from @sequoia @generalcatalyst @Lux_Capital @RedGlass @lightspeedvp Avenir, and @Haystack.

In the last year, we grew revenue 7x, added some of the world’s most serious hardware enterprises, and built over twice the new product surface area than in our prior two years combined.

The most ambitious and fastest-moving hardware teams choose Nominal, from aerospace to energy, and automotive to defense, because it helps them learn faster and scale more efficiently. Our mission is to bring that advantage to every team building in the physical world. For those not yet using Nominal, we hope to have the opportunity to earn your trust and work hard for you and your company soon.

All systems Nominal. 🚀

Thank you @business and @EdLudlow for sharing out story. And @traestephens and @zebulgar for doubling down.

[ZC25 @zachcohen25]

I’m excited to share that Ease Health is coming out of stealth with a $41M Series A led by @a16z, alongside @AbstractVC, Sunflower, F3, and @BoxGroup, to build the AI-native operating system for behavioral health.

Behavioral health runs on some of the most fragmented infrastructure in healthcare.

Providers are forced to stitch together EHRs, billing systems, CRMs, schedulers, documentation tools, and compliance workflows just to operate. We started Ease because this is not a tooling problem. It is an architecture problem.

So we rebuilt the system from the ground up.
Ease is a single platform where AI is not a bolt-on. It is foundational.

-Documentation is handled by an ambient AI scribe.
-An AI voice agent can manage intake and scheduling.
-Our CRM auto-enriches leads and logs activity automatically.
-Front desks can instantly match patients to the right provider.
-Charts are audited continuously.
-Utilization review and prior authorizations can run autonomously.

When data is entered once, it flows everywhere it needs to go across clinical records, billing workflows, and reporting.

One through-line of truth across the entire organization.

Since launching, we have grown quickly and now support hundreds of behavioral health providers across inpatient, outpatient (IOP, PHP, MAT), and residential.

The behavioral health crisis is not a demand problem. Providers are buried in manual documentation, claim denials, compliance friction, and disconnected systems. We are building the system designed to remove that burden.

We are grateful to Andreessen Horowitz for leading this round, and thankful for the support of all of our investors and partners who believe in rebuilding healthcare infrastructure the right way. Your conviction and partnership mean a great deal to our team.

[Basis @trybasis]

We've raised $100m at a $1.15b valuation from @Accel, @GVteam, and existing investors to accelerate deployment of the most capable and accurate accounting agents across CAS, tax, audit, and advisory.

Basis is used by 30% of the Top 25 accounting firms and dozens more across the Top 150.

Today we're announcing the first accounting agent to complete a business tax workbook end-to-end.

Our focus on production-grade, long-horizon agents means that 12 months from now, the work Basis handles will make even this look routine.

We're looking for a few very intense people who want to build at the frontier.

[Nimi Katragadda @nkatragadda]

Falconer is building a structured knowledge graph for the AI era. Excited for @capitaltruist and the team to launch it publicly, and lucky to be part of it!
