One of the best feelings in investing is when you discover that two people that you think incredibly highly of are actually working together

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.

I'm noticing a thing where 34 year old VCs text and email in all lower case to appeal to 22 year old founders – it is not an accident, it is calculated

Today I’m launching @Valkyrie_vc - a $45M early-stage fund investing in AI, infrastructure, and critical industries. Grateful to the founders, partners, and friends I’ve worked with along the way. You’ve truly shaped how I invest and why I built Valkyrie. To the founders: Valkyrie was built for you. To partner with you. To build what matters. This is our new frontier. Let’s build it. Thank you to @_pheebini at @Forbes who captured the story → forbes.com/sites/phoebeli…

Awesome work by the @streamfold team!
ClickHouse@ClickHouseDB

Can you 4x OTel thoughput with Rust? Meet Rotel: pushing 460K spans/sec/core (vs 130k) The @streamfold team told us how it works -> clickhou.se/4rju9en ClickHouse is fast at ingesting OpenTelemetry data - so fast that ingestion layers sometimes struggle to keep up. The OTel Collector can be resource-intensive, and at petabyte scale, every CPU cycle counts. Rotel is a lightweight OpenTelemetry collector implemented in Rust that can 4x throughput vs the standard OTel Collector, while dramatically reducing CPU overhead. How? By diving deep into Rust's threading model, resolving allocator lock contention, and reengineering JSON serialization with RowBinary encoding to stream data efficiently into ClickHouse. At 460K trace spans/sec per core, Rotel makes OTel as efficient as ClickHouse.

Life update - I just dropped out of northeastern to join @withdelphi full-time. I grew up watching my immigrant mom work long hours, never complain, and sacrifice everything so I could have a chance. Her dream was simple - for me to graduate, get a stable job, and live a life better than hers. But the last five months changed everything. March - I met @anneleeskates for the first time. June - Anne offered me an internship at Parable, and I moved to San Francisco. August - I met Robert and @daraladje September - I joined Delphi as a growth intern. October - I accepted a full-time offer and officially dropped out. Coming to San Francisco changed my life - there’s something magical about being surrounded by people who genuinely believe they can change the world. Before I made the decision, I called my mom. She didn’t yell or cry - she told me to go all in. To chase the dream she never had the chance to. Five months ago, I was just a student sending cold emails. Today, I’m building full time at a company I truly believe in. Thank you Anne for opening that first door, and Dara and Robert for taking a chance on me. And to my mom - I’ll make sure you never have to work another day. goal: retire mom in 3 years locked in.
