$550M Series D led by @Accel. $5.55B valuation. One year into our U.S. expansion, we’re doubling down: accelerating across America and building AI with the lawyers who use it every day. Grateful to our customers, partners, and team. More: legora.com/blog/series-d

I’m excited to introduce Proximal with @MatternJustus and @navidkpr We believe that many companies work on training data, but almost all of them are approaching it the wrong way. Historically, the biggest capability jumps came from engineers inventing scalable ways to collect domain specific data, and not from scaling up manual labor. Our core belief at Proximal is that the data needed for progress will not come from a recruiting firm or a talent marketplace, but a research and engineering organization that treats data as a problem which deserves the same level of rigor as work on training algorithms and model architectures. We think that this is the most impactful work towards agents that can autonomously solve complex technical problems, and intend to share our research and progress in the open. Since starting last year, we've grown incredibly fast and have made great technical progress. We are backed by top investors and angels from OpenAI, Anthropic, Thinking Machines, xAI, Meta Superintelligence, Google Deepmind, Cursor and Cognition. We're expanding our team and hiring researchers & engineers in San Francisco! If you want to work on data and RL for long-horizon coding agents, reach out!

EXCLUSIVE: startup Simple AI has raised $14M to help customers like Omaha Steaks boost sales with AI phone reps. Is AI ushering in a voice revival? We talked to founders @catheryn_li and @Zach_Kamran -- both former YC staffers -- about what's going on. upstartsmedia.com/p/simple-ai-vo…

Excited to announce that @simpleailab has raised a $14M seed round led by @firstharmonic. For the past year, we’ve been building AI voice agents to transform direct-to-consumer sales. We fundamentally believe that voice AI is the future of all B2C calls.

we built our own background coding agent at ramp: it's called inspect its powered by @opencode and @modal, and works with all the frontier models it has a cloud hosted version of vscode, chromium, and terminal. has all the tooling and skills a ramp engineer would have, and is blazing fast we're basically giving every ramp builder infinite laptops so they can yolo their most ambitious ideas at zero marginal cost with the biggest models we can find @zachbruggeman @monasticpanic @nzgb

Announcing Artie’s $12M Series A. When Robin Tang and I started Artie, the idea was simple: make it easy to deploy real-time streaming pipelines. Streaming pipelines used to be something only a few companies could afford to build. Guaranteeing transactional integrity, handling schema evolution, recovering from failures, and keeping latency low at scale is hard. Most teams limp along with brittle systems. But today, with AI systems that make decisions, trigger workflows, and interact with customers, stale data isn’t just slow - it’s incorrect. Real-time data is becoming non-negotiable. Today, companies like ClickUp, Substack, and Alloy, are processing 700B+ rows of data annually with Artie to power AI/ML workloads, customer-facing analytics, and operational systems. @artie_labs is a fully managed real-time data streaming platform. We move data across systems in real time - so teams can rely on fresh, accurate data to power AI products - without building or maintaining streaming infrastructure. We raised this round to double down on a simple belief: the next generation of data infrastructure will be streaming-first. Huge thank you to @daltonc and @Standard_Cap for leading the round, with continued support from @ycombinator, @PathlightVC, and incredible angels including @arashf, @bennstancil, @chrisbest, @charleshearn, and @lennysan. I also want to thank our team, customers, and partners for supporting our mission. And thank you to Chris Metinko and @axios for capturing the exclusive story. P.S. - If you want the same streaming infrastructure that Netflix and DoorDash have, but want to skip the multi-year build - reach out.
