Three announcements from our keynote at Compile, including how we're training a new model with SpaceX.

SpaceX has exercised the option to acquire @cursor_ai in an all-stock transaction with the goal of building the world’s most useful AI models. For the past few months, SpaceXAI has been jointly training a model with Cursor, which will be released in Cursor and Grok Build soon. We look forward to working closely with the Cursor team to advance our frontier AI capabilities

We're launching @niteshiftdev – the full-stack cloud for coding agents Verification is the new bottleneck. Software teams can now define their dev environment and verification tools once. Then run any frontier agent in the cloud: Claude Code, Codex, or OpenCode

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.

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

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

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. forus.com/blog/forus-ann…

excited to finally emerge from stealth

Introducing Altara: the scientific intelligence platform for the physical world. Today @evatuecke and I are excited to announce our $7M seed led by @GreylockVC, joined by @Neo, @BoxGroup, @Liquid2V, and angel investors including @JeffDean and leadership from OpenAI & AMD. We’re already working with early customers in semiconductors, batteries, and advanced materials. More below.

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.

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.

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. fortune.com/2026/04/27/avo…

We just published @Plaid's 2025 Shareholder Letter. 2025 highlights • >$500M ARR (~40% YoY); profitable; strong margins • >1m new connections every day • New products >20% of revenue growing at >90% • Major progress in Credit Scoring and Fraud Analytics • AI has accelerated everything. >400 AI companies built on Plaid in the last year. Lots more to come in 2026! And as always, feedback welcome. Would love to hear from y'all. plaid.com/2025-sharehold…

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.

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: techcrunch.com/2026/04/16/thi… If you’re an exceptional engineer interested in redefining autonomy development, we’d love to chat: antioch.com/careers.

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.

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 Download Warp for free today.

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.

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. More below:
