If you've logged into Claude through your work account, you've used @WorkOS & probably didn't know it. WorkOS is the enterprise identity layer powering some of the biggest names in AI: @AnthropicAI, @OpenAI, @perplexity_ai, @xAI, & more. They handle the SSO, authentication, and security infrastructure that turn a consumer product into a secure, enterprise-ready one. On the heels of co-leading their Series C, @aranum sat down with founder & CEO @grinich to discuss how the security & identity infrastructure we've relied on for decades wasn't built for a world where AI agents act autonomously within your systems, & how WorkOS is building the answer. 🎬 Watch their conversation below to learn more about how WorkOS is defining identity infrastructure for the agentic era. 👇

To close out this year's Hypergrowth Engineering Summit, we heard from 3 AI leaders on what it takes to get agents to production: - @jakeserval, CEO & Founder @getserval spoke on safely deploying agentic reasoning in mission-critical enterprise workflows. - @mfateev, CTO & Founder @temporalio talked about why most of what breaks in production isn't your business logic. It's the platform underneath it. - @GSalakirov, Head of Engineering @wetravel discussed why the engineering discipline that makes humans productive makes agents productive too. Thank you to everyone who joined us today! Recap coming soon. 🌟🙏

OpenAI's internal data platform handles 1.5 exabytes of data, 90k datasets, & 5.5k daily users. Give it a revenue goal & it can surface an expansion strategy from patterns in the data. @jai_das sat down with Emma Tang, Head of Data Infrastructure at @OpenAI, to break down how her team built the data platform from scratch & runs it at our 5th annual Hypergrowth Engineering Summit. Follow along for more highlights!

Up next at our Hypergrowth Engineering Summit: @sarahmsachs, Head of AI Platform Engineering at @NotionHQ, takes the stage on Efficient Agent Design in the Token Era. 🎤 Model pricing is structurally hostile to anyone who isn't a hyperscaler. New model versions can silently consume 3x more output tokens. Successor models arrive 40% more expensive, while predecessors get deprecated in four months. And the frontier labs are subsidizing their own competing consumer products. So what do you do? Sarah's answer is to be the Switzerland of AI models. At 100M users & trillions of tokens per month, Notion runs infrastructure against multiple providers simultaneously, routes cheaper models for the majority of traffic, & treats model selection as a continuous optimization problem. Stay tuned for more!

LIVE from our 5th annual Hypergrowth Engineering Summit: Closing the Agentic Loop! Sapphire’s David Carter kicked off the afternoon before introducing our first speaker…📸 @felixrieseberg Head of Claude Cowork & Code Desktop at @AnthropicAI who joined @CGao to unpack what it actually takes to turn a coding agent into a coworker. Many lessons learned, including 3 tips for those building: • The model isn't the bottleneck because the capability already outpaces what most users extract. It takes real skill to prompt a model in a way that uses all of its capabilities. • There's a real gap between agents you supervise & agents you can walk away from. The path forward is defining what the agent can & can't reach. • The best way to prompt an agent is to treat it like an intern. We’ll be capturing highlights from throughout the rest of the day. Be sure to follow along!

Congrats to @yotamseg & the @cyera_io team on their $600M series G. 👏 We've backed Cyera since co-leading their Series D, when legacy security infrastructure was buckling under the shift to cloud, and GenAI was introducing an entirely new set of risks. Today, 68% of organizations can't distinguish between human and AI agent activity in their own systems. Cyera is building the infrastructure layer to fix that. Proud to continue our partnership.

5th Annual @SapphireVC Hypergrowth Engineering Summit is NEXT WEEK & you won't want to miss this year's theme: Closing the Agentic Loop. All-star speaker lineup of founders, CTOs & AI eng leads from @AnthropicAI, @OpenAI, @NotionHQ, @WorkOS, @getserval, @reactorworld, @temporalio & more! 📍 SF | June 11 Space is limited, apply to attend today! 🔗: na2.hubs.ly/H05vfRn0

In just 3 weeks, our 5th annual Hypergrowth Engineering Summit is coming to SF on June 11th! In 2025, we brought together 220 CTOs, VPES, heads of AI, technical founders, & leaders from some of the most impactful hypergrowth startups & enterprises on the planet to explore the future of engineering in the age of AI. This year, we're going deeper across 4 critical fronts: frontier reasoning & multimodal intelligence, the recursive software engineering loop, agent engineering & reliability at scale, & generative UX & the human-agent interface. Space is limited. Apply to attend: na2.hubs.ly/H05Fx140

Congratulations to @immad & the @Mercury team on their $200M Series D! We first backed @Mercury over 5 years ago, when @plevine, @rajeevdham, @JasonRBrooke & the team believed it would become the defining banking platform for tech founders. Today, with 300k customers, including 1 in 3 U.S. startups, they've delivered on that vision. We're proud to continue the journey alongside them. Read more: cnbc.com/2026/05/20/fintech-…

The most successful vertical AI companies won’t just build AI products, they’ll become the systems entire industries run on. That shift is already starting in markets often overlooked: think medical billing, auto lending, freight logistics, tax accounting. These industries are fragmented, operationally messy, full of edge cases, and difficult to sell into, which is exactly what makes them defensible. The companies winning here aren’t stopping at workflow assistants or AI features. They’re going deeper: embedding into approvals, compliance, integrations, exceptions, & ultimately the labor & services budgets behind the work itself. Over the past 2 years & hundreds of pitches, @CGao & @adityareddy97 have been tracking what separates vertical AI products from vertical AI systems, why overlooked, operationally complex markets may produce the most durable AI companies.

On the heels of the AI Agent Conference in NYC this week, one topic took center stage: the AI agent era has arrived. @jai_das shared his perspective on the shift underway, from which functions agents will transform first, to the real cost pressures of running them, to the bifurcation forming between AI-native startups and those trying to catch up.

Congratulations to Sendur Sellakumar, @tshiran, & the @dremio team on joining the SAP family! 👏👏👏 When we first partnered with Dremio, the team had a bold thesis: the explosion of enterprise data would outgrow the traditional data warehouse, & that a faster, more open way to access & analyze it was long overdue. They were right. Dremio grew to be an open, high-performance data lakehouse platform built to accelerate agentic AI, serving some of the world's largest enterprises, including @Shell, @TDBank_US, & @Michelin. Joining SAP, a Sapphire Ventures LP, is a milestone achievement for Dremio & a natural next chapter. Together, they will unify SAP & non-SAP data to power agentic AI.
