AI has transformed how video is created. We think the next wave is about understanding it. Over the past few years, we've seen remarkable advances in video generation, editing, avatars, and creative tooling. An increasingly important problem is teaching machines to search, analyze, reason over, and extract insight from video - across massive libraries and live streams alike. We're calling this video intelligence, and we're actively looking to back founders building here. We're most excited about companies pushing on the core capabilities: - Video-native models - multimodal embeddings, temporal reasoning, and retrieval built specifically for video rather than adapted from image or text - Real-time and large-scale pipelines - infrastructure for processing, indexing, and querying video at the speed and scale enterprises actually need - Agentic and reasoning layers - systems that don't just retrieve clips but answer questions, surface anomalies, and take action on what they see The models and infrastructure to make this real are appearing to be crossing a capability threshold right now. Multimodal foundation models are maturing, storage costs have collapsed, and enterprises are sitting on years of unstructured video with no way to use it. That infrastructure unlocks a wide range of applications including media and sports workflows, security and physical operations, enterprise knowledge management, advertising analytics, robotics, and consumer products, where video has historically been dark data. If you're building in video intelligence at the model layer, the platform layer, or in a vertical application, we'd love to talk!

I’m excited to share that we’re leading the Series B of @reductoai and I’ll be joining the board. The demand for structured document processing is growing rapidly. Reducto is the magic spell that “turns large solid objects into pieces”. Hundreds of startups/enterprises rely on Reducto to turn long-form docs into smaller chunks. Here’s how it works for some “tough” documents, starting with my husband’s wedding vows 💍

I've been lucky enough to try the Windsurf Editor in preview and it's truly magical. The @codeiumdev is building magical AI experiences and this is only the beginning.
Today we’re excited to launch the Windsurf Editor - the first agentic IDE, and then some 🏄 In Windsurf, we have given the AI a previously unseen combination of deep codebase understanding, powerful set of tools, and real time awareness of your in-editor actions. The result? A magical experience we call Cascade, the evolution of chat that keeps you truly in the flow state. We essentially took the best of both copilots and agents - the collaborative nature of copilots and the ability to be independently powerful like an agent - to create the world’s first collaborative agent, which we are dubbing a “flow.” One important note - everyone can use this today. No waitlists, no invite only, no crazy rate limits. General access, as it should be. Check out what Cascade is able to do in the thread below. #windsurf #cascade

Lucky to have you on the team 🔥
life update: I decided to forgo college this fall to join @a16z full time. I’m beyond excited to be part of the New Media team. Our goal is simple: help the firm and its portcos tell their stories, and push the frontier of what’s creatively possible. This path hasn’t been straightforward. Balancing school and work was hard and extremely lonely. But along the way I’ve also found some of my closest friends, worked with people I grew up admiring, and built memories I’ll carry forever. Dropping out is a scary sentence to write. At the same time, I feel an undeniable pull toward this work. It excites and challenges me every day. Here's to a new chapter.

Fantastic pod with @alighodsi. A key lesson on culture/996/working hard: Strong performers operate best when they feel like they have purpose and clear line of sight to making an impact. Folks then work hard willingly. It becomes a natural byproduct of wanting to see things through.
Ben Horowitz and Ali Ghodsi: How to Run a Billion-Dollar Business Ben Horowitz founded Loudcloud in the middle of the dot-com bust and sold it for $1.6 billion, then led Andreessen Horowitz from its founding to $46 billion in committed capital. Ali Ghodsi co-founded @Databricks, stepped in as CEO during a crisis, and led it to a valuation of over $100 billion. In this episode of “Boss Talk”, Ben and Ali join a16z General Partners Sarah Wang and Erik Torenberg to share founder war stories, how to hire and make deals, how to keep culture intense without burning employees out, and why founders should raise their ambitions even higher. 00:00 Boss Talk returns 01:01 Why Ali became CEO of Databricks 09:45 From academic to CEO 16:00 Radical candor feedback 19:10 Scaling intensity and culture 31:55 The Microsoft deal strategy 39:00 Setbacks and sealing the partnership 42:05 Building vs buying 54:55 Turning down acquisition offers 1:03:45 Key pivots, founding team legacy @alighodsi @bhorowitz @eriktorenberg @sarahdingwang

Companies like Bubble are not just “no-code” — they’re redefining what it means to code. When we code we’re feeding computers instructions, and countless abstractions make this “instruction feeding process” easier.
