We believe voice is the most natural way to interact with intelligence, so we created Dessa, the most authentic full-duplex speech model ever built. Talking with it feels like talking with a person…full of emotion, nuance, pauses, and a natural cadence. block.xyz/dessa

Excited to introduce @Cosign: the curated professional network for the startup community: cosign.co Our goal is to create the following: - A comprehensive startup directory of investors, companies, and operators, including what they worked on and who they worked on it with. - Cosign graph: Who shaped your career? Who were you actually in the trenches with? Who would work with you again? Who thinks you’re someone to watch? - Durable reputation: Great endorsements happen every day on X and disappear into the feed. Cosign attaches those signals permanently to people and companies. - Discovery: Who are the best fintech angels? Which AI companies should I watch? Who are the best designers? - Intent network: Privately signal “I’d invest in them,” “I’d hire them,” “I’d work with them,” or eventually even “I’d acquire this company.” Match people when interest exists on both sides. Imagine if Wikipedia, LinkedIn, and OG AngelList had a baby. Though Cosign is a community, not a business. In order to join, you need to be cosigned. Or you can apply directly. David Booth and I started this idea 7 years ago but didn’t have the firepower to make it work. Now we do. No one has really touched LinkedIn in 20 years. Excited to take a swing. cosign.co

Announcing The Horowitz Andreessen Academy. The internet made it possible to know anything. AI makes it possible to do anything. The best assignments now are problems so hard they cannot be solved without AI. The Academy courses follow the same logic and will be taught by world-class leaders. The most talented young people today rarely have their sharpest peers within walking distance. Their network is online. Those networks are real, but they're thin. The next generation will not be taught the way the last one was. The Academy is built for that world, and it begins in San Francisco. If you're young, hungry and love building things, apply for the Founding Class Fellowship.
Today, we’re launching an ambitious new school called The Horowitz Andreessen Academy. Based in San Francisco, The Academy serves the most promising young high school graduates. We think this can be an elite institution that attracts top tier talent. One that prepares students for the future rather than remaining stuck in the past. The #1 goal is to help students learn to build, which is the most important skill in the AI era. They'll learn primarily by pursuing their own projects, either individually or in groups. There are classes and guest lectures, too, from some truly amazing people who have built modern-day Silicon Valley. The Academy is designed as a network, since that’s the reason students go to school in the first place. Core to that network are our 10 Founding Partners: Anduril, Anthropic, Coinbase, Google, Meta, NVIDIA, OpenAI, Palantir, Replit, and Stripe. The network includes over 50 hiring partners and over 200 speakers and mentors. To join as a hiring partner or faculty member, you can apply on our website. We raised $42M in funding led by @a16z. I'll be CEO and @pmarca and @eriktorenberg will join me on the board. Applications are open for our Founding Class Fellowship, which will be one year and tuition-free. Eventually, pending regulatory approval, we plan to offer a two-year program that charges tuition, similar in cost to an elite private university. We're looking for the most unusually ambitious young builders on the planet. Come join us in San Francisco: theacademysf.com/

BREAKING: a16z Launches The Horowitz Andreessen Academy with $42M in Funding Yes, a school. The Academy is an unaccredited, residential alternative to a 4-year degree in San Francisco, led by Founder & CEO Gagan Biyani (@gaganbiyani) (Udemy, Maven). Marc Andreessen (@pmarca) & Erik Torenberg (@eriktorenberg) are on the board. Investors include Adam D'Angelo, Tobi Lütke, Tony Xu, Fidji Simo & Shyam Sankar. Applications open today for a Founding Class of roughly 50 students, starting Fall 2027. 1 year, no tuition, admitted on proof of work. Anthropic, Anduril, Coinbase, Meta, NVIDIA, OpenAI, Palantir, Replit & Stripe are Founding Partners, with 30+ hiring partners behind them. We cover: › The $42M raise and the runway behind it › Portfolios, interviews and IQ testing in admissions › 75% to 80% project time and weekly pod check-ins › Tuition, partnerships and equity as the 3 revenue lines › Why the Academy is telling fundable 17-year-olds to wait "The big difference between going to the academy and going to college is we are not gonna prioritize your grades. We're gonna prioritize proof of work." 𝐓𝐈𝐌𝐄𝐒𝐓𝐀𝐌𝐏𝐒 (00:00) Gagan Biyani, Founder & CEO of Horowitz Andreessen Academy (01:01) Why this Academy is different from college (04:44) Started his first company at age 13 (08:30) Building a school for Silicon Valley (11:55) Raising $40M for a School (14:06) "You Did What?" - Proof of work over grades (19:08) Should young builders really start companies?

I agree, you need topics per-bot please!
First impressions of Grok Bot: - With Grok Bot you don't juggle threads, you juggle named/personified agents. This seems like a ~fine mental model: hire a team of specialists that can talk among themselves to get work done. - But this creates some problems when you want to multitask within a single agent. If you give an agent a chunky task that takes a long time, you don't really want to interrupt it or distract it mid-task. I haven't found a way to queue messages. In a thread-first world, you'd just spin up another thread. (Technically there's a "create thread" button on each message bubble, but it feels intentionally buried and not recommended.) - I'm biased towards using threads to create "context bubbles" for discrete tasks and prevent context contamination. But every Grok Bot agent uses a single long-running thread, and it's not obvious where discrete tasks get chunked or compacted. If I'm working with sensitive data, this forces me to create copies of the same agent so I can force context bubbles around sensitive tasks. - I'm not sure if most people will prefer a single omni-agent that juggles threads and projects (Jarvis-style), or if people actually want to build and manage multiple discrete agents that coordinate with each other. Tradeoffs in both directions, and maybe you end up needing both models for different audiences. - The agents themselves are capable and surprisingly dynamic. They are good at responding quickly, keeping you updated iMessage-style as they make progress on long tasks, and configuring themselves on the fly (or even reacting appropriately if you adjust their configuration manually). - One of the surprising details that Grok Bot hides is all the thinking steps/tool calls. Almost every other AI agent exposes these, including ours at Notion. When we designed Notion Agent last year, we tried to remove these steps for the sake of simplicity, but our customers demanded we add them back both because they serve as a useful loading indicator (it's entertaining to watch computers magically do work!), and because they can be used to spot the model going off track so you can jump in and pause/steer. But I suspect model progress (speed + quality) in the last year is making both of those points less relevant, so maybe it's okay to hide more of the underlying noise from the transcript. Grok Bot agents are still good about sending mid-task progress update messages (I think this is all Grok 4.6?) - The idea of starting a new chat with multiple agents (aka a channel? project? workspace?) is pretty nice, but agents are still a bit dumb and they go in loops talking to each other before finally shutting up. Maybe there are some prompt-fu opportunities to make them chill out. - It's been a great experience delegating agents to work simultaneously across the cloud computer, my local machine, and Cursor cloud coding sessions. The system works really well, and I've been able to throw fun tasks at the agents without any major problems. - Consolidating skills, MCPs, connectors, and more complex tools behind a single "Plugins" concept feels right. It looks like everyone on the frontier is coming to the same conclusion. - No model picker feels weird, but only because I'm used to fiddling with models/effort levels per task in all my other coding tools. Presumably Grok Bot agents are doing some routing under the hood? Making this + thinking tokens + tool calls opaque means you really have to have a "model take the wheel" mindset when using this app. Again, probably long-term right, but short-term feels uncomfortable (giving up control). - The UI is nice. Mobile app is nice. Cursor mobile app is nice for code sessions. It just all feels...nice. Kudos to the design team for nailing the visual polish and small details. The motion design for the agent avatars is s-tier. - Yet this shape of tool is becoming so common across so many companies (and open source!) that I don't really know how people are going to justify one $200/mo subscription vs. another. I suspect in the short term it'll come down to vibes/tribal affiliation/token subsidization, at least until there is some bigger differentiator at the capability level. - As an experiment, I told my Grok Bot agents to switch to using a Notion database for the memory layer. They had no objections and I've watched them create ~20-30 pages in my Memory database. This feels really noisy, and I'm not sure what the impact on quality will be, but it's cool that the agents had no problem adapting to work the way I want. Whether they're actually using the database correctly under the hood, I can't tell...the whole system is quite opaque. - Grok Bot is an odd name for an app that wants you to coordinate work across lots of bots. - My hunch is most people don't actually have that much stuff they need to automate in their daily life. I'd love to see retention graphs!

We raised $8m to build self-healing software. In 2026, software moves fast. But monitoring and observability are still manual and slow. @sazabi is a next-generation observability platform for fast-moving engineering teams. Not another AI SRE. Not another LLM observability tool. A new, general solution to observability that works for any workload (including agents) and leverages AI for maximum speed and automation. Time to suit up.
