We are growing so fast at Spellbook that we need a new person to lead Growth Analytics! $5k USD if you refer someone great that we hire. They should be passionate about growth, data and getting to the top of the mountain. spellbook.com/careers?ashby_…

We're proud to share that @FiveGuys has chosen @SpellbookLegal to accelerate their contract flow. GC Adam Aberra and the Five Guys legal team are running the forward-thinking legal infrastructure behind a global franchise network that spans 1,900+ restaurants across 29 countries. We’re honored to be supporting them as they scale and sharpen their work with Spellbook. This was a delicious announcement to make :)

@dbatura @XMoney

Today, we're releasing @XMoney to a subset of US Premium+ users to collect feedback and iron out issues ahead of a broader launch. As appreciation for being an early user, we're extending our internal perks to this group for a limited time. Notifications going out now!

Will it soon be legal malpractice *not* to use AI?

@TimDraper @DraperVC Congratulations!

I am so proud to announce the launch of DA8, another $300M we are putting to work into disruptive early-stage founders! 41 years in, and I love the job more every day. We relaunched @DraperVC 12 years ago. Since day one, we have continued to back founders who are willing to sound crazy. The ones who look at a broken industry, that hasn't been innovated on in 20+ years, and say, "I'm going to fix that, no matter what it takes." Over the history of Draper, we have been the first VC in companies like @Tesla, @SpaceX, Hotmail, @Twitch, @Skype, @Baidu_Inc., Bitcoin, @Coinbase, @Robinhood, @Oklo, @Polymarket, @XanaduAI, @iceye_global, @Colossal, and the list goes on. I remember the first time I met every one of those entrepreneurs, and the hundreds more we have funded over the years. At Draper, we look forward to funding more entrepreneurs who build unicorns and trinocorns (trillion dollar companies). What I've learned after four decades is simple. The greatest founders are those who feel that they have to do what they are doing. It was pre-ordained. Getting to help them and fund them early is the privilege of my work. To our new Limited Partners: we appreciate you for working with us on this important mission. We know it is only the boldest LP that sees the investment world as we do. To the founders coming to pitch us for DA8: we cannot wait to see the future you create. And to anyone building something the world isn't ready for yet, keep going. We are looking for you. Here's to DA8.

@YouPulseX Honestly: prompt diffs yes (skills in git), behavior diffs no (no eval harness yet). Just started running this kind of pipeline would also note that I'm learning in public 😃. @edith_h might have a sharper answer here.

@JoshSteinVC For the PR review agent, can the author see what changed between last week's prompt and today's behavior before acting on the comment?

Running my own little fleet of Claude agents — newsletter ingest, tweet drafts, code review on my PRs — has made one thing obvious: the prompt you shipped last week is often not the behavior running today. LaunchDarkly's AgentControl feels like the right shape of an answer. Excited to try it out!

Today, we launched @Rippling Automated Compliance, starting with SOC 2. We have a unique advantage here: we aren't telling you how to fix your stack, because we ARE your stack. device management, identity and access management, HR, performance management...

@kevaldesai Well played.. :)

@JoshSteinVC Ah!! So all this time, this is what they meant by "have your agent talk to my agent"????!!!!!

When your team is on Claude Code and needing to collaborate, the fastest handoff might not be Slack or email. Instead, try having one Code instance write an MD file with exactly what it needs, for another Claude to answer. TLDR: Machine to Machine > Trying to figure it out between people. 😃

Thinking about the current pace of change got me thinking about the old days. I started in venture capital in April 2004. Top 10 companies, April 2004: Industrials, oil, pharma, banks.. and Microsoft/Intel. Combined market value: ~$2.4T. Top 10 today: NVIDIA, Alphabet, Apple, Microsoft, Amazon, TSMC, Broadcom, Meta, Tesla and Aramco. 9 of 10 are tech. Combined value: ~$27.9T. NVIDIA (~$4.9T) is ~15x the value of the 2004 number one. And double the value of the 2004 top 10, *combined*. The game keeps changing. Faster, bigger, better. The one constant: be long on technology. The next decade or two are going to be incredible.

@a_protsyuk A great point. The MD file isn't the big unlock, its the agent-agent communciation. Especially for fixing issues and collaborating around code, humans in the loop just slows things down.

@MindTheGapMTG @AnthropicAI An excellent framing and agree entirely.

The pace at which @AnthropicAI is shipping new features for Claude Code is incredible. I've worked in software for 30 years and I’m struggling to think of anything comparable. Early AWS is maybe the only thing even close?

@alshrfi I love the "slow is smooth and smooth is fast" description. Agree. What's so interesting about gstack is that it doesn't even really slow you down. Running the pipeline is minutes, not hours or days.

Spot on. Speed without structure is just a faster way to run into a wall. 🧱 In dev, 'Slow is Smooth, and Smooth is Fast.' Investing that initial 15 mins in architecture isn't a delay—it's an insurance policy against future chaos. Efficiency is knowing when to stop typing and start thinking. 💻🚀

Anytime I've built something in Code *without* running it through the gstack pipeline, I've had to come back and rework it. Code is great but it also charges off half-cocked, solving whatever problem it thinks it sees, before asking if that's the *right* problem. gstack pushes you to take the time up front to ask "what am I actually trying to accomplish, what's the 10x version of that and what'll bite me later if I don't think about it now?" 10-15 minutes that saves hours of rework. Classic measure twice, cut once. And thank you again, @garrytan!

@leeschmidt123 I think that's correct. And the power of both gstack and AI in general - it lets regular/untrained people operate and build like experienced product builders. And at scale.

Maybe I'm not fully understanding the unlock here, but whenever I set out to build a feature - this is always how I work (that's how it was pre-AI and still today with AI assisted coding). I feel like some of these AI workflows just surfaced what good product builders have already been doing for years.

@AbdMuizAdeyemo Highly recommend checking it out! Quick version: a very thoughtful and well structured set of /skills, packaged together into a conductor pipeline that, in my experience, dramatically improve the quality of what you build.

@JoshSteinVC What is gstack repo really about?

@kranirudha 100%. Which is why the "write a comprehensive and detailed MD file" feels so powerful.

@JoshSteinVC Packaging all that context and passing along is the real pain.

@lmanchu Very cool. Which repo?

A few months ago, I worked on a solution to handle this kind of collaboration between agents and humans. Your approach is one I tried out earlier on. But it soon became clear that the real situation isn’t as simple as just agents interacting with each other – humans and agents both play a role in this process. In the end, my repository represents the results of those initial experiments. github.com/lmanchu?page=2…

Small step for a finger on "post tweet" button. Big step for millions of future AI agents doing useful work for us.
