Silmaril (@Silmarildev) is the first self-healing prompt injection defense. It catches 2x more attacks 10x faster than leading defenses, and retrains continuously to protect your full AI stack, including agents like Claude Code and OpenClaw. Congrats on the launch, @aumup001 and @EduardoVel36291! ycombinator.com/launches/Pvl…

“Aha, that’s so crazy that happened haha we live in a simulation.” No, you moron. God is real. This is how He taps the glass. Synchronicity. Small winks. Precise hits that land too clean to be random, the names that keep repeating, the doors that open on the day you were ready to quit You hide behind ‘simulation’ so you never have to admit Someone is actually calling you to do something with your life

"...there is not a fixed amount of wealth in the world. You can make more wealth." Paul Graham on the Pie Fallacy:

When you build a facility that employs thousands, you don’t only create jobs. As our CEO @LaFrogman put it: You raise wages, strengthen local businesses, pay taxes that support services, and create downstream opportunities that impact tens of thousands more. Last week, @ti_morse brought together five frontier founders leading with that vision, @sdamico, @jasonjoyride, @willob, Michael LaFramboise, and @laurence1allen each building to shift the paradigm of what American industry can be. America’s strength comes from building things. It’s time to Reindustrialize America.

Christian is working on some really cool stuff. Keep an eye out 👀

If you're applying to YC, make your application uncomfortably short. Partners are reading thousands of apps. They are skimming through all of them. Make their lives easier. Simple and short. Trust me.

Some of you have never hit this mode on an NYC Saturday night and it shows

CopyCat is the AI RPA. Companies, from enterprises to startups, are saving thousands of hours building browser agents to automate gov sites, legacy portals, and dashboards, where APIs can’t. Congrats on the launch, @GrahamSabin, @zyadelgoharyx & @a8hi_b! ycombinator.com/launches/O1l…

We spent about 3 months building out browser agents inside of enterprises. The results were pretty astounding. Some saving 1000 hours/month. Today, we decided to make our internal tool for building RPA, widely available. Go automate something your competition can't.

Excited to announce our $4.2M seed round led by @Moonfire_VC , Burst Capital & @ycombinator and the release of our AI engineering optimization platform. Weave is building advanced engineering analytics for the AI era. Since launching in January, we've been helping hundreds of the fastest-growing teams optimize their use of AI code editors, agents & reviewers. Here's the problem we're solving: Engineering teams are throwing money at AI tools with no way to measure how effective they are or how to improve. The early results are incredible - teams using our platform are seeing 16% higher output with proper AI implementation. Huge thank you to our early partners & investors! This is just the beginning, so back to shipping & selling :)

Learnings: - Pricing too low for a pilot/trial/etc. will give a hard anchor to get over - Utah has a surprising number of good startups - Mormons can't consume coffee, but they can consume caffeine (and a lot of it)

I stuck it to the man today. Amazon 1-day shipping was an extra $2.99. Hell no, I'm not paying. Instead I added $30 worth of shit I don't need to my cart and got the 1-day shipping for free.

If you are thinking about building an agent don’t forget to ask @dexhorthy for permission. @humanlayer_dev

Somehow Zapier may be one of the most un-intuitive products I have ever used

"Nine times out of ten, sitting around strategizing is just a form of procrastination." -pg

I asked Garry how he knows a special founder when he sees one, and he gave a great articulation that I had never heard but immediately resonated. Listening to it again now, it's basically the trait that allows people to "make something people want".
