2X YC founder. Working on something new.

You don't have to trade quality for speed anymore. The future has arrived.

[dex @dexhorthy]

At HumanLayer, we’re on a mission to solve the AI slop code problem.

In 2025 we open-sourced our Research, Plan, Implement framework, now deployed inside fortune 500s like Block and Uber - places where shipping slop is just not an option

And that was just the beginning.

Today, we’re opening access to HumanLayer - an Agentic IDE, collaboration platform, and building blocks for your software factory.

HumanLayer enables engineers solving hard problems in complex codebases to:

> move 2-3x faster across the entire SDLC (not just coding)

> maintain rigorous standards for system architecture and program design

Hundreds of engineers at companies of all sizes are already using HumanLayer to ship fast without sacrificing quality.

I'm excited to invite you to try humanlayer today at https://t.co/cQ648EkrnG, and I'm even more excited to see what you build.

@0xblacklight and I are deeply grateful to our team, our customers who give us so much incredible energy and feedback, our investors who have always been in our corner, and our friends and family who have supported us along this crazy journey

if you're a staff or principal engineer trying to make AI coding work at scale for your team, we'd love to hear from you

as @swyx likes to say - let's make this the year of no more slop

[Matt Lenhard @MattLenhard]

Ploy has led to a fundamental shift in how I think about my website and marketing. The "ploys" are actionable, useful, and gave me ideas I would never have thought of before. Highly recommend to anyone building.

[brryant @bryantchou]

AI is making marketers lazy.

So we made the website do the work instead. Today, we're launching @ployai: the all-in-one marketing platform that turns your website into your hardest working employee.

And we're coming out of stealth today with a $27M seed led by @ycombinator and @firstround.

I spent 12 years at Webflow as the founding CTO where I built the product, but also started our marketing and sales teams that drove our fastest periods of growth. That experience made one thing obvious: the website is the center of your business. And it's only more important in the age of AI.

Foundation model apps can generate assets.
Point solutions can optimize pieces of the funnel.

But nothing runs the whole growth system: your site, brand, CMS, CRM, campaigns, analytics, SEO, AEO, and customer data all working together.

Until now.

Teams at @hex_tech and @clay_run, and growth agencies like Tonik and TNT Growth, are already powering sites on Ploy. Hex is generating on-brand ABM pages at scale, Clay is using its data to power a programmatic SEO engine, and TNT Growth is spinning up a landing page for each of their clients’ ads.

Wake up every morning with a report from Ploy - with what it did, and what it wants to do next.
Approve it. Ship it.
Or be lazy and just watch it cook.

Happy to see Instant offering a backend with a sync engine.

More apps should work this way and now combined with AI this could finally be the new default for web apps. No more slow web apps with skeletons and rendering jank

[Matt Lenhard @MattLenhard]

@stopachka Instant is the future! Congrats on 1.0.

[Matt Lenhard @MattLenhard]

@spencermateega Congrats! Excited to be along for the ride and to see whats next.

[Matt Lenhard @MattLenhard]

@shcallaway @sazabi @pgillin @SiliconANGLE Love it man. Instrumentation and monitor creation is such monotonous work. Can't wait for the day where its no longer necessary. Everything should be automated.

[Matt Lenhard @MattLenhard]

@morganlinton I look at that as a client-side problem. Can be solved via progressive discovery, it's just that most clients decide to load every tool into the context window when they shouldn't be

[Matt Lenhard @MattLenhard]

@bernhardsson CI has become the bottleneck for nearly everything for me recently. Having an agent finish a feature in 2 minutes, then waiting 20 minutes for CI to finish, kills productivity.

[Matt Lenhard @MattLenhard]

@diptanu Yeah I think we'll see sandboxes move to be more stateful over time. The issue is going to be maintaining that state while also keeping cold start latency low.

[Matt Lenhard @MattLenhard]

@morganlinton Yeah, agreed still a lot of ways to do things wrong with MCP. No silver bullet, but I do like that it has at least some standards if you do decide to follow the spec.

[Matt Lenhard @MattLenhard]

@Keshavatearth @andrewqu @strehldev I think it just the importance of the underlying harness.

[Instant @instant_db]

Hey hey everyone! Wanted to let you know we just released Storage out of beta!

This means all apps can upload images, documents, etc. with Instant.

Free apps can store up to 1GB and paid ups can store up to 10GB and then $0.125/GB after.

[Matt Lenhard @MattLenhard]

@gaganghotra_ With the compute cost required for generative AI I'm guessing this was an inevitability

[Matt Lenhard @MattLenhard]

@glenngabe can be especially problematic when a staging subdomain is inadvertently indexed.

[Matt Lenhard @MattLenhard]

@ViperChill Honestly surprised it’s not even higher. The last report / roundup you put out was one of if not the most interesting things I’ve read all year. Easy to see all the hard work that went into it.

[Matt Lenhard @MattLenhard]

@NickLeRoy It really is a flow killer and just ends up driving me back to chatGPT.

[Matt Lenhard @MattLenhard]

@NicheDown Pretty surprising that Google still struggles with hallucinations at such a fundamental level, while sites like perplexity seem to have least have them somewhat under control

[Matt Lenhard @MattLenhard]

@dejanseo The problem is that Google has so competently muddied the waters over the years that people don't know what to believe even when the facts are right in front of them.

[Matt Lenhard @MattLenhard]

@glenngabe Certainly a better experience than what you get with Google natively.

I would also be worried if I was a comparison shopping affiliate site reliant on traffic from organic.
