@taro_f @try_channel3 Thrilled to be working with you!

I'm excited to announce my investment into Channel3 (@try_channel3) in YC S25. Channel3 is building the universal product database that makes commerce accessible to everyone. Today, when you shop on Google, Amazon, or ChatGPT, you’re tapping into their private product catalogs. Channel3 is opening this up — creating a database of every product on the internet and giving developers access to structured data on pricing, availability, images, and specs. With Channel3, any website, app, or AI agent can integrate commerce seamlessly, earning commission on every sale without dealing with inventory, payments, or affiliate hassles. This makes it possible to power new experiences — from a kitchen assistant that recommends tools to a fitness app that suggests the right equipment — while driving new revenue streams for developers. Founded by Alexander Schiff (@schiffyalex) and George Lawrence (friends from Duke with prior experience at Palantir), Channel3 was born from Alex’s firsthand challenge of giving an AI teacher the ability to recommend products. The team saw a bigger opportunity: enabling AI agents and developers everywhere to add shopping capabilities natively. As AI models become more capable at recognizing and linking products across merchants, Channel3’s catalog will only grow stronger. The vision is simple but ambitious — to power the next generation of shopping experiences on the internet. Channel3 is backed by @ycombinator, @pioneer_fund, Paul Graham and other great investors (like myself 🥳).

Channel3 is live on Product Hunt!!! 🚀API is free for the next 4 days with code "PRODUCTHUNT" producthunt.com/products/chann…

@ycombinator @onkernel @juecd__ @rfgarcia congrats!!! we love Kernel!

Kernel (@onkernel) provides Crazy Fast Browser Infrastructure. Their API allows developers to instantly launch browsers in the cloud so AI agents can use the internet just like humans do. ycombinator.com/launches/O5f-k… Congrats on the launch, @juecd__ & @rfgarcia!

GPT-5 just built me a try-on app with @try_channel3 and @GlamAI_app Start building with 1000 free searches at trychannel3.com

not sure if this counts as exponential growth, decay, or a step function -- but a 95% decrease in one of our key pipelines is pretty good for 2 PRs

@igrigorik Cool! How does adding a non-Shopify product to cart work?

Commerce for Agents, batteries included [1].  📇 Catalog API is a massive unlock. Crawling is hard at scale and commerce crawling is a sysophean problem: international pricing and variants, availability, up to date pricing, .... good luck! Catalog gives realtime access to the entire Shopify ecosystem.  🛒 Universal cart solves cart tracking. Add items from multiple shops, including off Shopify, and it gives accurate totals, discounts, etc. All of the merchant logic like bundles, shipping estimates, etc. work out of the box.  💲Checkout is complex, we made it easy. Integrate native checkout experience with just a few lines of code thanks to Checkout Kit -- this is complexity compression of indescribable scale. All of the merchant logic works as expected, all the nightmares of PCI, privacy, and regulatory and compliance bazaar are handled by Shopify.  ✨ Bonus: a pre baked set of web components alongside every MCP response [2] that abstract all of the frontend pain and handle all of the complexity of commerce: variants, bundles, options, carousels, ..., carts.  In short, we erased a mountain of operational, backend (crawling, cart tracking), and frontend complexity (checkout, web components) so agents can focus on what they can do best: build the best shopping experiences for buyers.

When @try_channel3 finds a new brand, we use @ExaAILabs to grab its domain 🚀🚀🚀

🛍️ Your agent can now discover and recommend products 💸 You get paid when it drives sales Shout-out to @charlieholtz and @kamathematic for making MCP so easy Build an AI stylist/co-pilot/storefront with @try_channel3 docs.trychannel3.com/mcp-overview

@_glawrence classic!!!!

setting up self-hosted gemma 3n on AWS, thought I did something wrong, but I guess a gcc version mismatch is a rite of passage?

@_glawrence At 100M tokens/min on GCP Vertex AI. DQS is actually pretty good

"Now we're burning through thousands of dollars a minute. This is AWESOME!" - @_glawrence as he scales our AWS servers

@ShopifyDevs When will this be live?

Introducing: Shopify Catalog Your apps and AI agents can now search real-time product data across millions of Shopify stores.

@bnj @variantui would love to try

We raised $5.9M to build @variantui: code generation with taste, range, and room to explore Invites start rolling out today, reply for early access

@benhylak @raindrop_ai did it just look up my company from my email address and write a description for me during onboarding??? so slick

AI products fail constantly—in ways both hilarious and terrifying. Regular software throws exceptions. But AI products fail silently. Meet @raindrop_ai : the first Sentry-like monitoring platform for AI products.

@charlieholtz so cool. trying it but screen share doesn't seem to work on my M2 air. gave it permissions

You can now try it here! bartleby.ai

I put Gemini 2.0 inside a desktop app and gave it access to my screen, terminal, clipboard, and the internet:

@Dimillian whoa! how do you get this? is it automatic? not seeing it on my app

The fact that iOS automatically adjust the status bar color when you make a full screen app is simply amazing.

@ben_issen Would love to try this out! Been looking for exactly this. 😄

Created a prototype for an AI tool that generates Privacy Policy, Terms and conditions, copywriting, + 10 other use cases for web designers. I use it for myself and it's a huge time-gain. Hit me up to get early access.

@michael_vandi Would love to try!!

It’s done!! 🚀🚀🚀🚀 Introducing Addy - Your AI email assistant 🤖 Addy is powered by ChatGPT and can write emails for you 10x faster in your preferred style and tone. If you want early access, please retweet and comment below and I’ll send you an invite code!

@soffes Hey Sam, thanks so much for making this! It's been so great to use for all my online classes. It doesn't seem to work anymore – any advice on how to fix this or did Zoom change something to make it not work anymore? I appreciate your work!!!

Wrote a Safari extension to automatically open Zoom and close the tab. Still testing it. Will share once it's ready though!
