@zjearbear Best launch video ever

[Yahia Bakour @mynameisyahia]

We're seeing an influx of organic reddit mentions.

Seems what we're doing is certainly working.

Congoo @KaraLabsAI, for the amazing launch!!!

Kara is building the Diamond Age.

[Kara (YC S26) @KaraLabsAI]

Today we are excited to launch Kara, backed by @ycombinator (S26).

We grow ultra-high-purity diamond wafers for AI chips, spacecraft, RF systems, lasers, and quantum hardware.

Diamond can move heat 5× faster than copper, helping the world’s most power-dense systems run harder and cooler.

But thermal management is only the beginning.

Silicon transformed computing when we learned to manufacture it with extreme purity and control. Kara is doing the same with diamond.

Today, our ultra-high-purity diamond pulls heat away from silicon chips. Tomorrow, Kara’s control over purity and defects unlocks diamond as the ultimate semiconductor.

Kara is building the diamond age.

@michaelwangelo Congratulations 🎉 on the launch!

Startups valued in the billions now do rounds in the hundreds of millions on safes. The unexpected versatility of this instrument shows what a good job Carolynn Levy did when she designed it.

[Prashant @prashant8124]

The essays that shaped how I think were written by someone I assumed I would never meet. Today he spent an afternoon helping two founders (@jadenswang ) get better. Thank you @paulg and @jesslivingston for having us! This was the most memorable afternoon of my career

There is more AI compute in the world than ever and it is still absurdly hard to actually get any of it. OpenRelay makes every chip across every cloud look like one endpoint. 100B tokens a week already running through it. If you need compute; they've got it.

[Prashant @prashant8124]

We have been hard at work!

[OpenRelayInc @OpenRelayInc]

Launching @openrelay: One Endpoint to Rule Them All

- 100B tokens/week across 22 locations on 4 continents
- 8 accelerator SKUs: NVIDIA, TPU, Trainium, AMD
- Up to 20% cheaper than renting the hardware yourself

Every chip on earth. None of them your problem.

Run inference on the world’s compute

Every startup should have a daily markdown file called "what_the_market_is_telling_us.md"

It updates every morning from the places where customer truth already lives:

1. Stripe for who pays, upgrades, downgrades, and churns
2. PostHog for what people actually do in the product
3. Intercom or Plain for support tickets/complaints
4. Granola or Gmeet transcriptions for sales calls/ customer interviews
5. HubSpot or Salesforce for CRM notes/lost deal reasons
6. Linear, Jira, or GitHub Issues for bugs and feature requests etc
7. Ideabrowser MCP for outside market signal: startup ideas, trend reports, social/search demand, AI research reports, and builder prompts that show what people are starting to want before it shows up in your own customer data.

Basically, the file should notice what changed in the business this week and not just be this summary of here’s what happened (which I think a lot of people have their agents do).

Why this is valuable:

1. Maybe new buyers are using different words than they were a month ago.

2. Maybe trial users are getting stuck in the same place.

3. Maybe upgraded customers all touched one feature right before they paid.

4. Maybe churned customers keep mentioning setup confusion.

5. Maybe sales calls are suddenly losing to a competitor you used to beat.

6. Maybe support tickets are revealing a workflow your product accidentally became responsible for.

You get the point.

The fastest way to PMF is understanding customers better than anyone else, and the highest signal customer insight is usually a change in behavior.

So I’d have the agent update the file every morning with the pattern it found, the receipts behind it, and the product or GTM decision it might affect.

For example:

“3 customers who churned this week all mentioned setup confusion, and 2 of them never invited a teammate.

This looks more like an activation problem than a pricing problem, so I’d look at team invite and onboarding before building another analytics feature.”

A little helpful tip for all those out there looking to get more from their LLMs.

@virattt @findatasets This is the way to go!!

[Yahia Bakour @mynameisyahia]

Anecdotal pattern I’ve noticed:

The more successful someone is, the kinder and more earnest they tend to be

The people who are not doing too hot are often cocky & the most performative

@realAkashAnand @ycombinator Who won the pot @realAkashAnand after I left?

[Prashant @prashant8124]

@mynameisyahia Plus one all the points @mynameisyahia said; going through S26 I can say It’s remarkably normal and secret sauce really is hardwork and make something people want at the end of the day
