It doesn't matter what you are trying to achieve, you will struggle to make significant progress as long as you are afraid of ignoring the rest of the world temporarily.
Everyone is constantly trying to get your attention, and if you don't tightly guard your time and energy, you will just spend your whole life doing everything superficially and achieving nothing substantially.
You might actually even end up with some money and status for being a compliant worker, but you will also feel empty inside, because you will always know that you were merely walking on someone else's path, a joyless and not nearly as meaningful trip.
A successful journey begins with the courage to make your own choices, not look back, and keep moving forward despite the consequences of the inevitable mistakes you will have to deal with along the way.

Excited to announce that @trydatabuddy is part of the YC F26 batch!
Collecting data is easy, understanding it isn’t.
That's why we're building Databuddy, the most comprehensive intelligence platform that combines all of your analytics and context into informed business insights and investigates your product issues as they happen in real-time
If you're tired of spending hours in your posthog dashboards trying to make sense of your data, this is for you

Paper Mono!
sooo excited to finally release our free and beautiful mono font
it works incredibly well for design, coding, and even prose, and it’s packed with features: variable font weight, coding ligatures, duospacing (!) for long-form text, and more.
sound on:

Google just led a $20m round into a complete rip-off of my startup, Fastlane.
(skip to 55 seconds to skip context)
This isn’t something I’d normally talk about, but a line has been crossed. This disgusting and egregious behavior honestly makes me sick.
Fortunately, there is nothing anyone could do to stop us from winning. Especially not some unimaginative NPC’s. Good luck fellas.
Today we’re introducing Relay
We raised $20M from Google, Point72 & the founder of Reddit to build it.
1) Drop your website
2) Relay will create your content
3) Automatically distributes to our network of 50,000 U.S. creators
4) Drive millions of views and insights for your brand
Comment your website URL below and we’ll build your brand’s content library for free 👇
Readers added context they thought people might want to know
The post claims Relay raised $20M from Google, Point72 & Reddit's founder with a 50k US creator network, but the site describes a small-scale TikTok content tool with no such details or scale and no independent sources confirm the claims.

The post claims Google led a $20M round into a real "Relay" rip-off of Fastlane, but no such funding or scaled competitor exists; it amplifies unverified hype for a basic tool contradicted by its site and community notes.

It is unethical per se to even interview at a competitor while attending Board meetings and Board dinners.
Filip Sanda retweeted
what the actual fuck, Vinod
You are a struggling second tier competitor that is more unethical and lying just because you have no decency or sense of proper behavior and shows your desperation. Straight out lying about if Chris being fired I thought would be below even you.

For the last month @miaugladiator1 and I have been obsessing over building the best platforms for companies to rank in AI Search
Today we are finally launching Notra GEO, the first step of our plan to achieve this!

We got our MCP approved for ChatGPT and Claude, and we’ve also submitted it to Cursor / Grok Bot directory, but we haven’t heard back yet.
Is there anyone who could help us with this? cc: @leerob

tips when dealing with VCs:
- "maybe" is a no
- "yes, i will co-lead if you find a lead" is a no
- "yes, if you can convince this other fund" is a no
- "yes, but i can't wire right now" is a no (HUGE RED FLAG)
- "yes, i just need to see some more traction" is a no
they're keeping optionality. they don't believe in you, but they still wanna join the round if it turns out to be hot.
there's only one right answer to all of these:
"sorry, i cannot reserve you a spot. if you want in, you will have to tell me now."

Gave @PrimeIntellect's new self-improving agent an E2B sandbox and told it to play @factoriogame.
Factorio is a long-horizon test of world models: the agent has to learn a new system, predict the effects of its actions, and adapt when its assumptions are wrong.
That requires a persistent sandbox like E2B that can keep the game running and retain its state while the agent works.
Spin up a lot of sandboxes and benchmark prime agent or run your own evals with E2B.
Try it yourself: e2b sbx create prime

2026 is the year of agents building other agents.
We shipped the agent builder to CRM today.
You can tell it to do things like 'send me an overview of all deals every Friday on Slack' and it'll code another agent to do just that.
