I build startups because my mom says I'm special. Founder of Glitter AI @glitterai and Simpo (acquired in 2021).

[Amitay Gilboa @GilboaAmitay]

We got an 8-figure acquisition offer 2 days after launch.

We said no, because the problem we're solving is worth way more than that.

It’s 2026, but teams are only getting lonelier, and context is still the problem.

The issue isn’t intelligence. Your team has plenty of that.

It’s shared memory and context, the thing that makes 10 A-players feel like 1.

That’s what we’ve solved with @playdotfast, while making work more fun.

We're killing traditional SaaS, and believe you me, we're leaving no holds barred.

first step in the @postmarkapp setup: setting up a "stream" for global marketing messages and another for transactional emails.
next up, i plan on creating an interface that can basically take in a simple mermaid diagram and turn it into a marketing campaign <3

[Yuval Karmi @yuvalkarmi]

finally gating some features for Glitter AI. Guides now *do* limit to 10 total for free accounts (I didn't enforce the limit until now)

[Yuval Karmi @yuvalkarmi]

today's task for Glitter AI as a solo founder: rip out Intercom's email marketing and replace it with my own custom implementation with @postmarkapp. Wish me luck!

[Yuval Karmi @yuvalkarmi]

So far I've posted mostly on LinkedIn - let's see how it goes in the twitterverse... ugh... X

[Yuval Karmi @yuvalkarmi]

I'm building Glitter AI in public.

Marketing as an engineer in 3 simple steps:
1️⃣ Open Claude Code in your codebase
2️⃣ Type /agents => New Agent
3️⃣ "You're an expert SEO writer. Scan codebase to figure out what it does, then using this keyword list export from [SEMRush|ahrefs], write a full content plan

[Yuval Karmi @yuvalkarmi]

Marketing is now an engineering activity. This is crazy.

48 hours ago, I generated 76 high quality posts using AI agents that research, write, fact-check, and optimize for SEO- autonomously.

0 marketers. 1 engineer (me).

If you need advice, here's who you talk to:

➡️ Other founders / CEO circles
➡️Coaches
➡️Therapists

❌ Not VCs.

VCs are not your friends.

They are capital allocators.

[Yuval Karmi @yuvalkarmi]

VCs are not your friends.

They are capital allocators.

Even "founder-friendly" VCs have to prioritize their fund over your wellbeing.

Friendliness ≠ Friendship

[Yuval Karmi @yuvalkarmi]

When shit hits the fan, most VCs go into firefighting mode and try to recover capital.

It's their job.

Some carry it out with more grace and humanity than others.

@sama @OpenAI well, you probably saved this person's life.

The gist: ChatGPT diagnosed an early form of an aggressive cancer after doctors failed to explain her symptoms for > 1 year.

[Yuval Karmi @yuvalkarmi]

@Shai_Alon That is super interesting. How can I use seeding for Veo3?

[Yuval Karmi @yuvalkarmi]

@fawiatrowski This is VERY well done marketing through storytelling. Genuinely inspiring in the literal sense of the word (meaning I intend to take this idea and run with it, hope that’s okay)

[Yuval Karmi @yuvalkarmi]

@orslimy @glitterai מרגש! נתראה מחר :)

[Or Azulay @orslimy]

היי כולם! מחר אארח בספייס את @yuvalkarmi, שמכר את החברה הראשונה שלו ל-Walkme, והיום עובד על @glitterai - מוצר שעוזר לאנשים לייצר מדריכים ויזואליים פשוטים מכל תהליך מורכב ומבאס במחשב, ונשוחח על המסע שלו ועל בניית מוצרים מגניבים בבוטסטראפ. בואו :)

@exceldictionary Love this! Btw if you like Scribe, I think you'll love Glitter AI. It's a competing tool I created that works faster: you just SPEAK to write your guide. Here's a 1:1 comparison:
