I turned down my DynamoDB internship to join @ycombinator F26.
we're building simulations at @Simulithic to simulate user behaviour at scale.
i'm just a regular person who kept building things i thought were cool! if i can do it, so can you.
and if you’re choosing between a big-tech and building something, my dms are always open.
onward.
I'm not even kidding, this is the best product ever
Shipping code shouldn’t mean hours of manual testing.
@Simulithic (YC F26) sends AI agents through your app like real users, across browsers, devices, and account types. It tells you what broke without you writing a single test script.
The teams that ship fastest will be the ones that can verify as fast as they build.
Get started today: simulithic.com

we (@simulithic) are launching on @ycombinator tomorrow!
it honestly still feels so surreal.
because to be honest, i'm a pretty normal person.
but in the words of one of my goats (@mynameisyahia):
i just kept going, worked harder than most, and kept learning from people ahead of me.
see you all tomorrow 🫡🚀

I reverse engineered Pocket and made it 10X better.
Right now: the app is full of ads, the microphone is low quality, it constantly misspells peoples names, and has no agentic features.
I changed that.

We raised $9M to give your agents the internet.
Led by @generalcatalyst, with @orangecollectv and Robinhood Ventures.
Search, scrape, crawl, monitor with one API trusted by 800+ customers.
We’re making it ridiculously easy to build with web data.

Today we're launching @VeezaAI (YC F26) - an AI tourist visa agent for people with weak passports.
Yes, you read that right. Weak passports.
If you have a US or EU passport, you book a flight and go. For the rest of the world, every trip starts with forms, bank statements, and fighting for an appointment.
We've suffered through this for 30 years. Those days are coming to an end.
Pick your destination. Veeza AI does the paperwork and books the appointment.
start at: veeza.ai

Small businesses don't need a website builder. They need someone to do their marketing. They need Theo.
@theo_site (YC F26) is the AI agent that builds - or rebuilds - your site, then works 24/7 to get you found on Google and in AI search.
You run the business. Theo does the marketing. Free audit: theo.site
we'll send you $50 if we can't find any bugs!
since we've gone live with several companies ranging from YC to series A, our biggest ask was to try our product first.
so the first full audit is free!
steps to claim potentially a free dinner:
- book a demo with @Simulithic using link below
- w ithin 48 hours, our AI users test your product on every device, browser and account type
- if we can't find a single bug, dinner's on us: a $50 DoorDash/Uber Eats credit, or we'll take you out!
requirements:
- must book call with work email :)
if you're sick and tired of maintaining flaky E2E tests or clicking through the same screen 10230189 times, let's chat!
