Simulithic (YC F26)

AI users that test your app on every device and browser.

[Satyam @KlausCodes]

If you're not using your own product, you're NGMI

A lot of small teams, ship directly to prod.

We personally just use @Simulithic to verify it.

No need to wait for 30mins to run the tests that still don't catch all the issues.

Just verify your changes using @Simulithic.

[Satyam @KlausCodes]

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.

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 🫡🚀

[Ryan Ning @itsnotryan]

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!

[Satyam @KlausCodes]

If we don’t find bugs in your platform, I’ll buy you a dinner.

- It has to be a startup/company
- We will do a full audit using @Simulithic
- If we don’t find any bugs in any simulated environment, we will buy you a $50 DoorDash gift card

Introducing Real-World Verification.

@Simulithic can now run 1,000s of VMs in parallel, simulating your users’ behavior across different devices and environments.

Catch the bugs your coding agent missed before they cost you customers.

I cancelled my Claude Max sub so I can jump on @Simulithic -- I can't live without this tool.

Making something people want at @ycombinator F26

Building simulations at @Simulithic to model user behaviour at scale.

[Ryan Ning @itsnotryan]

in NYC for a couple of days with @KlausCodes! would love to meet and talk tech 😼

[Satyam @KlausCodes]

We are back in NYC for few days

If you work at a company or run one in NYC then would love to stop by (with some donuts), and learn how you manage tests (there’s a way to fix that 👀)

[Satyam @KlausCodes]

At @Simulithic we simulate user-behavior

While building it we realized we were monitoring production every single time I push a change

So now my agents that actually behave like our users, monitor our production to make sure its never broken

Making it available for early users

If you ship fast, lets schedule a call: https://t.co/UD392ckJFH
