The YC application is one of the most important forms a startup can fill out. It is also one of the most tedious: dozens of fields, multi-page navigation, character limits, and nuanced questions that require real thought. We gave Coasty the challenge.
What We Provided
We gave Coasty a document with our company information: founding story, team bios, traction numbers, and product description. The instruction was simple: fill out the YC S26 application using this information.
How It Performed
- ●Navigated to the YC application page and started filling fields
- ●Handled text inputs, dropdowns, radio buttons, and text areas
- ●Respected character limits by condensing content appropriately
- ●Navigated between multiple pages without losing context
- ●Filled 30+ fields in under 15 minutes
- ●The application was coherent and well-written
Form filling is one of the most natural use cases for computer use agents. The YC application is a particularly demanding test, and Coasty handled it well.
