Y Combinator backs VibeGrade

VibeGrade Joins Y Combinator’s Spring 2025 Batch

We're excited to announce that VibeGrade (formerly GradeAssist) has been accepted into Y Combinator’s Spring 2025 (X25) batch.

Y Combinator is one of the world's most prestigious startup accelerators, known for backing companies like Airbnb, Stripe, Instacart, Clever, Coinbase, OpenAI, and DoorDash.

VibeGrade is the first AI grading assistant that works directly inside Google Classroom, Google Docs, and Canvas to help teachers grade essays 10x faster, in their own style. No uploads, no new tools—just one click for detailed, rubric-based feedback.

So far, we've helped teachers save over 500 school days across 12,000 essays.

Joining YC gives us the opportunity to scale our mission: helping teachers spend less time grading and more time teaching.

If you know an educator who could use a break from grading, send them to vibegrade.com.
