How Slashy Hit #1 on Product Hunt & Scaled to Thousands of Users Overnight

In this video, we sit down with Pranjali and Harsha — co-founders of Slashy (YC25) — to unpack how they shipped their AI email assistant without wasting months on long Google review cycles. Right before launch, Slashy hit a wall: ❌ No CASA approval ❌ No OAuth certification ❌ Gmail access limited to 100 pilot users ❌ A product they couldn’t properly ship without integrations Instead of waiting weeks (or months) for Google to approve access, they needed an infra layer that worked on day one. That solution was Composio. Get the inside story on how Slashy: ✅ Used Composio to safely connect Gmail with no manual approvals ✅ Removed their 100-user bottleneck instantly ✅ Shipped an AI inbox assistant built on agentic actions ✅ Focused fully on product, UX, and customer experience while Composio handled integrations ✅ Unblocked launch timelines without compromising security or trust If you’re building an AI or agentic SaaS product and auth + integrations are slowing you down, Composio is the cheat code.
