Slashy Launches "Cursor for Email" to Help Knowledge Workers Fly Through Their Inboxes

Email remains the universal input tray of knowledge work, and despite two decades of startup promises, most professionals still spend hours a day on it. Slashy, a Y Combinator Summer 2025 company, is taking another run at the category with an AI email assistant it describes as ‘Cursor for Email’ – an agent designed to help users fly through their inbox rather than triage it line by line.

The analogy to Cursor, the AI-first code editor, is deliberate. Rather than bolting a chatbot onto an email client, Slashy’s vision is for the AI to sit inside the composition and triage flow itself, surfacing the right action at the right moment: drafting a reply in the user’s voice, summarizing a thread that sprawled overnight, unsubscribing from noise, pulling the one sentence in a long message that actually requires a response. The goal is to collapse the hours most knowledge workers spend in email into minutes without sacrificing the nuance of professional correspondence.

Slashy’s founding team is unusual even by YC standards. Co-founder Pranjali Awasthi is 18 years old and previously ran an HF0-backed AI copilot for researchers while in high school – arguably the only teenager in the batch to have closed a funding round twice. She is joined by co-founders Harsha Gaddipati and Dhruv Roongta. Roongta previously studied CS at Georgia Tech and interned at Groq, Pulse (YC S24), and Greptile (YC W24), and has placed in multiple CalHacks and HackMIT competitions. The team is pitching itself as the archetype of the new YC founder – young, technically aggressive, and unafraid to take on entrenched incumbents.

The market is enormous and stubborn. Google and Microsoft have spent decades trying to modernize email, and newer entrants like Superhuman have built profitable businesses by serving the small slice of users willing to pay for speed. Slashy’s wager is that the arrival of capable, affordable language models changes the math: a fully agentic email experience that used to require an entire custom stack can now be built by a small team that moves quickly and ships fast.
