SUPERHUMAN MAIL πŸ‘‰

We exist so that professionals end each day feeling happier, more productive, and closer to achieving their potential.

Our customers get through their inboxes twice as fast; many see inbox zero for the first time in years.

Today we are…

πŸ“£ We've joined forces with Grammarly to build the AI-native productivity suite of the future, with Superhuman as the central communication layer. This partnership accelerates our mission to help professionals achieve their potential β€” now at even greater scale.

Come shape the future of email, communication, and productivity!

BUILD LOVE πŸ’œ

At Superhuman, we deeply understand how to build products that people love. We incorporate fun and play; we infuse magic and joy; we make experiences that amaze and delight.

It all starts with the right team β€” a team that deeply cares about values, customers, and each other.

CREATE MASSIVE IMPACT πŸš€

We're not solving a small problem, and we're not addressing a small market. We're going after email; the one activity that consumes more of our work day than any other.

Our ambition doesn't stop there. Next: calendars, notes, contacts, and team communication. We are building the productivity platform of the future.

DO THE BEST WORK OF YOUR LIFE 🌟

We have created the frameworks for how to build product market fit and redefined the narrative of how to onboard customers successfully. We have shown the world it’s possible to build a premium productivity brand. Our investors included Andreessen Horowitz, First Round Capital, IVP, Tiger Global Management, Sam Altman, and the founders of Gmail, Dropbox, Reddit, Discord, Stripe, GitHub, AngelList, and Intercom.

This time, we’re swinging beyond the fences and fundamentally rethinking how individuals and teams should collaborate. We are building a household brand and a worldwide organization. We are here to do the best work of our lives, and we hope you are too.
