Superhuman vs Sistava
Superhuman is the fastest email client, built on keyboard shortcuts, aggressive performance work and AI drafting, triage and follow-up reminders. Founded in 2015, it raised over $114M at an $825M valuation before Grammarly acquired it in July 2025; by October 2025 the parent company had rebranded as Superhuman and launched a suite spanning writing, workspace, mail and a proactive assistant. Sistava does not compete on inbox speed. It competes on whether a human needs to be in the inbox at all for a given piece of work.
