Your time is too
expensive for email.
Bért is an AI chief of staff that runs your inbox and calendar like a private office—reading, sorting, and drafting so you can think instead of administrate.
Built for founders, investors, executives, and family offices.
Order from chaos.
As you move through your day, Bért quietly organizes the noise into clarity.
The Briefing
Wake up to one short summary: what changed, who needs you, and three emails that actually matter.
The Gatekeeper
Bért quietly files newsletters, drafts replies in your voice, and protects focus blocks.
The Clean Slate
End the day with a prioritized inbox and a short list of promises kept. No scrolling. No guilt.
Not a slideshow.
Your actual inbox,
redesigned.
This is the smallest version of Berthier you'll ever see: an executive inbox with context, coaching, and taste. One canvas for what matters: who needs you, what's blocking, and what Bért already took care of.
Curated Solitude
Filters noise. Only the urgent and meaningful get through.
Correspondence with Soul
Drafts that sound like you on your best day.
Built for people who can't afford a leak.
Bank-grade protection
End-to-end encryption, hardware-backed key management. Credentials are never stored in plain text.
Isolated execution
Every action runs in a private sandbox, isolated from other clients. If something goes wrong, it stays contained.
Your data stays yours
We don't sell it. We don't train public models on it. We don't share it. Full stop.
“It's rare to find software that feels like an extension of your mind, rather than a tax on it.”
Elena • Founder, Series BYour inbox becomes a private office overlooking a quiet landscape,
not a trading floor.

Berthier is not a mass-market product. We work with a small number of founders, investors, and family offices where an hour of time saved is material.
