Our story
Why we built LetterLeaf
Email runs every business on earth — yet it hasn’t evolved in 20 years.
It’s still where opportunities are won, deals are lost, and decisions get buried.
Letterleaf exists to change that.
We’re building the intelligence layer for business communication — starting with email.
Our mission is simple: ensure no opportunity is ever lost because someone missed a message.
Letterleaf reads, prioritizes, routes, and acts — turning your inbox into an intelligent teammate that keeps work moving forward.

The friction that sparked LetterLeaf
After nearly a decade in SaaS, I’ve worked across every part of the business — product, sales, support, and customer success.
I helped scale a product from zero to over 20,000 users, and somewhere along the way, email became my biggest source of friction.
Not because I was bad at it — but because everything important flowed through it.
Bug reports meant for support. Feature requests that needed triage. Sales intros. Renewals. Partnerships. Internal decisions.
All of it, in one endless stream.
Even on good days, things slipped.
Important threads got buried. People waited too long. Opportunities were lost.
And it wasn’t just me. I saw it everywhere — product managers, sales leads, support reps — all trying to keep up with a system that was never built for how teams actually work today.
That’s when I started building Letterleaf.
Not another inbox tool — but a smarter way to communicate — one that understands context, acts with intent, and makes sure the right things always happen.
