Why We Built LetterLeaf
Because teams shouldn’t lose opportunities just because someone missed an email. LetterLeaf was created to help you stay focused, act fast, and never let the right message slip through the cracks. It puts human-first AI into the heart of your communication workflow.
The Friction That Sparked LetterLeaf
After almost a decade in SaaS, you get used to wearing a lot of hats.
Product. Sales. Support. Customer success. I’ve worked across all of it. I helped scale a product from zero to 20,000+ users, and somewhere along the way, email became my biggest source of friction.
Not because I lived in my inbox all day, but because everything important came through it.
Bug reports meant for support. Feature requests that needed triaging. Sales intros. Renewals. Partner threads. Internal decisions. All in one stream.
Even on a good day, things slipped through the cracks.
Important messages got buried. People waited too long. I’d follow up days later and feel terrible.
And I started seeing it everywhere. Product managers. Sales leads. Support reps. Everyone was trying to keep up, but inboxes weren’t built for how modern teams actually work.
So I started building LetterLeaf.
