Building software used to be about assembling pieces. Today, it's about partnership with intelligence.
When we set out to build Letterhead, we noticed a problem: creators and businesses were drowning in fragmented tools. You had one platform to send newsletters, another to process payments, a third to manage your calendar, and a separate tab open for your AI assistant.
We decided to change that. We didn't just bolt AI onto legacy software; we built an AI-native ecosystem from the ground up.
Letterhead isn't just a place to draft brilliant, AI-assisted content. It’s an intelligent engine where your writing seamlessly connects to your subscription billing, where your audience data informs your next post, and where your scheduling happens automatically. It acts as an extension of your own mind—automating the drudgery of business operations and surfacing insights that inspire your best work.
Our pledge to you is simple: total ownership of your audience, zero platform lock-in, and the absolute best tools on the market working together flawlessly.
We invite you to stop just managing work, and start orchestrating success.
