Our story
Born from a real estate professional's observation.
Homeowners were already receiving notes from interested buyers. The problem was keeping track of them.
Working as a real estate agent, I kept seeing the same pattern: homeowners who were open to selling would mention they'd received notes from interested buyers — sometimes weeks or months earlier.
But when I asked to see those notes? They were gone. Lost in a drawer. A phone number scrawled on a crumpled piece of paper, too faded to read. Contact details that had long since become unreadable.
These weren't just lost letters. They were lost conversations. Lost deals. A buyer who was genuinely interested, a homeowner who might have been ready — and nothing left to connect them.
That's the moment DoorLetter was born. Not just a way for buyers to send notes, but a permanent inbox where every note is safely stored and easy to respond to — whether you're ready to sell tomorrow or in five years.
"The best deals I ever saw were made before the listing was live. A buyer had simply sent a note — and the homeowner remembered."

The founder
Jiri
Founder & Real Estate Agent, Maastricht
Jiri has worked as a real estate agent for years and sees daily how the housing market works. The observation that led to DoorLetter was simple but powerful: the notes already existed, the structure to keep track of them didn't.
DoorLetter was built to connect buyers and sellers in a fair, human way — whenever they're both ready.
Our mission
Make off-market home buying accessible to everyone.
The housing market is competitive, opaque, and often unfair to buyers without deep networks. Our mission is to level that playing field — one personal note at a time. We believe the best way to find a home is still through a genuine human connection.
Personal over transactional
Every note should feel crafted and genuine. We built AI assistance that helps you sound like yourself — not a form letter.
Respectful by design
Homeowners receive a single, thoughtful note — not a barrage of calls. We believe buyers and sellers both deserve dignity.
Transparent pricing
No hidden fees or surprises. You pay for notes when you need them, and homeowners only pay when they're ready to act.
Built on real experience
DoorLetter was built by people who understand both sides of a property transaction. That context shapes every decision we make.
