XMTP
@xmtp
Come build the most secure and private messaging network in the world—owned by the people who build it and use it.
Introducing the XMTP Switchboard - a global network of offices for our digital community and team to come together IRL.
We are launching this week at 20+ offices in 12 cities around the world:
🇺🇸 SF, NYC, Austin, Nashville, Savannah
🇮🇹 Rome, Venice
🇬🇧 London
🇯🇵 Tokyo, Osaka
🇭🇺 Budapest
🇸🇬 Singapore
...
Hi Casters. Our portfolio company @xmtp is taking an approach to office space that I really like. Instead of being fully remote or entirely in one office they are opening a network of workspaces for themselves and their ecosystem of builders around the world. They tweeted about it today https://x.com/i/status/201837387

The attention economy just flipped.
Most platforms rent your attention.
They charge you to message, gate access, and keep the upside.
Introducing Zora DMs (secured by XMTP):
→ You invest in a creator
→ You unlock direct DMs
→ You both share in the upside
