@hmason.bsky.social
Co-founder & CEO of Hidden Door. I <3 cheeseburgers and making beautiful things. I know a thing or two about AI, but it's people who matter. I am interested in many things.

Oh Paula, I would like a word.

Sometimes being a founder means staying up too late doing arts and crafts.

We'll be at #NYCC tomorrow with an exciting launch, come find us (or at least find our QR code to skip the waitlist)!

Having minor regrets about my chosen company name 😅

I'm so excited that Hidden Door is out in the world today!

We're thrilled to launch our roleplay meets fanfic platform, where we are making the tech, game, and biz in sync to let us all share more of the worlds we love, while rewarding the brilliant writers we admire.

Happy Saturday New York, I love you, I have some questions

I try not to amplify the awfulness, but this is just a straight up John Wick villain move

Okay, can anyone explain these fliers that someone mailed to my Brooklyn office from Dallas, TX? (Is it an ARG?)

Trying so hard to not write back and tell them how to fix their error

Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tost to me,
I lift my lamp beside the golden door!"

Just putting this screenshot here so I can point to it every time someone says “AI product design is not political”

London's Phantom Peak is an incredibly underrated immersive show!

It's like immersive theater meets LARPing meets a video game meets and escape room. Also, they have ice cream.

Today’s vibe brought to you by a Brooklyn hardware store window.

MoMA has an excellent 500 error page. More art errors, please.

Congrats to the Mayor of Bracket City on joining The Atlantic!

...seems right on point as a somewhat too intellectual competitor to the NYTimes Games.

For something completely different, the @hiddendoor.co team is in NYC this week, and today we took a trip to the Mossman Lock Collection and the Horological Society at General Society of Mechanics & Tradesmen of The City of New York in midtown. Highly recommended if you like obscure museums!

I came across this old photo I look at the National Museum of Scotland and it feels appropriate

I'll leave you with two more etchings that capture a feeling of a city more than anything else,

Side quest: I've spent the last 24 hours being mildly obsessed with the work of John Sloan, a turn of the century painter who captured the vibes of NYC life in the early 1900s.
