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.
A screenshot of an article in The Canberra Times with the title "How sitting down to write her memoir led to a debut novel" by Paula McClean with the first sentence "Paula McClean's debut novel, The One Remaining, is the fictitious memoir of a fictitious novelist named Hilary Mason." The last line is fading to unreadable white, as I have not paid for access to the full article.

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)!
A pile of paper street posters in bright pink and orange that say WHERE FANFIC MEETS ROLEPLAY in a handwritten font. The bottom has a bunch of tearaways that are each a different trope. There's a hand and a scissor cutting them up.

Having minor regrets about my chosen company name 😅
A screenshot from a Google News search for "Hidden Door" showing articles about the company Hidden Door at the top and bottom. Between them are three articles about a Colorado coroner hiding bodies behind a "hidden door" in a funeral home. Words are hard.

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.

Check it out at hiddendoor.co

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
An excerpt from The Atlantic which says "The upshot is that an octogenarian Air Force retiree who spent half a century in his nation's service was not allowed to attend a party for a dog he essentially donated to the government and named after his dead wife."

Okay, can anyone explain these fliers that someone mailed to my Brooklyn office from Dallas, TX? (Is it an ARG?)
Mysterious fliers photocopied onto bright yellow paper. One is in some kind of code. Titles of others are “vampire prank weekend” and “endurance karaoke at club scintilla” and “pika season is coming are you prepared?”

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.

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'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.
John Sloan's painting "Sixth Avenue Elevated at Third Street" from 1928. It depicts the turning point of an elevated train with the sun setting over the city (and the Jefferson Market Library in the background), with several women holding hands and others crossing the street that seem drunk and happy.
