Happily nicknamed
“The Startup Party of the Year”
10th Anniversary · Diamond Edition
September 15, 2026
The 10th anniversary of Party on a Tuesday deserves more than just a party. So we built an experience.
Every year on the Tuesday of Colorado Startup Week, this is the night people remember for years. Conversations that turn into something real. Strangers who feel like old friends by midnight. DJ sets that keep you on the dance floor and make you forget you have a 9 AM on Wednesday.
This year: a brand new venue, multiple rooms, and more surprises than we're going to spoil here.
In the past, Party on a Tuesday has had a 900+ person waitlist. Apply early.
The Experience
The ATTIRE
Diamond Disco
This year, we're celebrating 10 years of Party on a Tuesday with our most stylish theme yet.
Think elevated cocktail attire with a modern disco twist. Sleek dresses, tailored suits, rich textures, metallic accents, crystal details, and just the right amount of sparkle. Whether your style is timeless, bold, or somewhere in between, Diamond Disco is all about dressing up, having fun, and bringing a little extra shine to the celebration.
Go all out, keep it classic, or simply add a touch of shimmer. However you interpret Diamond Disco, this is the night to wear THAT outfit.

About
Party on a tuesday
What began in 2015 with two friends, Paul Foley and Pascal Wagner, wanting to gather the community for Colorado Startup Week has grown into one of Denver's most anticipated nights of the year.
The idea was simple and the conviction behind it strong: the startup community deserved more than another happy hour. It deserved a real party. A night worth getting dressed up for. A room full of people who actually want to be there.
A decade later, it's something else entirely. A new venue every year. An intentional guest list of founders, investors, operators, and creatives. Live music, DJ sets, and entertainment that keeps the floor moving all night. Conversations that turn into companies. Strangers who feel like old friends by midnight.
A community of people who plan their September around it.

This isn't a trade show floor. No booths, no pitches, no standing behind a table waiting for someone to walk by. Your brand becomes part of the experience itself: the drink in someone's hand, the reception before doors open, the photo they post the next morning.
From logo placement to full presenting partnership, there's a tier built for your brand. Not sure which one fits? Just reach out and we'll figure it out together.
