Slate at Founders Tower
5900 Mosteller Drive, 20th Floor, Oklahoma City, OK
240 Capacity
Some venues give you a room. Slate at Founders Tower gives you a landmark.
Perched on the 20th floor of a National Historic Landmark in Oklahoma City, Slate is the city's most distinctive luxury event venue — 360-degree panoramic views of the OKC skyline, two distinct spaces, and an atmosphere that is boutique, elevated, and entirely unlike anything else in this city.
The Penthouse Lounge is grand, modern, and commanding — floor-to-ceiling views for events up to 150 guests. The Scarlett Lounge is intimate, sultry, and sophisticated — perfect for gatherings up to 40 guests. Combined capacity of 240.
Weddings, corporate events, client mixers, private celebrations, milestone moments of every kind. Full bar service, flexible catering, in-house décor, photo booth, and all-inclusive packages available. Private chef experience and VIP concierge services launching late summer 2026.
This is not just an upscale venue in Oklahoma City. This is the one you will remember.

Slate Experience for our BLAC, Inc. Annual Gala
— An Eventective User
from OKC
Facility-We had 142 guests that attended our Annual Fund raising/recognition event, seating was a little tight, but the intimate ambiance was GREAT! The mother daughter bar tenders were fantastic! Our meal was catered by Vickie’s Kitchen & Catering another fantastic job! The BEST part was our event coordinator Brooklyn J., her attention to detail and suggestions were spot on, very easy to work with. Out of a 5-star rating I’d give her a 10!!! If I was planning any future events whether personal or business oriented, she would be my first choice on returning to the Slate. I can’t say enough on my appreciation for her kind spirit.
