The Delta Office Hours
Each month, we bring 30 pre-seed and seed-stage founders together at The Delta Campus for a day designed to help you move faster on the things that matter most.
At the heart of Office Hours is access to seasoned operators, investors, and domain experts across fundraising, product, growth, brand, hiring, and more.
You’ll have the opportunity to book multiple 1:1 sessions throughout the day, diving deep into your current challenges and getting sharp, personalised input.
Please note: To secure time with specific mentors, you must book your 1:1 sessions in advance. While we try to accommodate everyone, unbooked sessions are not guaranteed and slots fill quickly.
This month’s mentors include:
