About

Started in 2024 and previously known as Software Day, Mercury Fund Day is a monthly series driving the support, inspiration, and connections needed to help startups on their path to rapid, sustainable growth. Each month, Mercury Fund Day includes office hours (by application), a keynote session, elevator pitches and networking.

Mercury Fund Day at the Ion isn’t just an event series- it’s a catalyst for growth and collaboration. Don’t miss this opportunity to be part of Houston’s thriving tech ecosystem.

Typical schedule:

  • 1:00 – 1:30 PM:  Check-in for Mentors & Participating Software Companies
  • 1:30 – 3:30 PM:  Private Office Hour Meetings with Mentors (2, 30-minute sessions per startup)
  • 4:00 – 5:00 PM: Panel + Startup Pitches (Public Portion of the Event)
  • 5:00 – 7:00 PM: Networking at Second Draught, brought to you by Gunderson Dettmer

Startups Apply

Each month, we select between 8-15 software startups for 1:1 mentor meetings.

Over the course of 2 hours, software founders are paired with leading mentors from the Mercury network who have expertise in high-growth software innovations. Those same startups will give an optional 60-second elevator pitch to all attendees after the public keynote session.

The ideal profile of a company for this mentorship program is a pre-Series A software startup that is in the early stages of revenue generation. Startups are chosen a week before each event. Apply at any time, but deadlines are communicated for consideration into each month’s event.
