The most common words we hear from clients running a demo day for the first time:
"The flow got tangled and the entire presentation time felt chaotic."
"Pitch timing slipped and all the later teams ran behind schedule."
"Investors came to exchange cards but the networking area was too cramped."
A demo day is not just a presentation event. A startup's year of work ends in seven minutes, and the first impression investors form in that time directly translates into follow-up meetings. A single operations miss becomes a reputation issue in the ecosystem.
1. Pre-event (D-7 ~ D-1)
① Finalize the pitch order
The pitch order is a strategy in itself. When you arrange the teams thoughtfully by their product category and pacing, the whole event plays out like a performance — engaging from start to finish rather than dragging in the middle.
② 7-minute pitch = 5 min talk + 2 min Q&A
Always run a full timer rehearsal. Without it, presenters tend to ignore the on-stage countdown and end up overrunning, no matter how many times you remind them.
③ Pre-check slide ratio and fonts
Font corruption between the podium computer and the presenter's own laptop, video codec compatibility, and slide ratio consistency — standardize all of it in advance so nothing breaks on the day.
④ Back up presentation assets
Back up every pitch deck to both a USB drive and the cloud. Last-minute revisions are common, so set a hard cutoff and communicate it clearly.
2. On the day (D-Day)
⑤ Sound check at least 2 hours before call time
Check wireless mic channel interference, lapel mic batteries, and monitor speaker output — each one in isolation.
⑥ Stage flow rehearsal
Walk the speaker entry → presentation → exit flow at least once. Agree on the waiting chair position backstage and mic hand-off timing.
⑦ Share the MC cue sheet
Give the host a one-line intro for each team, expected questions, and prepared lines for unexpected situations — all before the event starts.
⑧ Agree on camera angles in advance
For group photos, coordinate with the photographer beforehand. For the sketch video crew, it helps to align on whether they can step onto the stage for certain shots — those pre-arranged moments produce far richer footage.
3. Networking & settlement (D+1 ~ D+7)
⑨ Business card collection system
Prepare a QR business card or digital collection form in advance. Paper cards alone make post-event matching very difficult.
⑩ Share photos and video within 24 hours
Deliver the top 10 key shots to the accelerator's team by the next morning — the follow-up PR impact is significantly larger.
⑪ Collect participant feedback
Beyond operational satisfaction, checking which investors led to actual meetings by D+7 is what improves the next iteration of the event.
⑫ Fix external vendor settlement deadlines
Finalize payments with the camera crew, catering, sound, and MC vendors at least one week in advance of the due date.
What it means when MotionSense runs a demo day
We've run demo days with KSTP, Seoul National University, KAIST, Sopoong Connect, and many other partners. Our work isn't just filming and streaming — it's going through these 12 checkpoints together with your operations team, item by item.
In the next post, we'll dive into the design and video production side of running a demo day.
If you've ever finished a demo day thinking "isn't there a partner who just handles all of this properly," please reach out.
