A high-stakes 1:1 has a pre-game: you are checking your frame, your light, your notes. The last thing you want is the investor dropping into the room while you are still mid-setup. That is what the waiting room is for — and in 4K Chat it is on by default, so the default behavior is already the right behavior.
Waiting room is on by default — use it
When a guest clicks your link, they land in a waiting room, not in your face. You see that they have arrived; they see that the call exists and they are next. Nothing starts until you admit them. This is not a premium gate or an upsell — it is how the call works, because a call where the host controls the start is a better call for both sides.
Admit on your cue
The rhythm that works: join your own room a few minutes early, do the 60-second light check, frame the product if you are showing one, then admit the guest when you are actually ready. The guest experiences a call that starts composed, not a call that starts with you saying "sorry, one second" while adjusting a laptop.
Link hygiene
Treat room links like calendar invites, not like your phone number. A link you sent for last week's call should not be the link for this week's call — reuse means an old guest with an old link can knock on a new conversation. The habit is cheap: start a fresh room from Start a Call for each meeting, and send that link or room code. It takes seconds and it keeps each conversation its own room.
Send the link through a channel you already trust with that person — email, a direct message. The waiting room is your second line of defense: even if a link travels further than you intended, nobody enters until you recognize them and let them in.
What your guest needs (almost nothing)
Guests need no account and no install — the link opens in a modern browser and they are in the waiting room. Their camera is optional: someone can join audio-first and turn video on when they are comfortable. Fewer steps for them means the call starts on time, which is the whole point.
