The 3-Way Handshake: How SoulFire Makes Every Introduction Mutual
SoulFire's 3-Way Handshake ensures every social introduction at a FirstMove event is mutually desired. Here's the mechanic that eliminates cold approaches entirely.

The name might sound technical. The experience it describes is entirely human.
The 3-Way Handshake is the core social mechanic of FirstMove's SoulFire events — and it's the reason people who attend SoulFire describe it as unlike anything else they've experienced at a social event in London.
What Is the 3-Way Handshake?
In network communication, a handshake is the process by which two parties confirm they're ready to communicate before any actual data is exchanged. It's a mutual confirmation protocol.
FirstMove has adapted this concept for social interaction. The 3-Way Handshake is a three-stage process that ensures every introduction at a SoulFire event is mutually desired before it happens:
Stage 1 — You indicate interest: when you see an attendee's profile in the FirstMove app and want to meet them, you indicate interest. This is private — they won't be notified that you've done so.
Stage 2 — They indicate interest: independently, they look at your profile and indicate interest in meeting you. Again, this is private. Neither party knows what the other has done.
Stage 3 — The app confirms and connects: when mutual interest is registered, the app confirms the match to both parties and facilitates the introduction.
The "3-Way" refers to these three stages: your expression of interest, their expression of interest, and the app's confirmation and connection.
Why This Changes Everything
The cold approach — walking up to someone you don't know without any signal of receptivity — is the single biggest source of anxiety in social environments. Even highly socially confident people experience some version of it. For many people, it's the reason they leave events without having met anyone: the cost of potential rejection feels too high.
The 3-Way Handshake eliminates the cold approach entirely. There is no moment at a SoulFire event where you approach someone without already knowing they want to meet you. The confirmation happens before the approach. The approach is therefore not a risk — it's a response to an invitation.
The psychological shift this produces is not subtle. It changes the entire phenomenology of attending a social event.
The Asymmetry Problem in Social Events
Standard social events have an asymmetry problem: the person who approaches carries all the social risk. If the approach isn't welcome, the cost falls entirely on them. The approached party has the power — they can engage or disengage at will.
This asymmetry produces predictable outcomes. It reduces the frequency of approaches (most people aren't willing to bear the risk). It advantages the socially assertive over the genuinely interesting. And it creates an environment where chemistry between compatible people often never has the chance to emerge — because neither party initiates.
The 3-Way Handshake is a solution to the asymmetry problem. By making interest-expression private and confirmation mutual, it removes the risk from both sides simultaneously. Neither party is exposed. Both parties are empowered.
What the App Shows
During a SoulFire event, the FirstMove app shows you a view of other attendees — their photos and a brief profile. You can scroll through, get a sense of who's in the room, and indicate interest in the people you'd like to meet.
The app doesn't show you who has indicated interest in you before the match is confirmed. This is a deliberate design choice — knowing who's interested in you before you've formed your own view would introduce bias and reduce the authenticity of the matching process. You form your own view first.
When a match is confirmed, both parties receive a notification. The nature of the notification — who you matched with, their name and photo — gives you a clear and specific social direction. You're not hoping to run into someone. You know who to look for, and you know they're looking for you.
Multiple Handshakes Per Evening
The system is designed to produce multiple matches per attendee over the course of a SoulFire evening. As the evening progresses and more attendees indicate interest, more matches are confirmed. The social experience has a building quality — the introductions come in waves rather than all at once.
This means that even if your first match produces a conversation that runs long (a good problem to have), there are more connections developing in the background. The evening rewards patience and presence.
Privacy Throughout
Every stage of the 3-Way Handshake is private until the mutual confirmation. Your interest expressions are never visible to the people you're interested in unless and until the match is confirmed. Declined or unreciprocated interest disappears without trace.
After the event, the connection information is yours to keep — contact details and the record of who you matched with — but profile data is governed by FirstMove's Ephemeral Profile system. What happened at the event stays appropriately bounded.
The 3-Way Handshake in Practice
At a SoulFire event, the 3-Way Handshake tends to produce the first confirmed match within the first 30–45 minutes. That initial match notification — "You've connected with [name]" — sets the tone for the rest of the evening.
From that moment, you're navigating the room with a purpose and a confidence that's qualitatively different from the usual social event experience. You're not hoping someone finds you interesting. You already know someone does.
That knowledge changes everything.
