TLDR
Both Threvi and 222 use AI to match small groups of compatible people for in-person experiences. The core difference: 222 assembles a new group for each event. Threvi assigns the same group for recurring meetups over months. Research on friendship formation is clear: casual friendship requires ~50 hours of shared time, close friendship requires 200+ hours. A two-hour event at a wine bar provides less than 5% of what casual friendship needs.

The friendship app market has produced two distinct design philosophies. One optimizes for the quality of the first meeting — memorable venue, well-matched group, low awkwardness. The other optimizes for what happens after the first meeting — same group, recurring contact, friendship accumulation. Threvi and 222 are clear representatives of each approach.
Understanding which philosophy matches what you’re actually trying to accomplish makes the choice straightforward.
What 222 Is Built For
222’s thesis is that the first meeting is where friendship either starts or doesn’t, and a great first meeting in a memorable venue with genuinely compatible people gives friendship the best possible starting conditions.
The matching is thorough: a 30+ question personality quiz maps you to one of 16 types, and groups are assembled from compatible types. The venues are curated — wine bars, comedy clubs, art events rather than a generic restaurant. The product is well-funded ($12.6M from General Catalyst, Upfront Ventures, NEA, and YC) and designed to a high standard.
What 222 doesn’t do is anything after the event. A new group is assembled for each experience. The people you met last time may show up again if you both keep attending, but the platform doesn’t facilitate that continuity. You exchange numbers or you don’t. The rest is on you.
The geographic constraint compounds this: 222 operates only in LA and NYC. For the majority of adults living elsewhere, 222 isn’t a choice they can make regardless of how compelling the product is.
What Threvi Is Built For
Threvi’s starting point is the research: casual friendship requires approximately 50 hours of shared time (Hall, 2019). A single event, however well-curated, delivers 2–3 hours. That’s useful, but it’s less than 5% of what casual friendship requires. The question isn’t how good the first meeting is — it’s whether the same group keeps meeting.
We built Threvi around that insight. You’re matched into a group of 4–6 people at a compatible life stage, with compatible availability and interests. The app auto-schedules recurring meetups. The same group keeps meeting over months. That’s the accumulation mechanism friendship needs; it’s what the office used to provide automatically.
The honest trade-off: Threvi is a validation-stage product. 222 has more funding, a more polished product, and YC backing. If you’re in LA or NYC and want a well-funded, well-designed product right now, 222 delivers on that. The feature it doesn’t offer is the recurring same-group structure.
The Research on What Produces Friendship
Jeffrey Hall’s 2019 research in the Journal of Social and Personal Relationships is the most-cited work on this question. The finding: casual friendship requires ~50 hours of shared time, close friendship requires 200+ hours. The implication for app design is that any mechanism producing a one-off meeting — however high quality — contributes only marginally to friendship formation.
Group size matters too. Research on group dynamics consistently shows that groups of 4–8 are optimal for developing individual relationships within the group — large enough to relieve the pressure of one-on-one interaction, small enough that everyone can be present in conversation. Both Threvi and 222 operate in this range, which gives both an advantage over larger event formats.
The differentiating variable is repetition with the same group, which only Threvi provides by design.
The Verdict
If you’re in LA or NYC and want a high-quality first meeting with compatible people at a memorable venue: 222 is excellent. The matching is thoughtful, the product is polished, and the venue curation justifies the per-event price.
If you’re looking to build actual friendships — with the same group of people, meeting regularly over months, without having to organize every instance of it — Threvi is built specifically for that. From $12/month, available beyond LA and NYC.
The two products aren’t really competing for the same thing. 222 excels at first meetings. Threvi is built for what comes after.

PROS & CONS
Threvi
Pros
- The recurring same-group format directly addresses what research identifies as the core requirement for friendship formation — accumulated hours with the same people
- Auto-scheduling removes the coordination overhead that kills most adult social commitments before they start
- City coverage extends beyond LA and NYC, which are already among the most expensive and schedule-constrained markets
Cons
- Threvi is a validation-stage product — it doesn't have 222's funding depth or track record yet
- Cohort matching requires local density; small cities may not produce ideal group fits
- No free tier — participation requires a subscription commitment
PROS & CONS
222
Pros
- The curated venue approach — wine bars, comedy clubs — makes first meetings more memorable than a standard restaurant
- YC backing and $12.6M from General Catalyst, Upfront Ventures, and NEA reflects meaningful investor confidence
- 30+ question personality quiz produces more nuanced matches than demographic sorting alone
Cons
- LA and NYC only — 222 is irrelevant to the majority of US adults
- Assembling a new group each event means you're accumulating hours with different people every time, not with a consistent group
- Per-event pricing at $22.22 adds up quickly if you're trying to attend regularly
Q&A
Is 222 or Threvi better for introvert adults?
Both use small groups (4-6) which research shows is the optimal format for introverts — large enough to take conversational pressure off any one person, small enough to be manageable. The difference: 222 is a one-off curated experience with a new group each time, which means introverts have to 'start over' socially at every event. Threvi's recurring cohort model means familiarity builds with each meeting, which most introverts find less taxing over time.
Q&A
Does 222 or Threvi have better matching?
222's 30+ question quiz mapping to 16 personality types is more detailed than most friendship app matching. Threvi matches on life stage, availability, and interests — which prioritizes practical compatibility (can you actually meet regularly?) alongside personality. Both approaches outperform simple demographic matching. The more important difference is what happens after the match: 222's group exists for one event; Threvi's group recurs over months.
