Closed Beta · ApplyNetworking Club
A trust-first home for people building what matters.
Not a social app. Not a job board.
Tell Cleo who you need. She assembles the Room.
Built around demonstrated reliability, not inherited proximity. A home for founders, investors, operators, and mentors. Open daily.
The Premise
Reliability becomes more valuable than reach.
“In a vertical curated tightly enough that members can recognize each other, reliability becomes more valuable than reach. Vesper engineers that reliability into compounding social currency, inside a network architected so it actually compounds.”
The Problem
Founder networking is structurally broken.
Every existing channel fails founders in a specific, compounding way.
Access is gated.
Most checks close through people the firm already knew. Cold outreach without that proximity rarely closes.
Signal is flattened.
Titles travel. Track record doesn’t. Build-in-public broadcasts, but no reputation layer sits underneath.
Trust isn’t calibrated.
Reliability under prior commitments, the signal that matters most, doesn’t surface for founders evaluating investors or for investors evaluating founders.
Product
Three coordinated discovery loops.
Three surfaces, three intent profiles, three frequencies. Together they answer every networking job a founder does.
HIGH-INTENT
Cleo plans a Room.
An AI concierge that orchestrates introductions and small-group Rooms. Plan mode for "I need someone." Explore mode for "what’s happening this week."
Typical cadence: 2–5× per week.
DAILY DEAL FLOW
Founders broadcast. Investors source.
A ≤60s video feed where builders post real progress. Investors get the same data in a Pipeline grid, filterable by stage and sector, with Trust Score on every card. Posts rise on the connection requests they earn.
Use: daily.
WHAT’S NEARBY
Horizon, the now-hub.
Where Cleo plans, Horizon catches what’s already happening. Public events worth showing up for, nearby founders and investors selected for you, and an in-app map of the ecosystem around you. The push to actually be in the room.
Use: when a free hour opens up.
How It Works
From conversation to confirmed Room.
Cleo doesn't browse. She plans. Type what you're looking for, answer two or three questions, and the network assembles itself. Every match comes with a transparent reason. Once the Room confirms, everyone in it lands in a shared group chat for coordination (location, timing, last-minute changes) until the day of.
The plan emerges. Time, place, group size.
The algorithm explains itself.
Two Bets
Same problem. Different bet.
The Lightweight Bet
Series.
AI-mediated intros over iMessage. Text who you want to meet, get a carousel back. Backed by Pear VC + Steve Huffman, live across 750+ campuses. Lightweight, fast, easy to adopt.
The Depth Bet
Vesper.
Trust infrastructure. Persistent identity. Relational depth. The graph that knows who showed up, who followed through, who hosted. Slower to launch. Harder to imitate.
An iMessage carousel can be cloned in a weekend. A graph that knows who showed up, who followed through, and who delivered cannot. That history takes years to accumulate. It doesn’t walk out the door when a member leaves.
Interfaces get cloned. Graphs compound.
What's Been Tried
The pattern is consistent.
Every attempt has solved one dimension while missing others. A clean read on the landscape:
Lunchclub
AI matching without behavioral signal is just shuffling profiles.
Polywork
Profiles don’t generate sessions. Flow does.
On Deck
Paid-membership scale is fragile when gating stops curating.
Cocoon
Small-group chat couldn’t retain on its own.
Pavilion · Startup Grind
A community is not the same as a product.
Build-in-Public on X
Audience works. The reputation layer is missing.
Why Now
The bottleneck is shifting from access to signal.
The traditional entry point for ambitious talent is breaking down. More high-potential people are open to building earlier. The systems they’d use to find collaborators weren’t designed for the shift.
The shift.
The constraint.
The bottleneck.
“As institutional signals weaken, interpersonal trust becomes the new infrastructure. Vesper makes that trust legible, scalable, and actionable.”
The Architecture
Three mechanisms compound the trust.
TRUST SCORE
Reliability surfaces on profiles and weighs every match. Built from behavior: attendance, peer ratings, rooms hosted, intros that landed. No purchase path.
Ratings stay private. The aggregate Trust Score shifts over time; the rater and score never surface. Flake reports get cross-checked against geo logs from the room location, so “they didn’t show” has to match the GPS. Patterns of unsubstantiated reports get a quick human review.
MATCHING ALGORITHM
Selects for demonstrated reliability, weighted at every match decision.
CLEO + ROOMS
Not a chatbot. The orchestration layer that makes everything else navigable. An AI concierge distributing trust through curated intros and small groups of two to six. In-person first, remote when needed.
Direct DMs work only with peers on your network — people you’ve met through a Room or accepted as a connection. Cold outreach routes through Cleo’s intro flow, rate-limited per day, so inboxes stay signal-heavy.
Consider a 23-year-old engineer deciding whether to leave a stable role to build. They don’t want to do it alone, but they don’t trust cold outreach. On Vesper, they spend months watching how potential collaborators actually work. By the time they reach out, the question isn’t “are you legit?” — it’s “what should we build together?”
