Why it is new

What exists today, and what this does differently

What is new

Mutual reveal apps exist off chain; FHE based mutual match was not found live.

Closest things out there

Off chain crush apps.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

The whole app, not a starter kit.

The complete Quiet Match app: founders in a cohort say who they would build with, picks are encrypted on Fhenix and only mutual picks are ever revealed, with a USDC paywall, host view and round runner agent built in.

How it earns for you

Small groups are free. Cohorts buy a one time pass, programs pay yearly, all in USDC. Picks and the reveal are never gated.

Small groupFreeUp to 12 people, one round a week, encrypted picks, Friday reveal

Cohort pass$29 once per cohortUp to 60 people, booked intros, more mutual questions, round history

Program$199 a yearMany cohorts, custom questions, anonymous totals export for the host

The owner sets tier prices and which features are gated. Fhenix gas and hosting are a few dozen dollars a month at cohort scale.

Prices are yours to set. Illustrative, not a promise of income.

The pitch, ready

Say who you want to build with. Hear it only if it is mutual.

Problem: In cohorts and small communities people avoid asking to work together because a no is awkward and public, so good pairs never form.

Solution: Picks are encrypted with FHE on Fhenix, a cap stops fishing, and one batch reveal shows only mutual picks. Even the host cannot read a one sided pick.

Why now: FHE on Fhenix makes it possible to compute a match without anyone, including the operator, reading the inputs.

Market: Accelerators, residencies, bootcamps, hackathons and any community where two people both have to opt in.

The ask: Pilot cohorts and program hosts who want cofounder pairing without awkward asks.

Funding is never guaranteed. Check each program's rules.

For hackathons and demo days

Your 2 minute demo

Home: meet Ji-woo in the Seongsu loft, round 4 closes Friday 18:00
Pick: she picks Tomás, sees the cap of 3 and seals one pick
Agent (owner): round 1's timing leak and the fix to a single batch reveal
Reveal: skip to Friday 18:00, the lockbox opens because Tomás picked her too
Pairs: say hi to Tomás, then show the intro booking gated behind the Cohort pass
Roster (owner): the host sees counts only, never who picked whom
Revenue (owner): edit the paywall and watch the Plans sheet change, incoming USDC payments
Roadmap (owner): question packs and the private yes API as priced builds

Many hackathons require code written at the event. See the Regatta Boardfor each race's rule.

BLUEPRINT

Why it matters and how it really works

The need

In cohorts, teams and small communities, people want to say they would like to work with someone but avoid asking because a no is awkward and public. Good pairs never form because nobody wants to go first.

What exists and what is new

Mutual reveal is an old idea. Off chain crush and match apps already do it, but the operator's server sees every pick. What we did not find live is mutual matching where picks are encrypted with FHE on Fhenix, so the match is computed without anyone, including the host, reading a one sided pick. The mechanic is familiar; the privacy guarantee is the new part.

The data it runs on

A host roster of names and photos kept offchain, encrypted yes or no picks per founder pair submitted to a Fhenix contract, a host set pick cap and reveal time, and the mutual results decrypted only for the two people in each pair.

1.The mission

Let people say who they want to build with, safely, so good pairs form without anyone risking a public no.

2.Why people can't resist it

No awkward no A one sided pick is never revealed, so asking costs nothing.

Friday reveal Everyone's page changes at the same moment, which turns the reveal into a cohort ritual.

Fresh rounds Picks reset weekly, so people can change their minds without baggage.

The host cannot peek Even the organiser cannot read picks, which is what makes people honest.

3.How it works for real

Roster: The host uploads the cohort roster offchain and sets the pick cap and reveal time.

Encrypt: Each founder's picks are encrypted in the browser with the Fhenix FHE library and sent to the round contract.

Cap: The contract counts picks under encryption and rejects any beyond the cap.

Compute: At the deadline it computes an encrypted AND for each pair: true only if both said yes.

Reveal: In one batch transaction, each founder gets a permit to decrypt only their own mutual results.

Reset: A new round opens weekly and old picks are discarded.

4.Cost per use and pricing

FHE operations cost more than plain ones. For a cohort of 12, a round needs 66 pair checks; on current Fhenix testnet economics this is cheap, but mainnet gas for FHE should be measured before pricing. Hosting the roster and pages is a few dollars a month.

Small group Free

Up to 12 people, one round a week.

Cohort $29 per cohort

Up to 60 people, intro booking, host dashboard with counts only.

Program $199 a year

Many cohorts, custom questions such as who would you hire, and an export of anonymous totals.

5.Growth loop

Each cohort that uses it runs a visible Friday ritual. Founders carry the habit into their next program or team, and hosts recommend it to other programs.

6.Risks and guardrails

Timing leaks: Per pair reveals let people infer one sided picks. Reveals happen in one batch for everyone.

Fishing: Picking everyone reveals who likes you. A cap is enforced inside the encrypted contract.

Small groups: In a group of three, a missing match says a lot. The app warns hosts below eight people.

Pressure: A match could feel like an obligation. The copy says a match is a mutual yes to talk, nothing more.

8.Where this is going

Now
Cofounder matching for one residency cohort.
Next
Other mutual questions: who would you hire, who would you mentor, who would you co-write with.
Later
Matching across cohorts and programs, still with no operator able to read picks.
Far
A private yes layer any community app can call when two people both have to opt in.
