Turn any challenge into a rivalry worth watching.
RivalUP is where friends compete over anything — physical, creative, domestic or absurd. Call the challenge, raise the difficulty, prove it on camera and let every result fuel the next rematch.
Every challenge between friends dies the same three deaths.
Two friends argue over who runs 10k faster. A gym group dares each other to hit a lift. A couple disputes whose turn it is to do the dishes. It happens constantly, everywhere, and nothing serves it.
The loser shrugs
Enforcement runs on friendship, which is why the challenge quietly dies on day four. Someone forgets, someone disputes, and that is the end of it.
“I did it”
Unverifiable, so the challenge collapses into an argument instead of a result. Nobody can settle it, so nobody bothers starting the next one.
The best moment evaporates
The attempt, the fail, the win — gone. No record, no rematch, no audience, and nothing to show the friend who wasn’t there.
RivalUP fixes all three: clear stakes agreed in advance, proof everyone can trust, and a permanent, watchable record that makes the next challenge impossible to resist.
Five steps, under ninety seconds.
The gap between watching someone pull it off and answering “I can do that” is one tap. RivalUP keeps the energy moving from clip to challenge to rematch.
Call it
You state the challenge, the deadline and the consequence. The composer will not publish it until the success condition is binary and observable — “get fitter” is rejected, “run 5km under 25:00, watch visible” is accepted.
Take it
Others accept — or RivalUP it, lifting the challenge for everyone. A RivalUP re-opens confirmation for all parties; anyone who declines exits with no penalty.
Do it
You perform the challenge and capture proof. The required Proof Tier is enforced: in-app capture only, device attestation, or a scheduled live stream with a randomised liveness prompt where real value is decided.
Settle it
Resolved automatically against the proof record. Forfeits are scheduled, records update, Ups are awarded, charity commitments are collected. Missing the deadline is a loss by default — no argument required.
Watch it
The clip lands in the feed, carrying the challenge, the deadline and the result as native metadata. Fails are first-class content, and rank accordingly.
Watch a reputation move.
Of the five things RivalUP can put on the line, the Rival Record is the hardest one to explain and the most important one to feel. Walk one challenge end to end and watch what happens to four months of it.

You are Kai.
Four months of challenges behind you and a 23-day streak you have not broken. Tonight Toomas calls one.
Private group · 4 members
30 push-ups, unbroken, on camera.
The challenge is accepted. The record, the streak and the rivalry are now in play.
Take it, or RivalUP it.
Toomas says 30. You think you have more in you — and you think he does not.

Nothing was deposited, nothing was withdrawn, and nobody had to be chased for it.
Kai’s Rival Record
Earned here. Worthless anywhere else.Loss aversion on a status asset is one of the most reliably retentive mechanics in consumer software. A record earned slowly and lost quickly is why someone opens the app on day forty, not just on day four.
A Rival Record is only worth something if it cannot be farmed. Anything that touches it requires Tier 2 proof at minimum — in-app capture, one unbroken take, device attestation and synthetic-media screening.
Every challenge adds another result, streak and head-to-head chapter. The longer you compete, the more your Rival Record becomes a story only your group could have made.
Five ways to make a challenge matter.
Pick the stakes that fit the rivalry: pride, reputation, a forfeit, a prize or a promise to a cause. A challenge can carry more than one.
Performed on camera
The loser does the agreed forfeit — press-ups, cooking for the group, a video apology, a silly hat for a day. Chosen from a curated, pre-approved catalogue; free text is never permitted, and nothing risky, sexual or degrading can be entered.
Earned slowly, lost quickly
Completion rate, reliability, current streak, and head-to-head history against everyone you have ever competed with. Public, permanent, and worthless anywhere but here. This is the one the demo above walks through.
The platform’s own currency
Earned by completing challenges, extending streaks and being voted a standout attempt. Spent on cosmetic and functional extras that never touch an outcome or a proof. Never bought, never sold, never traded between people.
A bigger stage, a real reward
Brand challenges put up prizes for the people who can deliver. Entry stays free; winning comes down to performing when the camera is on.
Turn commitment into impact
Attach a donation to your own result: if I do not run this, €20 goes to a cause I have chosen. The promise adds weight to the challenge and sends the contribution directly to a registered charity.
The test we hold ourselves to. The stakes are real when they make you care about the result: protecting a 60-day streak, beating your oldest rival, performing the forfeit or delivering when your whole group is watching.
RivalUP is not a passive habit tracker. It is competition with memory, personality and another round waiting.
Playing stays free. The competition stays open.
Create a challenge, join one, prove your result and call the rematch without paying to take part. Ups are earned through participation, not bought.
RivalUP grows around active communities: friend groups, creators, clubs, workplaces and brands that want people doing something together instead of scrolling past it.
Four rules, enforced in code
- Ups are never purchasable, and never redeemable for anything of monetary value.
- Prizes are always won by performing, never by being drawn at random.
- No user may ever fund a prize another user can win.
- A charity commitment has exactly one payee: a registered charity.
These boundaries keep every RivalUP result tied to participation, skill and proof.
Run it for your people.
The same product, with an admin layer on top: private groups, team challenges, forfeits, records, proof, reporting — and no advertising anywhere near it.
Employers, gyms, running and climbing clubs, universities and amateur leagues already have the social structure. RivalUP supplies the consequence layer that makes a wellbeing programme something people actually do past week two.
Admin console, private groups, participation reporting, a curated forfeit catalogue, and per-seat pricing above twenty people.
We are choosing a small number of first partners to build this with, ahead of general availability. Early accounts shape the console.

Be in the first group.
RivalUP launches on iOS and Android. Bring your friend group — the product is built for three people, not one.
We’ll email you once, when there is something to open. No newsletter, no drip campaign.
Join the waitlist
We’re open to an investment partner.
RivalUP is raising to fund the first phase, and we are having those conversations now. Round size, structure, the cost model and the plan behind them are shared directly rather than published — start a conversation and we’ll send the full concept document and a time.
