Three steps for the sender. One tap for the receiver. Nobody types an account number at any point.

THE SHIFT

Anywhere you can express your intent, you can pay.

Payflip is more than an app.

Web claim links

Opens in any browser, any country. Nothing to download.

02

Our app

Face ID, one screen, three taps.

03

Chats and DMs

Money in the conversation you're already having.

04

QR on a counter

Scan to pay a person. No terminal to buy.

05

Voice and AI agents

Say it out loud. Or let an agent pay. Add our bot to group chats.

06

Anyone's app

Other companies build payouts on top of us.

One behavior. Infinite surfaces.

100% RETURN GUARANTEED

Payments automatically undo.

Every other rail treats a failed payment as the sender's problem. We make it a state transition. That single design choice opens markets nobody else can serve.

MARKET OPPORTUNITY

Why this is worth money.

Unclaimed money is a real, budgeted cost. In banking, corporations lose millions to escheatment filings, stale checks, and dead wires.

~91%

US class-action settlements see a median claim rate near 9%. Cheques expire in 60–180 days and the remainder escheats to the state.

Payflip eliminates unclaimed liability entirely.
Settlement & Claims

~91% of distributions go unclaimed and escheat. We return them instead.

Gig & Task Payouts

Workers locked out of accounts still holding balances get paid via text or handles.

Prizes & Bounties

Tournament and bounty payouts that expire, bounce, or never reach a winner return safely.

Airdrops & Grants

Already claim-shaped. Vesting cliffs and expiry map onto cryptographic TTL exactly.

Positioning: Payflip is the payout rail for money that might not get claimed. No wallet, no bank and no card network is built for that.
