Dolphin

Dolphin is a startup in a box.

Dolphin is a startup in a box. Dolphin is a web-app builder for aspiring startup founders to ship to their first customers in an hour. Dolphin builds startups in one pass. Dolphin can setup subscriptions, AI assistants, complicated database updates, integrations, messaging, and more. Teddy and I have spent thousands of hours building complicated web apps, and we’ve developed strong opinions on how to architect them. That’s why Dolphin is so powerful: rather than give an AI free rein, we constrain it to the Dolphin architecture. Constraints breed creativity. We designed the Dolphin architecture so that, when an AI works with it, its outputs are correct, secure, and scalable.

Company Launches
Zenobia Pay - Payments for luxury
See original launch post

Hey! We’re Teddy and Ryan, co-founders of Zenobia Pay.

Zenobia Pay enables luxury brands to accept pay-by-bank and avoid fraud, chargebacks, and credit card fees.

Online credit card payments are expensive and rife with fraud. Fees account for 3+% of transaction volume, and high-ticket items account for more than a third of the 100 million annual chargebacks in the US.

With Zenobia Pay, payments cost only 1%, clear instantly, and are protected with a fraud chargeback guarantee. Customers link their bank to their own hardware, where it’s stored locally in a secure enclave. Merchant sites never see sensitive tokens or account numbers.

Founders Theodore Li and Ryan Prendergast started Zenobia Pay with a mission to make it 3x cheaper to transact online, bypassing the senselessly high credit card interchange fees that aren’t normal anywhere outside the US.

If you sell goods online for >$200 and want to 3x lower your fees, email us at merchants@zenobiapay.com. View our site at zenobiapay.com
