Efrem Arpa

Hi, I'm Efrem. I'm building Pluribox (https://pluribox.com), a modular selling system for digital products that lets you add checkout, reviews, forms and digital delivery to the website you already own, without building a separate store or sending buyers away.

My background is in economics and finance, and I'm also a musician who wanted a cleaner way to sell music and digital goods from websites. Following the build here and sharing what I learn.

Products

Pluribox
Sell digital products on your own site. No redirects, no middleman. Imagine if any website could instantly sell digital products without rebuilding it. The whole purchase happens in an overlay on your site, so buyers never get redirected away. The part that matters most: you stay the merchant of record. Pluribox connects your own Stripe account, so payments flow directly to you and your buyer relationship stays yours. You are not handing your customers, your payouts, or your account to a platform that can gate or freeze them. Pluribox never holds your buyers' funds. Join the waitlist!
Coming soon...
