Popsy is a global leading marketplace for refurbished electronics, providing customers with high-quality, affordable tech products up to 70% off while reducing electronic waste. With a strong focus on sustainability and social responsibility, Popsy offers a wide range of refurbished smartphones, tablets, laptops, and other electronics from top brands. By partnering with certified refurbishers and ensuring rigorous quality control standards, Popsy guarantees that all products sold on their platform are fully functional and come with at least 12 months warranty. As a result, Popsy has become a trusted destination for consumers looking for an eco-friendly and cost-effective alternative to buying new electronics.
The future of buying Electronics is buying refurbished. Refurbished products are significantly cheaper than newer alternatives and, when done responsibly, far better for the environment. Popsy is leading this revolution by creating a marketplace for high-quality refurbished electronics. By reducing e-waste, we’re building a circular economy that helps keep our environment clean and healthy. For example, each iPhone sold on Popsy saves 70,000 liters of water – that’s enough to fill a small pool!
With Popsy, you don’t have to choose between paying less or being more environmentally friendly; you can do both.

Runa is pioneering a first-of-its-kind payment rail capable of sending and accepting digital value at scale. With Runa, companies can pay the people they serve in any form of digital value, anywhere, instantly.
Legacy payment mechanisms struggle to adapt to low-volume, high-velocity transactions both locally and globally, such as sending payouts to gig workers, creators, or sending rewards to customers or employees wherever they are.
Runa’s infrastructure and network facilitates payouts to these recipients, helping businesses expand their reach, retain their users while modernizing the way in which they manage and transfer money: instantly, internationally, and free of charge for the senders and the recipient.
Operating in more than 30 countries and 18 currencies, hundreds of leading companies rely on Runa to power instant, flexible global payouts including Sodexo, TopCashback, Perkbox, Vodafone, Coinbase and Globetopper.
We are committed to providing a hiring and working experience in which all people feel they are equally respected and valued regardless of race, religion, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
