Flipper Zero

Key numbers

The product

The Flipper Zero is a pocket-sized, open-source multi-tool for exploring and pentesting wireless protocols. It packs sub-GHz radio, 125 kHz RFID, 13.56 MHz NFC, infrared and iButton capabilities into a toy-like case with a 1.4-inch monochrome LCD. A dual-core STM32WB55 microcontroller and microSD slot run an open-source FreeRTOS firmware. An animated dolphin avatar gamifies use, evolving as owners complete tasks. GPIO headers and BadUSB support let tinkerers extend it with add-on modules.

How they did it

The project began in 2019 when Pavel Zhovner and Alex Kulagin, working out of a hackerspace, imagined a Tamagotchi for hackers. A Kickstarter campaign launched on 30 July 2020 with a modest $60,000 goal. It closed 30 days later with $4,882,784 pledged by 37,987 backers, or 8,138 percent of target. That instant demand collided with the global chip shortage, forcing repeated PCB redesigns as components grew scarce. Mass production finally ramped in late 2021, and the first shipments reached backers in early 2022. Flipper Devices grew from a small hackerspace team into a company, later forming Flipper FZCO for global fulfilment. Its community has since grown past half a million people. Despite import debates in Canada and sales limits on some marketplaces, the device remains a flagship of open-source hardware.

Why it worked

• Open-source firmware and hardware invited a huge community of modders and developers
• A toy-like design made a serious security tool friendly and socially acceptable
• Kickstarter overfunded 8,000 percent, proving massive pentest-hobbyist demand upfront
• Handled chip-shortage delays transparently, keeping 38,000 patient backers loyal
