What Dangerous Things does

Dangerous Things, founded in 2005 and based in Seattle, Washington, designs, manufactures, and sells RFID/NFC human chip implants and related accessories to a global community of biohackers, electronics hobbyists, security researchers, and access-control enthusiasts. The product portfolio spans three form factors — injectable x-series implants in bioglass, flexible flex-series implants in biopolymer, and rigid d-series bioresin disc implants — plus the Magic Ring v2 wearable, the xG3 injectable biomagnet, and complementary hardware accessories such as the KBR1 reader, ACR122U reader, Proxmark3 Easy, field detectors, access controllers, and the FauxFOB/Blue Bambino cloning tools. Core technology rests on NXP (NTAG, Mifare, DESFire) and Atmel (T5577) transponder chips operating at 125 kHz (LF) and 13.56 MHz (HF/NFC), encapsulated in biocompatible materials (bioglass, USP Class VI biopolymer, ISO 10993-tested bioresin) and sterilized via ethylene oxide gas.

Revenue is generated entirely through direct-to-consumer one-time product sales via a WooCommerce storefront, with no recurring subscription layer and no enterprise/B2B channel. Prices range from $25 for an entry-level xNT or xEM chip to $564 for a top-of-line dUG4T bioresin disc bundle, with most implants priced $100-$300. Installation is performed by a global network of vetted professional body piercing and modification partners; Dangerous Things does not operate installation clinics itself. Marketing is community-led, anchored by an active forum, a YouTube channel of tutorials and product demos, organic social media (Facebook, Twitter, Instagram), and extensive technical documentation. The company ships globally via DHL with documented reach into North America, Europe, Australia, and Latin America, and maintains shipping restrictions in several jurisdictions including China, Russia, Iran, and Turkey. Dangerous Things has raised no disclosed institutional capital beyond a 2013 Indiegogo crowdfunding campaign for the original xNT, and operates as a founder-owned, bootstrapped micro-business with 1-10 employees under CEO and founder Amal Graafstra.

Others

• SparkFun Electronics: Electronics retailer focused on maker, hobbyist, and education markets. Similar DTC model for electronics kits, components, and development tools, but without Dangerous Things' implant specialization.
• Adafruit: Open-source hardware and electronics retailer serving the maker community. Operates a similar direct-to-consumer retail model for DIY/biohacker customers, but does not specialize in implantable products.

Broad incumbents

• HID Global: Large access control and identity solutions provider serving enterprises globally. Comparable to Dangerous Things' access control use cases (xEM, xMagic cloning) but with traditional card/badge solutions and a much larger installed base.
• NXP Semiconductors: Major semiconductor manufacturer whose NTAG, MIFARE, and DESFire chips are the technological foundation of Dangerous Things' implants. Operates broadly across secure connectivity but does not sell finished implants, defining the platform on which the company builds.

Direct peers

• Biohax International: Swedish biohacking company offering RFID/NFC chip implants for humans. Directly competes with Dangerous Things in human augmentation with similar transponder technology and overlapping biohacker/transhumanist customer base.
• VivoKey: Platform offering APIs and developer tools for secure authentication on implantable chips. Operates in the same implant technology space as Dangerous Things and is both a partner and adjacent competitor in the developer-tools layer.
• Fidesmo: Multi-application contactless smart card platform supporting MIFARE, Java Card, and GlobalPlatform. Partners with Dangerous Things on developer kits and competes for the same developer/customer mindshare in card-based and implant-based authentication.
• Walletmor: UK/Polish company selling payment-enabled NFC chip implants. Competes head-to-head with Dangerous Things' x-series implants, particularly in payment and access-control use cases across Europe.
• Dsruptive: Swedish developer of injectable NFC implants with integrated LEDs (SIID). Direct technology peer and OEM module supplier to Dangerous Things for the xSIID/NExT v2 LED-based implants.

Emerging players

• Flipper Zero: Multi-tool device for RFID, NFC, Sub-GHz, and other protocols, popular with biohackers and security researchers. Comparable to Dangerous Things' Proxmark3 and reader accessories within the maker/hacker tool ecosystem.
