3xK Tech GmbH was entered in the commercial register at the Frankfurt (Oder) district court on June 7, 2021, assigned registration number HRB 18693 FF. Its founding address was Altenhofer Weg 21 in Schorfheide, a municipality in the Barnim district of Brandenburg north of Berlin.

The company launched with the statutory minimum share capital for a GmbH, EUR 25,000. Its registered business purpose was drafted broadly: internet connection and VPN software and services, plus e-commerce software, leaving room to operate infrastructure services under the connectivity umbrella.

The PlainProxies service launched the same year, entering the commercial proxy market with residential, datacenter, ISP, and IPv6 proxy products. Early differentiation focused on pricing structure: unlimited residential bandwidth plans at a time when competitors billed per gigabyte.

The company registered and began operating its own autonomous systems, AS200373 and AS198571, publishing abuse contact details under the 3xktech.cloud domain. Owning ASNs gives the company direct routing control and peering capability rather than operating purely as a reseller of upstream bandwidth.

A September 2024 shareholder resolution amended the company's articles concerning annual accounts and profit utilization, recorded in the commercial register in October 2025. The filing history shows an active, compliant company.

Through 2025 and 2026 the PlainProxies product expanded its stated coverage to 195-plus countries and more than 25 million residential IPs, adding sticky sessions, high-concurrency threading, and API integration aimed at professional data collection users.

No litigation, regulatory action, or documented controversy involving 3xK Tech GmbH was identified in public records reviewed for this page. The proxy industry broadly faces scrutiny over residential IP sourcing consent, a structural issue the company addresses through its stated compensation model.
