Qustodio — company profile
Qustodio (Qustodio Technologies SL; US litigation entity Qustodio, LLC) is a Barcelona-based developer of consumer parental-control and digital-wellbeing software, founded in 2012 by Eduardo Cruz, Josep Gaspar and Josh Gabel, with headquarters at Roger de Flor 193, Barcelona. It is not an independent company: it was acquired by Australian-listed Family Zone (later renamed Qoria, formerly ASX: QOR) in 2022 — deal values reported by third-party databases range from ~US$25M to ~US$52M — and Qustodio is now an operating subsidiary within Aura Consolidated Group, Inc. (ASX: AXQ), which completed its acquisition of Qoria on July 17, 2026. Aura reported >US$300M pro forma combined ARR (year ended Dec. 31, 2025). Qustodio's own segment ARR was reported by Qoria at ~US$15.6M with 15–20% YoY growth (Sept. 2024 quarter). Headcount is small, roughly 70–90 employees per company and PitchBook figures; third-party revenue estimates (e.g. ~US$5M–16M) are inconsistent and unverified.
Products / operations. Qustodio sells cross-platform (Windows, macOS, Android, iOS, Kindle) parental-control subscriptions, sold direct-to-consumer in 180+ countries and 9 languages, plus a B2B2C "Community" offering distributed through US K-12 school districts. Core capabilities include screen-time limits and scheduling, web/content filtering, app blocking and usage reporting, activity reports, location tracking, Android call/SMS monitoring, and YouTube and social-network monitoring. Recent feature additions include search alerts, AI-based threat detection, and support for school-issued learning devices.
Patent-litigation posture. Qustodio is an operating company, not an assertion entity. The single tracked case has it exclusively as a defendant (0 plaintiff / 1 defendant), and it is a straight defensible posture: Qustodio was sued, not suing.
Notable case. Kajeet, Inc. v. Qustodio, LLC, No. 8:18-cv-01519 (C.D. Cal., filed Aug. 24, 2018, Judge John A. Kronstadt). Plaintiff Kajeet — an operating wireless/education-connectivity company — asserted patents on rule enforcement for mobile devices (U.S. 8,712,371; 8,630,612; 8,667,559) against Qustodio's parental-control product. Qustodio moved to dismiss on §101/Alice eligibility grounds; the court granted dismissal without prejudice in February 2019, permitting an amended pleading, and the case was voluntarily dismissed with prejudice in February 2020, each side bearing its own costs and fees except those already awarded. Defense counsel has publicly described a dismissal on patent ineligibility plus a fee award on related claims. The case was filed in the Central District of California, not a plaintiff-friendly Texas venue, and Qustodio publicly solicited other startups to join a defensive challenge to the patents.
Stradling LLP reports it defended Qustodio and secured a §101 patent-eligibility dismissal plus attorneys' fees; described as a tool for managing children's use of mobile devices. The narrative does not identify the patent asserted or a case number.
