Castlabs

What Castlabs does

Castlabs GmbH is a private Berlin-headquartered software and cloud services company founded in 2007 that supplies digital rights management, forensic watermarking, video player SDKs, and cloud-based media workflow tools to OTT streaming services, PayTV broadcasters, studios, and media production companies. Its product platform centers on three core offerings: DRMtoday, a cloud multi-DRM licensing service supporting PlayReady, Widevine, and FairPlay along with Widevine CAS for IPTV multicast and hybrid PayTV deployments; STARDUSTmark, a single-frame forensic watermarking technology for content leak tracking, including a proprietary capability for frame-accurate watermarking of proxy media files; and PRESTOplay, a cross-platform video player SDK supporting web, mobile, Smart TV, and streaming devices, including a React Native variant developed with 3SS. Supporting products include Video Toolkit (cloud encoding with zero-trust security), PrestoAds (ad tracking and measurement), Offline DRM, WebRTC DRM, and Widevine certification services including Widevine Third-Party Lab (3PL) certification. The company also offers expert engineering consulting for custom integration work.

Castlabs generates revenue through a mix of recurring cloud subscription (DRMtoday, STARDUSTmark), SDK and per-seat/per-view licensing (PRESTOplay), usage-based pricing (Video Toolkit cloud encoding, consumption-based DRM license requests), and professional services. Pricing is not publicly disclosed but entry-point free trials (30-day, usage-capped) support a product-led growth motion alongside direct enterprise sales and integration partner channels (Backlight Iconik, 3SS 3Ready, Unified Streaming, Avid Media Composer). Castlabs is incorporated as Castlabs GmbH in Germany with a US subsidiary (Castlabs Inc. in Burbank) and additional offices in Buenos Aires, Caracas, Quito, and Santiago, and reports GDPR-compliant data processing. The company has not disclosed external venture capital or private equity funding rounds in the available data and offers virtual stock options to employees as its disclosed equity participation mechanism.
