G&L Geißendörfer & Leschinsky GmbH

What G&L Geißendörfer & Leschinsky GmbH does

G&L Geißendörfer & Leschinsky GmbH (operating as G&L Systemhaus) is a Cologne-headquartered managed service provider and systems integrator specializing in the delivery of live and on-demand audio and video content over the public Internet. Founded in 1998 by Hans W. Geißendörfer and Alexander Leschinsky in the context of the German television series 'Lindenstraße,' the company serves German and European public broadcasters (ARD member stations, ZDF, Deutsche Welle, SWR, KiKA, ARTE), government and parliamentary institutions (European Parliament, Landtag NRW, municipal councils in Potsdam and Monheim am Rhein), and selected enterprise customers including Deutsche Telekom, BMW, CERN and Bayer 04 Leverkusen.

The technical stack centers on multi-CDN orchestration (anchored by an Akamai Elite-tier partnership giving access to 4,100+ POPs), hybrid cloud/on-premise deployments constrained to EU data centers in Frankfurt and Düsseldorf, and a proprietary Audio Video Processing Unit (AVPU) that combines Ampere Altra Max ARM CPUs with up to ten NETINT Quadra T1U VPUs to deliver hardware-accelerated H.264/HEVC encoding at 2-3x the energy efficiency of CPU-only workflows. The G&L Playout Hub provides triple-layer redundancy from ingest through encode to egress with multi-tenant deployment in minutes, while the AI-driven G&L LiveCaptions service and integrated Signapse-powered Digital Signer add accessibility features (live subtitles, German Sign Language avatars). The company is ISO 27001 certified since 2024 and is contributing co-author to the SVTA2128 specification for end-to-end quality signaling (CMSD-MQA).

G&L monetizes through a mix of recurring managed services (CDN and streaming operations under SLAs, 24/7 NOC support), professional services (consulting, integration, configuration, custom software), subscription/SaaS rental of hardware platforms such as the AVPU and Playout Hub on monthly to multi-year cycles, and discrete hardware sales. Customer contracts are quote-based, multi-year, and dominated by a small number of large anchor relationships in regulated industries, with go-to-market executed via direct enterprise field sales and partner co-selling through Akamai, AWS, Azure, Google Cloud, Bitmovin, Norsk and others. The firm operates from Cologne (headquarters), Berlin, Munich, and Pleasanton, CA, with field presence across the DACH region, France, the UK, the Netherlands, Belgium, Switzerland and Austria.
