THORBJØRN FESSEL
HELLO.
AI Lead & Senior Creative Producer at Uncle Grey, bridging over 15 years of high-end commercial production with cutting-edge advanced GenAI workflows.
I have contributed to virtually all of the agency work showcased at unclegrey.dk.
My foundation is built on deep expertise across the visual and auditory spectrum—spanning professional cinematography, photography, editing, VFX, motion design, music composition, and sound design. This multi-disciplinary mastery allows me to orchestrate complex creative projects with precision and lead the team to deliver high-end competitive work.
While many leverage AI on a surface level, my approach goes lightyears beyond the ordinary user. I possess a unique, technical understanding of AI architecture and custom node-based pipelines, pushing the technology to its limits to build innovative production workflows that seamlessly connect raw creative visions and highly useful custom AI workflows and builds for either clients or internal.
On a personal note, I'm a happy father living in a cozy house in Hvidovre, Copenhagen with my small family of 3 and a big cat.
I enjoy a healthy lifestyle practicing hard CrossFit 2–3 times a week, though I'm not shy for a good burger or a heavy night out once in a while.
I'm a lifelong musician that later became a producer. I'm still producing music to this day—both professionally for clients at Uncle Grey but more importantly for me as an artist. I've written music for everything from huge festival stages to small lowkey short films.
I play the piano and lead guitar, and also played the French Horn for many years back when I was a teen as a member of the Tivoli Boys Guard in the Tivoli Gardens.
I operate as a true hybrid—a seasoned creative powerhouse and a visionary technologist redefining the boundaries of modern visual communication.

AI MASTERY
LIGHTYEARS BEYOND
THE ORDINARY USER.
I build complex, multi-model workflows to extract maximum quality from current technology while building for tomorrow's infrastructure. E.g., I built this site in one day.
Autonomous Systems,
Built for Real Impact.
I develop, train, and deploy MCP (Model Context Protocol) agents as a core part of my daily practice — building pipelines that bring precision, scale, and consistency to complex, repeatable workflows across any discipline.
I lead an AI pilot at Uncle Grey, one of Denmark's leading creative agencies. The project centres on designing a fully autonomous system that integrates with external client servers, internal platforms, templates, and production software — managing the end-to-end production of a client's weekly publication through a carefully orchestrated MCP architecture across multiple LLMs.
Production time that previously spanned multiple days and numerous contributors now runs as a structured, automated pipeline — reliable, repeatable, and consistent. The freed capacity is redirected toward higher-value creative and strategic work, where human judgement actually makes a difference.
Strategy & Prototyping
Setting the right AI strategy by deeply understanding client challenges. Mastering emerging GenAI tools to build functional prototypes that bring concepts to life in pitch rooms and rapidly validate ideas.
Autonomous Agents & Architecture
Engineering hyper-complex ComfyUI pipelines and building advanced autonomous AI agent systems. Orchestrating custom multi-model workflows capable of multi-step decision-making.
Asset Gen & Model Intelligence
Producing high-end film, motion, and still assets. Training proprietary LLMs, fine-tuning LoRAs, and deploying the optimal engine (Claude, GPT, Gemini) for peak output quality and visual precision.
MODEL STACK & CAPABILITIES
GPT, Gemini, Claude (High-end agent construction and full-stack app building).
Veo, Kling, LTX, Sora, Seedance, Omni, Wan (VFX, in-painting, complex motion control). Operated either stand-alone or through complex custom workflows in ComfyUI.
Nano Banana, GPT, Midjourney, Ideogram, Flux, Recraft. Training offline models like LoRAs, weights, and client-specific models integrated into advanced ComfyUI pipeline architectures.
AUDIO EXPERTISE
Music Composition & Production
Scoring evocative soundtracks, acoustic themes, and modern electronic records tailored for global cinematic campaigns and brand narratives.
Audio Engineering
Experienced audio technician for live studio voice-over recording sessions, paired with full audio post-production, mixing, and mastering—delivering broadcast-ready sound for high-end commercial campaigns across all playback systems.
Sound Design & Foley
Crafting custom auditory environments, tactile texture details, and immersive soundscapes that elevate narrative flow and visual depth.
