One company. Story, systems, and mission
Three products.One score.
5th Symphony is the company behind Studio Ultra, Nucleus, and SpaceXen. A production house, a film operating system, and a mission-assurance platform — conducted by Stephen O'Hearn and Ken Greenwood.
Studio Ultra makes the pictures. Nucleus runs the production. SpaceXen refuses a false green.
Write to the houseMovements I–III
A studio. An instrument. A conscience.
The products are distinct on purpose. They share one company, two principals, and a refusal to treat missing evidence as progress — whether the work is a picture or a mission.
Studio Ultra
The production product of the house. Studio Ultra exists to develop and produce original film and series work — the stories Nucleus is built to carry.
Original productionNucleus
A data-driven production cockpit for film and media. Nucleus keeps script, scene, character, location, budget, and crew on one graph — so the studio can see the work as a living system.
Film production operating systemSpaceXen
A mission-risk digital twin for commanders and enterprise mission owners. SpaceXen answers one question with evidence: can we accomplish the mission?
Mission assurance, operationalizedWhy this name
Not a brand metaphor. A working method.
Distinct movements
Beethoven's Fifth is one work in four parts. Studio Ultra, Nucleus, and SpaceXen stay themselves. The company keeps the tempo, not the craft.
A motif, not a slogan
Short, short, short, long. Fate, work, evidence, release. The same four beats show up in a production graph and in a mission thread.
Two conductors
O'Hearn brings Space Command mission assurance and a screenwriter's ear. Greenwood brings enterprise systems, studio craft, and the tools the work runs on.
Principals
Stephen O'Hearn and Ken Greenwood.
Mission and story. Systems and studio. The house is theirs together.

Stephen O'Hearn
Combat veteran, screenwriter, and founder of StoryXen. He spent years in Space Command mission assurance, then turned that same systems discipline toward film production.
