One vision. Thousands of decisions.

We are building the platform that remembers them all — every draft, character, location and creative call on a film, from the first idea to the final frame. In private development now, from an engineering studio in Los Angeles and Ventura.

Untitled production platform

A single place to develop, plan and shoot a film or series — script, cast, locations, look, and every choice behind them — from the first idea to the final frame.

It starts when you do.

Page one. No crew, no budget, no permission needed. The film exists as a thing you are building — not a folder of drafts named final_v7.

Then the crew arrives.

Same production, more hands. Everyone works from the version that is true today, not the draft from three weeks ago that somebody still has open.

It protects what you meant.

Two hundred people will interpret your film. This is the record of what you actually intended — every choice and the reason behind it, still legible at the last frame.

One writer, or three hundred crew. It is the same film either way.

Security & handling

Unreleased material. Treated like it.

Nobody hands over an unreleased script on a promise. Yours stays yours — kept apart from every other production, seen by nobody else, and gone the moment you say so.

The studio

What we do when we aren't building our own product.

Client work funds the platform and keeps the team sharp. Four practices, one team — in entertainment and outside it.

01

Footage, understood

Software that watches every frame — finding the shot you need, catching what went wrong, reading what's on screen. Faster than a room full of people, and it doesn't get tired at 2am.

02

Answers from your own material

Ask a question, get an answer drawn from your own documents and archives, with the source attached. We measure whether it's right, so you don't have to take its word for it.

03

Built to keep running

The unglamorous half: making sure it stays up, stays fast and doesn't get more expensive every month as you use it more.

04

Games and interactive

Mobile titles built and tuned while they're live. Ten million downloads to date.

Engagements start with a scoping call and a number we agree to move. Most first systems are running inside four weeks.

Shipped, and still running.

Client names on request. Figures measured in production over rolling windows, not at launch week.

Footage QC for broadcast

A review desk that used to be people watching everything, replaced by software that flags only what a human needs to see. The direct ancestor of what we are building now.

Viral game engine

The system behind a mobile title with ten million downloads — tuned week by week while players were in it, rather than shipped once and left alone.

Ten years of tickets and manuals made answerable in a sentence, with the source attached so the team can check it.

Who we are

Sigma. The sum of every decision.

The name is the mark. Sum AI — Σ — because a film is the sum of everything everyone decided, and we build the thing that keeps count.

Sum AI is a small engineering studio in Los Angeles and Ventura. We stay close to the data, blunt about what this technology can and cannot do, and allergic to demos that quietly fall apart at real volume.

Because the team is small, the people who scope your project are the people who write the code and carry the pager. Twenty systems shipped across eight industries, and every one of them still running.

Contact

Two ways in.

We reply within one business day, and the first call is a conversation about your work — not a pitch.

For writers, directors & producers

Ask about the platform

We will walk you through what it does, under NDA, and tell you honestly whether your production is a fit for the beta.

For anyone with something to build

Start a project

Hire the studio directly — for something you need built, or something you need built better. Scoping call first, then a number we agree to move.
