About

Building at the edge —
literally.

El Segundo, California. The aerospace corridor. The place where serious space hardware gets built. That's where Sophia Space is headquartered and where TILE is being engineered.

Founding story

Founded on a hardware problem, not a business trend

Rob DeMillo founded Sophia Space in 2023. The prior years had been spent close to satellite programs — embedded systems development, AIT phases, the hand-offs between payload teams and ground segment. The recurring pattern was the same on every program: operators were building sophisticated sensors, then watching most of the data they collected rot in a downlink queue because the communication link couldn't keep up with the payload.

The question that led to TILE was simple: the satellite already has power. It already has the data. The only thing missing is compute that can operate reliably in the orbital environment — not COTS silicon with a thin radiation narrative, but hardware engineered for TID accumulation over a 3–5 year LEO mission, with SEL protection, ECC memory, and a power draw that fits within the EPS budget of a 6U or larger CubeSat.

We are not building a repurposed cloud compute module. We are not building a ground-station software product that happens to talk to satellites. TILE is purpose-built orbital compute hardware, designed from the start for unattended operation in the radiation environment. That distinction shapes every engineering decision we make.

Sophia Space received angel backing in 2025. We are a small team in El Segundo. We are building something the satellite industry has needed for a long time and has not had done well.

How we operate

Three operating principles

01

Precision

We build hardware that must not fail in an environment where we cannot retrieve it if it does. That constraint drives component selection, radiation test budgets, scrubbing interval design, and what we will and will not claim the product can do at a given development stage. Precision is not a branding decision. It is the design requirement.

02

Transparency

TILE is in development. We will not describe it as flight-proven, in-orbit deployed, or certified to standards we have not completed. Operators evaluating TILE will always know which specs are validated test results and which are design targets still subject to revision as hardware iteration progresses. Hardware trust is built slowly. We're not in a hurry to claim more than we can back.

03

Proximity

El Segundo puts us ten minutes from the engineering offices, machine shops, and test facilities this work requires. More importantly, staying close to satellite operators during TILE's development phase means the hardware gets shaped by real AIT constraints and actual bus integration requirements — not abstracted requirements documents. Hardware built with mission architects in the room fits differently than hardware built for a generalized spec.

El Segundo, CA

In the heart of the aerospace corridor

El Segundo and the South Bay form one of the densest concentrations of aerospace engineering capability in the United States. The region supports satellite prime contractors, smallsat bus manufacturers, propulsion developers, RF and antenna specialists, and electronics manufacturing — all within a short drive. That density matters when you are iterating on hardware.

2120 Park Place puts us adjacent to Aerospace Corporation and within the footprint of what has been Southern California's space industry for more than 60 years. For a team building precision orbital hardware, the engineering decision and the location decision are the same decision.
