Contract Manufacturer Comparison
Fathom vs. Jabil
Not every program needs a $29.8B global EMS provider. Most defense programs need speed, flexibility, and domestic control at low-to-mid volume, which is the gap that Fathom fills.

Choosing The Right Contract Manufacturer
| Criteria | Fathom | Jabil |
|---|---|---|
| Ideal customer type | FathomMid-market and enterprise programs | JabilAverage revenue per customer: $75M |
| Ideal order type | FathomPrototype, bridge, low-mid volume production, second-sourcing a domestic supply line | JabilSustained high-volume programs |
| Ideal order quantity | FathomUp to 25,000 units | Jabil20,000–1,000,000+ |
| Manufacturing technologies offered | Fathom30+ in-house technologies, including CNC, EDM, sheet metal, additive manufacturing and photochemical machining | Jabil7 published capability areas: automation, electronics, large form factor assembly, metals, optics, photonics and plastics |
| Manufacturing location | Fathom100% U.S.-based production across 7 U.S. locations | Jabil100+ sites across 25+ countries; optimized for global cost and scale. |
| Design change flexibility | FathomBuilt for iteration. Engineering changes mid-program are routine. | JabilLate-stage design churn is expensive by design. |
| Engineering engagement model | FathomEvery quote reviewed by an engineer up front. DFM included. Dedicated project expert from concept through production. | JabilEngineering engagement typically begins once a program clears a volume and revenue threshold. |
| Defense-relevant certifications | FathomAS9100D, ISO 9001:2015, ITAR registered, NIST 800-171 (certifications vary by location). | JabilHolds relevant aerospace and defense certifications across its defense-focused sites; scope and location vary by facility. |
| Best fit for | FathomPrototyping, high-mix low-volume production, complex geometries in exotic materials, quick-turn spares. | JabilMature, high-volume, stable-design programs where unit cost dominates and the design is frozen. |
The Core Argument
Jabil is the right answer when your design is frozen and you need a million of them. Fathom is the right answer for everything before that, and for the 80% of defense programs that never reach a million units at all.
