What differentiates Fathom from other service providers?

According to an independent study, “Fathom is recognized as a trusted, high-complexity provider that is capable of meeting short lead times”. Fathom is highly regarded as a trusted service provider due to our ability to meet specifications on tight timelines, our quick quoting and responsive customer service, and our comprehensive engineering expertise with in-depth support.

Fathom is headquartered in Oakland, CA (offices and production centers) with services offered nationwide. Additional production centers are located in Seattle, WA and China.

Look to a Fathomer to help you make it happen, because no matter how challenging or impossible a design may seem, Fathomers will help you determine what technologies, materials, processes and combination thereof to achieve what you can Fathom—from testing aesthetics, form, fit and function to producing end-use parts like assembly fixtures or finished goods. Fathom encourages companies to focus on how a product should function rather than how it will be made to achieve the greatest product functionality. Whether manufactured traditionally, additively or a hybrid of both, this “outside-in” approach of ours enables companies to realize better products faster and more efficiently.

Does Fathom serve my industry?

Our experts work with a wide range of professionals involved in the product development process and we understand the need for security, confidentiality and for specific certifications. We are ISO 9001:2015 Certified, AS9100 Rev. D Certified, ITAR Registered, and NIST 800-171 Compliant. We regularly serve companies of all sizes across industries such as medical, consumer products, electronics, automotive, aerospace, and sporting goods.
