Software, and the network it runs on.
Fast Object is an engineering firm in San Diego. We design, build and maintain software for growing businesses, and host it on our own network in Fremont and Los Angeles.
What we do
One team for the whole life of a system: from the first design conversation to the servers it runs on years later.
Software
- Software design
- We turn a business problem into a system you can reason about: the data model, the service boundaries, the interfaces, and a plan to build it in stages.
- Implementation
- Web applications, back-office systems, online stores, APIs and integrations, built by the same engineers who designed them.
- Maintenance
- Upgrades, security patches, monitoring and fixes for software already in production, including systems someone else wrote.
- Consulting
- Architecture reviews, technical due diligence, and a second opinion from senior engineers before you commit to an expensive decision.
Infrastructure
- Hosting and colocation
- Run your applications and servers in our Fremont and Los Angeles sites, on hardware and links we operate ourselves.
- Our own address space
- IPv4 and IPv6 space registered to us with ARIN, so your services keep stable, clean addresses that we control end to end.
- Network engineering
- Design and build of office, campus and wireless networks, from the first survey to a documented handover.
Two sites on the West Coast, one network.
We run our own racks, routers and address space. When something needs attention, the people who built it are the people who fix it.

Fremont, California
Our Northern California site, in the Bay Area.

Los Angeles, California
Our Southern California site, for geographic redundancy and reach.
Address space
Registered with ARIN to Fast Object LLC (org FOL-11) since 2015.

How a project runs
The same four stages whether it is a two-week review or a multi-year system.
Understand
A working session on the problem, the constraints, and what a good outcome looks like. You get a written summary either way.
Design
Architecture, data model and a phased plan with estimates, reviewed with you before any code is written.
Build
Short iterations with working software at every step, deployed to your cloud or to our network.
Run
After launch we monitor, patch and improve what we built, for as long as it is useful to you.

Small on purpose.
Fast Object was founded in San Jose in 2015 and is now based in San Diego. We stay small so that the engineers who design your system are the ones who build it, and the ones who answer when it needs attention.
Most of our clients are online retailers and small to mid-sized companies that need senior engineering without building a large in-house team.
