Custom application development
Web apps, installable progressive web apps, and the APIs behind them, built on proven, well-supported stacks like Angular, Node.js, and MongoDB.
Software development & hosting
We build software that works, and we keep it running.
Particle 64 is a small engineering partnership that designs, develops, and hosts custom applications. You work directly with the people who write your code and look after your servers.
What we do
From the first idea to production, and every day after
One team handles the whole lifecycle, so nothing gets lost between the developers and the people running your servers.
Managed hosting & DevOps
Deployment, monitoring, backups, SSL, and updates. We run your application in production and are on call when it matters.
Data, GIS & mapping
Large dataset imports, geocoding, interactive maps, and analytics pipelines that turn raw records into decisions.
Telephony & messaging
In-browser calling, SMS campaigns, hotlines, and compliant A2P 10DLC messaging with Twilio and SignalWire.
Secure accounts & integrations
OAuth and Google sign-in, role-based permissions, payment and third-party APIs, connected securely.
Modernization & rescue
We upgrade aging codebases, fix performance and security problems, and take over projects that others left unfinished.
Proven in production
We build and host Amplify
Our flagship product is a full civic engagement platform that we wrote, maintain, and operate end to end.
Amplify: campaign software that wins
Phone banking, texting, door-to-door canvassing, voter data, mapping and turf cutting, petitions, and hotlines in one app, used by organizers on phones, tablets, and desktops.

How we work
A clear process with no surprises
Discover
We learn your goals, users, and constraints, then agree on a scope and budget in plain language.
Build
We ship working software early and often, so you can see progress and steer as you go.
Launch
We take care of deployment, data migration, and training so your team is ready on day one.
Host & support
We keep your app secure, fast, and up to date, and you can always reach a real engineer.
Who we are
A partnership of hands-on engineers
Particle 64 is deliberately small. The partners who scope your project are the same people who build it, deploy it, and answer the phone when you call.
Direct access
No account managers or ticket queues between you and the people doing the work.
Accountable for production
Because we host what we build, we have every reason to build it right the first time.
Long-term partners
We've worked with the same organizations through several election cycles, and we plan to keep doing so.
