The necessary presence
in government digital.
We build compliant, accessible digital platforms for federal agencies and the prime contractors who serve them.
Built for
government work.
Three things we do well, built to the standards agencies require and primes expect from a subcontractor.
Accessible web applications
Public-facing portals and internal agency tools built to USWDS standards, and fast enough to run well on locked-down government machines.
Role-based secure portals
Portals that connect agencies, contractors, and the public, with secure sign-in, role-based access, and a full audit trail.
Security review from the start
Code written to the security controls it has to satisfy, on FedRAMP-aware architecture that conforms to Section 508 by default.
Built around the way
our clients work.
Client projects we've shipped.

Real-Time Retail Crime Reporting App
A React Native app that lets witnesses send photo and video evidence to a regional law enforcement task force in three taps. We shipped it to iOS and Android at the same time for a county-wide retail theft program.

Statewide Career Services Platform
A career services web portal that works like a virtual counselor. Each student has one account that holds their Career Action Plan, résumé, master job application, search letters, and online portfolio. Counselors update career paths and page content through a CMS, without needing engineers.
A small team that
doesn't cut corners.
Three things you can expect when you work with us.
Built by people
who understand government.
Government agencies deserve better software, and that's why we started Tessmark. We kept seeing agencies struggle with platforms built by people who didn't understand how government works: procurement cycles, compliance requirements, accessibility mandates, and security reviews.
We're a small team, not a large firm with a government practice on the side. Our work starts from the standards, terminology, and constraints of federal and state projects.
When you work with Tessmark, you talk directly to the engineers building your platform, and you always know where the project stands.
Let's talk about
what you need.
If you're a prime looking for a subcontractor or an agency evaluating vendors, get in touch. One of our engineers will get back to you.
