What we do

Precision-built
for public service.

Three core capabilities, each built to the standards government demands and primes expect from a reliable sub.

01 / Web platforms
Accessible web applications

Public-facing portals and internal agency tools built to USWDS standards. Performant enough to run on restricted government hardware.

02 / Agency portals
Role-based secure portals

Systems that connect agencies, contractors, and citizens. Authentication-ready, compliance-first, built for the audit trail.

03 / Compliance-ready development
Security review from day one

Code that passes review because we've read the spec. FedRAMP-aware architecture, Section 508-compliant by default.

Selected work

Built for the workflows
clients actually run.

Shipped client work across various sectors.

Why Tessmark

Small team.
No shortcuts.

Three things that are true about how we work — and rare in this space.

/ 01We write code that passes security review — because we’ve read the spec.
/ 02We’ve read the USWDS guidelines so your agency doesn’t have to start from scratch.
/ 03Three engineers. Direct access. No account managers between you and the work.
About

Built by people
who understand government.

Government agencies deserve better digital infrastructure. That's not a controversial take — it's why Tessmark exists. We started this firm because we kept watching agencies struggle with platforms that were built without understanding how government actually works: the procurement cycles, the compliance requirements, the accessibility mandates, the security reviews.

We're not a large firm with a government practice. We're a small team that works exclusively in this space — which means every decision we make is grounded in the standards, vocabulary, and constraints of federal and state digital work.

When you work with Tessmark, you're talking directly to the engineers building your platform. No account managers, no translation layer, no surprises at delivery.
