Software built by a team with government experience, for businesses that need it done right.
We design and build web platforms, portals, and internal tools, and we plan for accessibility and security from the start.
Engineering you don't
have to double-check.
Four kinds of work, each planned around the reviews that come after launch.
Web platforms & sites
Fast, well-built websites and web apps that handle real traffic.
Customer & partner portals
Secure portals for customers and partners, with sign-in, role-based permissions, and a full audit trail.
Internal tools & workflow apps
Tools that replace the spreadsheets and email threads your team relies on, including a CMS non-technical staff can update themselves.
Accessibility & security readiness
WCAG audits, fixes, and VPAT support to help your product get through enterprise procurement and lower your legal risk.
Start with a
readiness audit.
We review your site or product against WCAG 2.1 AA and the questions security reviewers usually ask, with the scope agreed up front. You get a conformance report and a prioritized list of fixes, plus a draft VPAT if you sell to enterprises.

our clients work.
Websites and web apps we've designed and built for businesses.

Monsaic
A web app that turns any US-listed stock into a 15-section research report, with each claim linked to SEC filings and earnings calls. Includes accounts, a saved-report library, and paid plans.

Haru Lab Coffee
An online store for a small-batch coffee roaster in Elk Grove, California, with a coffee catalog, subscriptions, wholesale ordering, and customer accounts.

EZM, Inc.
A site for a family-owned organic blueberry farm, built so produce buyers and school districts can find pack sizes, pricing, and certification documents in one place.
A small team that
doesn't cut corners.
Three things you can expect when you work with us.
Built where the bar
is highest.
We learned to build software on government projects. Accessibility is required by law there, security reviews are thorough, and every decision has to be documented. We bring what we learned there to our work with businesses.
We're a small team by choice. When you work with Tessmark, you talk directly to the engineers building your platform, and you always know where the project stands.
We also work with federal agencies and prime contractors.
