Commercial Software

In addition to building custom software, we make and sell:


RetroacDev helps software companies claim the Research and Development Tax Credit.

Plug it into your GitHub or Bitbucket account, and RetroacDev constructs time estimates for how much time each software engineer spent on each project. Then it walks you through questions to determine how much of each project counts as Qualified Research.

We built it for our own use, and the first year we used RetroacDev, it got Zagaran over $10,000 in tax credits.

Instant Census

Instant Census is a platform for sending automated text message surveys.

Customer service-focused companies use Instant Census to ask quick feedback surveys.

Academic researchers use Instant Census for diary studies (questions every few hours), long-term unintrusive studies, and connecting with difficult-to-reach populations like migrant farmworkers.

Open Source Software

Beiwe Research Platform

Zagaran built, maintains, and supports Beiwe, a research platform administered by the Harvard T. H. Chan School of Public Health. The Beiwe platform combines a researcher web dashboard with Beiwe's HIPAA-compliant, fully encrypted smartphone application (Android/iOS) to give researchers the ability ato deploy health surveys and track the activity of participants using smartphone sensors. Beiwe runs over 100+ medical studies for research groups at hospitals and universities around the world.

Open Source Libraries

Our work relies on open source software, and we do what we can to contribute back to the open source community. These are some of the projects we've created and maintain:

Sample Django App

Sample Django App is a fully runnable Django application, along with valid configuration for a number of helpful addons. This is intended to be a reference for both new and existing Django projects.
