About SullySoft

SullySoft was built to give growing businesses access to senior technology, cybersecurity, software engineering, and automation expertise without the overhead of a large consulting firm or full-time executive hire.

Founded by Mike Sullivan, SullySoft brings more than 25 years of hands-on experience across software engineering, enterprise architecture, DevOps, cloud security, automation, and cybersecurity. That background allows SullySoft to help clients solve practical technology problems while keeping security, maintainability, and long-term reliability in focus.

Who We Work With

Best Fit Clients

SullySoft works best with organizations that need practical, senior-level technology expertise but may not have the internal team, time, or budget to handle everything themselves.

Our clients are often growing businesses, startups, founders, and lean teams that need help making smart technology decisions, improving security, automating operations, or building software without taking on unnecessary complexity.

SullySoft typically works with:
