3Si2

3Si2 specializes in legacy system integration, software engineering and development with a range of IT services to various sector markets. Put simply, it is about building software for you when nothing off the shelf fits.

Who is it for? Mostly companies with a specific process to automate. Alongside the main category they mention Software Engineering. As a small company team themselves (11 to 50 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

3Si2 is based in Carlsbad, California. You can read more at 3si2.com.

Before you commit, look at portfolio relevance, who owns the code, and how they handle changes. Ask for a trial on your own data, not a canned demo.
