SirenOpt

SirenOpt provides manufacturing intelligence solutions for nanoscale materials used in semiconductors, electronics, batteries, and aerospace. Put simply, it is about solving a specific business problem with software.

Who is it for? Mostly teams in its space. Related areas on their profile: Aerospace, Battery, Electronics, Manufacturing and Semiconductor. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

SirenOpt is based in Oakland, California. More on sirenopt.com.

Things worth asking about: pricing, support, and how it fits with the tools you already use. Get the renewal terms in writing before the first invoice.

If you have worked with SirenOpt, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
