| Plumbr | Plumbr makes Java applications faster and more reliable.It builds upon world class algorithms (patent pending) and crowd sourced knowledge base to effectively verify that your Java Java application does not have performance bottlenecks. It understands the architecture of the monitored application and interprets metrics in the context of thatapplication.Should the application have performance threats, Plumbr's unique approach traces the reasons down to source code or environment configuration and creates human readable detailed instructions that help engineers solve the problems fast. Without Plumbr, such problems typically take weeks of engineering effort to understand and fix. | $1M | Seed | Nov 12, 2013 |  |
