<p>Revolution Ventures&nbsp;announced a $5 million investment in San Diego-based&nbsp;eSUB Construction Software. eSUB is a construction tech startup that offers a software platform for subcontractors to help manage projects, essentially digitizing what is normally a paperwork-intensive industry.</p> <p>&quot;There are always changes to a project as soon as it starts. The problem is when those changes happen paper documents don&#39;t change,&quot; Revolution partner Bobby Ocampo told DC Inno in an interview. &quot;Digitizing it protects subcontractors when there&#39;s a dispute or an audit or if it goes to court. Kind of like an insurance policy for subcontractors.&quot;</p>
