Existing investors Storm Ventures, Sierra Ventures and Relay Ventures also took part in the Series D round.
Appcelerator says its platform enables companies to build, analyse and connect suites of mobile apps “rapidly and efficiently”.
The business has attracted 125 new customers in the past year including Avis and Comerica Bank.
Appcelerator said it will use the funding to increase growth and accelerate adoption of its technology.
Rembrandt managing partner Douglas Schrier said, “The choice for us to invest in Appcelerator was clear; no other company has such a complete set of capabilities to enable enterprises to build and scale a mobility program.
“Many successful brands already trust Appcelerator to power company-wide mobile app initiatives and, as more and more companies put mobile at the top of the corporate agenda, there is tremendous opportunity for Appcelerator to lead the way forward.
Appcelerator has the vision, passion and team to power a mobile-first approach for any organisation.”
Rembrandt took part in a $19m financing round for customer relationship management (CRM) business InsideView in August last year.
