Sitrick and Company is handling PR for the co-founders of Blackberry, who may bid for the troubled and restructuring smartphone company.
Blackberry received a $4.7B offer from its largest investor Fairfax Financial Holdings last month.
Mike Lazaridis and Doug Fregin started Blackberry in 1984 as Research in Motion.
Lazaridis is former CEO who stepped down in May from the vice chairman post. Fregin left in 2007 as VP-operations.
They are using Goldman Sachs and Centerview Partners to explore the takeover.
Blackberry's patent trove could be worth as much as $3B.
Samsung, Lenovo, Cisco Systems and SAP are reportedly interesting in acquiring at least parts of Blackberry.
