Q&A search engine ChaCha has just announced it has raised an additional $3 million in supplemental funding from new investor Qualcomm Ventures.
The self-described "human search engine" has now raised a grand total of $75 million through five rounds of funding. They most recently raised $20 million in a Series F led by Rho Ventures and VantagePoint.
Launched in 2006, ChaCha helps users get answers to their questions through independent contractors who answer questions in real time, helping build the service's database. The service also offers SMS and voice search, which is probably the main reason Qualcomm invested in ChaCha in the first place.
Having a strong mobile Q&A platform could be useful to Qualcomm as both companies expand their worldwide wireless efforts. It may also be an indication of acquisition interest by the wireless giant.
