SentientCause Options

SentientCause is the most sophisticated
analysis tool in the market today. As not
everyone will require the full range of tools
that comprise SentientCause, a range of
smaller modules can be chosen to meet
your specific needs (See table 2)

SentientCause can be expanded to include
all or some of the remaining modules as
required by you. The additional modules
provide further diagnosis types that may be
required to resolve more complex

The Payback Period

SentientCause effectively pays for itself.
Our clients experience payback periods
ranging from 6 to 18 months.
