Aberdeen-based Inoapps, a leading supplier of Oracle software and systems support, has picked up £10 million from the Business Growth Fund which is backed by the main high street banks.
Meanwhile, Edinburgh's Sumerian has received £2.4 million from Scottish Equity Partners (SEP) and Scottish Enterprise's Scottish Investment Bank (SIB) to support the launch of a software platform.
BGF has taken a minority stake in Inoapps, which was founded by chief executive Andy Bird in 2006.
The fund will now work with Inoapps to find a chairman with industry experience to oversee the next stage of its growth.
Inoapps provides consulting, implementation and hosting for Oracle applications and hardware.
After doubling turnover in each of the last two years, its income amounted to £20m in its last financial year to July.
BGF investment director Mike Sibson who will be joining Inoapps board, said: "It (Inoapps) is on a highly impressive growth trajectory, driven by consistent, high quality project delivery."
Sumerian, for its part, is preparing to launch its new Sumerian Workbench, which is intended to allow companies to identify cost savings and performance gains on their information technology estates.
SEP partner Andrew Davison, who led the deal, said: "Our further investment in Sumerian is based on growing global market demand for its IT analytics services and an impressive list of blue chip clients."
Head of SIB Kerry Sharp said: "Sumerian illustrates Scotland's worldwide reputation for innovation, performing advanced analytics that deliver tangible business value to the customers they work with."
