Gyda'i gilydd mae Buddsoddi i Arbed ac Arloesi i Arbed yn rhoi i sefydliadau ddewis gwirioneddol o ddewisiadau ariannu ar gyfer eu cynigion. Mae cyrff sydd â syniadau sydd yn nyddiau cyntaf eu datblygiad lle mae angen ymchwil i weld pa mor hyfyw ydynt, yn gallu gwneud cais i'r Gronfa Buddsoddi i Arbed am gymorth; mae prosiectau sy'n barod i gael eu cyflwyno yn gymwys am y Gronfa Buddsoddi i Arbed.
Together, Invest to Save and Innovate to Save provide organisations with a real choice of funding options for  their proposals. Organisations with ideas, which are at the very early stages of development and need research to establish their viability, are able to apply to the Innovate to Save fund for support; projects which are ready to be rolled out are eligible for the Invest to Save fund.
