As a SaaS company, you might want to display multiple call-to-action buttons on your landing page. Most of the time, you will have a primary CTA dedicated to prospects ready to convert ("Get started", "Try now"...) and a secondary CTA for hesitating visitors ("Get a demo", "Learn more"...).
Make sure to create a visual hierarchy to make the focus on the most import CTA. This can be done by using a predominant color for the primary CTA and a less noticeable color for the secondary.
This concept also applies to CTA buttons that come in a pair ("Login" & "Signup", "Confirm" & "Cancel"...)
