Rilla

rilla.com
Rilla is a SaaS company focused on helping field sales teams perform better by turning real conversations with customers into practical coaching and performance insight. Its product is built around capturing and analysing what happens in the moment, typically during in person visits or on the road, so managers and reps can understand what is being said, what works, and where improvement is needed. The underlying problem it tackles is familiar in field sales, coaching is often inconsistent, feedback is subjective, and it is hard to scale best practice across a dispersed team.
