VikramVisweswaraiah has experience designing and implementing various pricing strategies for telco infrastructure software, including transitioning to subscription models. Some strategies he has used and lessons learned include: implementing tiered pricing to maximize revenue; offering volume discounts to increase deals at higher volumes; bundling features to simplify offerings; and using value pricing models to show customer ROI, though customers don't always accept such models. Metered pricing is effective if the meter matches metrics of value and growth and can be accurately measured. Freemium requires a paid offering to follow, and ELAs work best with large customers if innovation keeps the product valuable.
