There is no question at all that there is a return on investment.

There is an ROI when people use the solution. I can't speak to the exact pricing. 

At the end of the day, if a customer is spending such an amount of money, they want to see an ROI. However, small and medium companies, due to the pricing, are less likely to witness any ROI. Enterprise-level organizations will likely see results that are much more impressive. 

We have seen a return on investment, but I cannot speak to the details.

The ROI is very good with this integration platform as is the case with similar iPaaS and API management offerings in the market.

The TCO of an application landscape is heavily reduced by phasing out possible existing middleware, custom point-to-point integration, underlying infrastructure, and reducing technical debt.

Vendor lock-in of existing IT suppliers with possible (legacy) applications and heavy customization can easily be reduced by following the proper implementation approach and by this decoupling Line of Business applications in a landscape. "Legacy modernization" is another use case, that can be realized with the platform.

The API-led approach of MuleSoft offers a very cost-efficient model and re-use for implementation and support of microservices, APIs and (generic) services when followed correctly, and is fully supported and enabled by the web engagement tools of the platform (Anypoint Exchange, Anypoint Portals, and Anypoint Design Center). The approach results in a decrease of maintenance costs and time for internal IT departments and external IT vendors and frees up time in an organization for innovation.
