We work with your team.

Most organizations do not have the computing power, the available technical expertise or the time to develop and manage conversational AI and multi-experiences themselves.  

Through a Lunch & Learn session or a strategic planning consulting project, we can introduce voice technology to your team so they can decide when it's time for your organization to get started with voice assistant technology. 

We work with brands who innovate.

Whether you have an in-house brand management organization or an agency of record who provides your digital marketing technology, the team at Whetstone Technologies can participate in your innovation - from consulting about voice technology for strategic marketing integration to designing, developing and hosting voice apps - we're flexible to accommodate your needs.

Digital agency?  Ask us about white-labeling the SoniBridge platform for your organization.

We work with Marketing & IT teams.

Go from pilot to integrated marketing, letting the SoniBridge platform manage the life cycle of your voice apps in conjunction with your customer engagement plan.

We work with the best in the  industry.

We have developed alliances with strategic partners in the rapidly evolving conversational AI multi-experience space.  We conduct due diligence to ensure they can be a viable project-specific or long-term partner in helping our clients achieve their voice technology goals.  

Also, we work with complementary technology partners who provide additional functionality and support.

Most importantly, we are a partner.  The standards we expect of others are those we offer to our strategic partners.

Are you a voice technology pro or a certified cloud developer / architect?  Interested in working with us on a project?
