About Us

The whole is greater than the sum of its parts.

It’s how we structure our projects.

It defines who we hire.

It’s the foundation for everything we do.

Part + Sum sits with your team, shares a screen and prepares your business for the new normal.

In a world where reaching customers and developing meaningful relationships is increasingly more challenging, our approach starts with a new way of working.

Inspired by agile software development and paired programming, we believe two heads are better than one. So we pair a member of our team with yours to navigate challenges, tackle projects of all sizes and build lasting capabilities.

That means that our strategies don’t exist in static decks that no one looks at anyway and can be living things that exist in the wild, actual marketing systems, and in the minds of the teams who execute.

That means you have a dedicated partner who can interpret data as it comes in and help you adjust your approach in real time.

That means building sustainable marketing systems and teams that can evolve on their own.

But more than anything, it means you don’t have to go it alone.
