Question 2

Do I need a brief or RFP to get started?

Accepted Answer

Not at all. Some clients come to us with a detailed brief, others with a spark of an idea. We're happy to start wherever you are and help shape the right approach together.

Question 3

How much does working with Part and Sum cost?

Accepted Answer

Every engagement is scoped to fit your goals, timeline, and budget. We'll talk through what you're trying to accomplish and recommend an approach that makes sense—no cookie-cutter packages.

Question 4

What size companies do you typically work with?

Accepted Answer

We work with growth-stage startups, mid-market brands, and enterprise teams at companies like GitHub, Starbucks, and Cash App. What matters most isn't size—it's ambition and a willingness to grow smarter.

Question 5

Can we start with a small project first?

Accepted Answer

Absolutely. Many of our longest partnerships started with a focused engagement—a media test, a research sprint, or a strategy workshop. It's a great way to see how we work together before scaling up.
