Hi!

I’m TJ Marriott.

As the Sr. Client Engagement Lead at Part and Sum, I am your main point of contact for projects with our team. I ensure that our team delivers on the scope you signed up for. You can think of me as the connective tissue between you (the client) and our internal teams. I help translate the work we are doing together to any person or team you work with. Lastly, I am your solution architect across all of our products and services to help guide our partnership to achieving your company goals and KPIs.
About TJ Marriott

Over the course of seven years, TJ has worked with ecommerce, subscription, retail and service based companies from the enterprise level down to startups. He applies a strategic, data driven approach to profitably grow new customer acquisition, reduce churn and grow market share for his clients.

Some of TJ’s achievements include driving the first year of profitable growth in over a decade for a centuries old clothing brand and beating the first year revenue target by 2x for a legacy client launching a new product vertical.
Here at Part and Sum we bolt on to transform digital experiences and grow brands by seeing through the eyes of your customer.
TJ’s POV on seeing through the eyes of your customer:
“Seeing through the eyes of your customer unlocks growth, efficiency and customer stickiness. Being able to empathize with whoever your customer is, enables brands to build effective messaging and distribute it in the right place at the right time to convert a new customer or trigger a repeat purchase.”
