Inside Enterprise Sales: Meet Sierra St John, Lead Client Account Manager

Sierra St John didn't take the straightforward route to Pinterest, and she wouldn't have it any other way. Before landing on the Sales team as a client account manager, she built her foundation as a data analyst. In this conversation, Sierra opens up about what drew her to the role, the people who've helped her grow and what it feels like to be part of the Pinterest Sales culture.

Your background in data science/analytics is unique. How did that prepare you for your role as a Lead Client Account Manager at Pinterest? 

My path to get here wasn't linear! Previous to Pinterest, I completed a data science bootcamp and transitioned into a data analyst role at a major broadcaster, where I spent my days deep in SQL, building dashboards and pulling insights out of billions of rows of data. I loved the rigor of it, but I realized pretty quickly that I wasn't fully built for living in the code alone. I missed the storytelling. I missed being in the room when the decisions got made, translating what the data was saying into something a business team could actually act on.

That's what's made client account management at Pinterest feel like the right fit. My clients in Financial Services (FinServ) don't just want a dashboard, they want to know what to do next quarter. My analytics background means I can sit in a measurement conversation, understand what's actually being asked, and come back with a recommendation that's grounded in the math. It also makes me a better partner to our internal product and measurement teams, I can speak their language, which means I can advocate harder for what my clients need.

What energizes you most about your role? 

Solving complex measurement problems. The kind where a client is trying to understand incrementality, or how Pinterest fits into a media mix model, and the answer isn't obvious. I love that puzzle. What I've learned is that being genuinely inquisitive about the data is what earns you a seat at the table with your partners. When you're the person asking the sharper questions (and bringing back answers their finance team would respect), clients start treating you like a strategic partner instead of just a seller. That shift is when the work feels most meaningful to me!

What has growth been like at Pinterest, and how has your manager supported, or even helped accelerate, your development? 

Honestly, a huge part of my growth here comes down to my manager. Over the past year, she's been one of the biggest advocates I've ever had in my career. She noticed my skills in measurement and data analytics early on and went beyond simply acknowledging my work. She actively championed my growth and development at Pinterest. 

What I've learned from working with her is that growth at a company like this isn't just about hitting your numbers - it's about having someone who sees the full picture of what you bring. I feel really lucky to have that!

Describe the culture of the Sales team. What does it mean to be a part of the team?

The FinServ team specifically is full of people who take the work seriously without taking themselves too seriously, which is a balance I've come to really value. Financial Services is a category where the standards are really high; clients are sophisticated, the measurement bar is rigorous, and the creative has to clear a lot of compliance, so we've had to be sharp. 

What that's built is a team that actually trades notes, shares frameworks, and roots for each other's wins. Being part of it means you're expected to bring something to the table: a point of view, a piece of analysis, a new angle - and you can count on your teammates to do the same.

How are you using Pinterest to find inspiration? 

Mostly for personal style. I do a lot (embarrassing amount!!) of shopping for clothing through Pinterest. It's where I figure out what I actually want before I go looking for it anywhere else. I have a pretty defined sense of my own aesthetic at this point, and Pinterest is where I pressure-test new pieces against it. Saving, comparing, seeing the same silhouette across different price points: it's how I avoid buying things I'll regret. It's also funny being on the platform as both a user and someone who sells it... I'll catch myself mid-scroll noticing an ad and thinking oh, that's smart creative.
