How to Sustainably Grow a Creative Agency with Humble Experts and Utilization Spreadsheets

Gray MacKenzie is joined by Arianne Foulks, CEO and founder of Aeolidia, a creative ecommerce agency that has been in business for over 20 years. Aeolidia specializes in working with creative product founders - jewelry, bath and body, stationery, home goods, kids toys, and clothing brands - providing Shopify design and development, brand identity, brand strategy, and email marketing through Klaviyo. With approximately 20 team members including contractors, Arianne offers a masterclass in building a creative agency that grows steadily without sacrificing quality or culture.

Sustainable Growth Over Two Decades

Arianne’s approach to growth stands in contrast to the common agency playbook of scaling as fast as possible. Aeolidia has grown slowly and deliberately over 20-plus years, transitioning from a solo operation to a 20-person team at a pace that kept the quality of work and client relationships intact. Arianne is candid that she prefers a smaller operation where she can maintain personal connection with every team member.

This philosophy extends to how the agency evaluates opportunities. Aeolidia does not pursue growth for its own sake. Every project, service expansion, and hire is evaluated against whether it genuinely serves clients or strengthens the company. The recent expansion into email marketing through Klaviyo is a good example - it was a natural extension of the storytelling work Aeolidia already does through website design, not a random pivot into an unrelated service.

The Humble Experts Culture

One of Aeolidia’s defining characteristics is the concept of “humble experts.” This is a core value that shapes hiring, collaboration, and day-to-day interactions. The idea is straightforward - team members should be confident in their expertise while keeping ego completely out of the workplace. They know they are good at what they do, but that confidence does not translate into defensiveness, blame-shifting, or resistance to feedback.

Arianne describes her hiring approach as deliberately minimal on micromanagement. She prefers to drop new team members “in the deep end” and see how they perform with autonomy. Successful hires demonstrate openness to learning, shared responsibility for outcomes, and a natural inclination toward collaboration rather than self-promotion. This approach builds a team of self-directed professionals who do not need constant oversight to deliver excellent work.

Data-Driven Decisions with Utilization Spreadsheets

One of the most practical takeaways from the conversation is how Aeolidia uses utilization spreadsheets to drive strategic decisions. Project manager Melissa developed two spreadsheets using data from ClickUp that track both team utilization rates and per-client profitability.

These spreadsheets allow the team to forecast availability, compare billable versus internal work time, analyze which projects and project types are most profitable, and identify areas where pricing may need adjustment. The data feeds directly into quarterly strategic reviews where the leadership team makes decisions about which services to expand, which to scale back, and where pricing changes are needed.

This approach removes guesswork from some of the most consequential decisions an agency makes. Instead of relying on gut feel about which clients or services are profitable, the team has clear numbers that tell the story. Arianne notes that this was a significant mindset shift - she was initially skeptical about how much of their creative work could be reduced to processes and metrics, but the results changed her perspective entirely.

Lessons from the Long Game

Arianne draws business inspiration from “Profit First” and “Clockwork” by Mike Michalowicz, along with “4000 Weeks” by Oliver Burkeman. From “Clockwork,” she adopted a compelling benchmark - the organization should be strong enough that any member of the leadership team can take a four-week vacation without disruption. This standard forces you to build real systems and develop team members who can operate independently.

The post-pandemic period tested many agencies, and Aeolidia’s sustainable approach paid off. By not over-extending during boom times, the agency was positioned to weather uncertainty without dramatic cuts or pivots. Arianne credits this resilience to the deliberate choices made over two decades of building slowly, hiring carefully, and staying focused on what the agency does best.
