How Ecommerce AI Is Changing Shopify Growth and Marketing Strategy

“How do you not become obsolete?”

That question sits at the center of modern ecommerce.

In this episode of the Rebellious Times Podcast, I sit down with Mike Brennan, Co-Founder of Developer Squad and Founder of Milexi, to explore how ecommerce AI is reshaping how brands grow, optimize, and compete.

This is the second episode in the Agency Spotlight Series, where we learn from operators building service businesses in a rapidly evolving landscape.

From Social Media to Ecommerce Infrastructure

Mike’s journey began during the early days of social media. At the time, the pace of innovation was exciting and unpredictable.

However, things changed quickly. During the 2008 financial crisis, Mike co-founded Developer Squad. This period forced a more disciplined approach to building a business.

Since then, the landscape has evolved again. Today, Mike focuses on ecommerce and AI through Milexi. As a result, his perspective reflects multiple waves of technological change.

AI Is Reshaping Ecommerce

AI is no longer optional. Instead, it is becoming a core part of ecommerce operations.

For example, AI is already improving:

Product discovery
Personalization
Marketing automation
Customer experience

Because of this, brands must act quickly. Otherwise, they risk falling behind competitors who are moving faster.

The Shopify Ecosystem Is Evolving

Shopify continues to be a strong foundation for ecommerce brands. However, the ecosystem around it is evolving.

Today, there are more tools, more integrations, and more choices than ever before. As a result, complexity has increased.

To succeed in this environment, brands need:

Clear positioning
Strong technical execution
A clear understanding of how tools work together

In other words, it is not about using more tools. Instead, it is about using the right tools effectively.

Beyond ROAS: Understanding Real Profitability

Many ecommerce brands focus heavily on ROAS. However, this can be misleading.

Instead, Mike emphasizes a broader view of performance. For example, brands should focus on:

→ Contribution margin
→ True profitability
→ Conversion rate optimization

Because of this, decision-making becomes more accurate. As a result, brands can grow sustainably rather than chasing vanity metrics.

The Future: Autonomous Agents and OpenClaw

Looking ahead, AI will continue to evolve. In particular, tools like OpenClaw point toward a new model.

In this model:

AI agents perform tasks autonomously
Decision-making becomes faster
Operations become more efficient

Although this may sound futuristic, it is already beginning to happen. Therefore, businesses should start preparing now.
