Interview

1. Can you briefly introduce yourself and share your journey to becoming the founder of eCommerce Today?

I’m Stefan Chiriacescu, founder of eCommerce Today. I launched the agency in 2019 with a mission to help global DTC brands scale efficiently. Today, we operate as an elite execution hub from Romania, managing growth and technical operations for more than 90 active brands across North America, the UK, and Europe. 

2. What inspired you to start eCommerce Today, and what problem were you aiming to solve?

I wanted to eliminate what I call the “fragmented agency trap.” Many brands work with separate Shopify developers, PPC agencies, and email freelancers who rarely collaborate effectively. This often results in disconnected strategies and missed growth opportunities.

We solved this challenge by introducing a fractional eCommerce department model that provides brands with one coordinated team under a predictable monthly retainer.

3. What is the vision behind eCommerce Today, and how has it evolved?

Our vision has always been to replace disconnected teams with a unified execution engine. We initially focused on Shopify implementation projects but gradually evolved into a full Managed Services ecosystem.

Today, we believe sustainable eCommerce growth comes from continuously combining custom technical development with lifecycle marketing instead of treating growth as a one-time project.

4. What has been your biggest entrepreneurial challenge?

One of our biggest challenges has been balancing reactive technical support with proactive growth initiatives while scaling a team of more than 30 specialists.

The biggest lesson I’ve learned is that clear documentation, structured workflows, and strong operational systems consistently outperform relying solely on individual talent.

5. How do you see AI and automation transforming eCommerce?

AI dramatically increases execution speed.

We’re investing heavily in automated lifecycle marketing through Klaviyo while also focusing on Generative Engine Optimization (GEO). Our goal is to ensure Shopify stores are properly structured to be discovered and recommended by AI-powered search engines and large language models.

6. What differentiates eCommerce Today from other Shopify agencies?

Our philosophy is simple:

“One retainer. One complete eCommerce team.”

Instead of charging separately for development, design, and marketing services, our clients receive access to senior Shopify developers, UX/CRO specialists, and email marketers under one predictable monthly engagement.

This integrated model allows every part of the growth strategy to work together seamlessly.

7. Can you share a client success story?

We proudly support brands such as VitasupportMD, iSTYLE, and Mobexpert.

For our Shopify Plus clients, we often begin by optimizing technical performance, improving site speed, and fixing conversion bottlenecks. We then implement advanced Klaviyo automation that improves customer retention and lifetime value.

By solving conversion issues before increasing acquisition efforts, our clients consistently achieve strong long-term growth.

8. What leadership principles have helped you build a high-performing team?

I strongly believe in autonomy and accountability.

Rather than micromanaging daily activities, our team members own their responsibilities and are evaluated based on measurable business outcomes such as conversion rates, customer lifetime value, and operational efficiency.

9. How do you encourage collaboration across departments?

Traditional agency silos create unnecessary friction.

Instead, we organize our people into cross-functional client squads managed by dedicated Project Managers. Developers, designers, marketers, and client success professionals work together under one structure, enabling faster communication and better execution.

10. What common mistakes do brands make when scaling online stores?

Many brands invest heavily in paid advertising while neglecting conversion optimization and customer retention.

Driving traffic to a slow website without automated email marketing significantly reduces ROI. Businesses should first optimize conversions, build strong lifecycle marketing systems, and then scale customer acquisition.

11. Which trends will shape the future of eCommerce?

Three major trends will define the next five years:

• Greater ownership of first-party customer data through email and SMS marketing.
• AI-powered search assistants changing how customers discover products.
• Increasing demand for lightning-fast custom Shopify storefronts.

12. What advice would you give entrepreneurs building online businesses?

Understand your unit economics from the beginning.

Know your customer acquisition cost, lifetime value, and true profit margins. Focus on building an authentic brand that transforms one-time buyers into loyal repeat customers instead of relying solely on paid advertising.

13. What achievement are you most proud of?

I’m proud of building an independent team of more than 30 world-class eCommerce specialists while maintaining a perfect 5-star rating across leading agency directories such as Clutch.

14. What exciting developments can we expect from eCommerce Today?

We’re expanding our operational presence across North America to better serve our growing portfolio of U.S. and Canadian DTC brands.

Additionally, we’re introducing specialized AI-powered Shopify optimization audit frameworks to help businesses maximize performance in the evolving AI search landscape.

15. What message would you like to share with aspiring entrepreneurs?

Execution always beats endless planning.

Launch your business, analyze real customer data, listen carefully to your audience, iterate quickly, and stay committed to creating genuine value. Consistent execution is what ultimately drives long-term success.
