One Point of Contact. A Full Bench Behind It.

Every account runs through the same four capabilities we use across the entire business: Growth Strategy, Retail Media, Content, and Insight Intelligence. Instead of one generalist covering all four, we bring in the specific specialist each one needs.

  • Growth Strategy
  • Retail Media
  • Content
  • Insight Intelligence

  • Account strategy and planning built around your goals, not a one-size-fits-all playbook.

  • PPC, DSP, and advertising that turns ad spend into predictable, profitable growth across every channel you sell on.

  • Listing optimization, photography, and video that convert browsers into buyers.

  • Custom reporting and data intelligence so you always know exactly how your brand is performing, and what to do next.

No Account Manager Rotation. No One Learning on Your Dime

Most marketplace management runs through layers: a sales rep who sells you, an account manager who inherits you, junior staff who actually touch your account. Infix skips the layers. The person managing your strategy is the person you talk to.
That direct line means faster decisions, fewer dropped details, and accountability that doesn’t disappear after onboarding.

What Clients Say

Austian and Infix consistently stayed on top of our inventory levels and sales, while at the same time identifying weak points and opportunities for improvement. They were persistent and solution focused, even when obtaining information and responses from our team was sometimes a slow and labor-intensive process. Their diligence, responsiveness, and willingness to push issues forward make them a valuable partner in managing and growing our account.

Jonathan Levy

President, DIG Corp

Infix has been vital in helping Western Stage Props establish and grow our presence on Amazon. Their team provides in-depth reporting and analysis that gives us a clear understanding of what is working, where the opportunities are, and what needs attention. They’ve also customized their reporting around exactly what we need as a business instead of giving us generic reports. Their knowledge of Amazon, attention to detail, and hands-on approach have made them a valuable partner for us.

Kyle Petersen

President, Western Stage Props

We have had an excellent experience working with Austian and the team at Infix. They have been extremely knowledgeable and have helped us successfully onboard products into Amazon FBA, manage inventory, coordinate product labeling, and improve our Amazon content and images. They understand Amazon Seller Central and FBA very well and have been a valuable resource as we continue to grow our Amazon business.

Who's Behind Infix

Austian Carter, Founder & CEO

I’ve spent my career working inside eCommerce, marketplace management, and digital marketing, helping brands solve the problems that come with growing on Amazon and other major retail platforms.

Before building Infix, I worked with brands ranging from emerging businesses to established companies like Molex, Adidas Outdoor, Mavi Jeans, and Aetrex. That experience taught me that the biggest problem with most agencies isn’t a lack of services. It’s the disconnect between the people making the promises and the people actually managing the account.

That’s why I built Infix differently.

I stay directly involved in the strategy and direction of every account we manage, while bringing in specialists across advertising, content, catalog management, and data when their expertise is needed.

You get senior-level attention from someone who understands the entire business, backed by the specialists needed to execute it.
