Kindness and data. That's the whole company.

Renza is a St. Louis account management agency for brands selling on Amazon and Walmart. It was started by two friends with two goals, and named for the two ideas it runs on.

Ren ci is how we treat people: clients, employees, shareholders, the person on the other end of every email. With respect, and with the assumption that the relationship is meant to last. Our average client stays more than three years.

Renko is how we decide things. Not on instinct or on what the last account needed, but on what this account's numbers say. Every change we make is one we can measure, and the ones that don't work get reversed.

Put the two together and you get the job: treat people well, and let the data drive continuous improvement.

Two goals, in the order we wrote them down

An exceptional experience for our clients

One named manager who knows your account, answers the phone, and is measured on your revenue. No handoffs, no ticket queue, no surprises in the monthly report.

A best-in-class workplace for our people

Managers who are treated well manage accounts well. We built the company so the people doing the work want to stay — which is why our clients get the same person year after year.

How that shows up in the work

  • One manager, the whole account

    Advertising, catalog, creative and promotions are run by one person who sees all of it, so decisions in one area don't quietly undo work in another.

  • Plain numbers

    Reports say what we changed, what happened, and what we're changing next. If a number went the wrong way, it's in the report with the reason.

  • Audit first, always

    Every engagement starts with a written audit of the account. You know what needs doing before you pay for any of it.

  • Built for long relationships

    We'd rather grow an account for years than win it for a quarter. The retention number is the one we watch most closely.

Co-Founder, Renza

I've spent over a decade in account management and e-commerce. Everything I do comes down to two things: building a genuinely great experience for clients, and building a working environment my team actually wants to be part of. Renza exists because I believe those two things aren't in tension — they reinforce each other.
