We are SellerPlex

The story behind SellerPlex

SellerPlex was founded in 2018 by Nate Ginsburg after years spent building and scaling his own e-commerce businesses on Amazon. He kept running into the same problem: Amazon sellers doing $1M to $20M in annual revenue couldn't find an agency that treated their business like a real operating company. Instead they found specialists siloed into single-channel shops: one agency for PPC, another for supply chain, a bookkeeper who didn't understand Amazon reserves, and a content shop that had never actually launched a listing.

Menno Gottmer joined in 2019 as Chief Operating Officer to scale operations and build out the cross-functional team that makes SellerPlex's full-service model possible. Today Nate leads as Founder & CEO and Menno runs operations across every department.

SellerPlex started as the full-service alternative: one team, one engagement, one point of accountability, covering every operational surface a 6 to 8 figure Amazon brand needs to grow profitably. Nate now serves as Founder & CEO, and Menno as Chief Operating Officer. Both remain actively involved in client strategy and team leadership.

Our purpose and mission

SellerPlex exists to help businesses grow their online success.

We believe every entrepreneur does best by spending as much time as possible on what they are great at, and as little as possible on everything else. So we take on the work that has to be done well but keeps founders from the work only they can do.

Our core values

Our team: 80+ specialists who live inside Amazon every day

SellerPlex is a fully distributed team of more than 80 Amazon operators, analysts, and specialists. Department leads include heads of PPC, Account Management, Supply Chain, Content & Creative, Finance & Bookkeeping, DSP, and Revenue Recovery. Every client is paired with a named account lead and a small cross-functional pod so you always know who is working on your business and why.

Because we work exclusively with Amazon sellers, our processes, dashboards, and SOPs are built specifically for Seller Central workflows, FBA economics, and the compliance edge cases that cost sellers millions each year. The team has managed $7M+ in yearly Amazon ad spend, recovered $3M+ in misplaced FBA inventory and fee errors, and run reordering and restocking across six countries for brands like EMERGE.

Why full-service wins for 6 to 8 figure Amazon brands

Most Amazon agencies are optimized for a single channel. When your PPC agency doesn't know your COGS, when your bookkeeper doesn't track Amazon reserves, and when your supply chain vendor has no visibility into Buy Box wins, the gaps between them quietly cost you margin and growth.

SellerPlex eliminates those gaps. Our PPC team sees supply-chain inventory levels before launching aggressive campaigns. Our supply chain team reviews the finance team's cash-flow forecast before placing POs. Our content team gets daily feedback from account management on listing performance. The result: clients consistently report faster decision cycles, tighter unit economics, and fewer costly coordination failures between functions.

How we work with you

Every engagement starts with a 30-minute Blueprint session where we audit your business across account health, PPC, supply chain, content, and financial operations. We identify the highest-leverage areas to work on first and scope a fixed monthly retainer based on which services you need. Most clients start with a subset (PPC plus account management, or supply chain plus finance) and expand over time as they see results.

There are no multi-year lock-ins, no surprise upcharges, and no account-executive hand-offs once you sign. The team you meet during your Blueprint is the team that will run your business. If you are a serious Amazon brand ready to treat your operation like a real company, we would love to talk.
