The Next 1,000 eBays

There are 57 million sellers on eBay. Most of them hate it.

They pay 13% in fees. They fight an algorithm that buries their listings. They compete with counterfeits and dropshippers who can't tell the difference between a 1960s no-feet PEZ dispenser and a Dollar Tree novelty.

And after all that, their customers don't remember their store name. They remember eBay.

The era of one-size-fits-all marketplaces is over.

Every collecting community deserves its own marketplace. Not a subfolder on eBay. Not a hashtag on Etsy. A real home. Nerdbase is the platform that powers all of them.

The Seller Problem

Talk to a collectibles seller for five minutes. The story is always the same.

They run a Shopify store. They list on eBay. They cross-post to Mercari. They manage a Beehiiv newsletter. They track inventory in Excel. They check prices on three different apps. They scan barcodes with one tool and manage shipping with another.

It's insane.

In the age of AI, selling a collectible should be as easy as sending a text. Instead, these sellers duct-tape together eight different services and pay a subscription to every single one.

Nerdbase exists to end that. One platform. Marketplace, storefront, community, reputation, price charting. Everything a seller needs, in one place. No more duct tape.

Why Vertical Marketplaces Win

There is no "eBay for PEZ." There is no "eBay for yo-yos." There's just eBay. And collectors have put up with it because nothing better existed.

But every collecting community has its own language, its own grading standards, its own culture. A PEZ collector doesn't think about rarity the same way a yo-yo collector does. A vintage toy buyer searches differently than someone hunting for a specific One Drop colorway.

Forcing them into the same search box is lazy product design masquerading as scale.

Vertical marketplaces fix this. Each one speaks the community's language. Organizes inventory the way their brains work. Features the sellers they already trust. Feels native. Because it is.

Whatnot figured this out for live auctions. StockX figured it out for sneakers. TCGPlayer figured it out for trading cards. But no one has built the platform layer that lets you launch a native marketplace for any collecting vertical.

That's Nerdbase.

The Platform Underneath

Every Nerdbase marketplace runs on the same infrastructure. Same payments, same authentication, same search, same seller tools, same buyer protection. But each vertical is wrapped in an experience that feels purpose-built for that community.

PEZ collectors see PEZ language, PEZ categories, PEZ culture. Yo-yo collectors see theirs. Same spine. Completely different skin.

This architecture means every new vertical launches faster than the last. The playbook compounds. What took weeks for vertical one takes days for vertical five. Each new launch is pure margin on shared infrastructure.

Built by One Person. Powered by AI.

Our founder, Ricky Eckhardt, has shipped eight marketplaces over his career. GoCamp (van rentals, $4M GMV as sole engineer). BookOutdoors (founding engineer, acquired by Hipcamp). Fitted, Inc. (B2B marketplace powering $100M+ GMV across 500 shoe stores). Before that, building AI systems for NATO military intelligence in combat zones.

He built Nerdbase alone. One person using AI agents for code review, QA, market research, content creation, and financial analysis. AI handles roughly 70% of execution so the founder can focus on the 30% that matters. The conversations with sellers. The product decisions. The taste.

Automation is not the moat. Judgment is.

Early Traction

Nerdbase is six weeks old. Here's what's real.

13 sellers converted from Shopify in the first month. Over $60K in inventory listed. Zero dollars spent on ads. Every seller came through direct outreach and community word of mouth.

$2,700 in GMV on $150/month total burn.

Three verticals live. Nerdworth (vintage toys and art slabs). Sugrworth (PEZ dispensers). Yoyoworth (yo-yos). Each one looks native to its community.

470+ users. All organic.

These are small numbers. That's the point. The model works at small scale. It works without paid acquisition. It works with one person running the show. Now imagine what happens when we add the next ten verticals.

The Vision

Not one giant marketplace. A thousand specialized ones.

A $10M niche is a rounding error to eBay. But it's everything to the 500 sellers who live there. Stack a thousand of those niches on a single platform and you have something enormous that no generalist can touch.

Sellers get lower fees, better tools, and a community that knows their name. Buyers get a shopping experience designed for the way they actually think. The platform gets compounding economics with every vertical added.

The next great marketplace company won't be one marketplace. It will be the platform that powers all of them.

We're building it.
