BUILT & SOLD

Arbitrage Guru

Wholesale in the e-commerce sector.

Case: ezfox from 0 to 300k ARR

Phase 0: partners before anything else

First move: finding affiliate sales partners already active in the space — close enough to the audience that their pain points were on the table before anything got built.

Audience before product

eBay sellers were reachable before the first line of code existed. I knew where they were and what their day cost them.

Sales through affiliates, not ads

People with reach in the niche do the selling, on commission. No budget burned up front.

One flow instead of a pile of features

Research, listing, price, stock — in one flow, straight out of the Chrome extension.

Scale where it pulls

Once the channel worked, we widened it instead of diversifying: 3.5× revenue in three months, 300k ARR in the first year — no outside capital, no full-time employees. Revenue grew massively, and so did the margin we kept.

From 2026: structures over solo effort

Since 2026 a real sales team is in place — structures that generate constant cash flow from different audiences. To be continued.

Scaling bootstrapped means you cannot afford a channel that only works with budget.

That constraint pushed ezfox early towards sales that keep running without me.

„Was ich besonders hervorheben möchte, ist der Support. Vor allem Enrico nimmt sich wirklich Zeit und hilft einem weiter. Über Discord ist eigentlich immer jemand erreichbar."

„Mit wenig Vorerfahrung und Zeit haben die zwei Gründer und das tolle Support-Team uns wirklich von Beginn an an die Hand genommen."

T S · TRUSTPILOT · 08/2026

Five theses

Large parts of SaaS will die.

Nobody will have to bend to a piece of software anymore.

No software without access to an audience.

No agent without evals. Otherwise it is gambling with extra steps.

Sales that only runs through the founder is not sales.

WHY

Until now companies adapted their processes to the software. With AI that flips: individual solutions get built around the processes that already exist.

That removes a large share of interchangeable SaaS software.

SO

Now is the moment to position yourself: solidify your own product and build the enablement teams need to actually work with AI.

What a SaaS is actually worth

DRIVERS

A funnel that sells without me

Own infrastructure instead of building blocks

Growth that holds for months

A stable subscription base

DRAGS

Sales depends on the founder

Dependency on third-party APIs

Churn shrinking the base

A single market

The multiple is not made in the pitch. It is made in the months the numbers keep running without you.

Valuation logic in the newsletter, with real cases.

From Lake Constance into code.

It was clear early on: computers. And one thought that drives everything to this day — almost anything can be optimized and improved. That drive runs through every station.

It started in e-commerce wholesale: purchasing, margins, logistics. If you earn money there, you know every step of the process.

Those steps became software. ezfox now automates Amazon-to-eBay dropshipping; packfox and invfox build on the same platform.

ZunderTrack came next: time tracking for freelancers, permanently free. Vericaro brings repair tracking to the workshop.

At ETHGlobal Cannes we built a web3 prototype: agents paying agents, with World ID as proof of humanity — a point that keeps moving further into focus.

Every article goes to the newsletter first — then it lands here.

06 / IDEA → MARKET

You know a niche. We build the software.

You come from an audience, you have access to a market and you see every day what is broken there — but you lack the team to turn that into a product.

That is exactly how our projects start: we develop, run and scale the solution with real experts. You open the market — and earn an ongoing share as the idea partner.

HOW IT WORKS

01 NDA before the first deep-dive — your idea stays protected.

02 Clear written agreement on your idea-partner commission — set up legally clean.

03 Execution fully on us: development, operations, sales. You bring market access and niche knowledge.

04 If it works, both sides earn long-term — if it does not, you risked nothing.

07 / NEWSLETTER
