When I studied the most profitable software companies in the world, a pattern emerged that nobody talks about openly: the most successful firms do not just sell software; they use their software to build a marketplace they own. Shopify is one example. Amazon is another. Airbnb is another. The software is the tool. The marketplace is the wealth.

The Difference Between Selling and Owning

When I sell you an accounting program, I earn once — the license fee, or the monthly subscription. When I build the same program and use it myself to run accounting for a thousand companies, I earn on every transaction that happens inside the system. The first is a linear model. The second is exponential.

That is the structural gap. Software companies that "keep selling" stay mid-size forever, even when their products are excellent. Software companies that "build a marketplace on top of their tools" become giants.

The NASEY Model: Three Layers

Layer one — software as a tool

For twenty years, NASEY has been building websites, e-commerce stores, mobile apps, ERP systems, and SaaS products. That is the "tool." The client pays once (or subscribes), and receives a product.

Had we stopped there, we would be a competent software agency — mid-sized, reasonably profitable. But one observation nagged: every sale our clients executed inside their stores flowed entirely to them. We had built the pipe; the water ran only in one direction.

Layer two — the marketplace we own

In 2024 we launched Buy Egypt. It was not a competitor to our clients. It was an extension of them. Instead of each merchant selling in isolation, they all entered a unified platform that put them in front of customers they had never reached.

The economic difference: on layer one, we sell a tool for a million pounds, once. On layer two, we take a 5–12% commission on every sale that happens on top of our platform. At a million transactions a year, even a small commission produces a fundamentally different business.

Layer three — enablement and shared upside

The smartest layer is neither the software nor the marketplace. It is expanding the circle of beneficiaries. The affiliate program pays any Egyptian a 5–8% cut of sales they bring in. The tiered subscription model (Starter, Growth, Pro, Enterprise) lets the merchant self-select their level. All of this creates an ecosystem in which every party wins.

A company whose success serves only its founders is fragile. A company whose success serves thousands becomes part of the economy itself.

Why This Model Is Harder to Execute

Selling tools is relatively easy: you build a product, market it, collect payment. Building a marketplace is an order of magnitude harder:

  • The chicken-and-egg problem — merchants will not come without customers, and customers will not come without merchants. The solution requires simultaneous investment on both sides.
  • Heavier infrastructure — payment processing, shipping, support, reviews, dispute arbitration. None of this was required when you were only selling tools.
  • Reputation is now yours — when a merchant fails inside Buy Egypt, the platform's reputation carries the fallout, not just the merchant's. That forces strict quality control.
  • Delayed profitability — the model loses money for years, then compounds. Many companies can't hold their nerve that long.

When Selling the Tool Is the Right Choice

Not every founder should build a marketplace. The first model (selling tools) is appropriate when:

  • You do not have the capital or patience to invest for years before profit.
  • Your target market is narrow (a specialized service for large enterprises).
  • You do not want to run complex operations (support, shipping, payments, disputes).
  • You want to preserve a reasonable personal life (marketplaces consume founders).

There is nothing wrong with choosing the first model. Many respected global companies (Basecamp, for instance) deliberately stayed small and profitable. What matters is that the choice be conscious, not accidental.

The Takeaway

If you are an engineer or a founder building a software company today, ask yourself early: do I want to keep selling the tool, or do I want to build the market on top of it? The early decision determines the architecture, the investment, the team, and the patience required.

NASEY chose layer one for its first eighteen years. Only in recent years did we move into layers two and three. Had I made the decision earlier, the journey would have been a decade faster. The lesson: timing matters, and an early strategic decision is worth more than late-stage tactical brilliance.
