The Evolution of Software Development and the Rise of Modern SaaS

The Evolution of Software Development and the Rise of Modern SaaS

There is a machine sitting in a museum in Washington DC that once occupied an entire room.

It weighed 30 tons. It contained 18,000 vacuum tubes. It consumed 150 kilowatts of power every hour it ran. And in 1945, it was the most sophisticated computing device human beings had ever built.

Its name was ENIAC. And the instructions that told it what to do, the earliest ancestor of what we now call software, had to be physically rewired into the machine by hand every single time someone needed it to perform a different calculation.

That was where software began.

Today, the device in your pocket runs software more powerful than anything ENIAC could have imagined. The apps on that device connect to servers processing billions of transactions simultaneously. The companies behind those apps are worth trillions of dollars. And the software industry they represent is the largest and fastest-growing industry in human history.

Seventy years. One continuous story.

This is that story. And it ends with why Lumino Technology, a software company based in Pokhara, Nepal, exists exactly where it does at exactly this moment in that story.

The Beginning: When Software Did Not Have a Name

In the years immediately following World War Two, the people building computers were not thinking about software as a separate thing.

They were thinking about hardware. The machines themselves. The vacuum tubes, the transistors, the physical components that made computation possible. The instructions those machines ran were an afterthought, a necessary companion to the real work of engineering the hardware.

The word software itself did not appear in print until 1958, when mathematician John Tukey used it in a statistics journal almost casually, as if naming something that had existed all along without anyone bothering to label it.

Because in a sense it had.

Every machine needed instructions. But those instructions were inseparable from the machine they ran on. You did not write software and then choose which machine to run it on. You built the machine and then figured out how to instruct it, specific to that machine, specific to that problem, not transferable, not reusable, not a product in any commercial sense.

The companies that owned computers in this era were not buying software. They were buying computation. The thinking, the programming, the logic, that was the work of the engineers they employed, not something purchased separately from an outside vendor.

This had a profound consequence for who could participate in computing at all.

IBM's mainframes of the early 1950s cost millions of dollars to purchase and tens of thousands of dollars per month to operate. The knowledge required to program them was possessed by a tiny number of specialists globally. The infrastructure required to house and power them was available only to large institutions.

Computing was not a tool. It was a privilege. Accessible to governments, defense contractors, research universities, and the largest corporations on earth.

Everyone else was watching from outside the room.

The First Shift: Languages Give Software Independence

The change that started everything came from a woman named Grace Hopper.

In 1952 Hopper developed the first compiler, a program that could translate human-readable instructions into the machine code a computer actually executed. The idea sounds simple now. At the time it was considered almost heretical. Computers, many believed, could only work with precise numerical instructions. The idea that a machine could translate something closer to human language into those instructions struck many engineers as absurd.

Hopper proved them wrong.

Her work laid the foundation for the programming languages that followed. FORTRAN in 1957, designed for scientific and mathematical computation. COBOL in 1959, designed for business data processing. And later, in 1972, the C programming language, which became the direct foundation for almost every major programming language that exists today.

What these languages did was create abstraction. A layer between the human thinking about a problem and the machine executing the solution. You no longer needed to think in binary. You could write something that resembled logic, that resembled thought, and the language would translate it downward into the instructions the machine understood.

This abstraction had consequences that reshaped the entire trajectory of software.

For the first time, software could be written once and run on multiple machines. The instructions were no longer physically wired into a specific piece of hardware. They were portable. They were transferable. They were, for the first time, something that could be thought of as a product independent of the machine it ran on.

The software industry did not exist yet. But the conditions for its existence had just been created.

The 1980s: Software Becomes Something You Buy in a Box

The personal computer changed everything about who software was for.

When Apple launched the Apple II in 1977 and IBM released the IBM PC in 1981, the story of computing stopped being exclusively about institutions and started being about people. Businesses. Homes. Individuals who had never interacted with a computer in their lives suddenly had one sitting on their desk.

And those machines needed software to do anything useful.

Microsoft understood this before almost anyone else. When IBM came to Microsoft looking for an operating system for its new personal computer, Bill Gates and Paul Allen did not have one. They bought one from a small company for $50,000, adapted it, and licensed it to IBM. MS-DOS became the operating system on every IBM PC. And because IBM's design was open enough for other manufacturers to clone it, MS-DOS became the operating system on most personal computers in the world.

From that foundation, the shrinkwrap software era was born.

Companies packaged software into boxes. Wordperfect for word processing. Lotus 1-2-3 for spreadsheets. dBASE for databases. You walked into a store, bought the box, took it home, installed it from floppy disks, and used it. When a new version came out, you bought a new box.

This was the first time most people experienced software as a product. Something you purchased. Something you owned. Something that sat on your shelf next to the machine it ran on.

But the shrinkwrap model had a fundamental limitation that nobody spent much time talking about while it was dominant.

The software in the box did what it did for everyone who bought it. There was no customization. No adaptation for your specific business. No updating without buying a new box. No connection between your copy and anyone else's. The software was frozen at the moment it shipped.

If your business had needs the box did not meet, you had two options. Adapt your business to fit the software. Or pay for custom development that only enterprises with significant budgets could afford.

That tension, between the convenience of packaged software and the necessity of specific capability, would define the next twenty years of the industry.

The 1990s: The Internet Tears Down the Walls

The commercial internet arrived in the early 1990s and changed the fundamental nature of what software could be.

Before the internet, software lived on discs. Distributing it meant manufacturing physical media, packaging it, shipping it through retail channels to stores where customers could find it and buy it. The costs of that distribution chain were enormous. They were a barrier that protected established software companies and kept new entrants out.

The internet made distribution essentially free.

A company could write software, put it on a server connected to the internet, and make it available to anyone in the world with a connection. The marginal cost of reaching one additional user was approximately zero. The geographical constraints that had always limited software distribution simply ceased to exist.

This should have been the moment that transformed everything. And in many ways it was. But the internet of the 1990s was also genuinely new territory. Browser technology was primitive. Bandwidth was limited. The behavioral patterns that would eventually make web-based software feel natural to users had not yet developed.

What the 1990s produced instead was the dot-com boom. An enormous, chaotic, frequently irrational explosion of investment in internet companies building every conceivable form of web-based product and service. The logic was sound even when the execution was not. If distribution was free and the market was global, the potential value of an internet business was effectively unlimited.

Most of those companies failed. The crash of 2000 wiped out trillions of dollars of market value in months.

But the infrastructure the boom built survived. The fiber optic cables. The server farms. The browser standards. The payment systems. The behavioral shift in how people related to the internet. All of it remained after the companies that built it went bankrupt.

And it was exactly the foundation the next wave of software needed.

The 2000s: SaaS Changes the Business Model of Software Forever

In 1999, a year before the dot-com crash, a company called Salesforce launched with what felt at the time like a genuinely strange idea.

What if you did not sell software at all?

What if instead of asking businesses to buy a license, install the software on their own servers, manage the infrastructure it ran on, pay for upgrades every few years, and deal with all the maintenance and security implications of running enterprise software themselves, you simply let them access it through a browser and charged them a monthly fee?

No installation. No maintenance. No upgrade cycle. No infrastructure. Just access.

Salesforce called this model Software as a Service. The rest of the industry eventually called it SaaS.

The timing was not accidental. By 1999 the internet infrastructure was mature enough to make browser-based enterprise software actually usable. Broadband was spreading. Browser technology had improved substantially. The behavioral foundation the dot-com era had laid was paying dividends for the companies smart enough to build on it.

Salesforce proved the model worked. Then it proved it worked at scale. Then the rest of the software industry spent the next decade figuring out that the same model could apply to almost every category of business software that existed.

Human resources. Accounting. Marketing. Customer support. Project management. Communication. Security. Analytics. Every function that previously required an expensive installed software package began its migration to a subscription-based cloud alternative.

The implications for businesses were profound and immediate.

The upfront cost of adopting new software dropped dramatically. Predictable monthly expenses replaced large capital outlays. Automatic updates meant every user always ran the latest version without any action on their part. Access from any device with a browser meant software was no longer tied to a specific machine. And the ability to add or remove seats as the business changed meant software costs could scale with actual usage rather than requiring businesses to overbuy capacity they might never use.

SaaS democratized access to sophisticated software in the same way the personal computer had democratized access to computing itself a generation earlier. Small businesses could now access tools that had previously been the exclusive province of large enterprises, at price points that made sense for their scale.

2007: A Device in Every Pocket Changes Everything Again

The iPhone launched on June 29, 2007.

Steve Jobs described it as an iPod, a phone, and an internet communicator, three devices in one. The audience laughed at the joke. They had no idea they were watching the beginning of a transformation in how software would reach people that would prove to be as significant as the personal computer itself.

What the iPhone did was not just create a new device category. It created a new relationship between people and software.

Before the smartphone, software was something you sat down to use. You opened your laptop. You found the application. You worked. Then you closed the laptop and stopped.

After the smartphone, software was something you carried everywhere. Something accessible in any moment. Something that could know where you were, what time it was, what you had just been doing, and respond to that context in ways desktop software never could.

The App Store, which launched in 2008, democratized software distribution in a way that even the internet had not fully achieved. Any developer anywhere in the world could build an application, submit it to Apple, and make it available to hundreds of millions of people. The barrier between building software and reaching a global audience collapsed to nearly nothing.

Mobile did not replace what had come before. It added a dimension. Software now needed to exist across multiple surfaces simultaneously. The same product had to work on desktop browsers, on iOS, on Android, with experiences adapted for each environment while remaining coherent as a single product.

This complexity was a challenge. But it was also an opportunity. The companies that built mobile-first or mobile-excellent versions of their software products captured audiences that the desktop-only competitors could not reach.

The Cloud: Infrastructure on Demand Changes Who Can Build

Amazon Web Services launched commercially in 2006 with a set of services that most people in the technology industry initially dismissed as a strange sideline for a company that sold books.

Within a decade it had become one of the most important technology businesses in the world.

What AWS, and later Google Cloud and Microsoft Azure, did was take the physical infrastructure of computing, the servers, the storage, the networking, the databases, and make it available as a service. You did not buy a server. You rented computing capacity. You paid for what you used. You scaled up when you needed more and scaled down when you needed less. And you never had to worry about the physical hardware because it was someone else's problem.

The implications for software development were transformative.

Before cloud infrastructure, building a serious software product required significant capital investment. You needed servers. You needed a data center or a co-location facility to put them in. You needed engineers to manage the infrastructure. And you needed to overbuy capacity to handle peak demand, which meant paying for computing power that sat idle most of the time.

After cloud infrastructure, a team of two developers with a good idea and a credit card could build, deploy, and scale a software product to serve millions of users without owning a single piece of hardware.

The capital barrier to building serious software collapsed almost entirely.

What followed was an explosion in software entrepreneurship that the industry had never seen before. Thousands of SaaS companies launched targeting every conceivable niche, industry, and use case. The software market fragmented from a small number of dominant platforms to an enormous ecosystem of specialized tools each serving specific needs better than any general-purpose alternative could.

The 2020s: Every Company Becomes a Software Company

The pandemic of 2020 did not create the shift toward software-driven business operations. It accelerated it by an estimated five to ten years in a matter of months.

Companies that had been slowly, incrementally moving toward digital operations were forced to move immediately. Remote work had to work on Monday morning, not after an eighteen-month transformation project. Customer interactions that had always happened in person had to happen online. Supply chains that depended on physical presence had to adapt to a world where physical presence was intermittently impossible.

The companies that had already built strong digital foundations navigated this period. The ones that had not struggled at a level that was existential for many of them.

But the deeper shift that the pandemic revealed was something more significant than the digitization of existing operations.

It was the recognition, spreading across industries that had never thought of themselves as technology businesses, that software is not a tool businesses use. It is a competitive advantage businesses build.

A logistics company that builds its own route optimization software has capabilities its competitors using generic tools cannot match. A healthcare provider that builds its own patient management platform serves its patients differently than one constrained by off-the-shelf systems designed for the average case. A retail brand that builds its own e-commerce infrastructure controls its customer relationship in ways that marketplace dependency never allows.

The question for businesses in every industry stopped being whether to invest in software. It became whether to buy generic software that constrained them to the average or build custom software that gave them capabilities specific to their competitive position.

More companies every year are choosing to build.

The Rise of Modern SaaS: Where the Market Stands in 2026

The SaaS market that Salesforce pioneered in 1999 has grown into something almost unrecognizable in scale.

The global SaaS market was valued at over $300 billion in 2024 and is projected to exceed $900 billion by 2030. There are now more than 30,000 SaaS companies operating globally. The average business uses over 100 SaaS applications simultaneously. And the category continues to expand as software eats into industries that previously had no meaningful software footprint.

But the SaaS market of 2026 is also more complicated than the clean narrative of its early years suggested.

The per-seat pricing problem has become real for companies at scale. A SaaS tool that costs $15 per user per month is an easy decision for a team of ten. At a thousand users it is $180,000 per year for software you do not own and cannot modify. At ten thousand users the math becomes genuinely difficult to justify.

The integration complexity problem has grown with the SaaS ecosystem itself. When your business runs on 100 different SaaS tools, making those tools communicate with each other becomes its own engineering challenge. The promise of simple, accessible software has been partially offset by the complexity of connecting dozens of specialized systems that were never designed to work together.

The generic capability problem remains the most fundamental limitation. Every SaaS product is built for the average customer in its target market. It serves most of them adequately. It serves almost none of them exactly. As markets become more competitive, the business that is constrained by what its software vendor chose to build for the average case is at a structural disadvantage against the competitor that built software specifically for how it operates.

These three problems are driving a significant portion of the demand for custom software development that defines the current market. Businesses that have outgrown generic SaaS tools, that are drowning in per-seat costs, that need integration capabilities their vendors cannot provide, and that require specific functionality their off-the-shelf tools will never build, are increasingly choosing to build their own.
