Investment and Monetization, Through the Lens of Lump Sum vs. Installment

Making money comes down to investment, and monetization. You need both of these flows.

Working as a publishing editor, I get to meet people across all kinds of fields, and I've noticed there are just as many different ways to make money. But when I look closely at the patterns, it always comes down to investment and monetization playing out as some mix of lump sum and installment.

Let me lay out how lump sum and installment play into the investment-and-monetization process, using a simple 2×2 matrix. It's a concept I never once learned in my economics degree or business school coursework — and yet it's genuinely simple.

First: Lump-Sum Investment → Lump-Sum Monetization (The Hunter Model)

This is where you build a product or service, deliver it, and monetize it all at once.

Think custom software development or large-scale construction projects — made-to-order work. You build exactly what was ordered, deliver it, and collect one large payout. It's a structure built on trusted counterparties — B2B deals, government contracts — where you produce and deliver based on an established relationship.

I like to compare this to hunting. Bag a mammoth, deliver it, and you make a big payday.

The upside is that one signed contract guarantees a large sum. The downside is that once the contract ends, you're back to hunting for a new client. Two things are worth checking here: whether you actually have the ability to bring down a mammoth, and whether you're connected to a reliable buyer who needs one.

Second: Lump-Sum Investment → Installment Monetization (The Farmer Model)

Here, you build the product up front, and revenue comes in as people pay for it piece by piece over time.

This covers wholesale buying, or planning a product and bringing it to market yourself. It's manufacturing-based, but it also spans the whole process — from creating the product to building a market touchpoint to selling it. You invest up front, hold the product as inventory, and sell it down over time.

Publishing fits this model exactly. We work with an author to shape a manuscript, manufacture the physical book, and warehouse it with a logistics partner. When a bookstore places an order, it gets distributed through the supply chain.

Two things matter here: cutting your upfront cost — your cost basis — and securing content that will keep selling steadily. A product, once made, needs to be able to generate cash flow as a steady seller.

This model is booming in the digital world. SaaSsoftware as a service is the classic example — you build the software once, then monetize it in installments through subscription fees. According to Fortune Business Insights, the global SaaS market is projected to grow from about $266.2 billion in 2024 to $315.7 billion in 2025, an 18.6% year-over-year increase, and is forecast to top $1 trillion by 2032. South Korea's subscription economy has likewise grown steadily since it stood at roughly KRW 26 trillion in 2016, according to the KT Economic Management Research Institute.

The core requirement is the same either way: the financial staying power to absorb the upfront investment, and product quality good enough to keep it selling.

Third: Installment Investment → Lump-Sum Monetization (The Startup Model)

Here, you invest gradually to build up value, then cash out all at once.

For an individual investor, this looks like buying up stock bit by bit and selling it off at a good price. For a company, this is the startup model. You spend three to five years building the company hard, and once it's grown enough, you cash out in one shot through an M&A or an IPO. This is what people call an "exit."

This structure becomes clear when you look at some notable exits in Korea: Delivery Hero's acquisition of Woowa Brothers (Baemin), Match Group's acquisition of Hyperconnect, Coupang's IPO on the New York Stock Exchange, and Zigbang's roughly KRW 23 billion acquisition of Hogangnono, among others.

Still, the reality is far from easy. The average exit rate for Korean startups sits at around 2.3%. According to the Startup Genome report, the average time to exit in Seoul has stretched to 9.2 years, and data from the Startup Alliance shows domestic startup M&A deals falling sharply, from 150 in 2022 to 88 in 2023. The Federation of Korean Industries also notes that while 82.8% of exits among the world's top five unicorn ecosystems happen via M&A, that figure is just 52.9% in Korea — a sign the M&A exit environment here still has room to mature.

This path calls for a long-term investment mindset. It's hard to make money quickly this way, but there's the potential for a big payout. The flip side — and the real risk — is that you might end up with nothing to show after years of work. It's only worth attempting if you have both a strong idea and the execution to back it up.

As a side note, a book published by my company, People Betting on the 1% Chance, features interviews with venture capitalists who invest in startups. As the saying goes, know yourself and know your enemy, and you'll never lose a battle. If you're a startup preparing to raise venture funding, you may find some useful insight there.

Fourth: Installment Investment → Installment Monetization (The Content Creator Model)

Here, you invest a little at a time and earn a little at a time in return.

Creators working in YouTube, blogging, or online courses fall into this model. If you run a blog, you post content every day that fits the character of the blog you're trying to build. At first it looks like nothing is happening, but over time, views climb and ad revenue starts coming in.

It's a matter of investing consistently to earn consistently. Quit partway through, and the income disappears with it — consistency is everything.

I'd encourage authors considering publishing a book to think about this model too. From the publisher's side, it's the second model described above — lump-sum investment, installment monetization. But from the author's side, it looks different. If you invest time consistently, day after day, building up content, you can eventually monetize it in installments through the opportunity that publishing provides.

One caution here: let go of the idea that a single piece of content will pay off in one lump sum. Dramatic breakout cases do happen occasionally, but lump-sum monetization isn't realistic for everyone. You need to build your business model around installment investment — steadily creating content — leading to installment monetization.
