Step by Step: How I’d Build and Sell a $100M SaaS If Starting Again

A practical, founder-level walkthrough of how to build, scale, and sell a SaaS company to a $100M+ exit—covering leverage, unit economics, outbound, predictable growth systems, and how to build a business that runs without the founder.

If I were starting over today, with everything I’ve learned from building and selling iContact, I wouldn’t try to be clever. I wouldn’t chase hype. And I definitely wouldn’t build a company that only works because the founder is holding everything together.

The founders who get to $100M-plus exits tend to do a few very specific things extremely well. They build real revenue before chasing capital. They treat unit economics like oxygen. They make outbound a core muscle, not an afterthought. And they build a company that keeps growing even when the founder steps away.

That’s the game. So let me walk you through how I’d do it again, step by step.

Step zero: decide what game you’re actually playing

This is where a lot of founders quietly lose years of their life.

They build one kind of company while secretly hoping for a very different outcome.

If you want a calm, profitable lifestyle business, that’s a great goal. Truly. But if you want a $100M-plus exit, you’re not just building a product. You’re building an asset someone else will eventually want to own.

A lifestyle business optimizes for freedom and cash flow. An exit-ready business optimizes for durability and transferability. Buyers don’t pay premiums for founder heroics. They pay for systems that run without you.

Once you make that decision consciously, every downstream choice gets clearer. Your job becomes building a machine, not being the machine.

Bootstrap early, but not forever

If I were starting again, I’d bootstrap early to buy leverage. Not because venture capital is bad, but because raising too early puts you in a weak position.

A good practical milestone is getting to roughly $500K in ARR before even thinking about raising. At iContact, we bootstrapped until $1M ARR before bringing in outside capital.

Bootstrapping early changes the psychology of the company. You’re no longer fundraising to survive. You’re fundraising to accelerate something that already works. You keep more control, more ownership, and more optionality. That leverage compounds.

The two mistakes that quietly kill SaaS companies

There are two mistakes I see over and over again, even among smart teams. They’re not exotic. They’re basic. And they compound badly over time.

  • Under-investing in UI, UX, and onboarding
  • Avoiding outbound and hoping inbound magically shows up

Founders love to say, “We’ll clean up the product later.” But friction creates churn, support burden, and slower expansion. Those problems don’t get easier as you scale.

And avoiding outbound is just as damaging. Outbound is how you stop waiting for the market to discover you and start creating predictable pipeline. If you want a big exit, you need a real growth engine, not vibes.

Community isn’t a nice-to-have, it’s a multiplier

Founders are more isolated than they admit. And isolation slows you down, especially when you’re making high-stakes decisions.

Getting around other operators who’ve already solved the problems you’re about to face changes your learning curve dramatically. Pricing, hiring, channel strategy, fundraising, exit prep — these decisions get easier when you’re not guessing in a vacuum.

A strong peer group gives you faster pattern recognition, better decision quality, and emotional stamina when things get hard. Your learning curve itself becomes a competitive advantage if you engineer it intentionally.

The growth system: simple, not fancy

The growth system I’d build again isn’t complicated. It’s disciplined. The order matters more than the tactics.

At a high level, the system looks like this:

  • Nail unit economics first
  • Build repeatable acquisition with outbound and paid
  • Layer in market education to compound trust
  • Scale only what stays under your target CAC

A lot of founders skip steps and wonder why growth feels stressful. This system is designed to remove drama. When the math works, growth stops feeling mysterious.

Unit economics are what buyers actually pay for

If you want a nine-figure outcome, your metrics need to make a buyer feel safe.

That means understanding ARPA, churn, LTV, and CAC deeply enough to use them for decisions, not just reporting. Two simple benchmarks still matter: CAC around one-sixth of LTV, and CAC around 50 percent of ACV.

When you know your numbers, scaling feels adult. You know what you can spend, where you’re winning, and why the machine works. And when a buyer looks under the hood, the business feels transferable, not fragile.

Paid acquisition is often the unlock from $1M to $10M ARR

A lot of SaaS companies stall because growth is still dependent on founder hustle or organic luck.

Paid acquisition is what turns “we can grow” into “we can grow predictably.” But it only works if you treat it like an experiment, not a lottery ticket. You test channels with small budgets, measure CAC against a clear target, iterate quickly, and only scale when the numbers stay inside your guardrails.

When it works, it unlocks an entirely different growth gear.

Outbound: build the list, then become unavoidable

Outbound isn’t spray and pray. It’s precision.

You start by building a focused list of ideal accounts. That list becomes an asset. You reuse it across email, LinkedIn, and ads so prospects experience repeated, consistent exposure.

The playbook is straightforward:

  • Build a real ICP-based lead list
  • Run outbound email and LinkedIn against it
  • Show matched-audience ads to the same accounts
  • Create consistent omnipresence

When someone sees you in their inbox, on LinkedIn, and in ads, you stop feeling like a stranger. Familiarity lowers resistance.

Market education is the underrated growth lever

Education creates demand.

If your buyer doesn’t fully understand the problem you solve, your job as a founder is to teach the market. That shows up in outbound messaging, but also in content.

This doesn’t require becoming a media company. Three hours a week creating educational content is enough to compound trust over time. When you explain problems clearly, share frameworks, and publish lessons from the trenches, buying starts to feel lower risk. Sales cycles shorten. Conversion rates improve.

Scaling means the company has to run without you

At some point, the founder has to stop being the operating system.

If you disappeared for 30 days, would the company still hit numbers? Would growth continue without heroics?

Buyers discount businesses where the answer is no. Scaling for an exit means hiring real leaders, building processes, and letting go of control in the right places. Top-dollar exits go to companies that perform without the founder in every decision.

Fundraising: accelerate what works, don’t discover what works

Raising money doesn’t create product-market fit. It amplifies whatever you already have.

That’s why I’m cautious about raising before around $1M ARR and careful about dilution. Raising more than one times ARR too early can put you in an ownership position you regret later.

The best use of capital is simple: prove repeatable acquisition with healthy unit economics, then pour fuel on the fire.

Exit prep is both a milestone and a process

A $100M-plus exit doesn’t just happen because you hit a revenue number. It’s a process you run.

A common milestone is reaching $3M to $5M ARR before seriously preparing for an exit. From there, it’s about tightening reporting, reducing founder dependency, and running a competitive process with experienced advisors.

Exit prep typically includes:

  • Clean, credible metrics
  • A clearly transferable growth engine
  • Multiple interested buyers
  • Strong negotiation on terms, not just price

The process itself can change outcomes by tens of millions.

The real takeaway

The roadmap isn’t complicated. It’s disciplined.

Bootstrap early so you keep leverage. Get your unit economics right. Build outbound and paid acquisition into a repeatable system. Support it with steady market education. Hire leaders so the company runs without you. Raise capital only to scale what’s proven. And when the time comes, run a real exit process so you don’t leave money on the table.

Do the basics extremely well, for long enough, and a $100M-plus SaaS exit stops feeling like a dream and starts looking like the natural result of how you built the company.
