The window is always open.
& It is always not for long.
The best companies being built right now will define their markets. The ones who move with intention — and with the right partners — will own them. The ones who wait will watch someone else do it.
Three things every serious
founder is thinking about.
The founders we back are positioning for something larger. The window to own a market, to become the name that defines a category — that window opens and it closes. Here's what we focus on together.
Build something that compounds.
Revenue, market position, customer loyalty, team depth — each year should make the next one easier. We help you build the kind of company that gets more valuable every quarter, not just bigger. The founders we work with aren't optimizing for this year. They're building for the exit or the era that comes after it.
Become the name in your market.
There's a difference between a company that competes in a market and one that defines it. Category leaders attract the best customers, the best talent, the most favorable acquisition terms, and the most durable multiples. We work with founders who are building to lead — and we help them get there faster than they would alone.
The market won't wait for you.
Every category has a moment where the leaders separate from the rest. It's rarely obvious in real time — but it's always obvious in hindsight. The companies that moved decisively with the right capital and the right strategy at the right moment are the ones we remember. The ones that hesitated are the ones we've forgotten.
Not a board seat.
A real partnership.
We've been on both sides of this. We know what it feels like when a capital partner shows up with a framework that doesn't fit your company. We know what it feels like when someone in your corner actually helps. We try hard to be the second thing.
We don't impose playbooks. We show up with specific expertise and use it in service of your vision, not ours. Help you see further, move faster, and get to the outcome you want on your own terms. That's the whole job.
"The best thing we can offer isn't capital. It's having been where you are — and knowing how it turns out."
Where we see the
biggest openings.
These aren't trends we're chasing. They're patterns we've watched build for years — creating real opportunity for founders who are moving with intention.
AI is rewriting the rules of every B2B category — and most incumbents are moving too slowly.
The companies that weave AI into their core product — not as a feature, but as the foundation — are going to look completely different from their competitors in three years. Most incumbents are retrofitting. Founder-led companies are rebuilding from scratch. That's the advantage.
The window to define an AI-native category in B2B is open right now. The founders who move decisively will own the next decade.
Midwest B2B SaaS is producing category leaders — quietly, durably, and efficiently.
Midwest founders build with discipline. They don't burn cash on optics. They earn customers, keep them, and build real businesses — with higher margins, lower churn, and the kind of fundamentals that strategic acquirers pay premium multiples for.
We're rooted here. We know the founders, the talent, and the market. We're backing the ones who are building something that will matter far beyond the region.
The gap between venture and institutional PE is where the best deals are — and where most capital isn't looking.
Venture exits early, before the company is really built. Institutional PE arrives late, when valuations make real returns hard. The founder-led companies at growth stage — past product-market fit, growing fast, thinking about the next chapter — are underserved by capital that actually understands them.
That's exactly where we operate. Patient capital, operator instincts, no formulas. We're the partner for the stage where the real value gets built.
The founders and companies
we want to back.
We're not running a process. We're looking for specific founders building specific companies. If this sounds like you — reach out. If it's close — reach out anyway. We'd rather talk early than miss it.
If this sounds like you — or close — reach out to carl@harborpe.com. No deck required. No process to start. Just a conversation about where you are and where you're headed. We'll take it from there.
