Multiple founder conversations this past month. Same pattern, different companies.

Brilliant. Some deeply technical. So immersed in what they were building that when I asked "but what does this actually do in the real world for the person buying it?"—there was a pause. Not because they didn't know. But because they'd been so deep in their own language for so long, they'd forgotten the rest of the world doesn't speak it yet.

It triggered a thought I keep coming back to: building a business isn't just a product problem or a technology problem. It's fundamentally a translation problem. And if you never establish a common vocabulary with your market, you're essentially talking to yourself.

The Language Lesson Happening in My Living Room

Right now, my daughter is in the middle of learning a smattering of South Indian languages at home. (She gets her Mandarin in school—and I'll be honest, I'm relieved, because that particular translation project is well beyond my pay grade as a parent.)

What's been interesting to watch is how she learns.

The instinct might be to sit her down, run through vocabulary lists, drill grammar rules, and give her a foundational download of the language. Structured. Logical. Efficient.

It doesn't work that way.

What works is contextual learning. Not "let me teach you a language"—but "how do I say this right now, in this moment, for this specific thing I want to communicate?" She wants to tell her grandmother she's hungry. She wants to ask for something specific. She wants to understand what's being said about her (she's 4 and a half—she definitely knows when she's being talked about).

So instead of a dictionary's worth of vocabulary, we zone in on what she needs to say, in the moment, and build from there. Slowly, a working vocabulary forms—not from a syllabus, but from repeated, contextual use. The language becomes a tool to trade value between her and the people she loves.

And here's the part that matters: it's bidirectional. She tells me what she needs to know next. I adjust. She adjusts. It's a constant dialogue—not a lecture.

The PMF Parallel: A Dialogue, Not a Download

This is exactly what Product-Market Fit is.

Not a destination you arrive at. Not a slide in your deck that says "we've validated demand." It's an ongoing, evolving dialogue with the market—and it requires, at every stage, a common vocabulary between you and the people you're trying to serve, sell to, recruit, and fund.

When I'm in early PMF conversations with founders, I'm essentially asking: have you established a common language yet? Can your customer say back to you what problem you solve—in their words, not yours? Can your investor describe what you do to their LP without the technical scaffolding you've built over 18 months?

If the answer is no, it doesn't mean the product is wrong. It means the translation layer is missing.

The Technical Founder's Trap

Technical founders—and I say this with enormous respect —are particularly susceptible to this.

There is just so much inherent excitement in the technology. The architecture is elegant. The model is novel. The infrastructure decisions are genuinely interesting. And they should be—that depth is what makes great technical products real.

But the market doesn't buy architecture. It buys outcomes.

And the gap between "here's what we built" and "here's what it does for you" is a translation problem. It requires building a common vocabulary that works at multiple levels:

  • For customers: What does this do in my world, in plain language, in the context of my actual problem?

  • For investors: What is the size of the problem, why now, and what does adoption look like as this scales?

  • For team members: What are we actually building towards, and how does my role connect to that?

  • For partners: Where does this fit in the ecosystem, and why does it make your offering stronger?

Each audience needs a different dialect of the same language. And none of it works if the core vocabulary hasn't been established first.

Building the Common Vocabulary

In my daughter's language learning, we didn't start with grammar. We started with the words she needed most—the ones that created immediate value in her daily life.

Founders need to do the same thing with their market. Don't start with the full feature set. Start with the vocabulary of the problem—the words your customer uses when they describe the pain, the friction, the cost of the current situation.

Then—and this is the part most teams skip—listen to how they describe your solution back to you. That feedback is your vocabulary lesson. When a customer says "oh so it's like X but for Y"—even if that analogy makes you cringe—that's a signal. That's the market telling you which language it wants to use to understand you.

Use it. Adjust. Build from there.

Because here's the thing I've seen consistently across early-stage companies (including the mistakes i've made): the teams that find PMF fastest aren't always the ones with the best technology. They're the ones who've established a working dialogue with the market early—who've been willing to adjust their vocabulary based on what the market actually understands and values.

The Dialogue Never Stops

When my daughter gets something new, the vocabulary expands. As her world gets more complex, the language needs to grow with it. It's not a one-time exercise—it's a continuous, iterative loop.

Same with your business.

PMF isn't a fixed point. Markets evolve. Customer needs shift. New competitors reframe the category. What your product "means" to the market today may not be what it means in 18 months. The companies that stay relevant are the ones that keep the dialogue open—that keep listening, adjusting, and rebuilding the shared vocabulary when the context changes.

So here's the question I'd leave you with—especially if you're in the early stages of building:

Can the people you most need to convince (customers, investors, team) describe what you do in their own words? Not yours. Theirs.

If not, that's your most important product problem right now. Not the roadmap. Not the architecture. The translation.

Are you working through this right now? Drop it in the comments—I'd love to hear how you're thinking about the vocabulary problem in your space.
