Focus vs. Opportunity: How Deep Tech Teams Decide Which Markets to Pursue

I’ve watched this conversation play out dozens of times, often in the same room, and it usually gets heated.

One founder sees a product that works and spots opportunity everywhere. E-bikes need it. So do power tools. Vacuums, too. Customers are calling, and inbound is coming from three different segments. The founder’s position is logical: why leave money on the table? Why constrain ourselves when we could be winning multiple markets at once?

The other person — usually the co-founder, the commercial lead, or an advisor who’s seen this before — wants to focus. Win one market. Build a playbook that works. Then replicate it. Their concern isn’t capability, it’s momentum. You can’t win three markets half-heartedly.

Both perspectives are right. That’s the problem.

The Pattern I See in Every Deep Tech Team

This isn’t a personality conflict or dysfunction. It’s a strategic tension that shows up because the company has done something hard: built a product that multiple segments value.

A battery startup I worked with hit this exact wall. The CTO, who’d been leading product development, started seeing the opportunity. “I feel like we’re inherently creating a lag by going after the same segment,” he said. “Are we pursuing deployment based on market pull purely?”

It was a fair question. Real demand from three distinct segments — e-bikes, power tools, cordless vacuums — each with different lead times, decision-making processes, and volume potential. The case for expanding seemed obvious.

His co-founder, running commercial operations, saw it differently. He wasn’t worried about execution. He was worried about learning. “We haven’t won twice the same way yet,” he said. “How do we know our playbook is repeatable?”

Both were identifying real risks. Neither was wrong.

The Question That Actually Resolves It

One question separates a strategic opportunity from a distraction. It doesn’t require debate or opinion. It’s answerable through research.

Do the people you’re selling to in Market A talk to the people in Market B?

That’s it.

If Indian e-bike OEMs don’t overlap with Japanese power tool manufacturers — don’t attend the same conferences, read the same publications, share supply chain connections, or benchmark against each other — they’re not the same segment. They’re different segments. Winning one won’t accelerate winning the other.

This is where most teams get it wrong: they define a segment by the product. “Battery-powered devices.” That’s a product category, not a customer segment.

A segment is defined by the network — the shared conversations, the shared constraints, the people who influence each other’s buying decisions.

One of the battery startup’s customers put it this way: “The nuance behind everyone’s requirements is very different. And the more we explore, the more unique it becomes.”

That’s not a problem. It’s information. It tells you whether you’re looking at one segment with multiple sub-applications, or multiple distinct segments that happen to use the same technology.

When to Focus and When to Expand

The pattern becomes clear once you’re looking for it.

Focus when:

You haven’t won three times in the same customer segment
Your sales playbook still requires founder involvement to close
You can’t point to three customers who bought for the same core reason
Your validation reads as “some customers want this,” not “customers like these are reliably buying this”

Expand when:

You’ve closed three or more similar customers using the same sales motion
New business is coming with minimal explanation of why your solution works
Customers are actively referring you to similar buyers
You could describe your customer profile clearly enough that someone else could find them

The mistake isn’t ambition. The mistake is expanding before you’ve answered the first question well enough to repeat it.

How to Have This Conversation Without It Becoming a Fight

The battery startup solved this by treating it as a hypothesis test, not a direction.

“We’re going to validate the two-wheeler segment by May 1st,” they said. Not “we’re committing to two-wheelers.” Not “we’re moving away from power tools.” A test, with criteria.

What did success look like?

Three or more OEMs confirming the pain as a top-3 problem in their business
Three or more confirming willingness-to-pay at the price point we were testing
Evidence of a repeatable buying motion — not one-off sales, but a pattern

Clear. Measurable. Time-bound. Both founders could get behind it.

When May 1st came and the criteria were met, it wasn’t an argument anymore. It was data. They doubled down on the segment.

That’s the conversation to have. Not “focus vs. expand,” but “what would success in this segment look like, and how will we know when we’ve achieved it?”

The Practical Framework

If your team is having this conversation right now, here’s how to work through it:

Step 1: List the segments where you’re seeing customer interest. Be specific. Not “industrial,” but “Indian two-wheeler OEMs.” Not “power tools,” but “mid-market tool manufacturers in Europe.”

Step 2: For each segment, ask the network question. Do these customers talk to each other? Are they influenced by the same industry voices? Do they attend the same events? Do they share the same constraints?

Step 3: Score each on three dimensions:

Validated pain: Is the problem you solve a top-3 priority for buyers?
Access to buyers: Can you get meetings with the decision-makers?
Reference-ability: Will one win help you win the next one in that segment?

Step 4: Pick one. The highest-scoring segment becomes your focus. Set validation criteria and a deadline. What does winning here look like?

Step 5: Hit that deadline and check the data. If you’ve met your criteria, double down. If not, move to the next highest-scoring segment and test again.

This isn’t about choosing the “right” market. Deep tech companies routinely succeed by being patient with validation, not by picking the optimal segment. It’s about deciding in a way the whole team understands.

The Real Tension

The underlying conversation isn’t focus vs. opportunity. It’s repeatability. Can you do this twice? Can you do it without relying on founder intuition and effort?

One founder sees demand. That’s probably true. The other sees the risk of responding to demand before you’ve proven you can deliver it at scale. That’s probably true too.

The question that resolves it isn’t which market to choose. It’s: what proof would make us confident enough to expand?

Once both founders answer that together, everything else is just work.
