10 Truths No One Tells You About Building a Deep Tech Team
You Don’t Scale Science. You Scale People.
People love to call it “soft skills”.
Communication. Leadership. Hiring. Culture.
But in Deep Tech? Those aren’t soft.
They’re survival.
Your invention means nothing if you can’t convince brilliant people to join you.
Your PhD doesn’t matter if your team can’t work through conflict without imploding.
Your runway is a death sentence if you don’t know how to lead through chaos.
If you’re building a deep tech startup, let’s start with some brutal honesty.
Your product might be revolutionary. Your IP might be defensible. Your prototype might even work.
But unless you build the right team around it, none of that matters.
Let me say it again for the people in the back of the pitch room:
You don’t scale science. You scale people.
Too often, founders in deep tech think that what they’re building is the business. They obsess over the hardware. The chemistry. The experimental model. The lab result. And in doing so, they treat the team as a checkbox slide on their pitch deck—when it should be the main event.
If this sounds like you, take a breath. You’re not alone.
But it’s time to change how you think about team-building in deep tech—because that’s where investors are placing their bets. Not just on what you’ve built. But on who is building it.
10 Truths No One Tells You About Building a Deep Tech Team
✅ Truth #1: A Great CTO Can’t Save a Misaligned CEO
“The most powerful technology in the world can’t compensate for silence in the leadership room.”
Let’s be real for a second: building a company around a breakthrough tech is hard enough. But doing it with leadership friction at the top?
That’s game over—before it even starts.
The CEO-CTO dynamic is not a formality. It’s not a title alignment or a quick intro slide in a pitch deck. It’s the operating system of your company.
In deep tech, where your science is still fragile and your commercial story is still forming, this partnership isn’t just important—it’s existential.
Here’s what most founders miss: your CTO can be world-class. A PhD, published in Nature, five patents, a wizard in the lab. But if your CEO is misaligned—either overhyping tech that isn’t ready or shutting down tough engineering trade-offs—none of that brilliance gets to market. It just dies in tension.
VCs see this. They test for it.
Want a real example?
One early-stage climate tech startup had a prototype that stunned corporate partners. But the CEO kept promising timelines the CTO couldn’t hit. Three board meetings in, the investors stepped back. Not because the science didn’t work—but because the team didn’t.
On the flip side, take a hardware startup we saw come out of a prestigious US university: the CEO handled investor heat with grace, and when a technical question came up, she turned to her CTO, paused, and said, “I think you’ll love his answer more than mine.” That’s not just collaboration. That’s trust as choreography.
“If a CEO interrupts a CTO’s answer in diligence, it’s a red flag. We’re not just judging the answer. We’re judging the trust.”
If you’re the CEO, ask yourself: Am I creating space for my technical co-founder to lead?
If you’re the CTO: Do I trust my CEO enough to say what’s really not working?
Because if the answer is no—your startup isn’t in stealth. It’s in denial.
✅ Truth #2: Leadership is Learnable
“If you’ve mastered complexity in the lab, you can learn to lead through it in the field.”
Let’s be honest: most Deep Tech founders didn’t set out to be CEOs.
You were in the lab. In the field. In the code.
You didn’t spend years studying physical-chemistry, catalysis, or statistical thermodynamics with the end goal of negotiating salaries, setting up option pools, or pitching to VCs who don’t even understand your field…And so, yes — sometimes you don’t feel trained for this…
But yet… here you are.
And you’ve got something big on your hands.
Here’s the truth no one says out loud:
You don’t have to start as a great leader. You just have to commit to becoming one.
There’s a myth that “business” and “science” are separate worlds. But if you’ve spent years optimizing experiments, navigating peer review, leading research teams—you’ve already got the core muscle: structured problem-solving.
Business is just a new system. It has its own language: cash flow, CAC, EBITDA. It has new tools: board decks, CRM funnels, option grants. But the logic? The mental model work? That’s familiar territory for you.
The real leap isn’t intelligence—it’s identity.
Can you embrace being the person who makes imperfect decisions with imperfect data?
Can you go from being the expert to the facilitator of experts?
Can you learn to let go of control, without letting go of accountability?
Founders who make that shift unlock a second kind of compounding—the ability to scale themselves.
And scaling yourself means:
Finding a mentor two stages ahead of you.
Joining CEO groups where it’s safe to ask dumb questions.
Reading investor updates from other founders to spot patterns.
Running retros not just on product, but on your own behavior.
Learning to coach instead of correct.
There is no perfect founder.
But there is one habit nearly every successful one shares: they are obsessed with learning faster than the company grows.
If you can learn fluid mechanics, CRISPR, or quantum photonics—trust me, you can learn leadership.
You just have to decide it’s part of the job.
Because in Deep Tech, it is.
✅ Truth #3: Investors Read Your Team, Not Just Your Deck
Most Deep Tech founders spend weeks obsessing over their pitch deck—perfecting the TAM slide, debating font choices, tweaking the tech diagram on slide seven.
But the truth? The deck’s not what closes the round. You are.
In early-stage Deep Tech, most startups don’t have customers. Or revenue. Or a shipping product. So what do investors have to go on? The team. Always the team.
They’re not just scanning credentials. They’re scanning confidence. Clarity. Chemistry. They’re asking:
“Does this team actually know the terrain they’re trying to navigate?”
“Have they lived the problem long enough to see around corners?”
“Do they have the edge, the stamina, the self-awareness to figure it out under pressure?”
Because here’s the uncomfortable reality: ideas evolve. Business models pivot. Timelines stretch.
But the team? That’s the constant. If they can’t grow, adapt, and execute as the stakes rise, the rest doesn’t matter.
A founder with a decade inside the target industry? That’s signal.
A CTO who’s been publishing on this tech since grad school? Signal.
A first hire who left a FAANG job to join the mission? Huge signal.
And investors are paying attention to every micro-detail. How do you communicate as a team? Who jumps in? Who defers? Who owns what? Do you feel like a team with velocity—or a collection of smart individuals trying to wing it?
Here’s the mindset shift: you’re not pitching a product. You’re pitching a vehicle. One capable of building something that doesn’t exist yet, in a space that might not even be fully formed.
If investors believe in the team, they’ll believe in the story.
Even if the ending hasn’t been written yet.
✅ Truth #4: Culture Isn’t Slides—It’s Systems
Let’s kill the vibe of the word “culture” for a second.
Because in startup land—especially Deep Tech—it’s been watered down to ping-pong tables and vague values like “integrity” or “collaboration” stuck on a slide at the end of a pitch. Cute, but meaningless.
Real culture? It’s infrastructure. It’s how decisions get made when there’s no rulebook. It’s how your team behaves when things get messy—because they will. It’s what holds you together when the tech fails, the prototype catches fire (literally), and you’re three months from running out of cash.
Here’s the thing most founders get wrong: culture doesn’t “emerge.” You build it. You operationalize it. From day one.
