Space Lasers, Tissue Samples, and the Pitch That Taught Me Where My Edge Ends

I write a lot about portfolio careers: that is, about diversifying your professional identity, building multiple income streams, and treating your career like an investment portfolio rather than a single-stock bet.

I believe all of it. I’ve lived it. And I’m about to tell you about the time it almost led me off a cliff…

The Setup

A few months ago, I got a warm introduction through Plug and Play Tech Center, the Silicon Valley–based accelerator that connects startups with corporate partners, investors, and service providers across 60+ locations worldwide. If you’re not familiar, Plug and Play runs vertical-specific programs — fintech, deeptech, healthtech, mobility, energy — and serves as a matchmaking engine between early-stage companies and the people who can help them scale.

The introduction came through their APAC pipeline. Two Asian startups, both in Plug and Play’s ecosystem, were looking for fractional strategic support as they prepared for US market entry. Plug and Play connected them with me through my company, APR Strategic Consulting; they had seen my work, and requested to work with me specifically.

On paper, this was exactly the kind of inbound I’d been building toward. International startups. Technical founders. Complex go-to-market challenges. The kind of work where an operator with a background in strategy, people systems, and organizational design should be able to add real value.

There was just one problem. The startups were:

1. A space laser communications company — building satellite-to-ground optical links for defense and commercial applications.

2. A biomedical tissue testing startup — developing next-generation tissue analysis platforms for clinical diagnostics.

Space lasers and tissue samples.

Not exactly the domains where “I’ve redesigned org charts and integrated workforces across hedge funds and industrials” lands with any authority.

What I Told Myself

Here’s the dangerous part. I didn’t immediately recognize the mismatch. And the reason I didn’t is worth examining, because it’s the same trap that portfolio career advocates, myself included, don’t talk about enough.

I told myself a story. It went like this:

“Strategy is strategy. Organizational design is organizational design. I’ve advised 9+ CEOs across wildly different industries. My value isn’t domain expertise — it’s operational pattern recognition. I can help any technical founder translate complexity into clarity. That’s literally my tagline.”

And that story isn’t entirely wrong. It’s just dangerously incomplete.

Because there’s a difference between transferable skills and transferable credibility. I had the first. But I did not have the second.

The Pitch

I prepared the way I always do. I studied both companies. I mapped their organizational challenges: hiring for niche technical roles in the US, navigating regulatory environments, structuring their first American teams. I built frameworks. I drew on parallels from my M&A integration work and startup advisory experience.

The space laser company needed help positioning their technology for US defense procurement channels while simultaneously building a commercial sales pipeline. They had a brilliant team of engineers and a founder who could explain photon propagation through atmospheric turbulence but couldn’t articulate why a Series A investor should care.

The tissue testing company needed to navigate FDA regulatory pathways while scaling their lab operations and hiring their first US-based clinical team. Their science was cutting-edge — the kind of work that could genuinely change diagnostic outcomes — but their go-to-market strategy was a whiteboard sketch and a prayer.

In both cases, I could see the organizational problems clearly. The space company had a classic technical-founder communication gap. The biomedical company had a sequencing problem — trying to hire before they had regulatory clarity, which meant they’d burn cash building a team that might need to be restructured six months later depending on which FDA pathway they pursued.

I wrote the decks. I had the calls. I pitched.

And I lost. Both of them.

What Actually Went Wrong

Let me be precise about this, because “I lost the pitch” is not the lesson. Losing pitches is normal. The lesson is why I lost, and why I should have seen it coming.

Problem 1: Domain credibility gap.

When the space laser founder asked me, “Have you worked with any defense-adjacent startups navigating ITAR compliance?” the honest answer was no. When the biomedical founder asked, “Do you understand the difference between a 510(k) and a De Novo pathway?” the honest answer was that I’d Googled it the night before.

My operational frameworks were sound. My strategic instincts were correct — I later learned that the tissue testing company did, in fact, restructure their plan almost exactly along the lines I’d suggested. But in the room, credibility is not measured by whether your advice turns out to be right. It’s measured by whether the founder trusts you enough to follow it. And trust, in deep-tech verticals, is built on demonstrated domain fluency. Not “I can learn this quickly.” Demonstrated.

I was asking founders to bet their runway on a strategist who had never operated in their sector. That’s a concentration of trust risk that no amount of general competence offsets.

Problem 2: The portfolio career identity confused the signal.

This one stung a little bit more. When I explained my background — hedge funds, industrial workforce integrations, startup advisory, Substack newsletter, mentoring through Oxford Entrepreneurs and CamEntrepreneurs— I watched it land differently than I expected.

In my world, that range signals versatility and pattern recognition. To a deep-tech founder in South Korea or Taiwan evaluating whether to spend their limited budget on a fractional advisor, it signaled something else entirely: “This person does a lot of things. Which means they probably don’t do my thing.”

The portfolio career thesis works. But it has a shadow side that I’ve been slow to write about. When your professional identity spans too many lanes, each individual lane looks thinner. The very diversification that protects you in aggregate can undermine you in any specific pitch.

I call it portfolio blur: the moment when your range becomes illegible to the person evaluating you for a specific job.

Problem 3: I was optimizing for optionality, not fit.

I took the meetings because they were inbound. Because Plug and Play is a credible platform and the introduction felt like a form of validation. Because saying yes to a space laser company sounds interesting at a dinner party. Because my calendar had some room. Because the portfolio career playbook says: explore adjacent opportunities: you never know which one compounds.

All true. All dangerous when taken as operating instructions without a filter.

The filter I was missing was simple: “Is the gap between my current credibility and this client’s required trust level closeable in the sales cycle?”

For the space laser company, the answer was no. Defense procurement expertise takes years to build. No framework deck was going to bridge that gap in a 45-minute call.

For the tissue testing company, the answer was maybe — if I’d partnered with someone who had FDA regulatory experience and positioned myself as the organizational layer on top of their domain expertise. I didn’t think to do that in time. I pitched solo, and I pitched as a generalist into a specialist’s buying decision.

The Financial Metaphor

In portfolio theory, diversification reduces risk. But there’s a concept called the diversification discount — the empirical finding that conglomerates often trade at lower valuations than the sum of their parts. Investors penalize companies that operate in too many unrelated businesses because the complexity makes it harder to evaluate what the company is actually good at.

The same discount applies to portfolio careers. If your professional identity spans hedge funds, startups, workforce design, newsletters, mentoring, and consulting — each of those is real, but the aggregate can trade at a discount in any individual market.

The founders from Plug and Play weren’t evaluating my portfolio. They were evaluating a single position: “Is this person the right fractional advisor for my specific, highly technical, heavily regulated startup?”

And my portfolio, in that context, was noise.

What I’d Do Differently

Three things:

1. Apply the “credibility close” test before taking the meeting.

Before I pitch, I now ask: can I demonstrate domain-relevant credibility within the first ten minutes of this conversation — not through frameworks, but through specific experience, relationships, or outcomes in this sector? If the answer is no, I either partner with someone who can, or I pass.

This is the portfolio career equivalent of position sizing. Not every opportunity deserves an allocation. Some positions are too far from your core competence to generate alpha, no matter how interesting they look.

2. Separate curiosity from capability.

Space lasers are fascinating. I genuinely enjoyed learning about satellite-to-ground optical communication and the engineering challenges of atmospheric interference. That curiosity is an asset: it’s part of what makes me a good strategist across sectors. But curiosity is not a service offering. The fact that I find your industry interesting does not mean I can serve your company well. Those are different things, and conflating them is how portfolio careers slide into overextension. I’ve since outlined my offering in a presentation on my website.

3. Name the domain gap out loud — before the client does.

The worst moment in both pitches was when the domain credibility question came up and I was on my back foot. If I’d opened with, “I want to be transparent — my operational background is in workforce design, M&A integration, venture fundraising, and startup scaling. I don’t have deep-tech defense experience, and here’s specifically how I’d bridge that gap for your company...” the conversation would have been different. Maybe they’d still have said no. But I’d have controlled the narrative instead of losing it.

Narrative control, as I’ve written before, is a career moat. I forgot to apply my own framework…

The Broader Lesson

I believe in portfolio careers. I believe that diversification across roles, income streams, and professional identities is the rational response to a labor market where AI is automating certainty and single-employer loyalty is a concentration risk.

But diversification has a failure mode, and it’s this: you spread so wide that you become illegible. Your range, which protects you in aggregate, costs you credibility in the specific. You say yes to things that are adjacent to your competence but outside your demonstrated authority. And you confuse optionality, which is the ability to move laterally, with capability, which is the ability to deliver for the client.

The space laser company eventually realized they weren’t ready to scale to the United States. The tissue testing company brought on an advisor with a regulatory affairs background from a major diagnostics firm. Both made the right call. And I made the right call, eventually, by recognizing what happened and recalibrating.

A portfolio career is not an invitation to do everything. It’s a framework for doing the right things — the things where your credibility, capability, and curiosity align — and having the discipline to pass on the rest, even when the rest involves space lasers.

Especially when it involves space lasers.
