Midlife MavericksYou already have one. You just haven’t called it that yet.
If you’ve spent the last six months telling people “I do a bit of consulting, some advisory work, I’m writing, I’ve got a coaching thing starting,” and then watching their face go slightly blank, congratulations. You’re running a portfolio career. You’ve just been apologising for it instead of owning it.
I hear this every week. Women in their late thirties, forties, early fifties who’ve left corporate or are halfway out the door, and they describe what they’re building with a kind of embarrassed shrug. Like they need to pick one thing and announce it properly before they’re allowed to call themselves professionals again.
They don’t need to pick one thing. They need to understand that the thing they’re already building has a name, a structure, and a growing body of evidence behind it.
What Is a Portfolio Career?
A portfolio career is a working life made up of multiple income streams, roles, and projects rather than a single full-time job with one employer. You might consult, coach, write, advise, speak, sit on advisory boards, or build a product. Some strands are for money. Some are for learning. Some are for creative energy. The mix shifts over time. That’s the point.
The term was first used by Irish management thinker Charles Handy in the 1980s. Handy described a “portfolio work life” as a way to diversify your professional activity the way you’d diversify a financial portfolio: spread the risk, create multiple sources of return, and build resilience against any single point of failure.
What was a thought experiment in 1984 is now the fastest-growing career structure in the knowledge economy.
And it’s not new because someone invented it. It’s new because the old model broke.
How a Portfolio Career Is Different from Freelancing, Fractional, or a Side Hustle
These terms get thrown around interchangeably, and they shouldn’t be.
Freelancing is selling your time and skill on a project-by-project basis to different clients. You do one thing (design, copywriting, development, consulting) for multiple buyers. The work might vary, but the service is usually consistent. Freelancing is a delivery model.
Fractional work is holding a part-time executive or specialist role within someone else’s company. Fractional CMO, fractional CFO, fractional COO. You bring senior capability on a part-time basis. Fractional is a format, and it’s usually one strand of a broader portfolio.
A side hustle is something you do alongside a full-time job, typically for extra income or to test an idea. It exists in the margins. A side hustle is a supplement, not a structure.
A portfolio career is the architecture that holds all of these. It might include a fractional role, a consulting strand, a coaching offer, a writing practice, and an advisory seat. Each element serves a different purpose, earns at a different rate, and uses a different part of your brain. The whole thing is designed to fit the life you want, not the job description someone else wrote.
I wrote about this shift in my newsletter a few months ago, through the story of a man who’d reached the top and realised he didn’t want any job anymore. He didn’t need another title. He needed a different structure. That structure is a portfolio career.
Why Portfolio Careers Are Exploding Right Now
Three things are happening at once.
The career ladder is collapsing. Restructurings, layoffs, flat hierarchies, and AI-driven role elimination mean the old “climb and stay” model is increasingly unreliable. Deloitte’s research on workforce ecosystems shows that organisations are moving away from headcount-based talent models toward networks of employees, contractors, alumni, and ecosystem partners. The stable full-time role with a clear path upward is no longer the default. For many senior professionals, the question isn’t “will I get promoted?” but “will my role still exist in two years?”
AI is making solo operators more capable. A single person with the right skills and the right tools can now do work that used to require a team. Research, content, admin, proposal writing, knowledge management, client communication: AI handles the repetitive layers, which means a portfolio careerist can run multiple strands without needing to hire a department. The barrier to running a complex, multi-strand career has dropped significantly.
Midlife professionals are choosing flexibility over prestige. After twenty years of back-to-back meetings, 6am trains, and collapsing on the sofa at 9pm, a growing number of senior professionals are saying: I want meaningful work, creative variety, and control over my calendar. I don’t want another title. A 2026 salary guide from TMM Recruitment noted the continued rise of portfolio-style working among experienced professionals who value autonomy over organisational belonging.
These three forces are converging. The structure is less stable, the tools are more powerful, and the desire for something different is at an all-time high. Portfolio careers aren’t a trend. They’re the structural response to a labour market that no longer rewards loyalty with security.
What My Portfolio Career Actually Looks Like
I run six interconnected strands.
Capital introduction and advisory. Through Vibe Advisors, I work with early-stage hedge fund managers, helping them raise capital, build investor relationships, and tell their story. Twenty-five years in finance taught me that capital raising is a people business. I bring marketing instincts, AI fluency, and a network that most people in this space don’t have.
Coaching and mentoring. I work with women leaving corporate who want to build businesses from the skills they already have. Skills audits, mentoring, strategic planning. This started as a side project and became a core part of my working identity.
Writing. Two newsletters: Midlife Mavericks (weekly, for women building businesses and portfolio careers from corporate experience) and an Emerging Manager newsletter focused on the hedge fund space. Plus a column for Executiva, a Portuguese publication for corporate women, and content across Substack, Threads, and increasingly LinkedIn. Writing connects everything else. It’s how people find me.
Public speaking. Conferences, panels, podcasts. Speaking is where the coaching and the finance worlds overlap in real time.
Corporate advisory. Advisory roles focused on AI implementation and adoption. A different muscle from the hedge fund work, but built on the same instinct: helping organisations figure out what’s coming and how to move.
Giving back. I mentor younger women and people further behind me on the path. Unpaid, deliberately. In the spirit of sending the elevator back down. This strand doesn’t earn money, but it earns something I value more.
None of these strands alone would be enough. Together, they make a career that fits how I want to live, earns across multiple sources, and uses every part of my brain.
I didn’t plan this from day one. I started with what I knew (capital introduction) and added strands as opportunities and interests emerged. The portfolio wasn’t designed on a whiteboard. It was built by paying attention to what people asked me for and what I kept coming back to.
The Fears You Need to Hear Named
If you’re reading this and thinking “sounds great, but…” let me name the buts. Because they’re real, and pretending otherwise would be patronising.
“But my income won’t be stable.” Correct. Some months are feast, some are famine. I’ve had months where the number made me want to open champagne and months where I questioned every decision I’d made since 2019. Income volatility is the price of autonomy. The antidote is multiple strands, because when one dips, another holds. A single employer feels stable until the reorg email lands. Then you realise your “stability” had a single point of failure.
“But people won’t take me seriously.” This is the “what do you do?” problem. When you can’t answer in one sentence, some people get confused. And confusion, in professional circles, can feel like a loss of status. You’ll need to get comfortable with the fact that not everyone will understand your structure. The people who matter will. Investors and coaching clients don’t care about my job title. They care about whether I can solve their problem.
“But I don’t know where to start.” You start with what you’re already doing. Every portfolio career I’ve seen, mine included, began with one skill that someone was willing to pay for. Then a second strand appeared. Then a third. You don’t design five income streams on a spreadsheet and launch them simultaneously. You build the first one, prove it works, and add from there.
“But I’m too old to reinvent myself.” You’re not reinventing. You’re reconfiguring. Everything you’ve done in your career, every skill, every relationship, every problem you’ve solved, is raw material. A portfolio career doesn’t require you to start from scratch. It requires you to look at what you already have and arrange it differently.
How to Know if a Portfolio Career Fits You
This isn’t a personality quiz. It’s a set of honest questions.
Do you get restless when you’re doing only one thing for too long? Do you have skills that span more than one industry or discipline? Are you already doing unpaid work on the side that feels more like “you” than your day job? Do you value flexibility and creative freedom more than a predictable structure? Have people asked you for advice, expertise, or help outside of your official role?
If you answered yes to most of those, you’re not a generalist. You’re a polymath. And the career structure designed for polymaths is a portfolio.
Herminia Ibarra, an organisational behaviour professor at London Business School, writes about “working identity” as something you discover through experimentation, not introspection. You don’t figure out your portfolio career by thinking about it. You figure it out by testing small bets: a coaching conversation, a consulting project, a piece of writing, an advisory relationship. Each experiment teaches you something about what fits and what doesn’t.
The people who get stuck are the ones waiting for certainty before they start. The people who build successful portfolio careers are the ones who started before they were ready and adjusted as they went.
Frequently Asked Questions About Portfolio Careers
How many income streams do you need for a portfolio career?
There’s no magic number. Most portfolio careerists I know run between three and seven strands. The key is that each one serves a different purpose: some for income, some for learning, some for creative energy. Start with one strand that earns money and build from there.
Can you have a portfolio career while still employed?
Yes, and most people should. Test your first strand as a side project while you still have a salary. A consulting engagement, a coaching conversation, a piece of writing. You don’t need to quit to start building.
Is a portfolio career the same as freelancing?
No. Freelancing is typically one service sold to multiple clients. A portfolio career is an architecture of multiple different roles and income streams. Freelancing might be one strand of your portfolio, but the portfolio itself is broader.
Do portfolio careers pay less than traditional employment?
Not necessarily. Income is less predictable month to month, but many portfolio careerists earn more than they did in corporate roles because they’re pricing on value rather than trading hours for a salary. The trade-off is volatility, not lower earnings.
What skills do you need for a portfolio career?
The skills you already have. Most portfolio careers start with expertise gained in corporate roles: strategy, communication, problem-solving, leadership, industry knowledge. What you add is commercial capability: pricing, pitching, managing your own pipeline, and financial literacy for variable income.
Is a portfolio career risky?
Every career structure has risk. A single employer feels stable until the restructuring email lands. A portfolio career spreads that risk across multiple sources of income, which means no single client or contract can take you down. The risk profile is different, not necessarily higher.
