Her Story
About Hillary
I'm a marketing strategist, copywriter, and AI systems builder, which is a fancy way of saying I help people get to the WHY underneath the how.
I actually started my career as a "Brand Therapist," and honestly? I loved it. That title still says everything about how I work. I'm the strategist who isn't satisfied with the surface problem ("we need more content"). I want the real one sitting underneath it ("we can't actually articulate what we stand for"). Get the WHY right, and the how gets a whole lot easier.
I've been at this for over a decade. These days I'm the founder of Syntropy, where we help fractional marketers, fractional CMOs, and micro-agencies trade marketing chaos for systems that actually sound like them. We build custom AI marketing systems, run end-to-end brand audits, spin up founder LinkedIn growth engines, and turn Notion into a real operating system for lean teams. The throughline: AI should be a force multiplier for human creativity, never a replacement for it.
A few other hats. I'm the AI & Automations Lead at The Growth Tribe, where fractional CMOs, agency founders, and senior consultants come to make sense of the tech reshaping our work (together, out loud, minus the hype). Before that I led marketing at Maxitech through a full pivot and brand reposition, and cut my teeth across copy, campaigns, and brand voice at Entrapeer.
Fun factoids: my Master's is in Human Ecology and Sustainability from a university of gastronomic sciences in Italy, after a BA in Sociology and Geography from Vassar. Turns out studying how humans relate to their world is weirdly good training for getting to someone's WHY. I'm also a forager, former sushi chef, and LARPer. Ask me about my Mad Max alter ego...
But back to reality! If you're a fractional marketer or small agency drowning in tools and tabs, and you want a system you actually own (not another dependency), let's talk.
Her Interview
Ten minutes with Hillary
01What do you attribute your success to?
Honestly, stubborn curiosity more than any master plan. I've spent 14 years in marketing, and the throughline isn't one big break, it's that I keep asking "but why does this actually work?" until I understand the system underneath. The other piece is taste: knowing the difference between something that sounds right and something that is right, and refusing to outsource that judgment even when the shortcut is sitting right there. And I'd be lying if I left out the people, the clients who push back, the team who tells me when I'm the bottleneck, the friends who let me think out loud. My version of success has been slow and intentional... and I wouldn't trade the slow part.
02What’s the best career advice you’ve ever received?
Slow is smooth, and smooth is fast. I know, I know, it sounds like a fridge magnet... but it genuinely rewired how I work. Early on I treated speed as the goal: more output, more clients, more everything. The advice that actually stuck was that the quality of your thinking sets the ceiling on the quality of your work, and you can't rush thinking. So now I protect the slow part on purpose.
03What advice would you give to young women entering your industry?
Don't wait to feel ready, and don't perform certainty you don't have. I built a whole voice on saying "I'm torn" and "here's what I'm still figuring out," and it turns out people trust that more, not less. Get genuinely good at one hard thing before you go broad. Be INTENTIONAL about whose advice you actually absorb, because this industry is kind of a soup right now and everyone's shouting. And please, use the new tools, but don't let them think for you. Your judgment, your taste, your weirdly specific perspective, that's the part no machine can copy. Protect it like the asset it is.
04What are the biggest challenges or opportunities in your field right now?
Same answer for both: AI. The challenge is the hype cycle. We're drowning in tools and "agentic everything" and content that all sounds the same. I call it slop, and it's eroding trust faster than people want to admit. The opportunity belongs to whoever's willing to do the unsexy work, the context, the source of truth, the guardrails, so AI actually sounds like you instead of like the internet's average. That's the whole bet I'm making with Syntropy. The teams treating AI as a thinking partner, not a creative vending machine, are going to run circles around the ones racing to publish more, faster.
05What values are most important to you in your work and personal life?
Integrity first, the boring, load-bearing kind. If I can't back a claim with proof, I don't make it. Then curiosity, I want to stay the kind of person who calls the number on the weird flyer just to see what happens. Human-first is the big one: technology should expand what people can do without shrinking their agency, and I think a lot about whether the future we're building actually has room for everyone in it (universal healthcare and cool jumpsuits, ideally). And honestly, warmth. You can be direct and still be kind. I'd rather be both than pick one.
