Janis Pereira — need help with digital, AI & growth?

No big agency. No jargon. No ego. Just a straight-talking expert who's done this for twenty years — who leans on organic channels and free tools to do the heavy lifting, and shows you how to get the most from them. What clients say they love most? They come out of it confident and capable on their own — not dependent on me.

How to bring me in

Three ways this works

Something's up

A focused fix

One thing that's broken, stuck or underperforming — your website, your email marketing, your ads. I'll sort it, or work out what's wrong and tell you exactly what needs doing — and who to get if it's a job for someone else.

Get it going

A project

Something you want up and running but don't know where to start — getting the team confident with AI prompts, moving onto Monday.com, making your own designs in Canva, or launching Instagram ads. I take it from idea to done.

Ongoing

Someone in your corner

Me in the mix a day or two a week, or keeping an eye on your channels in the background. You'll have a trusted pair of hands and senior help — without a senior hire or a long contract.

Where I can help

What's on your plate?

Pick whatever's nagging at you. Everything points at one goal — your business moving forward — and I'll show you how I'd help.

Pick what's on your plate, and see it line up behind one clear goal.

How I'd help

Whatever you pick, I'll show you exactly how I'd help — in plain English — and whether it's a quick fix, a project, or something ongoing.

Hi, I'm Janis

A scientist by background, I've spent 20+ years building growth, digital and marketing across the board, with a strong focus on "tech for good" — health, education and social good.

I've led community for Kahoot! in the early days, launched #1 bestselling children's and YA books for HarperCollins, scaled a global platform for doctors, and helped that tiny business down the road set up their website.

Mostly, I'm the person people call when they want something sorted properly, by someone who'll be straight with them and won't overcomplicate it. And if you'd rather learn to do it yourself, I love helping people build their own skills and confidence, whether that's your whole team or just you.

What's with the North Star?

It's easy to get swept up in shiny AI for its own sake, or to let an expert steer you somewhere that suits them more than you. I've spent decades in "tech for good" — healthcare, education, community, often in regulated, sensitive settings — where we talk about your North Star: the one goal that actually matters.

Every decision, and every ounce of your energy, should keep your North Star in sight and move you towards it. That's how I work — the AI and the technology serve the goal, never the other way around. I set up North Star with that same guiding principle throughout, whether it's growth and digital through North Star Studio, medical education and healthcare AI through North Star Health, or the ideas we prototype together through North Star Labs.

My favourite testimonial

Kind words

If you're in need of remarkable, Janis is who you want by your side. She's a modern thinker in a class all of her own — a whip-smart strategist, a natural intrapreneur, a generous leader, a proper digital savant, an eternal optimist, and a truly awesome human.

I've brought her into 2 companies, both at critical moments of growth, and would jump at the chance to do it again. She thinks at breakneck speed, talks twice as fast, and understands the crazy ebb and flow of modern, digitally-infused culture like no-one.

If you're reading this because of an upcoming opportunity to collaborate with her on something, leap!
