About

Building a startup can feel overwhelming when every decision appears urgent: validating the market, defining the product, finding customers, building a team and preparing for investment.

I help early-stage founders identify what matters most, challenge assumptions and turn uncertainty into a clear and actionable strategy.

Over the past 8+ years, I have built and led ventures at the intersection of technology, health, education and culture. Alongside my work as a founder and operator, I mentor entrepreneurs, advise startups and evaluate investment opportunities as an angel investor.

My experience combines the founder, operator, mentor and investor perspectives. I have launched and developed ventures including Clynx, Lampsy and Gleedot, worked with founders across multiple industries, supported startup and innovation programmes, and assessed early-stage companies through angel-investment networks.

I can support you with:

– Market and problem validation
– Business model and positioning
– Go-to-market strategy
– Product and growth priorities
– Pitch decks and investor storytelling
– Fundraising strategy and investor readiness
– Founder decision-making and accountability

My mentoring style is practical, direct and highly personalised. I will not simply agree with your ideas—I will help you test them, identify blind spots and leave each session with clear next steps.

This mentorship is particularly relevant for first-time founders, early-stage teams and professionals transitioning into entrepreneurship.

What mentees say

5 out of 5 stars

Joana was fantastic, helping me find the best choices to make to start producing social media growth in combination with a strategy for how to convert that attention to users. She was very helpful in finding solutions but also in exploring where I was and wanted to go in our sessions.

Joana was the perfect mentor for my stage of entrepreneurship. She consistently pushed back on my assumptions in a gentle but firm manner, which made a real difference. Compared to my previous product ideas, I honed in on something people cared about much more quickly. One example: I pitched an idea and described my small set of beta users who were willing to test it. Joana encouraged me to talk to at least 10 users first. After those conversations, I landed on an idea with significantly more market pull—evidenced by the fact that several players were already in the space, whereas my original idea had none. I would hire Joana again without hesitation.
