16NOVCommunity & NetworkingWomen's HealthMembersInvesting in women’s health – a Nordic Agenda for growth, equality and resilience09:00–11:00 · TalentGarden, Danneskiold-Samsøes Allé 41, 1434 København

How do we turn ambitions into concrete solutions and ensure that more women benefit from the latest knowledge, timely diagnostics and equal access to treatment?

Why attend?
Investing in women’s health can improve quality of life, strengthen workforce participation and create value for both society and the economy. Yet significant challenges remain: women live longer than men but spend 25% more of their lives in poor health (World Economic Forum and McKinsey Health Institute, 2024). The event discusses how the Nordic countries can translate knowledge and evidence into better treatment options, stronger clinical guidelines and concrete policy initiatives.

Who is it for?
Hub members working with women’s health and femtech.
Politicians, patient representatives, researchers and healthcare leaders will be in the room.

Who’s behind it?
Health Tech Hub, DI – Confederation of Danish Industry, Roche, AbbVie, Novartis and Sanofi host this side event to the Copenhagen Summit for Gender Equality and Women’s and Girls’ Rights, convened by the Nordic ministers for gender equality.

Arrival and registration is from 08:30.

18NOVCommunity & NetworkingInvestment & FundingInvestorsMembersNew Nordics Healthtech Matchmaking at SlushHelsinki

Join us where Slush’ health tech investors actually gather


Slush pulls in around 13,000 founders and investors, and it’s among the largest concentrations of venture capital anywhere – roughly one VC for every two founders in the room. But with 6,000+ startups also attending, reaching the investors most relevant to you is its own challenge.

Why attend
This is one of the very few health tech-focused side events at Slush, and that’s exactly what makes it worth your time: it draws the majority of the city’s health tech investors into a single room. Last year it brought together almost 300 attendees, including around 150 investors – and this year is set to be even bigger. We’ll be there in person to help make the introductions, so you’re not navigating the room alone.

Who it’s for
Health tech startups attending Slush, or considering it, who want direct access to investors focused on the sector rather than the wider 6,000-startup crowd.

Format
A matchmaking side event on day one of Slush (18 November).

Join us
A limited number of booths are available for members, spots are competitive – apply to Nicolas Bouchet by Friday 2 October.

25NOVHealthcare CatalystMembersHealthcare Catalyst: Direct access to six healthcare systems across three continents14:30–16:30 · Online

Healthcare Catalyst: Cross-market edition


Six healthcare systems, three continents, one online afternoon – a shared look at how each approaches innovation, what they need from partners, and where collaboration across borders is actually possible.

Why attend
You’ll hear six providers’ strategic approach to innovation and where they’re looking for partners, put questions to each directly in ask-me-anything breakouts, and – where there’s a genuine fit – get a warm introduction from Health Tech Hub for follow-up after the event.

Who it’s for
Health tech companies looking to understand innovation priorities across healthcare systems in Denmark, France, Germany, Sweden, the UK, and the US.

Format
Fully online and open to all members – just register. Providers share their priorities, followed by a moderated cross-market discussion and ask-me-anything breakouts with each one. Where there’s a genuine fit, Health Tech Hub curates a warm introduction afterwards – not a live 1:1 on the day.

Participating organisations

  • Denmark: Bispebjerg and Frederiksberg Hospital
  • France: Ramsay Santé
  • Germany: Vivantes
  • Sweden: Region Skåne
  • UK: Barts Health NHS Trust

A relaxed thank-you for a strong year, and a good excuse to head into the break well connected.

Kindly hosted by Bech-Bruun.

14JANCommunity & NetworkingHydration & ConversationInvestment & FundingInvestorsMembersOpen EventHydration & Conversation: Ask investors anything15:00–17:00 · Talent Garden, Danneskiold-Samsøes Allé 41, 1434 København

When founders meet investors, it’s usually across a pitch, and everyone is performing a little. This afternoon turns that around. A few investors take the hot seat, and you get to ask the questions.


Why attend?
Some questions never come up in a pitch meeting, because there’s too much riding on it. Here you can ask them openly and hear how investors from hardware and medtech, consumer health and health tech see things differently. And since investors tend to back people they already know, it’s a relaxed way to start those relationships before you need them.

Who can join?
Open to all health tech and medtech founders who are curious about how investors think, whether they’re raising now or laying the groundwork for future fundraising.

What is the format?
It’s a Hydration & Conversation, so it’s informal: drinks in hand, no slides, no script. The afternoon opens with an Ask Me Anything with the investor panel and carries on into networking and conversations in the room. Come for the questions, stay for the drinks.

Who will you meet?
We’re putting together a panel of investors and are aiming for a mix of perspectives across hardware and med-tech, consumer health and health tech. Names will be announced as they’re confirmed.

Hub members and ecosystem partners will be in the room too.

28APRInvestment & FundingMembersOpen EventFunding Bootcamp: How to value your health or medtech startup14:00–17:00 · Talent Garden, Danneskiold-Samsøes Allé 41, 1434 KøbenhavnRead more

You know how much capital you need to raise. But what valuation should you put on your company, and how do you make a credible case for it?


Why attend?
When revenue is limited, clinical evidence is still developing and regulatory milestones lie ahead, valuation can feel more like negotiation than calculation. The session helps you understand what investors look at and how to prepare: what drives valuation before meaningful revenue, how clinical evidence, regulatory progress and commercial traction influence their assessments, and how to build and defend a credible valuation.

Who is it for?
Early-stage health tech and medtech founders preparing to raise capital. Open to members and non-members.

What is the format?
Practical insights and discussion with two early-stage investors, and time to ask questions about your own fundraising challenges, including how to balance capital needs, dilution and expectations for future rounds. The session follows our funding bootcamp on dilution and cap tables.

Who will you meet?
Christoffer Melchior is a DanBAN member and active health business angel. Mathias Brink is a partner and CEO at Delphinus Venture Capital. Both bring perspectives from early-stage health and medtech investing.
