It really depends which segment in healthcare you're looking at and what stage the company is at.
Since you're based in Madrid, a good place to start this year would be the Digital Health & Wellness summit at the Mobile World Congress in Barcelona (24th Feb). I know that there will be investors at this session and pitches from entrepreneurs. It will also give you an opportunity to meet people who have experience with EU funding (H2020, AAL-JP, IMI etc) if you are looking for public-private partnerships.
For Series A funding and mid-stage companies I would try Health Tech summit hosted by e-unlimited:
Although the next one is in June it's definitely worth going to (both as a novice investor and entrepreneur)
For later stage companies try this one (investors likely to be family offices)
if you are interested in connect on LinkedIn, I do the same but specifically for impact investing and elderly care startups.
