Where to find fintech, climatech or legal/insurance AI start ups in London? (I will not promote)

Hi everyone, I thought I’d try my luck and see if anyone has any pointers of where to maybe look. I’m wanting to move to London to be closer to my partner, and would prefer to continue working in a start-up environment but this time in a field I’m interested in. For a bit of background, I graduated in 2024 with a degree in Law with International Legal Studies and for the last six months have been working in sales having brought a medical product range to market and getting it set up across the EMEA market. In addition, I’ve recently been attempting to get into SaaS sales as well, so have expanded my remit into a fertility software that I’ve been pitching to clinics across the UK. Before that, I worked in hospitality and briefly ran my own events company at university. I’ve really enjoyed the intersection between sales, analytics and strategy and is something I’d like to continue doing. I feel like whilst I’m young, now’s the time to really burn the midnight oil and jump into something fast and exciting in something I’m passionate about which is why I’m targeting fintechs, climatech or legal/insurance AI. I suppose really would it be doable? My primary experience has been sales based in medical products, the nightlife industry (so B2B and B2C) and recently a little SaaS. I’m not too sure how to market that to fintech, climatech or AI startups, or even if my background would get a look at. So far I’ve looked at: A) LinkedIn (although finding the right kind of opportunities has been difficult) B) Built in London C) Index Ventures Is there anywhere else I should be looking? What else can I do to optimise my chances? Thanks in advance :)
