Oliver KicksOur advice for fundraising Pre-seed is to focus on what makes your founding team’s skillset and collective experience an ‘unfair advantage’. Many funds are looking earlier in company lifecycles due to adverse later-stage conditions, so use this opportunity to build an exciting narrative backed by some early validation from users or customers.

Jonny SeamanThe best advice I can give to founders looking to raise investment is to 1) target the right investors who know your industry, 2) approach them in a personalised way and 3) put yourself in their shoes.
Think about what you’d want to see if you were to invest in a company. Would you reply to an email that looked like a generic copy-and-paste? Would you feel comfortable investing your money into a company in a sector you know nothing about?
Be specific about which investors you approach and how you approach them, and trust that you’ll align with the right ones.
