Out of this lot I am particularly keen to see someone try legacy fundraising. There's a lot of money there that anecdotally is given away without a lot of research at the moment.

It requires a particular skill set though - in particular great social skills with people over 70. I expect I wouldn't be a good fit for this!

Have you considered emulating this, but for effective charities?

You could try to take the birthday fundraisers in this direction, turning them into a scalable process.

One value adding activity which Charity Science feels well placed to carry out would be putting together the sort of promotional packs which charities with larger fundraising budgets do to support sponsored events, but which most charities favoured within the Effective Altruism movement don't.

I found it difficult to find a simple introduction to SCI and the work they did when I was pitching it as a charity for my work's annual charity auction. (NB: Materials seem to have improved since I did this - http://www3.imperial.ac.uk/schisto/whatwedo Opportunity may well remain, within and beyond SCI)

Register the business on fundraising platforms and inspire employees to donate for charity.

Also, does anyone know anyone with experience in fundraising? If so we'd love to be put in touch with them.
