If you can offer staff engagement and volunteering opportunities that are aimed at connecting a company and their employees to your community of followers, programs and events, then they will be delving into their HR (human resources) budget.
If it is appropriate for your organisation to approach a company for corporate social responsibility (CSR) investment (this is where a company recognises that their activities have a wider impact on the society/environment in which they operate) these funds will be siphoned from their CSR budget. This is a growing area in Australia and New Zealand which is great!
Philanthropy can be derived from a number of areas including the marketing budget, a dedicated trust or foundation, discretionary funds, or there can be a specific budget dedicated to donations.
Despite how you choose to diversify your income streams, the one must-do is to plan your strategy internally first, gain the vital buy-in from your Board and CEO and plan your attack strategically. Research where the low-hanging fruit lies, what your mid-term activities will involve and how your long term plans will be supported.
And always make the time to build relationships first.
Strong relationships last.
