CrossPollinators helps the world connect with community organizations. It's largely populated with Bay Area groups so far; you can search by category, find community events, volunteer or collaboration opportunities, etc. Their weekly newsletter is an inspiring summary of Bay Area front line related events.
Crystal and team have gone about designing it with a more stakeholder-engaged process than how most tech companies go about designing comm tools. The platform stems from her work in solar and experiencing a company thinking about how to get low income and working class families to care about climate change, without them being in the room. XPollinators is a beautifully engineered thing, by real communities, and this is just the beginning. <3
