What do you envision the solution looking like? A list of projects, with their updated runway, yearly budget, technology category and subcategory? Maybe create a watch list too and send notifications when the combination of their runway, yearly budget, and rate of donations reaches a critical point of becoming unsustainable. You can also have people give a range of what they'd be comfortable donating. When the project comes to a critical point, the first line of defense is to send notifications to larger businesses and as a project becomes more in danger the notifications get sent down the line to the people whom have smaller budgets.
