Bootstrap Scalable Campaigning
Bootstrapping Campaigning Social Media C2C

Scalable Campaigning (needs a better name eventually) is a proposed campaign format that pressures consumer brands to commit to sustainable behavior. Social media users directly reach out to followers of brands with a gap between their green image and reality. Through fun, non-judgmental messaging and links to alternative products, pressure is created where it matters: A company’s fanbase and its bottom line.

Prototyping this case takes a few weeks of part-time work and some volunteers with social media account. We’re terribly excited about this one and happy to help!

Bootstrap Impact 1on1
Bootstrapping Coaching Consulting B2B NGOs

Impact 1on1 is a proposed non-profit coaching and consulting offering to help mission-critical NGO with free-of charge support (consulting, mentoring, hands-on help). Drive this forward. We’re happy to provide access to mentors and coaches for NGOs.

This project needs a pitch, small business case and a well-executed MVP. Want to work on any of these?

Disrupt face-to-face marketing with peer2peer
Bootstrapping Marketing Fundraising B2B2/B2C Business Opportunity

Our project FlyGood enables activists to convince travelers to compensate their flights and receiving a small commission. We’re building a self-sustaining protest-, awareness- and compensation-machine. Why not extend the concept to fundraising in general?

With our help, you can explore and develop a case, non/for-profit to allow everybody to do distributed self-service fundraising. From home or on the streets.

And most importantly, how can we help you fight the climate crisis?
