2. Business side
• Raised $250,000 by pitching our business strategy to a lot of potential investors and increased our exposure by attending multiple startup conferences and events

• Validated our business idea by discussing with NGOs around the country and identifying the problem they actually had, and that the problem is painful enough that they were willing to pay to solve it

• Validated the MVP by helping an NGO raise over $130,000 at a charity event through our platform

I've been able to raise several investments, both from EU and private investors. I've managed to get our project listed on exchanges, increased the community of supporters for the humanitarian fundraising platform and blockchain.

I've been managing the content creation for our blog (, assuring constant communication with our supporters, mainly using twitter and telegram in order to distribute our blog posts.
I've also been working on NGO partnerships and other important business connections, pitching our project at networking events. I've implemented the concepts from Lean Startup by using short development cycles in order to get validated learning. By having lots of discussions with our customers (NGOs and companies interested in CSR) we're building the product based on their needs and feedback.
