Bitcoin blockchain Startups

Graphite Docs was a privacy-focused, blockchain-based alternative to Google Docs that launched to viral success on Product Hunt and Hacker News in March 2018, reaching $20,000/month in grant funding at its peak. However, founder Justin Hunter made a critical strategic mistake by pivoting from his engaged consumer/blockchain enthusiast user base to pursue a B2B enterprise market where the product's core features (user control, blockchain complexity) were fundamentally misaligned with customer needs. The company ultimately failed and shut down in late 2020 due to lack of product-market fit in the B2B segment and Hunter's inability to adapt despite clear signals that users wanted a consumer product.
