blockchain Startups

Datcroft Games, founded in 2004 by Sergei Shalom, is a game development company that generated eight-figure revenue in 2016 from selling virtual goods across multiple games including Fragoria, an MMORPG with millions of users. The company pivoted to blockchain and crypto in 2017, launching a successful ICO called Mobile Go that raised $53 million (the fourth largest crowdsale at the time), with plans to build a Game Credit Store to provide developers 90% revenue share versus Apple/Google's 70%.

Christoph Jentzsch, a theoretical physicist and early Ethereum contributor, co-founded Sloc.it in 2015 to enable decentralized sharing economy through blockchain and IoT integration. After learning hard lessons from the failed DAO project, he pivoted to building software that sits on top of IoT devices (like smart locks and EV charging stations), allowing asset owners to receive payments via smart contracts. The company raised $2M in seed funding in early 2017 and deployed its solution on over 1,000 EV charging stations.

BigchainDB, founded by Bruce Poon, is a blockchain database platform designed to handle data-driven enterprise use cases that Bitcoin and Ethereum cannot efficiently support. Currently serving 5-10 customers at $5-10k/month with $50-60k MRR (targeting $100k by year-end), the company has raised $6 million and employs 20 people (mostly PhDs) to solve supply chain tracking, regulatory compliance, and data provenance problems across industries like pharmaceuticals, energy, and automotive.

Zcash is a privacy-focused cryptocurrency that adds enhanced data security to Bitcoin by protecting transaction confidentiality and preventing pattern analysis. Founded by Zouko Wilcoxie, it raised $3 million from Silicon Valley angels and launched as an independent blockchain in October 2016, quickly achieving global adoption with daily transaction volumes around $20 million across 15-20 international exchanges. The project has gained significant traction through mining accessibility worldwide and strategic partnerships including JP Morgan's blockchain security solution.

Ripple is an enterprise blockchain solution for global payments, founded by early Bitcoin advocates who pivoted from pure cryptocurrency to practical financial interoperability. Led by Stefan Thomas (CTO and early team member), Ripple has raised $94 million and grown to 170+ people, positioning itself as the "Zapier for global payments" by enabling banks and payment providers to interoperate seamlessly.

Rwango is a proximity marketing SaaS company founded in 2014 that uses Wi-Fi and Bluetooth beacons to help retailers send targeted marketing messages to nearby customers. The bootstrap startup has deployed across 500 retail locations worldwide, generating approximately $15,000 MRR with a pay-per-location ($25-30/month) business model. With zero churn and only a 7-person team based in India, Rwango is exploring blockchain integration and expanding into logistics and apparel tracking.

Bindle is a digital credential wallet that converts health records into non-fungible tokens, allowing venues and events to verify vaccination status and test results without accessing sensitive medical data.

Operating at a usage-based model charging 10 cents per scan, Bindle generates approximately $400-500 monthly in revenue while competing against larger players like Clear and IBM.
