Starknet Foundation (@StarknetFndn): Web3 products solving real-world problems, with real users and real revenue (Part 1)

Web3 products solving real-world problems, with real users and real revenue (Part 1) Crypto doesn’t need new products simply because blockchain exists; it needs more products that require blockchain to exist. This thesis is at the core of the Starknet Foundation. We aren’t here to push blockchain for the hype. We’re here to support builders in creating what matters most: products where decentralization, transparency, and permissionlessness are essential features. We observed a recurring pattern at our @Xfounders_Camp Starknet Bootcamp in El Salvador, a concentrated launchpad for a new wave of builders. Founders solving real problems across payments, compute, gaming, and mining; bringing real users for their products. If you’re seeking inspiration for what such products look like, here’s a glimpse. AirBTC: Book rentals peer-to-peer with Bitcoin @AirBTConline is a Bitcoin-native short-term rental platform designed specifically for the global Bitcoin community. The platform connects travelers and hosts, enabling peer-to-peer bookings that are settled entirely in Bitcoin, eliminating fiat rails and aligning with decentralized, self-sovereign principles. The platform caters to a growing cohort of digital nomads and travelers aligned with the ethos of decentralization. The product already boasts ~500 rentals globally and has over 3000+ users. Their product also generates a monthly revenue of over $10,000 in their MVP stage. CIRO AI Labs: Turns organizational noise into instant, actionable clarity @cirabs context-extraction engine distills streams of information into real-time guidance, so teams anywhere can see what matters, decide faster, and keep momentum all without changing the tools they already use. What makes CIRO different is its verifiable compute backbone, CIRO Network: a distributed GPU marketplace where every AI inference or training job is sealed with a zero-knowledge proof and anchored on Starknet. This cryptographic stamp confirms that the computation ran exactly as specified without exposing any underlying data so enterprises can trust the results, meet SOC 2-grade compliance, and pay only for work that is mathematically proven correct. At the same time, organizations and independent operators can stake spare GPU capacity to the network and earn rewards for powering its 99.9%-uptime, industrial-grade infrastructure. In short, CIRO turns AI compute itself—rather than raw machine data—into a verifiable, token-incentivized asset. In their beta stage, CIRO has already integrated their solution with 5 enterprise customers, and $17k in monthly revenue (expected to grow to $100k by September 2025). Everminer: Access to life-time Bitcoin mining @everminer_io provides lifetime access to Bitcoin mining through a straightforward, prepaid model. Each Everhash—representing 1 TH/s of hashrate—offers continuous Bitcoin payouts without recurring costs. The upfront fee includes energy, hosting, and maintenance, removing the volatility typically associated with mining operations. Everminer operates across the United States, Ethiopia, and Paraguay. In its first year alone, the platform attracted over 4,000 registered users and generated more than $1M in revenue, providing uninterrupted, stable hashrate with no operational costs - delivering a continuous stream of Bitcoin. K1 Technology: ATMs that take cash to give Bitcoin @k1elsalvador is an El Salvador-based startup manufacturing and distributing compact, cash-enabled Bitcoin ATMs. K1 manufactures and sells two models: K1 Mini ($1,200): Coin-operated, basic Lightning ATM. K1 Plus ($1,850): Accepts both bills and coins, supports multiple currencies, includes display ads. The project is designed specifically for unbanked and underbanked populations. Operating on the Lightning Network, these ATMs allow users to purchase Bitcoin with cash. They have already sold 110+ units sold across 23 countries, including the U.S., Canada, Germany, Japan, South Africa, and Australia. You’ve just met the first wave of builders currently at the XFounders Starknet Bootcamp. We’ll introduce the next set of builders soon. Keep an eye out!
