What RareSkills does
RareSkills is a private, bootstrapped Web3 education company founded in 2022 and domiciled in Henderson, Nevada (RareSkills LLC). The company operates an education platform that trains senior software engineers and security researchers in advanced blockchain development, with a curriculum spanning Solidity, Zero Knowledge proofs (Groth16, Circom, Bulletproofs, NTT), Rust, Uniswap V3 concentrated liquidity, and smart contract security topics including invariant testing. The platform combines paid cohort-based bootcamps with a substantial library of free technical content (the ZK Book, the Ultimate Solidity Course, 60 Days of Solana, and 700+ exercises) that functions as a top-of-funnel lead generation asset and a de facto community reference standard. Bootcamps are delivered in 3- to 14-week instructor-led formats priced at approximately $3,000 upfront or ~$1,125 per month on installments, with a 14-day full refund window.
The go-to-market motion is content-first and community-driven: free resources attract senior engineers and auditors from organizations including Ethereum Foundation, Chainlink Labs, Lido, Matter Labs (zkSync), Consensys, OpenZeppelin, Coinbase, and over 60 other Web3 employers; this organic funnel converts into paid bootcamp applications. The company supplements core tuition revenue with bespoke enterprise engineering training, a subscription-based Rust exercise product (RareCode), and the RareTalent job platform that connects alumni to hiring companies. Strategic ecosystem partnerships — including a Solana Foundation grant for the 60 Days of Solana tutorial and co-marketing arrangements with Base (Coinbase L2) and Monad — embed RareSkills across multiple L1/L2 communities. The team is small (11-50 employees), founder/instructor-led (Jeffrey Scholz, João Paulo Morais, Daniel Cumming), and self-funded through tuition, with no disclosed external institutional investment.

Revenue model
- Cohort-Based Bootcamp Tuition: RareSkills generates primary revenue through paid cohort-based bootcamps where students pay tuition upfront or via monthly installments. Bootcamps are instructor-led over multi-week periods (3-14 weeks) with live sessions, community access, and structured curriculum. Engineering teams from companies like Chainlink and Lido use these courses to train engineers.
- Free Content and Community: Free blog articles, tutorials, exercises, the ZK Book, Solidity course, and Solana tutorial serve as top-of-funnel lead generation. These resources build brand authority and trust, driving applications to paid bootcamps. RareTalent provides a secondary revenue-adjacent function connecting graduates with hiring companies.
