Services

NFT Demon Holdings LLC offers consulting, advisory, and bespoke custom application development across blockchain, artificial intelligence, and quantum computing. Every engagement is led personally by founder Jeremy Ryan.

Blockchain & Web3

Blockchain Consulting

Bespoke blockchain solutions and end-to-end strategy: custom chain integrations, smart-contract architecture, tokenization of real-world assets, wallet and exchange integrations, and Web3 product builds — plus tokenomics, community architecture, influencer (KOL) campaigns, and press strategy. This goes well beyond memecoins and NFT drops: Jeremy built the largest NFT operation on BNB Chain and has consulted for Fortune 500 companies, celebrities, and governments on blockchain integration.

Artificial Intelligence

AI Consulting & Custom AI Applications

Practical AI adoption: identifying where AI actually pays off in your operation, then building the bespoke tools to do it — automation pipelines, AI-integrated internal tools, and customer-facing applications. We build what off-the-shelf products can't.

Quantum Computing

Quantum-Readiness Advisory

The quantum threat to elliptic-curve cryptography is a when, not an if. We advise wallets, exchanges, custodians, and funds on post-quantum migration strategy — including solutions that quantum-proof assets at the wallet or exchange level with no separate blockchain and no per-transaction fees.

Bespoke Development

Bespoke Custom Applications

When the use case is genuinely new, the software doesn't exist yet. NFT Demon Holdings designs and delivers custom applications across blockchain, AI, and quantum-adjacent domains — scoped tightly, built to ship, and owned by you.

How engagements work

Simple, direct, and sized to the problem.

1 · Discovery call

A direct conversation with Jeremy about what you're trying to do, what's blocking it, and whether we're the right fit. No account managers, no layers.

2 · Scoped proposal

A fixed-scope engagement — advisory sprint, retained advisory, or a full custom build — with deliverables and timeline in writing.

3 · Ship & support

Delivery with documentation and handover. Ongoing advisory retainers available for teams that want continued access.
