Blockchain Business.

BRNZ builds revenue-ready blockchain businesses with crypto payments, NFT monetization, token-gated access, and multi-chain wallets. Six networks. $0 upfront. You bring the demand. We build the company.

The Problem

Everyone Wants a
Blockchain Business.
Almost Nobody Can Build One.

560 million people own crypto. The market is $5B and growing 43% annually. But turning a blockchain idea into a real, revenue-generating business? That's where founders get stuck.

External Problem
⚡

The Tech Is Brutal

Six major chains. Different wallet standards, signing mechanisms, token formats, RPC endpoints. Building on Ethereum doesn't mean you can build on Solana. Every chain is a separate engineering project — and hiring blockchain developers costs $200K+ per year.

Internal Problem
😰

You're a Founder, Not a Chain Architect

You know your market. You know your customers. But which chain do you bet on? How do you accept crypto AND credit cards? How do you gate content with NFTs without alienating non-crypto users? The gap between "blockchain idea" and "blockchain revenue" feels enormous.

Philosophical Problem
🔒

Great Ideas Deserve Great Execution

The next wave of Web3 businesses will be built by domain experts with real customers, not by crypto-native devs guessing at product-market fit. Your expertise is the product. Blockchain is the infrastructure. You shouldn't need to become both.

The Guide

We Build the Business.
You Lead the Market.

We've seen what doesn't work

  • ♡ Founders burning 6 months and $200K building blockchain features that a production platform already provides
  • ♡ Vibe-coded smart contracts going to production with critical vulnerabilities, because nobody ran a security scan
  • ♡ Projects betting on one chain, then watching users migrate to another, with no way to follow
  • ♡ Beautiful blockchain prototypes that never generate a dollar because the commerce layer was an afterthought

Here's why we build differently

  • ◆ BRNZ delivers complete businesses, not just technology, commerce, payments, user management, and blockchain integrated from day one
  • ◆ Multi-chain from the start: Ethereum, Solana, Polygon, Cardano, Stacks, and Base, switch or expand without rewriting code
  • ◆ ODIN (our AI builder) deploys secure blockchain features in weeks. Kensai (our security scanner) audits every deployment before it ships
  • ◆ Equity partnership: $0 upfront, 33% equity, both sides incentivized to make the business succeed
  • ◆ 20+ years in technology. Real portfolio companies with real revenue. Not our first cycle. Not our first chain.
How We Build

Your Blockchain Business.
In Three Phases.

We do not ask you to learn Solidity or assemble a blockchain team. BRNZ builds the business, ODIN ships the product, Kensai audits the security, and you own the result.

01
🏗️

Foundation

We build your blockchain-enabled platform: multi-chain wallet authentication, customer identity, and commerce infrastructure. Users connect MetaMask, Phantom, Nami, verified with cryptographic signatures.

  • Multi-chain wallet integration (6 networks)
  • Signature-based user verification
  • Unified customer identity across chains
  • E-commerce with crypto + fiat payments
  • Security audit via Kensai before launch
02
💰

Monetization

We wire the revenue streams: crypto payments alongside Stripe and PayPal, NFT subscription tiers, token-gated premium access, and Wert fiat onramp so non-crypto users can buy with credit cards.

  • Native crypto payments (ETH, SOL, MATIC, ADA)
  • Credit card → NFT via Wert + NFTPay
  • NFT-based subscription plans
  • Token-gated content and features
  • Cashback and loyalty rewards
03
🚀

Growth

We build the growth engine: Merkle tree airdrops to thousands, blockchain event indexing, holder notification campaigns across 15+ messaging channels, and cross-chain portfolio dashboards.

  • Merkle tree airdrops (900K+ addresses)
  • Token holder notifications (Telegram, Discord, etc.)
  • On-chain data indexing and event monitoring
  • Cross-chain portfolio tracking
  • Multi-channel engagement automation

The Old Way

  • Hire Solidity, Rust, infra engineers
  • 6 to 12 months before first transaction
  • $200K to $500K burned before revenue
  • Locked into one chain
  • No security audit budget
  • Commerce integration? Another 3 months
  • Customer engagement? Build it yourself
→

The BRNZ Way

  • ODIN builds it, AI-first, zero dev bottleneck
  • Revenue in weeks, not months
  • $0 upfront, equity partnership
  • 6 chains from day one
  • Kensai security audit on every deployment
  • Commerce, payments, subscriptions built-in
  • 15+ messaging channels ready to deploy

Business Models

Blockchain Businesses
We Build.

Not theoretical use cases. Real business models BRNZ deploys, with built-in revenue, security, and multi-chain infrastructure.

Commerce

Crypto-Enabled E-Commerce

A complete storefront accepting crypto and fiat simultaneously. Products, orders, inventory, discounts, with native ETH, SOL, MATIC, ADA payments alongside Stripe and PayPal.

Founder Story

Crypto + StripeWert onrampMulti-chain
Membership

NFT-Gated Membership Platform

Membership passes are NFTs, owned, tradeable, verifiable on-chain. Replace SaaS subscriptions with one-time sales plus secondary royalties. Members own their access forever.

Founder Story

"SaaS subscriptions create churn. NFT memberships give members ownership and me royalties on every resale."

NFT PlansToken-gated accessERC-721
Creator Economy

Token-Gated Content Business

Premium courses and content gated behind token ownership. Automatic verification. Non-holders get a purchase flow. Credit card buyers get NFTs minted via Wert, zero crypto knowledge needed.

Founder Story

"Token gating gives me exclusivity without login walls. Wert means non-crypto buyers can still get in with a credit card."

Token-gated accessWert + NFTPayDigital delivery
Loyalty

Token-Based Loyalty Business

Rewards are on-chain tokens with real value. Top customers get NFT airdrops. VIP status is verifiable and tradeable. Merkle distribution + leaderboard gamification for viral engagement.

  • 6 to 12 months before first on-chain transaction
  • Locked into one chain
  • No fiat onramp, 90% of customers can't buy
  • Unaudited contracts, one exploit from damage
  • Commerce bolted on as an afterthought
  • Every dollar on infra = a dollar not on growth

Let BRNZ Build It

  • ODIN builds it, AI-first, 85%+ gross margins
  • Revenue in weeks, not months
  • $0 upfront, 33% equity, aligned incentives
  • 6 chains from day one
  • Wert + NFTPay: card to NFT, 198 countries
  • Kensai audits every deployment
  • Commerce, payments, messaging, integrated from launch
