Last week, I explained why 2025-2030 is the critical window—three convergences creating a once-in-civilization opportunity.

Today I'm going to tell you something that might surprise you:

We're not building infrastructure.

At least, not the way everyone else does.

Let me explain.

Here's how most Web3 projects work:

1. Write a whitepaper about revolutionary infrastructure

2. Raise millions from investors

3. Build the infrastructure in isolation

4. Launch and... pray someone uses it

The result? Ghost towns.

Beautiful protocols with no users. Elegant smart contracts with no transactions. "Infrastructure" that infrastructures nothing.

This is the Cathedral Problem.

You build the cathedral before the congregation arrives. You assume "if you build it, they will come." But they don't come. Because you built what you imagined they needed, not what they actually need.

The blockchain graveyard is full of cathedrals.

We do the opposite.

We don't build infrastructure hoping startups will use it.

We fund startups that must solve real problems—and extract the infrastructure from their solutions.

Read that again. It's the core of everything we do.

Here's how it works:

We select ventures that need to solve hard, concrete problems to survive. Not "exploring blockchain applications." Not "researching potential use cases."

Real companies. Real customers. Real problems.

These builders need backend components to make their products work: identity systems, payment rails, AI agent interfaces, governance mechanisms.

The builders construct those critical components—but to our open standards. They're not building proprietary black boxes. They're building modules that can be extracted and reused.

When a component is battle-tested (used by real users, with real transactions, solving real problems), we extract it. We standardize it. We make it public.

That component becomes part of the 7 Nexi.

This is The Harvest.

Think about how the most important infrastructure actually got built:

Amazon didn't set out to build cloud computing. They needed massive server capacity to sell books. AWS was the harvest—infrastructure extracted from a real business need.

Slack wasn't designed as a communication platform. It was an internal tool for a video game company. The game failed. The chat tool became a $27 billion company.

Stripe emerged because the Collison brothers were tired of the pain of accepting payments for their own projects. The infrastructure came from the frustration.

The pattern is always the same:

Real problem → Custom solution → Extracted infrastructure

Never:

Imagined infrastructure → Hope for adoption → Ghost town

We're applying this pattern systematically to build the 7 Nexi.

Our first cohort—launching Q1 2026—consists of seven "Builder" ventures.

Each has a dual mandate:

1. Commercial success (for investors)

2. Critical code contribution (for the public infrastructure)

I can't reveal specific company names yet. But I can show you the roles:

Seven builders. Seven problems. Seven harvests.

Each venture solves a real market need. Each venture contributes critical code. Each contribution becomes public infrastructure.

Let me walk you through how a Harvest actually happens:

Builders develop their MVPs. They need specific backend components to make their products work.

Example: Builder #2 ("The Foundation") needs a way for AI agents to discover each other and negotiate transactions. That's not a nice-to-have—their entire business model depends on it.

So they build it. A protocol for AI-to-AI commerce. Intent broadcasting. Offer matching. Secure execution.

The component gets used. Real users. Real transactions. Real edge cases.

Every bug found is a bug that won't exist in the public infrastructure. Every edge case handled is a pattern others won't have to solve.

Our technical team audits the code. We standardize interfaces. We document everything.

The AI-to-AI commerce protocol becomes Nexus 7 infrastructure—available for anyone building in the agent economy.

Builder #2 keeps their product. They keep their customers. They keep their competitive advantage in how they use the protocol.

But the protocol itself? Public. Open. Harvested.

Here's where it gets interesting.

Fucina Nexus isn't a dead end. It's a launchpad.

We've designed a "Feeder Orbit" model: startups that prove themselves in our cohort get a fast track to global Web3 accelerator programs. They enter as local builders, they exit as global players.

Think of it as a multi-stage rocket:

Stage 1 (Fucina): 0-to-1. Idea to working product. Local validation.

Stage 2 (Orbit): 1-to-100. Global scale-up. International network. Major investment.

The Feeder Orbit ensures our builders aren't trapped in a regional ecosystem. They're launched into the global one.

And every launch validates our infrastructure. Every success proves the Harvest Model works.

You've heard me use the term "multi-species economy" before. Let me explain why it's central to The Harvest.

We're not just building infrastructure for humans.

We're building for the Intention Economy—the emerging paradigm where AI agents execute complex transactions and negotiate resources on behalf of humans.

This is the transition happening right now:

The infrastructure for the Attention Economy was built by platforms (Facebook, Google, Amazon). They captured the value.

The infrastructure for the Intention Economy is being built now. Who builds it determines who captures the value.

If centralized players build it, we get surveillance monopolies—but for AI agents.

If we build it openly, through The Harvest, we get sovereign infrastructure—where humans AND agents can participate as first-class economic citizens.

This is why The Harvest matters. We're not just building faster or cheaper. We're building differently—with sovereignty baked in from the start.

Now the part you've been waiting for.

Applications for Cohort 1 (Genesis) open January 15, 2026.

We're looking for technical founders who:

• Have a real product idea (B2B or B2C) solving a real problem

• Need to build complex backend components to make it work

• Are willing to build those components to open standards

• Want to be part of infrastructure that serves everyone

Capital: €50K - €150K pre-seed funding

Infrastructure: Your components become part of the 7 Nexi

Governance: $FORGE tokens for contributing to the protocol

Orbit: Fast-track to global accelerator programs

We don't want "blockchain apps." We want founders solving hard problems that require sovereign infrastructure:

• Automating legal compliance for DAOs or remote workers? (Nexus 1)

• Using ZK-proofs for health, financial, or reputation verification? (Nexus 2)

• Building streaming payments or escrow systems for AI agents? (Nexus 4)

• Creating wallets for AI agents? Reputation systems for bots? (Nexus 7)

Let me leave you with the philosophy behind all of this.

"We don't build the cathedral before the congregation arrives. We fund the builders, and from their work we harvest the cornerstones."

This isn't just a clever strategy. It's a fundamental belief about how lasting infrastructure gets created.

Infrastructure that nobody uses isn't infrastructure—it's a monument to hubris.

Infrastructure extracted from real solutions to real problems? That's foundation. That's something you can build a civilization on.

The 7 Nexi won't be theoretical constructs. They'll be battle-tested components, extracted from real ventures, serving real users.

That's The Harvest.

If you've been following this series, you now have the complete picture:

Week 1: The origin—two Renaissance artisans who had what we lost

Week 2: The discovery—why we need seven nexi, not six

Week 3: The thesis—why 2025-2030 is the critical window

Week 4 (Today): The method—how we actually build the infrastructure

Next week: The architecture—what the 7 Nexi actually are, in detail.

But now you understand how they get built. Not in isolation. Not as theoretical constructs. But as harvests from real ventures solving real problems.

If you're a builder who sees a problem that needs sovereign infrastructure to solve...

If you're tired of building on borrowed land, using closed APIs, depending on platforms that can pull the rug...

If you want your work to matter—not just for your company, but for everyone who comes after...

The Genesis Cohort is for you.

Applications open January 15, 2026.

Start preparing now:

• Crystallize your problem

• Design your solution

• Identify the infrastructure components you'll need to build

• Be ready when the gates open

We're not looking for "blockchain enthusiasts."

We're looking for builders who have no choice but to build.

From your solutions, we harvest the future.
