Deep Tide Guide: a16z Crypto operating partner Jason Rosenthal outlines three current paths for crypto projects to find Product-Market Fit: collaborating with top-tier clients to build, positioning on the exponential growth curve of AI Agents, and becoming your own first user. The article uses case studies from LayerZero, AgentCash, ZKsync, etc., offering direct reference value for teams pivoting or still searching for PMF.
Product-Market Fit (PMF) is the most critical variable determining a company's survival. Find it, and you have a chance. Fail to find it, and nothing else can save you.

Finding and achieving Product-Market Fit is the most powerful and important thing for any early-stage startup. I've spent a significant part of my career on this, across multiple companies. Here are 5 strategies for finding PMF in Web3.
Throwing more money at the problem just extends the runway to a bad ending. Growth hacking and continuous airdrops disconnected from a real strategy are less a path to PMF and more a way to mask the fact that you haven't found it yet. Some of crypto's most powerful weapons (tokens and network effects) can even mislead projects about their PMF.
The good news is that top teams are now finding PMF faster. Killer applications like stablecoins have been proven, and traditional finance and broader consumer groups are accelerating their entry.
Here are three models that are working. If your project is pre-PMF or pivoting, pay close attention.
1. Partner with Top Clients, Build to Their Specifications
Identify the most sophisticated potential clients in your field and build the product together with them. Their needs are your product spec sheet.
This is slower than building a generic product and iterating publicly. But if your first client handles trillions in daily transaction volume, their adoption is more valuable than any press coverage, TVL numbers, or retail attention. The essential definition of PMF is your product resonating broadly with customers, and these flagship clients are the best indicator.
Judging by the high-profile partnership announcements and product launches between crypto startups and traditional finance firms, product roadmaps are now being written by institutional clients. Blockchains are beginning to host global financial infrastructure.
2. Identify an Exponential Growth Curve and Position Ahead of It
PMF sometimes comes from serving an existing market better. Other times it comes from seeing where a market is going before it fully realizes it itself, and positioning early enough.
The most obvious current curve: AI Agents are becoming economic actors. They autonomously call APIs, deploy capital, and execute transactions at machine speed. The assumption of "human-in-the-loop" is collapsing faster than most expected.
Take Agent commercialization. Samuel Ragsdale and Ryan Sproule at Merit Systems saw this early and are building AgentCash on the x402 protocol. AgentCash enables AI Agents to pay for API access using cryptocurrency, an infrastructure that allows Agents to conduct programmatic transactions without human-managed billing.
Payment is the key link that turns Agents from "assistants" into "participants." Whoever builds these payment rails now will own a foundational layer when the Agent economy arrives.
3. Be Your Own First (and Best) Customer
The most enduring infrastructure companies don't wait for external developers to validate their technology. They build applications on their own rails first, proving capability through live operation, and then invite others to use it.
Amazon executed this playbook masterfully. AWS wasn't sold to startups from day one. Amazon first built the infrastructure needed for its own e-commerce business, proving it at massive scale, before gradually opening it to others.
Matter Labs' Alex Gluchowski is running the same playbook.
Instead of pitching Prividium as an abstract enterprise product, he anchored it to a specific application: tokenized deposits. The result is Cari Network. U.S. regional banks like Huntington Bancshares, First Horizon, M&T Bank, KeyCorp, Old National Bancorp can now transfer customer deposits across banks in real-time on a blockchain rail, while the funds never leave the regulated banking system. ZKsync didn't just build the rail; it found the killer application on it.
Three models, one underlying logic: The fastest path to PMF isn't fumbling in the dark, but choosing the right battlefield and fighting with conviction before everyone else jumps in.
Co-build with the client whose validation compounds. Position ahead of the curve before consensus forms. Be your own first and best customer.
Pick the model that fits your product, and execute.
