The Autonomous Economy’s Missing Link: Inside Natural’s $30M Quest to Re-Engineer Financial Rails for AI Agents

Executive Overview

When an AI agent identifies the most cost-effective freight carrier, optimizes a delivery route, and drafts the transaction terms, it must ultimately pause and wait for a human supervisor to input a credit card number, click "approve" on a push notification, or authorize an ACH transfer. Modern financial infrastructure—built on legacy systems optimized for human verification, physical signatures, and multi-factor authentication (MFA)—acts as a structural bottleneck for the agentic economy.

Enter Natural, a pioneering financial technology startup designed to dismantle this bottleneck. Founded by a team of veteran fintech founders and engineers, Natural has emerged from stealth to build an "agent orchestration layer" that allows AI agents to hold, move, and settle funds autonomously. To fuel this ambitious undertaking, Natural has secured $30 million in a Series A funding round led by Forerunner Ventures, bringing its total capital raised to $40 million.

Positioning itself in direct competition with established financial giants like Stripe, Natural is not merely adding an API layer to existing banking systems. Instead, it is redesigning payment rails from the ground up to accommodate transactions executed at computer speed rather than human speed.

The Legacy Bottleneck: Why Traditional Financial Rails Fail Autonomous Agents

To understand the necessity of Natural’s mission, one must examine the plumbing of the global financial system. The rails that govern the movement of money today—credit card networks (Visa, Mastercard), automated clearing houses (ACH), wire transfers, and even newer real-time networks like FedNow—were engineered with an implicit assumption: a human is always initiating, verifying, and authorizing the transaction.

Legacy Payment Flow (Human-Centric Friction):
[AI Agent Identifies Task] ──> [Generates Invoice] ──> [MFA / CAPTCHA Prompt] ──> [Human Intervenes] ──> [Manual Approval] ──> [Settlement (Days)]

Agentic Payment Flow (Natural's Architecture):
[AI Agent Identifies Task] ──> [Cryptographic Handshake] ──> [Natural Orchestration Layer] ──> [Autonomous Instant Settlement]

This human-centric architecture relies heavily on friction as a security mechanism. Multi-factor authentication, one-time passwords (OTPs), biometric checks, and CAPTCHAs are specifically designed to block automated scripts. For an AI agent engineered to operate in milliseconds, these security protocols are impassable walls.

Furthermore, traditional business payment terms and dispute resolution mechanisms are built on human timescales. A typical ACH transfer takes one to three business days to settle. Chargeback and dispute processes can drag on for months, requiring manual documentation, human review, and arbitration.

If an AI agent needs to purchase API access, buy cloud computing resources, or settle micro-transactions with thousands of other agents per second, legacy rails fail immediately. The operational overhead of requiring human authorization for micro-payments renders autonomous workflows financially and logistically unviable.

Without a native financial protocol for machines, the vision of a fully autonomous agentic economy remains stalled. Natural’s core thesis is that the future of commerce requires a paradigm shift: moving away from human-centric authorization toward cryptographically secured, programmatic, agent-native payment rails.

The Genesis of Natural: From Post-ZIRP Weariness to a Generational Opportunity

The road to founding Natural was paved with both deep industry expertise and a healthy dose of entrepreneurial skepticism. Co-founder and CEO Kahlil Lalji is no stranger to the complexities of the fintech landscape. He previously co-founded Ivella, a Y Combinator-backed banking and financial product designed for couples.

Ivella navigated the challenging transition of the macroeconomic climate as the Zero Interest Rate Policy (ZIRP) era drew to a close. In 2023, Ivella was acquired by financial platform Earnin, where Lalji spent two years working as an engineer.

└────────────────────────┘      └────────────────────────┘      └────────────────────────┘

Exiting the intense, post-ZIRP fintech environment left Lalji weary of the sector. The regulatory hurdles, capital constraints, and shifting interest rates had burned out many founders in the space. As he prepared to launch his next venture, Lalji’s initial instinct was to avoid the financial sector entirely.

However, as generative AI began to transition from simple text generation to agentic execution, Lalji observed a glaring infrastructure gap. He realized that while the developer stack for AI agents was maturing rapidly—with frameworks for memory, planning, and tool usage expanding by the day—the financial stack was nonexistent.

"I kept on coming back to it," Lalji said in an interview with TechCrunch. "It just feels obvious that agentic payments are going to be structurally the most important problem in the space."

Lalji reunited with his Ivella co-founder, Eric Wang, and partnered with Walt Leung, a former engineering manager at Nextdoor. Together, they founded Natural in 2025. The company was conceived not as a standard software service, but as a fundamental orchestration layer capable of bridging the gap between legacy banking infrastructure and autonomous AI agents.

Under the Hood: The Architecture of Natural’s Agent Orchestration Layer

Natural operates as an agent orchestration and custody layer that enables software agents to autonomously hold, move, and settle funds. Rather than acting as a simple digital wallet, the platform addresses the complex regulatory, security, and operational challenges of machine-to-machine (M2M) and machine-to-human transactions.

Key Architectural Pillars of Natural

1. Autonomous Custody & Wallets:
   Natural provides agents with secure, programmatic wallets. These wallets are governed by smart, user-defined guardrails, allowing developers to set strict parameters around spending limits, approved merchant domains, transaction frequencies, and vendor categories.

2. Cryptographic Identity & Authorization:
   Instead of relying on passwords or MFA, Natural utilizes cryptographic keys to verify agent identity and authorize transactions. This ensures that payments can be signed and settled in milliseconds without human intervention, while maintaining a tamper-proof audit trail.

3. Hybrid Settlement Rails:
   While some Web3-native platforms rely solely on blockchain networks, Natural recognizes that the broader business world still runs on fiat currency. The platform features a dual-rail architecture:

   • Traditional Fiat Integration: Deep hooks into ACH, wire networks, and real-time payment (RTP) systems.
   • Stablecoin Support: Integration of USD-backed stablecoins (like USDC) for near-instantaneous cross-border settlements and micro-transactions.

4. Re-engineered Dispute Resolution:
   In a world where machines transact with other machines, traditional chargeback systems are obsolete. Natural is building automated dispute frameworks that utilize smart contracts and programmatic proof-of-delivery to resolve transaction conflicts autonomously, drastically reducing administrative overhead.

The Competitive Landscape: The High-Stakes Battle Against Stripe

The market for agentic payments is rapidly becoming one of the most fiercely contested battlegrounds in technology. Natural’s ambitious roadmap places it in direct competition with Stripe, the undisputed giant of internet payment processing.

Stripe is not standing still. The company’s leadership has openly acknowledged the shift toward agentic commerce and is actively racing to redesign its own payment rails to accommodate AI agents. Stripe’s massive distribution network, deep engineering talent, and existing integrations with millions of global businesses make it a formidable incumbent.

However, Natural’s leadership believes that legacy tech debt and institutional inertia will slow down giants like Stripe. Building for AI agents requires more than just exposing existing APIs; it requires a ground-up redesign of the core database structures, compliance frameworks, and ledger systems that undergird payment processing.

To level the playing field, Natural has leveraged its clear, agent-first mission to attract world-class engineering talent. The startup has successfully recruited senior staff and principal engineers from fintech heavyweights including Stripe, Ramp, and Square. This influx of veteran talent gives Natural the technical execution speed necessary to outpace larger competitors.

Furthermore, Natural is competing against a wave of specialized, venture-backed startups. For instance, Skyfire Systems, backed by DCVC, is also building a payments backbone for AI agents. However, while Skyfire focuses heavily on stablecoins and decentralized ledger technology, Natural is taking a pragmatic, hybrid approach—building deep support for both Web3 assets and traditional bank-to-bank fiat payments. This hybrid model makes Natural highly attractive to enterprise companies that are eager to deploy AI agents but are legally or operationally unable to hold cryptocurrency on their balance sheets.

Strategic Capital & The Investor’s Thesis

Natural’s $30 million Series A round, which brings its total funding to $40 million, was led by Forerunner Ventures. Founded by Managing Partner Kirsten Green, Forerunner is historically renowned for its early bets on revolutionary consumer experiences and the future of commerce (including investments in Dollar Shave Club, Warby Parker, and Faire).

Natural Funding Trajectory:
┌────────────────────────┐
│  Early Funding         │ ──> $10 Million
└────────────────────────┘
┌────────────────────────┐
│  Series A (Forerunner) │ ──> $30 Million
└────────────────────────┘
┌────────────────────────┐
│  Total Capital Raised  │ ──> $40 Million
└────────────────────────┘

Forerunner’s decision to lead Natural’s round signalizes a broader investment thesis: the future of commerce will not just be defined by where humans shop, but by how autonomous software acts on behalf of humans.

Green was drawn to Natural because of its holistic approach to the problem. Rather than focusing solely on consumer-facing checkout agents, Natural is building the foundational infrastructure that addresses enterprise-grade complexities, including compliance, ledgering, and dispute management.

"The team isn’t just trying to solve a niche checkout problem," an industry analyst noted. "They are building the foundational ledger for the next era of global GDP. If they succeed, they will sit at the center of every machine-to-machine transaction."

The fresh injection of $30 million will be used to accelerate product development, expand the core engineering team, and navigate the complex regulatory and compliance frameworks required to operate a global payments network.

Future Outlook: The Velocity of Money in a Machine-to-Machine Economy

The ultimate promise of Natural extends far beyond improving payment efficiency; it lies in unlocking an entirely new economic paradigm.

When transactions are freed from the constraints of human speed, the velocity of money changes. Today, a business might run payroll once a month, pay vendors net-30, and settle credit card balances once a billing cycle. This delayed settlement structure exists because human administration is expensive and slow.

In an economy run by autonomous agents transacting at "computer speed," these artificial cycles disappear. A company’s AI agent could negotiate, execute, and settle a contract with a vendor’s agent in fifty milliseconds. Micro-payments could flow continuously—fractions of a cent settled per second for real-time API usage, electricity consumption, or data processing.

Lalji believes that the transition to agentic payments will trigger an exponential expansion of the global payments market.

"The number of payments that may occur in the world may be two or three or four orders of magnitude greater than the number of payments that exist today," Lalji stated.

If transactions scale by 100x or 1,000x, the economic throughput of the world will no longer be limited by human working hours. Financial liquidity will become truly continuous, optimizing resource allocation across supply chains, logistics, and digital services in real time.

By building the infrastructure to support this hyper-velocity economy, Natural is positioning itself to be more than just a payment processor. It is striving to become the central nervous system of autonomous commerce—the financial foundation upon which the machine-to-machine economy will be built. As the race between Natural, Stripe, and other emerging fintech pioneers intensifies, the prize is nothing less than the custody and movement of the world’s future digital GDP.
