The burgeoning field of artificial intelligence is rapidly advancing, with AI agents demonstrating increasing sophistication in executing complex tasks. From identifying suitable vendors for freight delivery and meticulously comparing prices to initiating communications for logistical arrangements, these digital entities are becoming indispensable tools. However, a significant bottleneck persists: the final step of authorizing and executing payments for these transactions still necessitates human intervention. This limitation stems from the fundamental architecture of our current financial systems, designed primarily for human-initiated transactions, not for the seamless, autonomous operations of AI. Addressing this critical gap, a new startup, Natural, has emerged with an ambitious vision to rebuild payment infrastructure from the ground up, aiming to empower AI agents with the ability to conduct financial transactions autonomously. The company has just secured $30 million in Series A funding to fuel this endeavor, positioning it as a formidable contender against established payment processing giants like Stripe.
The AI Payment Conundrum: Bridging the Autonomous Gap
At its core, the modern financial sector relies on what are known as "financial rails"—the intricate network of systems and protocols that facilitate the movement of money and data between financial institutions, businesses, and consumers. These rails, however, were predominantly engineered during an era when financial interactions were exclusively human-driven. Traditional payment methods such as credit cards and the Automated Clearing House (ACH) network inherently require human authorization at various stages. This requirement, while essential for human oversight and security, creates a significant impediment for AI agents designed for high-speed, autonomous operation. An AI agent tasked with procuring services or goods might flawlessly identify a vendor, negotiate terms, and even schedule delivery, only to halt its progress at the point of payment, awaiting a human to approve the transaction. This friction not only slows down operational efficiency but also undermines the very essence of autonomous AI capabilities.
Kahlil Lalji, co-founder and CEO of Natural, recognized this disconnect approximately a year ago. He observed that the pace of AI agent evolution was far outstripping the capabilities of existing financial architecture. "AI agents were evolving faster than existing financial architecture," Lalji stated in a recent interview. He further elaborated that the current systems were ill-equipped to support tasks such as autonomously paying vendors, collecting payments, or engaging in peer-to-peer transactions between AI agents. This realization struck Lalji, who possesses a deep background in banking and finance.
A Founder’s Journey: From Fintech Burnout to AI Payment Innovation
Lalji’s previous entrepreneurial ventures have provided him with invaluable experience in the financial technology space. His last startup, Ivella, a YC-backed banking and financial product tailored for couples, was successfully acquired by Earnin in 2023. Following the acquisition, Lalji spent two years as an engineer at Earnin. However, he admitted to TechCrunch that he had been somewhat disillusioned with the finance sector, particularly after the end of the Zero Interest Rate Policy (ZIRP) era, which had significantly altered the investment landscape and the dynamics of fintech startups. This experience left him with a desire to pivot away from finance in his next venture.
Despite his reservations, the sheer magnitude of the opportunity presented by the AI payment challenge proved too compelling to ignore. "I kept on coming back to it," Lalji confessed. "It just feels obvious that agentic payments are going to be structurally the most important problem [in the] space." This persistent conviction led him to re-engage with the financial sector, this time with a focus on a problem that directly impacts the future of AI.
Natural’s Vision: Rebuilding the Financial Backbone for AI
Driven by this insight, Lalji reunited with his former co-founder at Ivella, Eric Wang, and Walt Leung, a former engineering manager at Nextdoor. Together, they founded Natural in 2025. The startup’s core mission is to establish itself as an "agent orchestration layer," a fundamental infrastructure that empowers AI agents to manage and execute financial transactions seamlessly. By integrating Natural’s platform, companies can enable their AI agents to autonomously handle payments, collect funds, and transact with both human users and other AI entities.
Natural’s innovative approach has garnered significant attention from the venture capital community. Kirsten Green, founder and managing partner at Forerunner, a firm known for its focus on consumer experiences and the future of commerce, led Natural’s $30 million Series A funding round. This investment brings the company’s total funding to $40 million, underscoring the strong market confidence in Natural’s disruptive potential.
Green was particularly drawn to Natural’s expansive vision. The startup’s ambitions extend beyond merely facilitating AI agents to purchase goods and services on behalf of consumers. Natural aims to fundamentally reinvent payment infrastructure, addressing not only the execution of transactions but also crucial aspects like dispute resolution mechanisms, which are inherently complex in an autonomous environment.
Competing with the Titans: A Race to Redefine Payments
While Natural has been operating in a closed beta trial, Lalji expressed confidence in the company’s strategic architectural decisions. He believes these decisions provide Natural with a "good shot" at competing directly with established industry leaders such as Stripe. Stripe, itself a dominant force in payment processing, is also reportedly investing heavily in developing payment rails optimized for AI agents.
Lalji is betting on Natural’s agility and rapid development cycle to outmaneuver larger, more established players. The company’s objective is to build the foundational payment infrastructure that will serve as the financial nervous system for the next generation of AI agents. This ambitious undertaking has already attracted seasoned talent from leading fintech companies, including former employees from Stripe, Ramp, and Square, a testament to the compelling nature of Natural’s mission.
While Natural identifies Stripe as its primary competitor, it operates in a burgeoning ecosystem with other startups also vying to redefine the AI payment landscape. For instance, DCVC-backed Skyfire Systems is exploring the use of USD-backed stablecoins to create a payment backbone for AI agents. Natural, while also planning to incorporate stablecoin support into its architecture, is simultaneously developing robust support for traditional bank payments, aiming for a comprehensive and flexible solution.
The competitive landscape for AI payment infrastructure is intensifying, but Lalji remains optimistic about the market’s potential for exponential growth. He envisions a future where transactions occur at "computer speed rather than human speed." This paradigm shift, he predicts, could lead to a monumental increase in the volume of financial transactions globally. "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, highlighting the transformative impact of enabling autonomous, high-frequency financial operations for AI.
The Broader Implications: A New Era of Autonomous Commerce
The implications of Natural’s work extend far beyond simply enabling AI agents to make purchases. The development of autonomous payment systems has the potential to revolutionize various industries, from supply chain management and e-commerce to decentralized finance and automated marketplaces. Imagine a future where supply chain AI agents can autonomously reorder raw materials when inventory levels dip below a certain threshold, negotiating prices and executing payments in real-time without human oversight. Or consider e-commerce platforms where AI assistants can manage customer returns and process refunds instantly, significantly enhancing customer satisfaction.
The ability for AI agents to transact autonomously also paves the way for more sophisticated forms of decentralized autonomous organizations (DAOs) and automated market makers, where smart contracts and AI agents can interact and exchange value with unprecedented speed and efficiency. This could unlock new economic models and accelerate innovation across the digital economy.
However, this rapid advancement also brings forth critical considerations regarding security, regulation, and ethical oversight. As AI agents gain the ability to move and store funds autonomously, robust security protocols will be paramount to prevent fraud and unauthorized access. Furthermore, regulatory frameworks will need to adapt to accommodate these new forms of financial activity, ensuring consumer protection and market stability. The question of liability in case of errors or malicious actions by AI agents will also require careful consideration and clear guidelines.
Natural’s approach of building a comprehensive agent orchestration layer, which includes support for both traditional and emerging payment methods like stablecoins, suggests a strategy to bridge the existing financial infrastructure with the future needs of AI. By addressing the foundational problem of autonomous payments, Natural is not just building a product; it is laying the groundwork for a fundamentally new era of commerce and economic interaction, driven by intelligent agents operating at machine speed. The successful execution of this ambitious vision could indeed reshape the global financial landscape and unlock unprecedented levels of efficiency and innovation.
