Natural builds payment infrastructure that lets autonomous AI agents execute financial actions such as paying vendors, collecting payments, and transacting with other agents or humans. The startup redesigns financial rails to support agent-initiated transactions that traditional systems (credit cards, ACH) were not built for. Founded in 2025 by Kahlil Lalji with co-founders including Eric Wang and Walt Leung, Natural has operated in beta while making core architectural decisions. The company plans to support both traditional bank payments and USD-backed stablecoins as part of its architecture. Natural has attracted senior talent from fintech firms like Stripe, Ramp, and Square to accelerate product development. With $40 million in total funding after the Series A, the company is positioning itself to compete with incumbents such as Stripe and emerging rivals in the agentic payments space.

Neuralink develops implantable brain-computer interface devices that decode neural signals to enable control of phones, computers and other systems. The company is conducting first human trials across three countries and reports that five patients with severe paralysis are using its device to control digital and physical systems by thought alone. Regulators have granted its speech restoration system a Breakthrough Device designation from the FDA, and the company previously received a similar designation for a vision-restoring implant. Financially, Neuralink announced a $650 million capital raise with participation from multiple top-tier investors, and reports earlier financing of $600 million at a reported $9 billion valuation. The company says the funds will be used to expand clinical testing and bring its technology to more people with unmet medical needs.

Monaco has built a sales technology suite that integrates an AI-native customer relationship management system with a proprietary ZoomInfo-style prospect database. Its AI agents generate target lists, orchestrate multi-step email sequences, draft follow-ups, capture meeting notes, and schedule calls, while experienced human salespeople remain in the loop to verify outputs and run customer meetings. By pairing software with a managed service layer, Monaco aims to give seed and Series A startups access to enterprise-grade sales talent without having to hire full teams. The company opened its product to a public beta after a period of private testing and currently charges a flat, discounted fee during this phase. Although the market is crowded with incumbents like Salesforce and HubSpot and dozens of newer AI SDR tools, Monaco believes a platform shift will create room for a new category leader. The 40-person company is led by co-founders Sam and Brian Blond, along with former executives from Apollo, Qualtrics, and Clari. To date, Monaco has raised $35 million across seed and Series A financings led by Founders Fund, giving it ample capital to refine its product and scale go-to-market efforts.
