AI assistants are evolving beyond information and recommendations. As they begin to facilitate transactions, regulated industries such as insurance will need infrastructure that enables these interactions to happen safely, compliantly and at scale.
Marrow is building that infrastructure.
We invested in Marrow because we believe AI will become a meaningful distribution channel for insurance - and insurers need a way to participate without giving up control of underwriting, compliance or the customer relationship.
Marrow provides that missing layer: one connection for insurers, one protocol for AI channels, and the governance required to transact safely between them.
Importantly, this is already moving beyond thesis. Marrow has been live in production with Aviva since March 2026, having cleared procurement, information security, legal and data protection reviews. It is now expanding its work across a growing network of carriers, brokers and MGAs.
What Makes Marrow Different
Marrow is not another insurer chatbot or point integration. Insurers connect their existing systems once, while multiple AI channels can access their products through a common protocol. Marrow sits in the middle, enforcing underwriting rules, disclosures, data controls and auditability across every interaction.
That creates the potential for Marrow to become shared infrastructure for AI-native insurance distribution, rather than another piece of insurance software.
Executing this requires a rare blend of insurance domain depth and technical capability:
• Tim Graham (Founder & CEO): Combines hands-on insurance distribution experience with AI product development expertise.
• Adam Mesout (Co-Founder & CTO): Brings actuarial science mastery and deep engineering experience directly from the insurance sector.
Together, Tim and Adam bring the exact actuarial grounding and AI-native engineering required to navigate complex workflows and build the standard transaction layer for the future of insurance.
Strategic Fit with Leo Capital
Marrow fits our thesis by delivering purpose-built infrastructure for AI-mediated insurance distribution, positioning itself as a neutral, shared transaction layer between carriers and emerging AI channels. Operating in this space requires deep domain expertise far beyond wrapping an LLM, it demands native integration with complex actuarial, underwriting, and compliance workflows. Co-founders Tim Graham and Adam Mesout bring the exact combination of insurance distribution, actuarial science, and AI product experience needed to execute. Supported by strong early production traction, Marrow is uniquely positioned to define the infrastructure standard for AI-driven financial services.
Marrow fits squarely within our thesis of backing domain-native teams building the infrastructure layer for AI adoption. We are particularly drawn to markets where AI creates not just a better application, but the need for an entirely new layer of infrastructure and we believe insurance distribution is one of them.
