No shared foundational model — different bets.

Architecture

Carta operates a proprietary, cloud-based equity and private capital management platform, most likely hosted on AWS using a relational database such as PostgreSQL. Public information focuses on product capabilities rather than disclosing detailed production architecture, so deeper specifics cannot be reliably verified.

Architecture

Stripe’s publicly documented infrastructure shows heavy AWS usage for observability and operations, plus a sharded/tiered storage design that Stripe built to scale data access and migrations. Public sources do not confirm a core production reliance on a foundational LLM; the available evidence points to a proprietary payments platform rather than an open model stack.
