FinTech · AWS · Cloud-hosted (Bedrock/Vertex/Azure)
Chime runs a proprietary fintech platform on AWS, using S3, Airflow and Spark-based data pipelines that write to Snowflake and then propagate to MySQL and DynamoDB for operational and analytics use.[1][5] AI capabilities, including call summarization, are integrated via Amazon Bedrock into this core architecture rather than being a standalone LLM-native product.[5]
FinTech · AWS · Cloud-hosted (Bedrock/Vertex/Azure)
Cortex investing assistant (Digests) runs on Amazon Nova via Bedrock, chosen for ~80% lower per-token cost; core trading/risk stays in-house ML. Now also exposes agent-trading APIs.
FinTech · On-Prem · Off the LLM map (in-house non-LLM ML)
Unusually for its scale, runs its own data centers (not a hyperscaler) on a single Java platform over PostgreSQL for full control of the payment path. RevenueProtect fraud scoring is in-house ML.
FinTech · AWS · Off the LLM map (in-house non-LLM ML)
BNPL underwriting on large in-house risk ML; off the foundational-LLM map at the core.
FinTech · AWS · Off the LLM map (in-house non-LLM ML)
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.
FinTech · Hybrid · Off the LLM map (in-house non-LLM ML)
Global payments processor on its own infrastructure; large in-house fraud/risk ML; off the foundational-LLM map at the core.
FinTech · AWS · Off the LLM map (in-house non-LLM ML)
