What Momento does

Momento is a Seattle-headquartered, venture-backed data infrastructure company founded in 2021 by the team behind Amazon DynamoDB. It operates a fully managed, serverless real-time data platform whose foundation is Momento Cache — a sub-millisecond, in-memory cache built on a tuned and hardened Valkey (Redis-compatible) engine, paired with an intelligent control plane that handles sharding, scaling, hot-key isolation, automated failover, and zero-downtime upgrades. Layered on the same data plane are three additional modules: Momento Topics (serverless pub/sub event bus), Momento Leaderboards (serverless ranking service), and Momento Media Storage (a RAM-cache-based live streaming origin positioned as a drop-in replacement for the deprecated AWS Elemental MediaStore).

The platform is sold to enterprises operating latency- and scale-sensitive workloads, with named customers spanning media and entertainment (CBS, Fox, Warner Bros. Discovery, Paramount, DirecTV), gaming (Capcom, ZigZaGame), fintech and social (Coinbase, Snap), QSR (Taco Bell), consumer IoT (Wyze), telecom (NTT DOCOMO), and professional sports (four MLS clubs via Sports Illustrated Tickets). Customer-reported outcomes include CBS Interactive's 15% performance improvement at half the price of Amazon ElastiCache and ZigZaGame's 30% TCO reduction after migrating to a fully serverless architecture in three weeks.

Momento generates revenue through a multi-tier enterprise pricing model — Flex (pay-as-you-go from $5,000/month for 20 billion operations), Provisioned (reserved capacity at $10,000/month for 250,000 ops/sec), Business Critical (custom-priced single-tenant, BYO-cloud, or self-managed deployments), and a legacy on-demand plan at $1 per million operations — with go-to-market executed through a combination of enterprise direct sales, a public self-serve pricing surface, partner-delivered deployments (Sports Illustrated Tickets), and a heavy event- and community-led motion (Infer Summit, AWS re:Invent, IBC, NAB, QCon, Valkey meetups). The company has raised $30M across a 2022 seed and 2024 Series A, both led by Bain Capital Ventures, and has opened a Tokyo office to support APAC expansion; its Series A is explicitly tied to growing its AI inference infrastructure footprint.

Core offering

Momento provides a fully-managed, serverless data platform built on a tuned and hardened Valkey (Redis-compatible) engine. The core product, Momento Cache, delivers sub-millisecond in-memory caching with multi-AZ reliability, hot-key shielding, automated failover, and adaptive auto-sharding. Layered on top are Momento Topics (serverless pub/sub), Momento Leaderboards (serverless ranking), and Momento Media Storage (RAM-cache live streaming origin) for game, AI, fintech, and media workloads.

Product overview

Momento offers a platform-plus-modules architecture built around a single unified core: Momento Cache, a serverless Valkey-based cache that is the foundation of the product line. Layered on top of Cache are serverless add-on modules — Momento Topics (pub/sub messaging), Momento Leaderboards (serverless ranking), and Momento Media Storage (live video origin). Together, the Cache core and the Topics/Leaderboards/Media Storage modules give developers a fully serverless data plane for games, AI, and media workloads, with native SDKs for Unity, Unreal, Swift, Kotlin, and Web. The valkey-lab open-source benchmarking tool is an adjacent offering for the Valkey ecosystem.

Direct peers

• Redis: The original managed Redis/Valkey provider and the incumbent Momento directly competes with on protocol-compatible in-memory caching. Both target enterprise caching, real-time leaderboards, and pub/sub workloads on a Redis-compatible API, making Redis the closest direct comparison.
• Upstash: Serverless managed Redis-compatible platform with usage-based pricing and a similar developer-first go-to-market. Upstash directly competes with Momento Cache on the same developer persona, Redis-compatible API, and serverless delivery model.
• Aerospike: Real-time NoSQL data platform offering low-latency in-memory storage used for caching, session, and profile workloads at scale. Aerospike is a direct peer in the high-performance real-time data plane category where Momento competes for gaming, fintech, and ad-tech use cases.

Broad incumbents

• AWS ElastiCache: Hyperscaler-managed Redis/Memcached service that Momento explicitly benchmarks against (CBS Interactive's 15%-better-at-half-the-price claim). ElastiCache is the broad incumbent bundled into AWS accounts that Momento displaces in enterprise caching deals.
• AWS MemoryDB: AWS-managed Redis-compatible durable in-memory database. As a broad incumbent within the AWS ecosystem, MemoryDB is a substitute target for Momento's Cache, especially for customers preferring single-vendor AWS commitments.
• ScyllaDB: Low-latency NoSQL database used for high-throughput caching and real-time workloads in gaming, ad-tech, and IoT. ScyllaDB overlaps with Momento on latency-sensitive enterprise use cases even though it is not Redis-protocol-compatible.
• Hazelcast: Distributed in-memory data grid used for caching, stream processing, and low-latency enterprise workloads. Hazelcast is a broad incumbent in the same real-time data platform category that competes for enterprise caching RFPs.
• Confluent (Kafka): Leader in real-time streaming infrastructure with managed Kafka. Confluent competes with Momento Topics (pub/sub) at the messaging/event layer and represents a broad incumbent alternative for real-time event distribution.

Emerging players

• Dragonfly (DragonflyDB): High-performance Redis-compatible in-memory data store with a modern multi-threaded architecture targeting similar sub-millisecond, high-RPS workloads. Dragonfly is an emerging direct competitor in the same cache-plus-data-structure category.
• Ably: Managed real-time messaging and pub/sub platform targeting the same developer persona as Momento Topics. Ably is an emerging peer in the serverless real-time messaging category where Momento is expanding beyond cache.
