market profile

• text: AI applications need durable, real-time token streams, agent communication and observability.
• text: Streaming buyers evaluate managed Kafka and other durable logs against the operational burden of running clusters.
• text: S2 became generally available in 2026 and reported customers creating millions of streams weekly.

personas

• title: Platform or infrastructure engineer
  pains:

  • Maintaining streaming clusters takes time away from application development.
  • Provisioning and securing many individual streams adds operational work.
• title: AI application engineer
  pains:

  • Long-running sessions must survive disconnected clients and workers.
  • Agent state needs a durable history for recovery and debugging.
• title: Product engineer building real-time applications
  pains:

  • Users need both live telemetry and historical replay.
  • Clients and services need a consistent sequence of changes.

icp

• text: Software companies shipping agent sessions, live observability, application sync or real-time feeds.
• text: Engineering teams of varying sizes that prefer metered infrastructure to managing Kafka clusters; firm size is not specified.
• text: Teams with a large number of granular streams and a need to retain and replay events.

message pillars

• text: Use familiar HTTP operations instead of operating streaming clusters.
• text: Retain a durable event history and replay it when needed.
• text: Support agent communication through dropped connections.

objections

• objection: Can the service meet our latency and throughput targets?
  response: Benchmark the actual workload and region using the published benchmark tool before adopting it.
• objection: Will usage costs be predictable?
  response: Estimate retained data, reads, writes and operations against the published metered rates.
• objection: Can we use it with regulated data?
  response: Request and review the SOC 2 report and HIPAA BAA with the security team.

competitors

• name: Confluent
  why: Managed Kafka and event-streaming infrastructure compete for durable streaming workloads.
• name: Redpanda
  why: Kafka-compatible streaming platform offers another route to managed event infrastructure.
• name: Ursula
  website: https://ursula.tonbo.io/docs/competitive-comparison/
  why: Its own comparison describes S2 as a close alternative for many small durable streams.

influencers

• name: Shikhar Bhushan
