ATT

About ATT

ATT was founded in 2020 by a group of infrastructure engineers who had spent years building internal messaging systems at two of the world's largest cloud-native technology companies. They noticed the same pattern everywhere: organizations would invest millions in microservices architecture but cobble together event delivery from off-the-shelf message brokers that were never designed for mission-critical workloads. Lost webhooks, duplicate events during failover, phantom alerts during traffic spikes — these were not edge cases but daily realities.

The founding team set out to build a messaging platform purpose-built for event-driven architectures. The first product was a durable, exactly-once event delivery system that could route structured messages across webhooks, Kafka topics, SQS queues, Slack, PagerDuty, and proprietary endpoints with cryptographic delivery receipts. Within eighteen months, three major SaaS platforms were running it in production.

Today ATT employs 75 people across offices in Chicago and London. Our platform handles over 200 million events per day across 40 client installations, and we maintain a 99.999% delivery success rate measured over the trailing twelve months. We remain privately held and reinvest the majority of revenue into platform reliability and security.

Our Mission

To ensure that no critical event is ever lost, delayed, or delivered to the wrong consumer in a distributed system.

Our Values

Reliability

We engineer for five-nines delivery because in event-driven systems, the message you miss is the one that matters most. Every component is designed with redundancy, automatic failover, and persistent delivery guarantees that survive node failures, network partitions, and datacenter outages.

Clarity

An event is only useful if the consumer understands it instantly. We invest as much effort in schema validation, routing logic, and deduplication as we do in raw throughput, because a well-structured event at the right time prevents more incidents than a dozen monitoring dashboards.

Security

Events carry sensitive business data — payment confirmations, user actions, system state changes. We encrypt every message at rest and in transit, enforce role-based access controls at the topic level, and maintain a tamper-evident audit log that satisfies SOC 2 and GDPR requirements.
