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 electronic trading firms. They noticed the same pattern everywhere: firms would invest millions in execution technology but cobble together notifications and alerting from off-the-shelf tools that were never designed for financial workloads. Missed margin calls, delayed fill notifications, phantom alerts during market stress—these were not edge cases but daily realities.
The founding team set out to build a messaging platform purpose-built for capital markets. The first product was a durable, exactly-once alert delivery system that could route structured messages across email, SMS, Slack, PagerDuty, and proprietary dashboards with cryptographic delivery receipts. Within eighteen months, three tier-one banks were running it in production.
Today ATT employs 75 people across offices in Chicago and London. Our platform handles over 200 million messages 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 trading message is ever lost, delayed, or delivered to the wrong recipient.
Our Values
Reliability
We engineer for five-nines delivery because in trading, 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
A notification is only useful if the recipient understands it instantly. We invest as much effort in message formatting, routing logic, and deduplication as we do in raw throughput, because a well-structured alert at the right time prevents more losses than a dozen dashboards.
Security
Trading alerts carry material non-public information. 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 regulatory retention requirements across jurisdictions.
