How Town ships with speed and confidence with Harmony's AI AppSec agents
Town is an unusually helpful AI assistant that learns how you work, then gets to work. Every user gets their own Townie, a personal assistant with its own name and personality that works across the tools you already use, from email and calendar to Slack and docs. Having raised a $55M Series A led by a16z, Town ships new features nearly daily(!) using agentic development to build the AI assistant that knows their users and how they work.
After the quality and comprehensiveness of their first security review, Town signed up to continuous security testing with Harmony. Their CEO, Jean-Denis Greze, on why: “Super happy with Harmony's pentest. Better, deeper and more thorough than others I've seen.”
Background
Town’s personalised AI assistant works across every tool and surface their users already use, enabling their users to tap into the full potential of AI. Behind the scenes, Town’s engineering team is shipping new features for their customers at lightning speed by leveraging agentic development. Along the way, they deepen their foundation of trust with their users with the help of continuous security testing powered by Harmony’s AI agents and human cyber experts.
The Challenge
Town treats trust and security as core to the product, not as an afterthought. Agentic development at Town is equally about quality as it is about velocity. Traditional cybersecurity scanners and pentests struggle to ensure security given the rapid code velocity of AI-enabled software teams like Town. As Jean-Denis Greze put it: “Harmony operates at a different altitude to other tools. I feel better with Harmony’s depth for sure.”
The Solution
Getting started with Harmony was as easy as granting access to Town’s repository and staging environment. Then, Harmony's AI agents read every line of code, found vulnerabilities, and validated them dynamically against Town’s staging environment. This resulted in findings with clear prioritisation, validated proof-of-concepts, and close remediation support. As Town’s Founding Engineer, George, put it: “Harmony’s findings are very comprehensive and very helpful. I can easily work with an agent to resolve issues by just handing it these results.” Town now leverages Harmony for continuous security reviews, surfacing in-depth findings regularly and automatically without manual lift.
