Philippe-Antoine Lehoux

Philippe-Antoine Lehoux, known as Phil, is co-founder and chief executive of Missive, a team inbox that combines shared email, live chat, tasks, and rules-based automation. He is based in Quebec City, Canada, and has grown Missive on its own revenue since it started.

A teenage game portal

As a teenager he created a French-language game portal, and its income later helped carry him while he ran a coworking space he opened in 2012, he told Nathan Latka. At that space he met the developer and designer who became his co-founders.

Their first business was Conference Badge, a spreadsheet-driven tool for printing event name badges. Missive began as the inbox they built to handle Conference Badge’s customer support. It launched as a paid product in 2016 and earned about $3,000 that year.

Four people and a million dollars

By early 2021 Missive had passed $1 million in annual recurring revenue with three co-founders and one employee. “It’s all about being small, it’s about being more agile to me. We really don’t lose time,” he said. Growth came mostly from search and word of mouth. “We never really invest our time in marketing.”

He turned down an acquisition offer worth $30 million in equity that would have required him to move to San Francisco. Asked what he wished he had known at 20, he answered: “Take my time.” He is married with four children, and he follows hockey and rugby and goes bikepacking.

AI that stays in the background

By mid-2025 Missive had passed $8 million in annual recurring revenue, still without outside money, he told ValiantCEO. He is wary of software that promises to do everything with AI. “The best use cases are where AI works quietly in the background, enhancing your workflow without demanding your trust blindly,” he said. Missive’s AI Rules feature lets a team write a plain-English test, such as whether an email is urgent, and route or flag messages that match.

Missive’s about page now lists more than 6,500 customer companies and 17 employees.
