Proaction builds software for businesses that manage fleets of vehicles. Personalized demos required engineering time the team couldn’t spare. Codex flipped the script. “As a non-technical person, I used to have to loop engineers in if I wanted a demo,” says Colin Knudsen, co-founder and COO of Proaction. “Now I do it myself in Codex.” Colin creates four to six customized, interactive demos a month, with each taking 30 to 45 minutes to build. He estimates that this avoids 40 to 60 hours of engineering work.

After a sales call, Colin directs Codex to the Granola recording, prospect email threads, and any spreadsheets the prospect has shared. Codex uses that context to customize an HTML demo environment that mirrors Proaction’s product and the customer’s own fleet. Colin estimates that the percentage of deals moving from initial contact into solution development has increased by 50% to 60% with the custom demos.

Saving engineering hours all the way to production. When a prospect becomes a customer, Colin gives engineers the customized demo as a visual reference. That reduces questions and back-and-forth about what to build. Colin’s daily work spans sales, customer support, and product management. Through Codex plugins for tools including Granola, Gmail, Slack, Linear, Git Hub, and Hub Spot, Colin brings together customer context and acts on it within Codex. Estimating he has 15 to 20 distinct tasks a day, Colin believes Codex saves him 25–33 hours a month.
