About this role
About Kantiv
Kantiv, formerly Joist AI, is the pursuit intelligence platform built for Architecture, Engineering, and Construction firms. AEC firms run on proposals: every year, marketing teams spend thousands of hours hunting for content, pulling technical input out of busy engineers, and rebuilding institutional knowledge from scratch on every pursuit. Kantiv changes that. We connect a firm's expertise, project history, and client data into an intelligent system that gets smarter with every proposal the team runs. The result is a marketing team that stops scrambling and starts winning.
We were founded by people who came up through AEC marketing and know firsthand what it costs when talented teams spend their best hours on the grind instead of the strategy. That insider knowledge shapes everything we build and everything we take to market.
