💬 We are Tandem
On average, two-thirds of users of a B2B SaaS product never become active. In other words, this means that two-thirds of customer acquisition costs, a substantial amount, are never recouped. Current solutions to improve user onboarding are either too expensive (hiring more staff to ensure personalized human support) or ineffective (no product on the market offers a convincing rich and personalized experience).
Tandem's mission is to solve this adoption problem through an AI Copilot directly integrated into SaaS apps. Its goal is to help users achieve their objectives effortlessly.
Tandem:
- welcomes new users (onboarding) with the mission of showing them the product's value as quickly and efficiently as possible
- assists users throughout their lifecycle to help them achieve what they want
Tandem helps users as a human would. It talks to them (by text or voice), shows them (by pointing out on the screen the elements they need to click on), and does actions directly for them.
It is the intelligent assistant of every SaaS app.
Tandem was co-founded by Christophe (CEO) and Manuel (CTO), a team of repeat entrepreneurs with 20+ years combined experience in AI & tech.
🚀 We are backed by Hexa (eFounders)
