Culture Amp measures how work feels. Ren helps with the conversations that shape it.
Culture Amp
Culture Amp is an employee experience platform: engagement surveys, people analytics and benchmarks, performance reviews and goals, and manager development tools. It helps HR and leaders understand what is happening across the company and where to focus.
Ren
Ren is an AI app in Slack and Microsoft Teams for the conversations between people at work. It notices the conversations that aren't happening, helps you tell how serious a situation is on the Accountability Dial™, and helps you find the first sentence. For every seat, not only managers.
Short answer: Culture Amp and Ren work on different ends of the same problem. Culture Amp is an employee experience platform: engagement surveys, people analytics, performance reviews and manager development tools. Ren is an AI app in Slack and Microsoft Teams that helps people have the everyday conversations those surveys end up measuring: early, in their own words, before a small pattern turns into a low score. If you need to measure and benchmark across the company, that's Culture Amp. If people keep putting off the conversations, that's Ren. Plenty of teams use both.

The gap between the survey and the conversation
Culture Amp is good at listening across a whole company: careful survey design, benchmarks, and a clear view of which teams are struggling. The report is usually right. Here is what tends to happen next:
- The survey shows a manager's team scores low on clarity.
- The people team shares the report. The manager reads it and agrees it's fair.
- Monday, a deliverable slips. The manager isn't sure if it's worth raising, so it waits.
- Thursday's 1:1 runs the way 1:1s always run.
- Next cycle, the same score.
The manager wasn't unwilling. They just didn't know what to do differently in the actual moment: the slipped deadline, the meeting that went sideways, the teammate who went quiet in sprint review. The survey captured the missing conversations. It couldn't have them. That's the part Ren works on.
What Ren adds
- It notices. In the Slack and Teams channels you add it to, Ren picks up the patterns: repeated slips, unanswered asks, work that deserved credit.
- It calibrates. Ren uses the Accountability Dial™ to suggest how direct to be. A first slip is a Mention, not a sit-down about the survey.
- It finds the words. Ren drafts the first sentence in your voice, and asks why this one is hard for you.
- It works in every direction. Peers, someone raising a concern with their manager, and praise, not just top-down feedback.
When to choose which
- Choose Culture Amp if you need engagement surveys, benchmarks, people analytics or review cycles across the company.
- Choose Ren if the hard conversations aren't happening, or happen too late, or if you're a smaller team that doesn't need a survey platform.
- Use both if you want the company-wide picture and the day-to-day conversations that change what it shows.

The questions buyers actually ask.
What is the difference between Ren and Culture Amp?
Culture Amp is an employee experience platform: engagement surveys, people analytics, performance reviews and manager development tools. Ren is an AI app in Slack and Microsoft Teams for the conversations between people: it notices when one isn't happening, helps you judge how serious it is, and helps you open it. Culture Amp shows you what people think, a quarter at a time. Ren works on this week's conversation. Many teams use both.
Is Ren a Culture Amp alternative?
Only if what you are missing is the conversations, not the measurement. If you need engagement surveys, benchmarks, people analytics or review cycles, Culture Amp does that and Ren does not. If you already have the survey results and the same issues keep coming back, or you are a smaller team that doesn't need a survey platform, Ren covers the part Culture Amp doesn't.
Can you use Ren and Culture Amp together?
Yes. They work at different points in time. Culture Amp shows HR and leaders where things stand across the company and where to focus. Ren works in Slack and Teams day to day, so the slipped deadline or the work that deserved credit gets a light, early Mention instead of turning up months later as a low score in a report.
Why do the same issues keep showing up in survey results?
A survey measures how the last few months felt. It can tell a manager that clarity is low or feedback is rare, but it can't tell them what to say on Monday when a deliverable slips. So the report gets read, everyone nods, and the next cycle shows the same thing. The missing piece is the everyday conversation, which is where Ren works.
Can you use Ren without Culture Amp?
Yes. Many teams using Ren run no survey platform at all. Ren doesn't depend on any other tool. It works from the Slack and Teams channels you add it to, and from a web app, and it is useful from the first week rather than after a survey cycle.
How does privacy compare?
Culture Amp collects survey responses and reports them to HR and leaders, and holds performance records managers read. Ren is private by design: it cannot read direct messages between people, your conversations with Ren are never shared with your manager or HR, and the team-wide view is aggregate and never traceable to a person. Ren is SOC 2 Type II.
