Choosing a performance management platform is one of the most important decisions an HR leader makes. The platform you pick shapes how managers develop, how performance data gets used, how employees experience feedback, and ultimately, whether HR is positioned as a strategic function or an administrative one.
Culture Amp and 15Five are two of the most recognized platforms in this space, and they're frequently evaluated side by side. Both are well-built. Both have invested meaningfully in their products. Culture Amp built a strength around engagement surveys through its question library, benchmarks, and survey tooling. It's also a solid choice if you're an HR team that's primarily focused on listening to employees and reporting on sentiment to leadership.
15Five is the stronger fit if you need engagement to connect to everything else. If your HR team is being asked to play a more strategic role by linking people data to business outcomes, enabling managers to lead better, and making compensation and talent decisions grounded in real performance data, 15Five was built for that work.
Here's a look at situations when 15Five is the better fit and why.
When you need engagement, performance, and retention data to work together
Culture Amp's analytics are centered on engagement. That's useful, but often HR leaders need a more complete picture.
When engagement scores dip in a particular team, the natural next questions are:
- How is that team performing?
- Are people at risk of leaving?
- What's the manager doing, or not doing, that might explain both?
15Five's Amaya, Insights Dashboard, and HR Insights Dashboard are built to answer those questions in one place. It connects engagement, performance, and retention data so HR leaders can see the full picture and act on it, rather than pulling from separate reports and trying to stitch the story together themselves.
15Five is the only platform that connects all three data types to personalized action plans so the insight doesn't stop at the dashboard. It leads somewhere.
When manager development is a strategic priority
According to 15Five's Manager Effectiveness Report, 52% of employees have left a company because of unsupportive management, and 56% say having a good manager is one of the most critical factors in staying. Managers are the single biggest lever HR has, and that means giving them more than survey data to work with.
15Five's Manager Effectiveness and Behavior Dashboards are unique in the market. They go beyond what an engagement platform can show you by tracking the specific behaviors that drive team outcomes, like how often managers are holding 1:1s, how they're giving feedback, and how their teams are performing relative to engagement scores. HR leaders can see which managers need support and where, and act before problems compound.
From there, 15Five pairs those insights with Kona by 15Five, its AI-powered manager effectiveness coach. Kona joins scheduled 1:1s in Zoom, Google Meet, or Microsoft Teams, connecting to Google or Outlook calendars automatically. During those meetings, it captures key moments like progress updates, wins, blockers, and action items, so managers can stay fully present in the conversation rather than splitting their attention between the person and their notes.
Over time, those summaries build a continuous record of each employee's contributions throughout the review period. When review season arrives, Kona compiles those summaries into a fair, balanced, ready-to-edit performance snapshot, saving managers hours of writing and eliminating the recency bias that distorts so many reviews.
What sets Kona by 15Five apart from generic AI notetakers is that it was designed specifically for performance management. It knows which insights matter for reviews like feedback, progress, development, and filters out personal conversations that aren't relevant. It's fully integrated into 15Five, so managers move directly from conversation to performance cycle without copying notes across tools.
Kona also uses data from performance reviews and engagement surveys to help managers continuously improve across leadership skills, like running more effective meetings and navigating difficult performance conversations. And it automatically tracks changes in manager behavior over time, giving HR leaders an ongoing view of what's working and where managers need more support.
Privacy was built into Kona by 15Five from the start. All personally identifiable information is removed before any data is processed. The de-identified data is never retained or used for model training. Notes and summaries from 1:1s are private to the manager and their direct report. HR administrators cannot see them without the manager's explicit consent. Companies also have full control to enable, restrict, or disable AI features as they see fit.
Culture Amp has AI-assisted coaching as well, but it operates separately from a connected performance and behavior data set, which limits how targeted and actionable the guidance can be.
When performance reviews need to go deeper
15Five offers a research-based, fully customizable, and flexible review system that includes self-reviews, manager reviews, upward reviews, competency reviews, objective reviews, and peer reviews. HR leaders can draw from a built-in, evidence-based question bank to reduce the manual work of building review cycles from scratch. 15Five offers over 25 integrations, giving HR teams flexibility in how they build their tech stack.
Culture Amp offers customizable performance reviews, but 15Five's review system is designed to feed directly into calibration, talent decisions, and compensation, keeping everything connected.
That connection matters especially when it comes to calibration. 15Five has delightfully designed full calibration and talent review workflows built into the platform. Culture Amp does not offer calibration. For HR leaders running structured calibration sessions where managers compare ratings, surface potential high performers, and align on talent decisions together, which is a real gap in what Culture Amp can support.
When you need goals to connect to performance
15Five's OKR system uses weighted objectives, meaning teams can prioritize what matters most within a set of goals rather than treating every objective equally. That nuance reflects how real goal-setting works, where not all priorities carry the same weight at a given time.
Beyond that, 15Five is built so that OKRs, 1:1s, check-ins, and feedback all live inside the same system and reinforce each other. When a manager sits down for a 1:1, they can see goal progress, recent feedback, and pulse data in the same place. That continuity keeps performance as an ongoing conversation rather than a twice-a-year event.
Culture Amp's coverage of 1:1s, check-ins, and continuous feedback features exists, but aren't as developed or as central to how the platform is designed to be used.
When compensation decisions need to connect to people data
Many HR teams still manage compensation cycles in spreadsheets that have no connection to their performance data. That creates risk both in terms of accuracy and fairness. 15Five Compensation addresses this directly. It gives HR leaders a way to make performance-based pay decisions through one-click integrations with established compensation platforms, without manual data exports or reconciliation work.
15Five uses performance and engagement data, as well as compensation management and internal and external benchmarking tools, to help you get a full picture of how competitive your compensation strategy is.
In 15Five, compensation is embedded as part of a unified system, directly connected to performance reviews, engagement insights, calibration workflows, and HR outcomes dashboards. It becomes part of the same strategic data model that powers performance and retention decisions.
In Culture Amp, performance data syncs to a third party through an integration, and compensation reviews are run within the third-party platform. Performance informs compensation, but the workflow lives across different systems. Instead of being an embedded part of your performance strategy, it’s an integrated add-on connected through data sync.
When AI needs to do more than surface insights
Both platforms have invested in AI, but apply it in different ways. Culture Amp's AI is focused primarily on engagement analytics by surfacing trends, flagging themes in survey responses, and offering a general coaching chatbot. These are useful for HR leaders interpreting data, but the experience still requires HR to do a lot of the connecting work themselves.
15Five's answer to that is AMAYA, its AI thought partner for people insights. HR leaders can ask plain-language questions about performance, engagement, or retention and get clear, data-backed answers immediately, without building reports or interpreting raw metrics.
AMAYA brings together engagement, performance, turnover, compensation, and adoption data in a single connected experience. Ask Amaya why a team's engagement scores dropped, and you’ll see what the performance data shows, whether there are retention signals, and where to focus next.
The Insights Dashboard works alongside AMAYA to surface guided data stories that explain not just what's happening but why, with recommended next steps built in. The goal is to spot risks early, before disengagement becomes a resignation.
Together, AMAYA and Kona represent a complete AI layer that serves HR leaders who need strategic clarity and managers who need practical, in-the-moment support, working from the same underlying data rather than operating in separate silos.
When service and support matter throughout the relationship
Culture Amp's support model leans on an AI help site with no live human chat available. A dedicated Customer Success Manager is only included at enterprise-level spend. For HR leaders who need responsive support during implementation, review cycles, or platform changes, that model creates real risk, particularly if the CSM relationship changes after go-live.
15Five is built to provide more accessible support throughout the user journey using the Right Expert, Right Time model, for all organizations.
Where 15Five is the right choice
Culture Amp started as an engagement tool and has expanded from there. 15Five was built from the start to connect performance, engagement, retention, and compensation into one system that drives action. That difference shows up in how the analytics work, in how managers are supported, in how talent decisions get made, and in how AI is applied across the platform.
15Five is the stronger fit when your goals include more than engagement measurement, when you're trying to build better managers rather than just measure them, when compensation decisions need to be connected to performance data, and when you need AI that gives you answers, not just numbers.
15Five is designed for the HR leader who needs a complete performance management ecosystem that works together as one connected platform.
