Culture Amp vs 15Five: 360 Feedback Comparison

Quick answer

Culture Amp and 15Five solve different review problems. Culture Amp’s Individual Effectiveness 360 is the stronger starting point when the primary job is development: its support material describes self, manager, co-worker, and direct-report perspectives and explicitly frames the workflow around growth rather than performance evaluation. 15Five is the more natural fit when a team wants formal reviews to sit alongside recurring check-ins, goals, calibration, and talent-review routines.

The important Culture Amp caveat is packaging. Culture Amp’s Perform page uses broad 360 and effectiveness language, but the current service-plan matrix lists Perform and Effectiveness separately. Do not assume that a Perform subscription includes Individual Effectiveness 360; ask for the exact module and contract terms in the proposal. Neither product page, by itself, proves that a workflow will be anonymous, easy to implement, or adopted by managers.

At a glance: Culture Amp vs 15Five

The table below compares the six lenses used throughout Best 360 Tools. “Confirmed” means the cited vendor material describes the workflow; it does not mean the experience or outcome has been independently tested. Where a detail could change the buying decision, the row stays qualified or requires a demo check.

How the 360 workflow differs

Culture Amp: development-first Effectiveness 360

The Culture Amp support FAQ describes Individual Effectiveness 360 as a development and growth workflow, not a performance-evaluation workflow. It documents feedback from the employee, manager, co-workers, and direct reports, with employee-driven or coach/admin-supported launch options and grouped feedback. That makes it a compelling fit for a structured development conversation where the review purpose needs to be kept separate from compensation or appraisal.

The trust boundary matters. The same FAQ qualifies confidentiality: a small reviewer group or a specific example can make a contributor identifiable. Treat that as a design constraint, not as a promise of anonymous-by-default feedback. Ask which roles can see raw comments, how small groups are handled, and what a manager or administrator can export.

Culture Amp’s package boundary is equally material. Its Perform page markets continuous feedback, performance reviews, calibration, goals, and development, while the service-plan matrix lists Perform and Effectiveness as separate products. The public material therefore supports the existence of the Effectiveness 360 workflow, but not the assumption that every Perform customer receives it. The current module, contract period, and included services belong in the proposal and contract review.

15Five: formal reviews attached to manager routines

15Five’s Best-Self Review overview documents configurable self, manager, peer, and upward review combinations. It also places Performance Reviews alongside lifecycle reviews, calibration, Talent Matrix, goals, and reporting, with connections to earlier check-ins and reviews. That is a useful model for teams that want a formal review to be one event in a recurring manager cadence rather than a separate annual survey.

The sharing step deserves a deliberate test. The feature overview says results are not automatically shared when a cycle ends, and its supporting settings cover nomination approval, peer and upward identity visibility, and who may remove answers before sharing. Those controls can support a staged review process, but they do not answer every question about anonymity, free-text exposure, or exports. Configure a cycle with the exact reviewer groups and make the vendor show what each person sees before and after sharing.

Category verdicts

There is no universal winner. The category decision depends on the job the review must do and on whether the package and visibility rules survive your policy review.

Best for development-focused 360: Culture Amp

Culture Amp is the stronger fit when the review’s primary job is development and growth, with multiple feedback perspectives. Confirm that Effectiveness 360 is included in the proposed subscription.

Best for manager routines and coaching cadence: 15Five

15Five is the stronger fit when formal cycles need to connect to check-ins, goals, calibration, and talent review. Validate manager adoption with a real cycle.

Trust and result-sharing governance: neither by default

Culture Amp qualifies confidentiality, while 15Five documents staged sharing and identity settings without establishing every anonymity rule. Test raw comments, small groups, and exports.

Commercial clarity for a mixed suite: verify both proposals

Culture Amp’s Effectiveness/Perform boundary and 15Five’s Perform/Total requirement both make module scope important. Neither is a commercial winner until the proposal is specific.

Buyer profiles

Growing companies

Choose 15Five when the immediate operating problem is creating a repeatable manager rhythm around check-ins and formal reviews, and choose Culture Amp when the immediate problem is running a focused development 360. A smaller team should not buy either on feature breadth alone: ask who will configure the cycle, what happens when a reviewer group is small, and whether the proposed package adds administrative overhead.

Mid-market teams

Mid-market HR teams often need both a credible feedback process and enough governance to explain result visibility. Culture Amp’s development boundary can be useful when 360 is intentionally separate from appraisal; 15Five’s connected check-ins, goals, calibration, and talent-review surfaces can be useful when managers already operate in that cadence. Compare those workflow choices against the current service plan, seat scope, implementation support, and data policy rather than treating either product’s package as implied.

Enterprise organizations

For an enterprise rollout, make the decision a governance and operating-model review. Culture Amp may fit a development-led 360 program, while 15Five may fit an established manager-review system that needs connected check-ins and calibration. The cited public records do not establish implementation scale, integrations, data residency, support levels, or contract concessions, so enterprise buyers should keep those points explicitly verify until they are demonstrated and written into the proposal.

Questions to ask in a demo

1. In Culture Amp, is Individual Effectiveness 360 included in the proposed Perform plan, a combined plan, or a separate contract? Show the current plan document and renewal terms.
2. In 15Five, which package unlocks the exact Best-Self Review, calibration, Talent Matrix, reporting, and integrations in scope?
3. Configure one cycle with self, manager, peers, and a direct report. Who nominates, approves, removes, and finally sees each response?
4. Show what happens when a reviewer group is small or a comment contains a uniquely identifying example. Is the response grouped, redacted, withheld, or visible to an administrator?
5. End the cycle without sharing results. What can the manager edit or remove, what does the employee see, and what can be exported?
6. Change a reporting line or miss a deadline mid-cycle. Which reminders, approvals, and audit details persist?

Other options to consider

FeedbackPulse is worth a look when the brief is a lighter peer-feedback process rather than a full development or performance suite. Its public Peer Reviews page describes anonymous-by-default peer reviews, custom text and rating questions, question snapshots, optional review-cycle linking or ad-hoc reviews, response shuffling, reminders, and aggregated reporting after at least two anonymous peer reviews for a reviewee. Its solutions overview and growing-companies page provide broader marketing context, but those pages are not independent user evidence.

That profile can suit a team that wants to start with a bounded peer-feedback cycle and decide later whether it needs the wider governance and calibration surface of a performance suite. It is not a substitute for Culture Amp’s development-focused Effectiveness 360 or 15Five’s connected review routines on the evidence cited here. Verify employee nomination, calibration, reviewer visibility, reporting depth, exports, and implementation support before choosing it.
