I spent two weeks demoing Lattice, 15Five, and Culture Amp for a mid-size company that was drowning in spreadsheet-based performance reviews. All three platforms promised AI-powered performance management. The reality? They’re very different tools solving different problems.

Here’s the honest comparison.

Quick Overview

Feature	Lattice	15Five	Culture Amp
Best for	All-in-one HR platform	Manager enablement	Employee engagement
Company size	50-5,000	50-1,000	200-10,000
Starting price	~$11/person/mo	~$4/person/mo	Custom pricing
AI features	Review drafting, goal suggestions	AI-assisted check-ins	Engagement insights, action plans
Free trial	Yes (demo)	Yes (14 days)	No (demo only)

Lattice

What it does well

Lattice is the most comprehensive platform of the three. Performance reviews, goals/OKRs, engagement surveys, compensation management, and career development: all in one place. Their AI features focus on helping managers write better reviews faster.

AI highlights:

• AI-generated review draft suggestions based on goals and feedback
• Sentiment analysis on engagement survey responses
• Automated goal suggestions based on role and department
• AI-powered career pathing recommendations

Where it falls short

It’s a lot. For smaller teams, Lattice can feel like buying a Swiss Army knife when you just need a screwdriver. The setup takes weeks, not days. And at $11+/person/month, it’s the most expensive option for what many teams actually use.

My take: If you need one platform for everything HR-related and have the budget, Lattice is hard to beat. If you mainly need better performance reviews, it’s overkill.

15Five

What it does well

15Five is built around a simple idea: managers should check in with their team weekly, not annually. The platform centers on weekly check-ins, 1-on-1 agendas, and continuous feedback. It’s the most manager-friendly of the three.

AI highlights:

• AI-suggested talking points for 1-on-1s based on recent check-ins
• Sentiment detection in weekly check-in responses
• AI-generated review summaries from accumulated check-in data
• Engagement pulse analysis with trend detection

Where it falls short

It’s lighter on the traditional HR features. No built-in compensation management. The engagement surveys are basic compared to Culture Amp. And if your managers don’t actually do the weekly check-ins, the whole system falls apart.

My take: The best tool for companies that believe in continuous feedback over annual reviews. At $4/person/month, it’s also the most affordable entry point. But it requires manager buy-in to work.

Culture Amp

What it does well

Culture Amp started as an engagement survey platform and it shows: their survey and analytics capabilities are the strongest of the three. The AI features focus on turning engagement data into actionable insights.

AI highlights:

• AI-powered engagement survey analysis with automatic theme detection
• Predictive analytics for turnover risk
• AI-generated action plans based on survey results
• Benchmarking against industry data (their dataset is massive)

Where it falls short

The performance review module feels bolted on: it works, but it’s not as polished as Lattice’s. Custom pricing means you can’t easily compare costs. And the platform is clearly designed for larger companies: smaller teams may find it overwhelming.

My take: If employee engagement is your primary concern and you want the deepest analytics, Culture Amp wins. If you need a complete performance management system, look elsewhere.

Full Pricing Breakdown (2026)

Pricing is where these platforms diverge significantly. Here’s what you’ll actually pay:

Lattice Pricing

Lattice uses modular pricing: you pick the modules you need:

Module	Cost
Performance Management	$11/person/mo
Engagement	+$4/person/mo
Compensation	+$6/person/mo
Growth (career development)	+$4/person/mo

Total if you want everything: $25/person/month. For a 200-person company, that’s $60,000/year. Annual contracts required, and you’ll need to negotiate: list prices are just the starting point.

15Five Pricing

15Five has three straightforward tiers:

Plan	Cost	What’s Included
Engage	$4/person/mo	Engagement surveys, pulse checks, analytics
Perform	$14/person/mo	Reviews, 1-on-1s, OKRs, check-ins + Engage
Total Platform	$16/person/mo	Everything + career development, HR outcomes dashboard

Best value: The Perform plan at $14/person gives you most of what teams need. The jump to $16 for Total Platform is worth it only if you’re serious about career pathing.

Culture Amp Pricing

Culture Amp doesn’t publish prices. Expect:

• Engage only: ~$5-8/person/month
• Perform + Engage: ~$8-10/person/month
• Full platform: ~$10-12/person/month
• Minimum contract: Typically 100+ employees, annual commitment

They price based on company size, modules selected, and how hard you negotiate. Smaller companies (under 200) will pay more per seat.

Price Comparison at Scale

Company Size	Lattice (Performance + Engagement)	15Five (Perform)	Culture Amp (Perform + Engage)
100 employees	$18,000/year	$16,800/year	~$10,800/year
500 employees	$90,000/year	$84,000/year	~$48,000/year
1,000 employees	$180,000/year	$168,000/year	~$84,000/year

Culture Amp’s volume discounts are aggressive at scale. 15Five is cheapest for small teams. Lattice is the priciest but packs the most features per dollar if you use everything.

What’s New in 2026

All three platforms shipped major updates this year. Here’s what matters:

Lattice: 2026 Updates

• AI Review Assistant v3: Now drafts full review paragraphs (not just bullet suggestions) based on goals, peer feedback, and 1-on-1 notes. Quality is genuinely good: managers report 40% less time on review writing.
• Rippling integration: Native two-way sync with Rippling for headcount, compensation, and org chart data.
• Mobile overhaul: Completely rebuilt mobile app: managers can now complete full review cycles from their phone.
• AI-powered career pathing: Suggests lateral moves and skill gaps based on internal mobility data.

15Five: 2026 Updates

• AI Check-in Summaries: Weekly check-ins now auto-generate a manager summary with trends and flagged concerns. Saves 15-20 minutes per direct report per week.
• Gusto integration: Deep payroll sync for performance-based compensation decisions.
• Microsoft Teams native app: Full 15Five experience inside Teams: check-ins, high-fives, 1-on-1 agendas without leaving the chat window.
• Spark AI coaching: AI-generated coaching prompts for managers based on team sentiment patterns.

Culture Amp: 2026 Updates

• Predictive attrition model v2: Now claims 85% accuracy at identifying flight risks 90 days out. Uses engagement + performance + market data.
• Workday bidirectional sync: Real-time sync instead of batch: no more stale org data.
• AI action plan generator: Takes survey results and generates specific, manager-level action plans with timelines.
• Skills-based engagement: New module linking engagement data to skills taxonomy for more targeted interventions.

Common Stacks

These platforms don’t exist in isolation. Here’s what I see teams actually pairing them with:

Lattice + BambooHR

The most common mid-market stack. BambooHR handles core HR (payroll, time-off, onboarding), Lattice handles performance and growth. The native integration syncs employee data, org charts, and employment dates. Works well for 100-1,000 employee companies that want best-of-breed in both areas.

15Five + Gusto

The startup-friendly combo. Gusto handles payroll and benefits for SMBs, 15Five adds continuous performance management on top. The 2026 integration lets managers see compensation data alongside performance data for raise conversations. Best for companies under 200 that want simplicity and affordability.

Culture Amp + Workday

The enterprise play. Workday is the system of record, Culture Amp adds the engagement and analytics layer that Workday’s native tools can’t match. The bidirectional sync (new in 2026) means no more manual data reconciliation. Typical for 1,000+ employee companies already invested in Workday.

Other stacks worth mentioning:

• Lattice + Greenhouse: Performance data feeding into internal mobility and recruiting workflows
• 15Five + Slack: For teams that live in Slack and want performance management to feel lightweight
• Culture Amp + Visier: When you want engagement data flowing into a dedicated people analytics platform

Budget Alternatives

Can’t afford Lattice and Culture Amp feels too enterprise? Here are solid alternatives:

Leapsome (~$8/person/month): European-based, strong on performance reviews and goals. Good GDPR compliance. The AI features are catching up fast. Best for European companies or those who want reviews + engagement without paying Lattice prices.

Betterworks (~$10/person/month): OKR-focused with performance reviews bolted on. Strong for companies that want goals to drive everything. The AI calibration features are underrated.

Trakstar (~$5-8/person/month): Straightforward performance reviews without the bloat. No AI bells and whistles, but solid execution on the basics. Good for companies that just want to replace spreadsheet reviews and don’t need engagement surveys.

Which Should You Choose?

Choose Lattice if: You want one platform for everything: reviews, goals, engagement, compensation, career development. You have 100+ employees and budget for $11+/person/month.

Choose 15Five if: You believe in continuous feedback over annual reviews. Your managers are willing to do weekly check-ins. You want the most affordable option that still has meaningful AI features.

Choose Culture Amp if: Employee engagement is your top priority. You want the deepest analytics and benchmarking data. You have 200+ employees and want predictive insights.

Or skip all three and use ChatGPT if you’re a small team (under 50) that just needs help writing better performance reviews. At $20/month total (not per person), it handles the writing part surprisingly well: you just lose the tracking, analytics, and workflow features.

FAQ

What’s the cheapest option?

15Five at $4/person/month (Engage plan) is the cheapest entry point. But if you want actual performance reviews, it’s $14/person/month. For teams under 50, seriously consider whether you need a platform at all.

Can I use just the engagement module?

Yes, for all three. 15Five’s Engage plan ($4/person) is engagement-only. Culture Amp sells Engage as a standalone module (~$5-8/person). Lattice lets you buy Engagement standalone for $4/person, but their sales team will push you toward the Performance bundle. If engagement is all you need, Culture Amp gives you the deepest insights per dollar.

How long does implementation take?

15Five: 1-2 weeks. It’s lightweight and managers can start using check-ins immediately. Lattice: 4-8 weeks for full deployment (reviews, goals, compensation). Culture Amp: 3-6 weeks, primarily because survey design and benchmarking setup takes time. All three offer implementation support, but Culture Amp’s dedicated CSM approach is the most hands-on.

Do employees actually use these?

Adoption varies wildly. 15Five reports the highest engagement rates (~85% weekly check-in completion) because the ask is small: 15 minutes per week. Lattice sees strong adoption during review cycles but lower engagement between cycles. Culture Amp’s survey response rates average 75-80%, which is strong for engagement surveys. The key factor isn’t the platform: it’s whether leadership actively uses and references the data.

Is AI performance management biased?

Potentially, yes. AI review assistants are trained on historical review data, which contains existing biases (gender bias in language, recency bias, halo effects). Lattice and Culture Amp both publish bias audits for their AI features. 15Five’s AI is more lightweight (summaries, not evaluations) so bias risk is lower. Best practice: use AI for drafting and data surfacing, never for final decisions. Always have humans review AI-generated performance content before it reaches employees.
