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

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.

Head-to-Head: AI Features

AI Capability	Lattice	15Five	Culture Amp
Review drafting	✅ Best	⚠️ Basic	⚠️ Basic
Engagement analysis	✅ Good	⚠️ Basic	✅ Best
Turnover prediction	⚠️ Basic	❌ No	✅ Best
Manager coaching	⚠️ Basic	✅ Best	⚠️ Basic
Goal suggestions	✅ Good	⚠️ Basic	❌ No
Action plan generation	⚠️ Basic	✅ Good	✅ Best

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.
