15Five vs Lattice (2026): Pricing, AI & Which Fits Your Team

By Harmny Editorial Team · Last updated September 2026

Bottom line

Under 25 people or coaching-first culture: 15Five, with no seat minimum, self-serve setup, and Kona AI's live in-meeting coaching as an add-on. 200+ people with a dedicated HR team: Lattice, with deeper HRIS integrations, compensation management, and a mature engagement suite with industry benchmarks. Both now price modularly rather than at one flat per-seat rate, so the right comparison depends on which modules each team actually needs.

The short version

15Five and Lattice get cross-shopped constantly, and honestly, they shouldn't be as often as they are. They're built for different companies. 15Five is an opinionated coaching tool a 60-person company can run without an HR department. Lattice is an enterprise platform that expects an implementation project, a dedicated HR team, and pricing that scales up fast once you add modules. Most of the "which one?" agonizing dissolves once you know your headcount, your budget for add-on modules, and whether anyone owns HR full time.

Pricing: two platforms, both modular now

Neither vendor sells a single flat per-seat price anymore. 15Five splits into Engage ($4/user/month, pulse only), Perform ($11/user/month, reviews and continuous feedback), and Total Platform ($16/user/month, both plus manager enablement), with no seat minimum. Lattice's core Talent Management module runs $11/seat/month, with Engagement (+$4), Compensation (+$6), and Grow (+$4) as separate add-ons, and a $4,000/year minimum contract commitment in place of the old seat minimum.

For a 12-person team on Lattice's core plan, that $4,000/year minimum works out to about $333/month, close to the floor a 25-seat minimum used to create, so small teams pay for capacity they aren't using either way. 15Five's tiered pricing has no such floor: a 12-person team on Perform pays $132/month with nothing extra. A fully-loaded Lattice deployment across all four modules runs roughly $15-19/user/month once every module is added, so comparing Lattice's $11 headline rate to 15Five's price without accounting for add-ons understates the real cost.

AI: coaching versus documentation

Both shipped headline AI features, and comparing them one-to-one misses what each is for. Kona AI, 15Five's assistant, now a $19/manager/month add-on, works during the live 1:1: it listens and suggests coaching moves in the moment, what to ask next, how to reframe. It's a coach in the manager's ear. Lattice's AI Meeting Agent, launched early 2026, is a note-taker: live transcription, auto-summaries, action items. It makes meetings cheaper to document, not necessarily better to run.

So the question isn't "whose AI is better." It's which problem your managers actually have, and which vendor's add-on price you're willing to carry. Managers who freeze mid-conversation get more from Kona. Managers drowning in follow-up admin get more from the Meeting Agent.

Engagement: check-ins versus benchmarks

This one is less close. 15Five's Engage tier is weekly pulse check-ins, useful as a manager-to-report signal, thin as an analytics product. Lattice's engagement add-on is a mature suite with industry benchmark data built from a large customer base, its real differentiator. If your board asks "how do we compare to peers," Lattice's engagement module can answer that and 15Five's Engage tier can't.

Who should pick which

Pick 15Five if:

• You're a small team (no seat minimum or annual contract floor to worry about)
• You want the strengths-based Best-Self Review methodology
• Live in-meeting coaching (Kona AI add-on) is the draw
• You need to be running this week, not after an implementation

Pick Lattice if:

• You're 200+ with a dedicated HR team
• Deep Workday / Rippling / BambooHR integration is required
• Compensation and merit cycles need to live in the same tool
• Industry-benchmarked engagement reporting is a board requirement

The third option most teams in this comparison miss

Full disclosure, this is our page and our product, so weigh accordingly. But the pattern behind most 15Five-vs-Lattice searches is a 20-200 person team that finds 15Five's higher tiers pricey and Lattice heavy once the add-ons stack up. That's the gap Harmny was built for: $8/user/month on Starter, free up to 10 users, self-serve setup, with the competency frameworks and employee-visible career pathing neither of these two does deeply, plus time off, attendance, onboarding, and compliance in the same tool. The honest trade-offs: no live in-meeting coaching like Kona, and lighter HRIS payroll integrations than Lattice. Details in Harmny vs Lattice, or see the full 15Five alternatives roundup.

Frequently asked questions

Which is cheaper, 15Five or Lattice?

It depends on which modules you need. 15Five sells three tiers: Engage at $4/user/month, Perform at $11/user/month, and Total Platform at $16/user/month, with no seat minimum. Lattice sells modularly: Talent Management (reviews, goals, 1:1s) at $11/seat/month, with Engagement, Compensation, and Grow as separate add-ons, plus a $4,000/year minimum contract instead of a seat minimum. For a small team on Lattice's core plan, that annual minimum works out to roughly the floor a 25-seat minimum used to create. A full-stack Lattice deployment runs roughly $15-19/user/month.

What is the main difference between 15Five and Lattice?

Philosophy and scale. 15Five is a coaching-first performance tool built around the Best-Self Review methodology, self-serve, best for 50 to 1,000 people. Lattice is an enterprise platform with deep HRIS integrations, compensation management, and benchmark-grade engagement analytics, best for 200 to 5,000.

Does 15Five or Lattice have better AI?

They solve different problems. 15Five's Kona AI, now a $19/manager/month add-on, coaches managers in real time during live 1:1s, suggesting what to say as the conversation happens. Lattice's AI Meeting Agent, launched early 2026, transcribes 1:1s and generates summaries and action items. Coaching versus documentation.

Can a small team use Lattice?

Yes, though the $4,000/year minimum contract commitment changes the math for very small teams: a 10-person team on the $11/seat core plan still owes the annual minimum, which works out to well above $11 per actual user. Small teams often get better economics from 15Five (no seat minimum) or from free-tier tools like Harmny or Teamflect.

Is there a cheaper alternative to both 15Five and Lattice?

Yes. Harmny costs $8/user/month (Starter) with a free tier up to 10 users, and covers reviews, goals, 1:1s, competency frameworks, and eNPS engagement surveys with department heatmaps. Harmny's AI features (coaching prep, Org Brain) are on its $16/user/month Growth plan. Workleap (~$5/user) and Teamflect ($0-$5/user) are cheaper still, with lighter feature sets.
