Compare/Head to head
Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.
Starting price
$4/user/mo
Manager effectiveness platform: check-ins, engagement, and reviews. Paid Engage starts at $4/user/mo billed annually.
Where 15Five fits
$8/employee/mo
Peoplebox combines a Slack and Teams based performance platform (reviews, OKRs, 360s, engagement, compensation) with Nova, an AI recruiter that runs phone screens and interviews. Performance Management starts at $8 per employee a month billed annually, so it suits growing companies that want reviews and goals in one place, with AI hiring available if volume roles are a pain.

Stands out: The $4 Engage seat is a real public number, with manager coaching, Kona, and compensation sold as add-ons rather than hiding the whole suite behind a quote.
Watch out: AI reviews, AMAYA, 360s, and OKRs sit on Perform ($11/user/mo) or Total Platform ($16/user/mo), and Kona/compensation are extra. Budgeting Engage alone will not cover a full performance cycle.
Not the right fit for
Peoplebox
Stands out: Most of the work happens inside Slack or Microsoft Teams, which drives adoption without training, and OKRs can update automatically from tools such as Jira. It is also one of few performance platforms with its own AI recruiter: Nova runs natural phone screens, async video and proctored coding rounds.
Watch out: The $8 starting price covers Performance Management only. 360 feedback is another $8 per employee and compensation $5, so a full stack can pass $20 a person, billed annually. Nova is quoted separately, interviews are English only for now, and reviewers say some AI meeting prompts feel generic.
