15Five

I tested 15Five for a 180-person SaaS company that wanted to consolidate weekly check-ins, quarterly performance reviews, and engagement surveys onto one platform. The HR team had been running check-ins through a Notion template, reviews through a Google Form, and engagement via Culture Amp every 6 months, which created data silos and review prep took 12 hours per cycle per manager.

The weekly check-in template (priorities for the week, blockers, mood rating, kudos for teammates) felt lightweight enough that submission rate climbed to 78 percent within 4 weeks, vs the Notion template that was running at 41 percent. The objectives tracking module tied weekly priorities to quarterly objectives without forcing OKR rigidity, which the engineering team preferred. Performance reviews used a 360-degree template (manager review, self-review, peer feedback from 3 selected reviewers) and the calibration session view showed all direct reports in a grid for the VP to compare ratings. Engagement survey ran quarterly with eNPS plus 8 driver questions, and the heatmap by department plus tenure surfaced an unexpected dip in the Customer Success team that prompted a 1-on-1 followup.

Setup of the performance review cycle took 4 hours to configure properly - the workflow has 7 steps (template, audience, calibration, manager reviews, peer feedback, calibration meeting, finalization) and missing any one step caused the cycle to skip people. Integrations with Slack and BambooHR worked but the Slack channel notifications for weekly check-in reminders fired at 9 AM UTC instead of respecting user timezone, so the Asia-Pacific team got pings at 5 PM local time. Pulse surveys allowed only 5 questions per pulse, which was too few for a proper diagnostic on a specific topic without combining 2 pulses into one. Pricing jumped from 8 USD per user per month for Engage tier to 16 USD per user for Perform plus Engage combined, which doubled the cost when the team needed both.

Verdict: pick 15Five when the company is 50-500 employees and needs weekly check-ins plus performance reviews plus engagement together on one platform. Pick Lattice S152 when calibration plus succession planning plus compensation review are first-class needs - Lattice has deeper review workflow with calibration matrix. Pick Culture Amp S178 when engagement survey science and benchmarking against industry are the priority over check-ins. Gusto S180 for HRIS plus payroll, Rippling for global payroll plus device management, both adjacent not directly competing.
