Published prices start at about $4 per seat per month: Lattice charges $4 for its Engagement module and 15Five charges $4 for its Engage plan, both billed annually. The figure to watch is not the per-seat rate but the annual minimum. Lattice applies a $4,000 annual minimum spend, so a company under roughly 85 seats pays the floor rather than the rate, and Quantum Workplace states a $15,000 annual minimum, which rules it out for most companies under 300 employees. Workleap Officevibe starts at $4,999 a year.
Around half the market publishes no price at all. Culture Amp, CultureMonkey and Qualtrics are quote-only, priced by headcount, by number of employees surveyed, or by planned usage. Nearly every vendor in this category bills annually, so the practical question is what you are committing to for a year rather than what it costs per month.
