Workday + Lattice + Greenhouse + Culture Amp.
Four people-ops taxes. One rebuild.
The standard enterprise HR stack typically costs $600K–$3M+/yr at mid-to-late stage — and 75%+ of that is wrapper margin over commodity primitives (Postgres, payroll APIs, simple workflow). We rebuild all four on direct billing in one bundled engagement. Payroll provider stays · auditors keep working with familiar GL · your HR data lives in your AWS. One project. One contract. One unified HR workspace.
$200M ARR · 1,500 employees · full HR stack
At 5,000+ employees, Y1 reclaim crosses $2.5M. Above 15K employees, often $6M+.

Four wrappers. All wrap simple primitives.
Workday → custom HRIS
Wraps Postgres + workflow + reporting + payroll integration. Per-employee tax + per-module tax.
Lattice → custom perf module
Wraps Postgres + simple workflow + survey logic. Per-employee tax for review cycles + 1:1s + goals.
Greenhouse → custom ATS
Wraps Postgres + Kanban + email + scheduling. Per-employee tax for pipeline + scorecards + offers.
Culture Amp → custom surveys
Wraps Postgres + survey engine + dashboards. Per-employee tax for engagement surveys + benchmarks + reporting.
Bundled engagement amortises rebuild costs across 4 tools — net Y1 reclaim is greater than the sum of separate rebuilds. Plus shared infrastructure: one Postgres serves all four modules (HRIS + perf + ATS + engagement); one identity layer; one audit log; one analytics dashboard.
Why all four at once beats four sequential.

Most teams start with Workday (sharpest math, foundational data) and add Lattice + Greenhouse + Culture Amp within 6 months. Bundle pricing applies if all four commit within 6 months.
