§ 03Manifesto

What doesWorkstack cost?

Invoice50 employees
Market standardfrom €350/mo.
Workstack€80/mo.

~ €3,240 / year saved(40 employees × €2, 10 free)

€2per employee
per month
from employee 11 — free before that

We charge €2 per employee per month. Other vendors charge €7–13. With 50 employees you pay us €80 per month — elsewhere from €350. With 250 employees €480 per month — comparable plans on the market start at several thousand euros there.

Workstack scales with you — from solo founder to 200-person company. Under 10 employees completely free. That covers the entire micro-business segment and gets you into the software before you need it.

From employee 11 onward you pay €2/employee/month — regardless of whether you're 15 or 250. No setup fee, no plan tricks, no premium features behind paywalls. What expensive competitors hide in „Plus" plans is standard with us.

Fair at every size: up to 10 employees Workstack is completely free — no trial, no trick. That covers most founding teams in the first one to two years. As you grow, we grow with you — at a fair €2/employee, with no new contract tiers or volume markups.

Honest deal. One number, one plan, all features. Otherwise we wouldn't have built it.

— Barry, Workstack co-founder
§ 04Security

Personal data is not marketing material.

We're building an HR product for the German-speaking market — from three-person startups to established companies. Which means: data protection isn't a „compliance checkbox" but an architectural decision. Here's what that means in practice.

Frankfurt hosting

Database and storage in Frankfurt am Main. No US servers, no SCC acrobatics.

AES-256 field-level

Sensitive fields (bank details, IBAN, social-security number) are encrypted field by field.

Magic-link auth

No passwords to forget. Login via email link, sessions via HTTP-only cookie.

GDPR Art. 30 audit log

Every access to personal data is logged. Auditor-ready.

Multi-tenant isolation

Postgres row-level security per tenant. No cross-tenant data leaks possible.

Data export anytime

ZIP with all employee data + documents. No lock-in, no waiting room.

You only need two minutes.

Create your company, click the magic link from your email, invite employees. Your employee record is ready in the same breath.
