Conservative ROI Estimate
Based on Standish Group Chaos Report 2023 (external source), not our own unvalidated claims.
Without PROTHEUS
Average cost of failed project (Standish Group 2023)
With PROTHEUS (Professional)
Annual cost (€49/mo × 12 months)
Break-Even Analysis:
Conservative scenario:Prevent 1 failed project per year (€20K loss) = ROI 3,300%
Realistic scenario:Prevent 2 failures per year (€40K-€200K losses) = ROI 6,700%-33,900%
Break-even:Catching just 1 fatal flaw per year pays for Professional plan 34x over.

Pricing FAQs
What happens after 3 free projects?
Your free quota resets every month. You can analyze 3 projects in January, 3 more in February, and so on—forever. No trial expiration, no credit card required. If you need more than 3/month, upgrade to Professional (20/month) or Agency (unlimited).
Do free projects have feature limits?
No. Free projects get the exact same analysis as paid plans: complete 30-50 page report, 6-8 ADRs, 30-80 user stories, 9 validation rules, budget validation, risk assessment. The only difference is quantity (3/month vs 20/month vs unlimited) and export formats (free = PDF only, paid = PDF + Markdown + JSON).
Can I cancel anytime?
Yes. No contracts, no commitments. Cancel from your dashboard with 1 click. You'll keep access until the end of your billing period. No refunds for partial months, but you can downgrade to Free immediately if you prefer.
Is there an annual discount?
Yes. Pay annually and save 20%:
• Professional: €470/year (save €118) — €39/month equivalent
• Agency: €1,910/year (save €478) — €159/month equivalent
What if I need more than 20 projects/month?
Upgrade to Agency (unlimited projects). If you need 100+ projects/month with team collaboration, white-label reports, and API access, Agency is the best fit. For 500+ projects/year with SLA guarantees and dedicated support, contact sales for Enterprise pricing.
Do you offer refunds?
14-day money-back guarantee on all paid plans. If you're not satisfied within the first 14 days, email hello@protheusai.com for a full refund. No questions asked. After 14 days, no refunds for partial months, but you can cancel anytime.
