The Verdict
Intercom is built for saas companies and startups, with a focus on messenger and ai-bot. Proton targets privacy advocates and journalists and leads with encrypted-email and vpn.
On pricing, Proton is the clear winner for budget-conscious users — starting at $3.99/mo compared to $39/mo for Intercom. That $35.01/mo difference adds up quickly for growing teams.
Proton has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Intercom requires a paid subscription from day one.
Feature-wise, Proton offers broader built-in capabilities (7 features vs 6), while Intercom takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
