Compensation
Proton publicly advertises competitive salary, equity, and additional rewards. Specific salary bands were not established from the reviewed public sources; job postings also mention health coverage, retirement options, leave, wellness support, and commuting support.
Benefits
Pricing
Freemium plus paid monthly/annual subscriptions for individuals, families, and businesses; core services have free tiers and premium bundles. Lumo has free access plus paid Plus/Professional tiers.
Differentiators
Estimated revenue
Approximately $20M–$30M annual revenue according to a 2026 third-party company profile; another third-party estimate reported $64.4M 2025 ARR, so public estimates are inconsistent and should be treated as directional.
Proton announced Lumo private AI and said legal uncertainty over proposed Swiss mass-surveillance rules was prompting movement of most physical infrastructure out of Switzerland; Lumo would move first and the investment in EU infrastructure exceeded €100 million.
SourceProton reportedly froze new Swiss investments over proposed surveillance regulations, with planned AI infrastructure in Germany and Norway; Proton later clarified this was a targeted infrastructure adjustment rather than a confirmed corporate exit from Switzerland.
