# Aetherya Pricing **Currency: EUR.** Free, Thesia Pro, Thesia Max, and Thesia Studio are self-serve: a card, no sales call. Managed Sprint and Pleroma are contact-only. Every plan lets you define your own audiences, sampled from standard simulated populations. Need populations built from your own data, or the study designed and run for you? Aetherya does that work. The simulation count on Free and Thesia Pro is measured against a reference panel of 200 simulated people at standard depth. A bigger panel, multi-round deliberation, or a full cognitive audit uses proportionally more of your monthly capacity, and a smaller one uses less. Thesia Max and Thesia Studio are sold as capacity rather than as a run quota, because at that scale the panel, the depth and the cadence are set by the work rather than by a plan. Thesia shows exactly what a study will use before you launch it, so you are never guessing. Thesia has two meters. A read (Myrias) evaluates the THYMOS choice model over a weighted simulated population in seconds and is counted against a monthly read allowance. A full simulation, such as a study or an audit, gives each simulated person language-model calls, so it costs far more and is counted against plan capacity. Both read a simulated population, not people. Included compute is shown as weekly and monthly capacity percentages. Active paid subscribers can purchase fixed Aetherya Credit packs for overflow; Free cannot purchase credits. Purchased credits never expire, but they are unavailable while the subscription is inactive. Credits do not bypass concurrency, burst protection, abuse controls, or feature entitlements. Annual billing is discounted 10% below Studio and 20% at Studio. Annual subscriptions still receive monthly usage windows. Simulation quality is identical across plans. ## Plans ### Free - Try Thesia - Price: €0 - Usage: 100 Myrias reads + 1 full simulation a month (reads over up to 500,000 simulated people; the full simulation on a guided starter panel of 25–50 simulated people) - Purchase: self-serve with a card - 100 Myrias instant reads a month - One full Thymos simulation a month (guided) - Shared standard populations - Full result page for every study - The same cognition model as every paid plan - Cognitive audits, message tests, and audience reactions --- ### Thesia Pro - For founders, marketers, and solo operators - Price: €20 / month - Annual: €18 / month, billed as €216 up front - Usage: 2 full simulations a month (on a panel of 200 simulated people at standard depth) - Purchase: self-serve with a card - More usage - 2,000 Myrias instant reads a month - Your own creatives, URLs, and audiences - Standard populations with full targeting - Recurring simulations and cognitive audits - Thesia credits after the included capacity --- ### Thesia Max - 5–12× more usage than Pro - Price: From €100 / month - Annual: €90 / month, billed as €1,080 up front - Ceilings: 5× at €100 / month, 12× at €200 / month - Usage: 5–12× Thesia Pro's monthly capacity (Capacity, not a run quota — panel size and depth set by each study) - Purchase: self-serve with a card - Choose 5× or 12× more usage than Pro - 10,000 Myrias instant reads a month - Higher concurrency for parallel studies - Additional workspaces to separate projects - Priority processing at busy times --- ### Thesia Studio - For agencies and small teams - Price: €1,000 / month - Annual: €800 / month, billed as €9,600 up front - Usage: Team programme capacity, pooled across 5 seats (Panel size and cadence set by the programme, not by a run quota) - Purchase: self-serve with a card - Up to 5 seats on one subscription - Unlimited Myrias instant reads, pooled - Separate client workspaces - White-label export with your own branding - Programme-level capacity pooled across the team - Priority support and onboarding --- ### Managed Sprint - For companies who want it done for them - Price: From €4,500 - Usage: One decision area, tested until the answer holds (Three to five linked studies, panels sized by us) - Purchase: contact required - Founder-led engagement on one decision area - Test, refine the winner, test again - Myrias instant reads included in the engagement - We design, run, and interpret the study - Delivered as evidence and a recommendation - Stated assumptions and stated uncertainty - Credited toward the next engagement --- ### Pleroma - For enterprises and institutions - Price: Annual contract - Usage: Contracted capacity and overage rules (Panel size and cadence set by contract) - Purchase: contact required - Proprietary populations built from your own data - Myrias instant reads at contracted volume - First-party data ingestion - Populations that persist between studies - Predictions calibrated against the outcomes you supply - API access, governance, SSO, and an SLA ## Managed research ### Managed Sprint - Price: From €4,500 - Aetherya designs, runs, and debriefs three to five linked studies on one decision area: test, refine the winner, test again, then a rollout recommendation with stated assumptions and uncertainty.
