Requirements to minimum viable plan to cost
Momen doesn't give a vague quote: it first sizes the project's actual demand for each capability and resource, then costs each item out.
The numbers in the "Project demand" column below — their scale assumptions and derivations — are detailed in Scale & sizing.
Minimum viable plan
PRO
No project details (type, description, or user stories) were found in the database. Without specific requirements for branding, payments, or advanced workflows, the FREE plan is sufficient for initial exploration or basic display.

Servers, databases, traffic and storage are inherent infrastructure costs for this project — you pay them whether you outsource, use Cursor or Lovable, or build it yourself (self-built runs ≈ $441/mo at AWS list prices, often more), plus the extra dev and ops staff. Momen bundles all of it into $368/mo all-in and removes the need for an ops team.
The frontend can be generated with AI tools (Cursor, Lovable, etc.); the hard part is the backend — auth, database, scaling, data security and ops. Momen delivers a production-grade backend as a BaaS: keep the vibe-coding speed on the frontend, while the backend runs on proven infrastructure — reliable, with no self-hosting or ops.
What scale this estimate assumes, and how the numbers are derived
Cost depends heavily on usage volume. First see the key assumptions and business scenarios this estimate uses, then the full calculation derived from each scenario for every resource — all adjustable to your real situation.
We estimate the platform to have 1,000 active coaches and a 50:1 client-to-coach ratio, resulting in 50,000 clients. Including anonymous visitors browsing the catalog, the total user base is estimated at 51,000.
This is a standard linear-growth SaaS product. We assume a 225-day effective accumulation period as it reflects a mix of early-stage growth and current steady-state data production over a 12-month window.

times/month
This scene represents the high-activity window every evening when clients perform their workouts. We assume a 4-hour (14,400s) window daily (30 occurrences/month) based on typical fitness app usage patterns where users train before or after work. This period captures the bulk of video consumption and progress tracking.
