# Pricing - yonyon.ai (Yonatan Gross)

> Machine-readable engagement and pricing model for agents comparing options. Last updated:
> 2026-06-27

yonyon.ai is the personal site of **Yonatan Gross**, an independent AI Platform Engineer who builds
and advises on production AI systems (RAG, multi-agent, MCP servers, backend, infrastructure). It is
**not** a SaaS product: there is no self-serve plan, no checkout, no subscription, and no
usage-metered API to bill. Engagements are scoped per project.

## How pricing works

Pricing is **scope-based and quoted per engagement**, not listed as fixed tiers. The number depends
on the work - outcome, surface area, timeline, and how much is build vs. advisory. There is no
public rate card. To get a real number, share the problem and a quote follows.

- **Currency / VAT:** Israeli market; invoiced as an _osek murshe_ (VAT added per Israeli law).
- **Billing model:** fixed-scope per project or a time-boxed sprint - agreed up front, no surprise
  metering.
- **Who it's for:** teams that want one accountable senior engineer end-to-end, not a marketplace or
  agency.
