Most growth-services providers force one model. Either you own everything and operate it yourself (DIY-flavoured agencies), or the agency holds the keys and you rent access. Neither serves a solo expert who wants the operating leverage of a managed service AND the asset ownership of a self-built one.
The Two-Track Model resolves this by making the choice explicit. Track A — Client-Owned Infrastructure. Every account is in your name from day one. Hostinger, Mailerlite, Apollo, Cal.com, your domain, your Meta Business Manager. You pay vendors directly. IGP operates as a user-tier seat. You can revoke our access at any time and keep everything running. Default for regulated professions (lawyers, financial advisors, therapists with PHI considerations).
Track B — Turnkey Managed Infrastructure. IGP registers and runs the accounts on your behalf. One invoice covers the retainer plus the underlying subscriptions. You do not manage the vendor relationships during the engagement. The Transfer Guarantee, signed into the contract, covers the migration of every account to your name when you choose. Default for late-career-pivot clients and clients who explicitly want zero operational overhead in the first six months.
Both tracks deliver the same growth system, the same Five Promises, and the same 90-Day Pipeline Guarantee. The difference is only the ownership architecture during the engagement. Most clients pick Track A. Some start on Track B and migrate to A around month nine.
