Exploring different paths

I am exploring a few acquisition paths and wanted to sanity check both feasibility and investor appetite. Path 1: Partner model. Two partners acquire a business. One becomes the full time CEO running day to day operations. The other focuses on systems, automation, operational improvements, and future acquisitions. Equity is split within the operator pool rather than a traditional small operating partner stake. Path 2: Holdco model. Acquire a solid business around $1M to $3M EBITDA, operate it, stabilize systems, install a strong GM, then pursue additional acquisitions under a holding company. Path 3: Rollup model. Acquire a platform company first, then buy smaller tuck ins in the same industry and integrate them. Questions for those who have done deals: Are investors generally open to the partner model where one operator is CEO and the other focuses on systems, strategy, and scaling while still holding meaningful equity? For first time buyers, is the holdco path typically more realistic than attempting a rollup early? Trying to understand what structures investors are most comfortable backing.
