Funding incrementality experiments sustainably requires strategic budget planning. Here are general strategies that enterprises often apply:

1. Allocating Budget Percentage: Some businesses allocate a specific percentage of their overall marketing budget to experimentation. The exact percentage can vary, depending typically on the industry, business maturity, and risk tolerance.

2. Phased Funding: Start with a small-scale pilot, assess performance, and roll out in phases. So, rather than investing a massive amount upfront, enterprises gradually fund the efforts based on success metrics.

3. Performance-Based Reallocation: Some enterprises may reallocate budget from less effective initiatives towards incrementality experiments, adapting as they learn what works best for their market and audience.
