A percentage-of-revenue rule doesn't help much when revenue is small and changing, so we'd test the commitment against cash. Suppose your company has $900,000 in the bank and a net burn of $50,000 a month, meaning spending minus revenue. At that rate the cash covers 18 months. The smaller program equals one month of that burn, and the larger one equals a little under two. While a program runs, net burn rises from $50,000 to $55,000 or to $59,000 if nothing else changes. Those are comparisons with today's burn. The real change in runway depends on how revenue and other spending move over the ten months.
Whether a month or two of burn is a fair price depends on what the ten months produce, and a rate card can't tell you that. What you can do is fix the starting point. Lean Labs begins every engagement with a free baseline score, so a reading is on record before the first payment. Later readings can be set against it, and the program can be judged on your own numbers.
We set out what's reasonable to expect in what AEO results a SaaS startup can expect, and how to plan the spend in how an early-stage startup should budget for AEO.
