ROI Playbook Methodology, not marketing

Here's exactly how
we calculate your ROI.

PURIST is a young agency, so we won't pretend to have hundreds of verified case studies yet. What follows instead is the actual methodology: real workflow architecture, the real tool stack, and the exact calculation behind every figure, built from the same math we use on every free audit call.

Every scenario below is illustrative, modeled from typical time costs and industry patterns, not a claim about a specific existing client. See our full ROI methodology guide for the formula itself.

Figures are modeled estimates using our standard ROI calculation (frequency × time cost × fully-loaded hourly rate, minus setup and maintenance cost), not measured averages across an existing client base. Your actual numbers depend on your specific process, team size and tooling, exactly what a free audit calculates precisely. See the full methodology.

What we design for

Targets built into every workflow we scope.

These are design targets based on the specific processes involved, not a claim about a historical client average.

~95%

<5 min

target response time for lead capture and routing workflows, versus a typical multi-hour manual baseline.

20h+

commonly recoverable per team per week once the highest-frequency manual tasks are automated.

Response-time and data-entry-reduction benchmarks reflect commonly cited industry patterns for lead response and process automation; see our ROI methodology guide for sourcing and how we apply these to your specific case.
