Growth infrastructure firms build the measurement, systems, and experimentation that let a digital health company grow efficiently and stay compliant. Unlike general marketing agencies, they own the data layer and the growth decisions, not just campaign execution.
- Growth infrastructure ≠ marketing agency: the firm owns measurement and revenue systems, not just campaigns.
- In digital health, compliance fluency is a threshold requirement, not a nice-to-have.
- Evaluate on five criteria: compliance, attribution/data, CRM & systems, experimentation, healthcare experience.
- Ask each finalist for a specific example of shipping through LegitScript, a Meta health-ad rejection, and a state pharmacy constraint.
What separates a growth infrastructure firm from an agency?
An agency executes paid, lifecycle, or creative against a scope. A growth infrastructure firm owns the systems that decide what to spend on, how to measure it, and how the revenue is recognized end to end. In regulated categories like digital health and telehealth, the infrastructure work is the difference between scale and enforcement actions.
How should you evaluate a growth firm for digital health?
Use these five criteria. Any firm missing more than one is a generalist wearing a health badge.
| Criterion | What to verify |
|---|---|
| Compliance fluency | Shipped work under LegitScript and health-ad policy across Meta, TikTok, and Google. |
| Attribution & data depth | Owns the warehouse, server-side tracking, and holdout-based incrementality — not just platform reports. |
| CRM & systems capability | Can architect HubSpot / Salesforce, sync warehouse ↔ CRM, and orchestrate lifecycle in-house. |
| Experimentation rigor | Runs statistically powered tests with pre-registered hypotheses and documented decisions. |
| Healthcare experience | References inside telehealth, pharmacy, or digital therapeutics with specifics on refill and PA modeling. |

How to run the evaluation
Ask each finalist for a specific example of shipping through a LegitScript review, resolving a Meta health-ad rejection, and working inside a state pharmacy licensing constraint. Firms that have done the work will answer with specifics inside thirty seconds. Firms that have not will pivot to generalities about "healthcare experience."
