The Operating System

The FlexOS stack is what makes the lifts repeatable.

The numbers above are not the product of one-off campaigns. They come from a 90-day cadence — instrumentation, experimentation, lifecycle, paid acquisition — running on a shared growth stack called FlexOS, shipped into every client account within 14 days of kickoff.

Read the FlexOS overview
  1. 01

    Instrumentation week

    Every engagement starts with a single source of truth. We consolidate attribution across paid, organic, lifecycle, and product-usage events into one FlexOS dashboard. No more arguments about which dashboard is right.

  2. 02

    Experimentation cadence

    140+ pre-built experimentation templates ship into client accounts in the first 14 days. From week three we run a continuous test cycle — typically 8 to 12 concurrent experiments, reviewed weekly against pipeline, not vanity metrics.

  3. 03

    Lifecycle instrumentation

    Lifecycle messaging is wired to product-usage signals, not just demographic scores. We map the activation event for every segment and route expansion intent to sales within 72 hours of signal capture.

  4. 04

    Fixed-fee, performance-aligned

    40% of every GrowthFlex fee is tied to qualified pipeline targets. No hourly retainers, no scope creep. Monthly performance readouts against the baseline we set together in week one.

“We came to GrowthFlex with a stalled ABM motion and rising CAC. Ninety days in we had a 3.1× pipeline lift and a self-serve funnel that actually converted into sales pipeline. The audit alone was worth the engagement.”

Priya Ramaswamy Chief Marketing Officer, Northwind HR (Series B) San Francisco, March 2024
