Why are we here?

Tired of analytics tools spawning decks and debates with minimal decisions? Robert's Rules streamlines the search: Curating obscure AI gems from my Meta AI network, providing experiment rules for causal validation and lifts, so marketers can quickly test, scale revenue, and move on when the S-curve flattens. In today's martech landscape, CMOs face a deluge of data—endless insights from attribution models, MMM tools, and vanity metrics like NPS that fuel PowerPoint marathons but yield few actionable wins. Drawing on my 30 years in analytics and Meta AI leadership, this newsletter cuts through the bloat by focusing on causal inference for balancing incremental customer lifetime value (iCLV) against incremental cost to acquire a customer (iCAC) in digital channels. We'll explore S-curves as the key to efficient growth: identifying elastic phases for scaling and flat tails for pivoting. Through curated 2024-2025 sources and practical rules—like diff-in-diff experiments and AI-driven automation—you'll gain tools to turn frustration into focused revenue lifts, ethically and sustainably. Dive in for gems that empower quick testing and real results.

Frustration

Ah, the diminishing marginal return curve. It makes you look like a genius when you are working on the elastic part of the curve, and like Admiral Motti is mocking “your sad devotion to an ancient religion” when the curve shows you were spending money on the flat part.  At Meta, we called them J curves (mainly because we were moving so fast we didn’t get to measure our marketing impact until the channel was already diminishing). At General Motors, we called them “S” curves. With our national campaigns, supplemented by dealers and competitors directly mentioning our trucks in the ads, we spent a lot of time trying to mine the little bit of the y-axis on a very flat upper tail.

Every technology in martech exists in some form or fashion due to these curves. Either to discover these curves (Marketing Automation, Email Marketing, and CRM tools), to draw these curves (Paid Advertising Platforms), to understand these curves (Analytics platforms), to control your spend on these curves (Marketing Mix Modeling Tools), or to ignore these curves (Marketing Attribution tools). Aside from the software, there exists this dangerous little devil on the CMO’s shoulder that whispers, “If you don’t spend the money, finance is going to take it away this year and next year”.

Each channel, product, and VP wants to invest their money independently of the CMO’s portfolio. There is the very real trade-off between short-term investment in sales and long-term investment in developing the brand (for the current product suite and the products yet to come). There are vanity metrics that stroke the CEO’s ego, like the number of people who are optimistic about the brand’s future. There are the metrics that Bain and McKinsey are screaming that you are missing (I’m looking at you, Net Promoter Score).  There is a constant debate over whether conversions (which make up the Y-axis of the S Curve) should be calculated by interested parties, such as the platform (Google, Meta, Adobe, etc.), or by product teams that understand the distribution channels, versus disinterested parties like finance or measurement agencies who might not understand the context of ads.

If you are the CMO…

You just want to spend money where the S curve isn’t flat, so that you are showing measurable results for the company.  How do you do that? An outside observer might conclude that a CMO’s investment strategy is powered by being shown THOUSANDS of slide decks.  Only once the CMO is cocooned in a protective layer of charts, statistics, creative briefs, focus group outtakes, and the most eloquent oratory can their strategy begin to grow into the beautiful butterfly of a “monthly marketing report”.

Diminishing Marginal Returns - the “S”

I’m including a code example below with random data. Please don’t feel intimidated if you are not familiar with Python. You can paste this into an AI and ask it to explain what’s happening at each step. Generate your own S Curve while you read along with this article.  You will need Python 3.10 or later.

import numpy as np
import matplotlib.pyplot as plt


# Set seed for reproducible results
np.random.seed(42)


def smooth_s_curve(x, max_revenue=1400000, growth_rate=0.000006, inflection=350000, baseline=80000):
   """Smooth logistic S-curve for marketing spend vs revenue"""
   return baseline + (max_revenue - baseline) / (1 + np.exp(-growth_rate * (x - inflection)))


# Generate realistic spend data
spend = np.sort(np.random.lognormal(mean=12.5, sigma=0.8, size=150))
spend = np.clip(spend, 0, 1500000)


# Create smooth trend line
spend_smooth = np.linspace(0, 1500000, 500)
revenue_smooth = smooth_s_curve(spend_smooth)


# Add realistic noise to data points
revenue_data = smooth_s_curve(spend) + np.random.normal(0, 25000, len(spend))


# Create clean plot
plt.figure(figsize=(10, 6))
plt.scatter(spend/1000, revenue_data/1000, alpha=0.6, color='steelblue', s=30)
plt.plot(spend_smooth/1000, revenue_smooth/1000, color='crimson', linewidth=3)

The Rules Part…

All kidding aside, the deluge of proposals from inside and outside the company relegates the CMO to pruning their way through fields of data, searching for valuable kernels of truth. Analysts (myself included) share the blame—now that we can measure everything, we do, flooding reports with metrics that obscure real impact on corporate goals. CMOs contribute too, by centralizing decisions like hydroelectric dams, funneling all insights through their "turbines" of execution. So, how can we fix it? Here are three suggestions, each with actionable rules drawn from obscure AI gems. These leverage causal inference to balance incremental gain (incremental revenue is the road, but incremental customer lifetime value, CLV, is the destination) against incremental investment (incremental cost to acquire a customer, CAC) in digital channels, ensuring ethical, scalable lifts.

1. Approve and Measure Marketing Systems, Not Individual Executions

Netflix does some fantastic research; you should be reading their blog if you are not. Their 2021 piece (updated in spirit by recent causal AI discussions) proposes measuring longer-term impacts of short-term experiments on subscriber growth. By designing systems as functions of corporate goals and measuring their production, you reduce micromanagement. For measuring margin contribution (incremental revenue or incremental CLV) versus marginal investment (incremental cost to acquire a customer), this means building learning systems (dare I say, AI systems) that auto-optimize digital funnels (e.g., social ads to email nurturing), using experiments (or quasi-experiments) to validate on S-curve progression.  The Netflix article, by Hamidreza Badri and Alex Kaufman, is summarized here.

From an excellent paper, published last week, "Minimax and Bayes Optimal Best-arm Identification" by Alejandro Rodriguez Dominguez, we draw rules for adaptive designs in treatment choice, perfect for marketing systems selecting "best" channels. This excellent paper focuses on fixed-budget best-arm ID, which is innovative for its two-stage allocation to minimize regret in identifying optimal strategies.

Actionable Rule 1: Pilot Uniform Allocation for System Baseline

• Step 1: Allocate equal budget across 3-5 digital channels (e.g., Google Search, Meta Ads, LinkedIn) for a 2-week pilot, tracking baseline iCAC (cost per acquisition) and early iCLV indicators (e.g., visits, sales, 30-day retention).

• Step 2: Use AI tools like Uber’s free CausalML to estimate variances in outcomes, eliminating underperformers (e.g., channels with >20% higher iCAC).  If you are one of our customers, our full suite of causal inference marketing tools is available through our monthly service.

• Step 3: Monitor for bias (e.g., ensure diverse user segments), validating with a holdout group to confirm causal baseline on S-curve elasticity.

• Expected Outcome: Identify scalable systems with a 10-15% initial lift in iCLV/iCAC ratio.

• Timeline: Expect two weeks of work deploying and at least a week for the analysis the first time.

• Connect to the Source: Thomson Sampling with Empirical Bayes Allocation, or TS-EBA, is an algorithmic approach to minimizing regret.  Randomly sample your channel performance, weighting the samples based on history or your best guess for what channels win in a performance race,  and then adjust your budgets to the channels with higher variance/promise of performance.  Adapt TS-EBA's regret-minimizing approach for marketing, ensuring decisions focus on systems over one-off campaigns. You make decisions within days and abandon “flat” curves without remorse. 

Spoiler alert, this code is just a long way to implement the bullet point above:

import numpy as np
import matplotlib.pyplot as plt

# Step 0: Simulate marketing channels as a multi-armed slot machine
# Each 'arm' represents a digital channel (e.g., Facebook Ads, Google Search) with unknown expected performance (e.g., ROI lifts)
num_arms = 5  # Number of channels
true_means = np.array([0.1, 0.2, 0.3, 0.25, 0.15])  # True performance probabilities (e.g., conversion rates or lifts)
num_rounds = 1000  # Total budget/iterations for testing
initial_budget = num_rounds  # Fixed budget for best-arm identification

# Our best guesses starting performances (also called a prior, we are starting everything at one)
alphas = np.ones(num_arms)
betas = np.ones(num_arms)

# Track cumulative regret (lost opportunity from not choosing the best arm)
best_arm = np.argmax(true_means)
regret = np.zeros(num_rounds)
cumulative_regret = 0

# Track budget allocations and pulls
pulls = np.zeros(num_arms)
rewards = np.zeros(num_arms)

# TS-EBA Implementation
for t in range(num_rounds):
    # Step 1: Exploration via Sampling (TS)
    # Sample from guesses (Bayesian priors with a Beta distribution) for each arm
    samples = np.random.beta(alphas, betas)
    chosen_arm = np.argmax(samples)  # Select arm with highest sample (random exploration based on priors)
    
    # Pull the arm (simulate performance based on the true mean)
    reward = np.random.binomial(1, true_means[chosen_arm])
    
    # Update pulls and rewards
    pulls[chosen_arm] += 1
    rewards[chosen_arm] += reward
    
    # Update history (Beta posteriors, Bayesian update)
    alphas[chosen_arm] += reward
    betas[chosen_arm] += (1 - reward)
    
    # Calculate regret for this round
    regret[t] = true_means[best_arm] - true_means[chosen_arm]
    cumulative_regret += regret[t]
    
    # Step 2: EBA Refinement - Empirically adjust spending
    # After initial pulls (e.g., after 20% of budget or 20% of time, your choice), focus on high-variance arms
    if t > 0.2 * num_rounds:
        # Compute the variances (high-variance = uncertain/promising)
        variances = (rewards / pulls) * (1 - rewards / pulls) / pulls  # determine the distribution of our sample
        variances[np.isnan(variances)] = 1.0  # Handle un-pulled arms
        
        # Adjust measurement (sampling): Weight towards high-variance arms
        samples *= (1 + variances)  # Refinement: Boost uncertain arms for better exploration

# Outcome: Plot cumulative regret to show lower regret over time
plt.plot(np.cumsum(regret))
plt.title('Cumulative Regret in TS-EBA for Marketing Channels')
plt.xlabel('Rounds (Budget Spent)')
plt.ylabel('Cumulative Regret')
plt.show()

# Print final results
print(f"Best arm (channel): {best_arm}")
print(f"Pulls per arm: {pulls}")
print(f"Estimated means: {rewards / pulls}")
print(f"Total regret: {cumulative_regret}")

In this naive example, we reallocated every five rounds (20 days), but you can try a higher frequency and see the results.  This shifts approval from executions to systems, freeing CMOs for strategy.

2. Move to Causality, Not Attribution

Attribution is "digital astrology"—fitting narratives via rules from history, not facts. As Rajeev Nair notes in his 2025 Humans of MarTech interview, you can't make daily operational decisions from an MMM built six months ago alone; experiments are key, but costly. This niche podcast transcript advocates unified frameworks with causal AI for detecting hidden experiments in data.

For iCLV/iCAC, causality reveals true drivers (e.g., how TV influences digital search ROI), using geo tests or quasi-experiments.

From another 2025 arXiv paper, "Combining Stated and Revealed Preferences" by Meango, Henry, and Mourifie, we extract rules for causal bounds in unmatched data—innovative for marketing surveys revealing heterogeneity in preferences. 

Actionable Rule 1: Geo Test for Causal Validation

• Step 1: Select low-risk regions (5-10% of business) as treatment/control for digital channel tests (e.g., AI-targeted vs standard ads on Meta).

• Step 2: Measure iCAC pre/post (cost metrics) and iCLV (retention/value over 90 days), using causal graphs to model dependencies (e.g., email influencing app downloads).

• Step 3: As before, with bias checks (e.g., demographic parity, gender, race), scaling if lifts >15% before the S-curve flattens. The approach identifies difficult variables in highly regulated industries (come on, everyone knows I’m talking about Banking). It allows for ties to ethical or compliance standards that you are driving with your AI strategy.

• Timeline: Expect at least a week to design the experiment and another week to analyze the results

Actionable Rule 2: Stated Preference Bounds for Causal Inference

• Step 1: Survey customers on hypothetical scenarios (e.g., "Would you renew at X price with Y personalization?") to estimate preference heterogeneity.

• Step 2: Combine with revealed data (actual purchases) for causal bounds on iCLV/iCAC effects, using diff-in-diff for incremental impact.

• Step 3: Apply by anonymizing data, testing in small cohorts to confirm S-curve elasticity.

• Expected Outcome: Tighter decisions, reducing iCAC by 10-20% while boosting iCLV.

• Timeline: Expect a week for the analysis

Below, I drew a Directed Acyclic Graph (DAG) instructing our causal AI tool to look for relationships between the data “Facebook Ads Budget” and incremental cost to acquire (iCAC). Demographics are a confounder here (it’s just a random number in this little model).  More spending increases cost, but you must increase spending to achieve the desired outcome, incremental customers (increasing customer lifetime value). Communicating your hypothesis through a DAG is very useful for AIs and fellow researchers!

The first five rows of our data look like this:

Our coefficient for this cost to acquire an incremental customer is -2.1. That means that for every dollar we spend (add to iCAC), we are reducing Customer Lifetime Value by $2.10, after we adjust for the confounder Demographics.  We are on the flat part of the curve! It’s time to stop spending on this channel and ramp up spending elsewhere.

3. Automate Investments, Not Approvals

If your analytics output is dashboards, you're engineering approvals (and more decks) into the system. Meta and Google automate by plowing experiment outcomes back into bidding—experiment first, model second, experiment on what you just modeled, repeat. In martech startups I consult, tools that deliver insights but no action get ignored. Build for automated treatments.

For incremental return on your incremental investment, automate based on causal lifts to scale S-curves dynamically.

Actionable Rule 1: AI Feedback Loop for Automation

• Step 1: Integrate causal AI (e.g., from CausalML, DoWhy, or our client tools) into ad platforms to auto-adjust bids based on real-time iCAC (acquisition cost) and projected iCLV (lifetime value).

• Step 2: Set thresholds for S-curve monitoring (e.g., pause if marginal lift <5%), using quasi-experiments on historical data for validation.

• Step 3: Ensure ethical automation with human overrides for bias (e.g., channel over-reliance), testing in sandbox environments.

• Tie to Source: Nair's unified framework for operational decisions.

• Timeline: Expect a month of work once you start getting signals from your in-market campaigns.

Actionable Rule 2: Adaptive Allocation Automation

• Step 1: Use TS-EBA-inspired algorithms (from the arXiv paper) to auto-allocate budget to "best" digital channels based on variance estimates.

• Step 2: Run continuous diff-in-diff checks on automated shifts, measuring causal iCLV uplift vs iCAC.

• Step 3: Scale ethically by capping at S-curve peaks, reallocating to new experiments.

• Expected Outcome: 15-25% efficiency gains in revenue scaling.

• Timeline: Expect a month to get it integrated on your production promotions.

Here is a quick example of automating Propensity Score Matching (PSM). The approach allows you to look at the members of the test group and use your propensity to purchase models.  You can then pair (match) those people who had the same propensity to buy but were unable to receive the treatment promotion (their email was reported as spam, or it bounced because their inbox was full). You compare the matched pairs on purchasing behavior.  In this case, the Average Treatment Effect for your DAG was 28, a positive number that’s high enough to imply that you are spending on the elastic part of the S Curve.

import numpy as np
import pandas as pd
from sklearn.linear_model import LogisticRegression
from sklearn.neighbors import NearestNeighbors

# Simulate data: 200 samples
np.random.seed(42)
user_behavior = np.random.normal(50, 10, 200)  # Confounder
ad_exposure = (user_behavior > 55).astype(int) + np.random.binomial(1, 0.1, 200)  # Treatment (high-iCAC ads)
iclv = 100 + 30 * ad_exposure + 2 * user_behavior + np.random.normal(0, 10, 200)  # Outcome

data = pd.DataFrame({'Ad_Exposure': ad_exposure, 'User_Behavior': user_behavior, 'iCLV': iclv})

# Fit propensity model
X = data[['User_Behavior']]
y = data['Ad_Exposure']
prop_model = LogisticRegression().fit(X, y)
data['propensity_score'] = prop_model.predict_proba(X)[:, 1]

# Matching: Nearest neighbors
treated = data[data['Ad_Exposure'] == 1]
control = data[data['Ad_Exposure'] == 0]
nn = NearestNeighbors(n_neighbors=1).fit(control[['propensity_score']])
distances, indices = nn.kneighbors(treated[['propensity_score']])

matched_control = control.iloc[indices.flatten()]
matched_data = pd.concat([treated.reset_index(drop=True), matched_control.reset_index(drop=True)])

# Estimate ATE
ate = matched_data[matched_data['Ad_Exposure'] == 1]['iCLV'].mean() - matched_data[matched_data['Ad_Exposure'] == 0]['iCLV'].mean()
print(f"Estimated Causal ATE on iCLV from Ad Exposure: {ate:.2f}")

Conclusion

Investing in signals that are causal yields disproportionate returns, transforming marketing from guesswork to precision. Experiments remain the gold standard for understanding causality, but they're not always feasible or ethical in fast-paced digital channels. Causal inference offers a vital alternative, analyzing observational data to uncover actionable insights on marginal value versus cost, helping you navigate S-curves without the bloat of endless decks. Through the rules and gems shared here, drawn from my Meta experience and network, you can test quickly, scale ethically, and pivot when curves flatten—driving real lifts for your team.
