What it is

The Buyer Behavior Brief is a human-led, behavioral science-backed process* that turns existing market signals into a crisp hypothesis about who your buyers are, what they want, and why they will buy (or will not buy).

*The Prometheus Engine with 75+ behavioral science elements (not just demographics).

What you receive

Human guidance, not another prompt.

In the Buyer Behavior Brief, you'll receive human guidance backed by detailed ICP insights and market data to help you get customers buying faster.

Make the next market decision with better evidence

As a B2B founder, being wrong is expensive, but so is not taking any risks.

The Buyer Behavior Brief provides B2B founders with clarity on a high-stakes market decision.

Understand the target personas, their decision-making processes, their biases, their incentives and concerns as well as the market dynamics and competitive landscape that shape the opportunity you’re considering.

Janine Marill Consulting LLC draws from embodied human experience to understand relationships and interaction as well as findings from behavioral science-backed modeling and research to analyze your opportunity and provide structured insight.

At the end of this process, you have:

a documented buyer hypothesis
Specificity on who to prioritize
Context on your buyers’ decision-making process
Recommendations on the offer positioning, pricing band / structure and messaging are likely to resonate
Guidance on next best actions, including whether to pursue the opportunity and if so, what real-world validation activities are likely to yield the highest ROI

Why you can’t rely on AI alone

There's a reason that relying on traditional AI models isn't leading you where you want to go.

What most AI training implicitly assumes

Who it's for

The Buyer Behavior Brief is for B2B founders and operators facing an important market decision with too many plausible directions and not enough confidence about which one deserves the next serious investment.

You have a credible product, service, or market opportunity.

Before doubling down on your investment or making changes in the business, you need to decide which buyer, use case, offer, or go-to-market path to prioritize.

You need to separate signal from noise.

Though you have information from customers, peers, sales conversations, or your own experience, those signals are fragmented, conflicting and incomplete.

You make decisions with judgement and accountability but you desire support from a sharp, experienced human with common sense and a capability to intuitively connect the dots based on research on customer personas and markets.

How it works

How the Buyer Behavior Brief works

When you invest in a Buyer Behavior Brief, the first step in our journey together is gathering and documenting a thorough understanding of your business.

Questionnaire and booking link

You receive a questionnaire and a booking link for our intensive call. The questionnaire must be completed at least 48 business hours before the call.

The intensive call

We view your product demo and dive deep into your hypotheses on and experiences selling to customers, to uncover angles and insights you may not have considered.

In-depth buyer profile creation

Once the existing customer dynamics and hypotheses are established, the research process builds out who your potential buyers actually are.

Synthetic focus groups

Run using proprietary behavioral science models, with additional research performed as necessary to understand what causes buyers to buy.

The compiled report

Findings from the deep discovery and the research empower you to identify and activate ideal customers based on your market position and behavioral science-backed insights.

The debrief call

You receive the Buyer Behavior Brief and participate in a debrief call to discuss the results and have your questions answered.

About Janine

In the trenches with early stage startups for 6+ years.

From validating AI SaaS products through live customer discovery to bringing in high-profile supporters for early stage orgs, I've been in the trenches locating and creating momentum for early stage startups for 6+ years.

In 2025, I worked with Porsche and JB Hunt-backed startups. I produced high-quality leads in the ICP requested and guided the ICP through customer discovery feedback. For JB Hunt, I conducted a deep customer discovery study with live data collection and produced customer discovery insights in a real volume of market data to guide product direction and select the product to focus on (and the product to kill off) for a specific ICP.

Previously, on behalf of an EdTech startup, I secured high-profile (household names, extremely relevant and highly regarded) ideal clients as officially endorsing supporters for a US SBIR grant. Grant reviewers specifically recognized the quality of the supporters I sourced and secured.

I enjoy helping companies see their product in a different light, consider different angles on customer purchasing patterns and speak to ideal customers more clearly. While I incorporate cutting-edge, proprietary technology into my business, I manually review and select from outputs by applying common sense, curiosity, intuition, and evidence.

"I value investing in myself as a brilliant, vibrant, creative, insightful human."
