01BAYESIAN SALES INTELLIGENCE

Will this customer sign with me?

The meeting is over. But are you really closer to a contract?

The subtle signals behind a customer’s words and reactions are far more than subjective impressions. Although their words and the tone of the conversation remain qualitative, every response becomes meaningful data.

ExaWin+ immediately captures the subtle cues in a customer’s silence, questions and attitude as qualitative signals, performing sophisticated Bayesian Updating.

It transforms a sales process once confined to subjective judgment into mathematically validated win probabilities, establishing a firm basis for the next action. You can now bring sales uncertainty under clear, scientific control.

Why we built ExaWin+
ExaWin+ Decision Console & Ontology AI
Decision Console & Ontology AIEXAWIN+

Capture signals as evidence, update Bayesian probabilities and decide your next strategy.

Help your sales team identify where to concentrate resources and when to walk away decisively, so they can precisely design the next meeting for a stronger chance of winning.

01Did this meeting change our win probability?

02Which deal should we focus our resources on?

03Which signals should we capture and validate in the next meeting?

02WHY EXAWIN+ EXISTS

Only when you can measure your sales process can you truly manage it.

A positive meeting does not necessarily bring you closer to a contract. How do you evaluate a customer’s interest, hesitation or commitment? Representatives and leaders face the same question: “Will this customer sign with us?” ExaWin+ began as a way to provide scientific feedback on that question.

Qualitative signals captured during meetings are transformed into meaningful evidence, and a Bayesian model calculates win probability in real time. As meetings accumulate and new evidence is gathered, the probability is progressively refined. This scientific foundation enables sales teams to clearly decide whether to concentrate resources, conduct further validation or withdraw early.

ExaWin+ goes a step further, beyond calculation alone. Once you identify the signals needed for the next stage, you can proactively design the strategy for your next meeting. By seamlessly connecting signal capture, probability updates, strategic judgment and the next action, it empowers sales teams to take the lead in data-driven decision-making.

03READ THE PROBABILITY

With every meeting, your probability of closing becomes more refined.

Signals confirmed in meetings are the strongest evidence of a customer’s underlying intent and a deal’s progress. ExaWin+ incorporates them into a Bayesian mathematical model, updating win probability as new evidence accumulates. By following probability trends and their supporting evidence, sales teams can assess their current pipeline objectively and put optimal resource allocation into practice.

01Concentrate resources when the win probability is established.
Identify the evidence that drove the win probability, then confidently concentrate your key people and time.
02Withdraw early when the odds of winning are low.
Objectively assess accumulated negative signals and declining win probability to avoid wasting resources and focus on more valuable deals.
03If uncertainty remains, seek the evidence you need.
Trace the sources of uncertainty in the current probability to identify the essential questions you must clarify with the customer in the next meeting.

The actual ExaWin+ engine precisely incorporates complex, multivariate conditions, including sales-stage weights, time between meetings (Decay) and signal reliability, into its calculations.

04DECISION CONSOLE

Take the lead in designing your next sales move, grounded in data.

Which signals should you elicit in the next meeting to move the deal forward? Analyzing the evidence accumulated so far clarifies the key signals you need to capture and helps you develop a strategy to elicit them. ExaWin+ goes beyond evaluating the past, connecting directly to the precise design of your next action.

An example question for designing the next meeting

“To validate the customer’s actual intent to adopt in the next meeting, what should we propose and what response should we elicit?”

  1. 01

    Define the key signals you need to validate

    Analyze the deal to diagnose the evidence behind the current win probability and identify what is missing. Pinpoint the key customer intentions and responses you need to confirm to move to the next stage.

    Current evidence analysis → Signals to validate
  2. 02

    Develop a strategy to elicit the signals

    Design precise questions, proposals and plans to engage key stakeholders so you can validate the target response. ExaWin+’s Decision Console recommends the optimal execution strategy and its supporting evidence.

    Target signals → Meeting strategy design → Execution
  3. 03

    Update Bayesian win probability based on the customer’s response

    Record the signals observed in the meeting. Update probability with the new evidence, then reconsider strategy and resource allocation.

    Observed signal → Probability update → Next strategy

The roles of project analysis, Decision Console and Ontology AI

They help sales teams clearly understand the evidence behind the data and take the lead on the next action. Exa Ontology connects customers, decision-makers, meeting context and observed signals into a unified knowledge system. Drawing on this full context, project analysis, Decision Console and Ontology AI provide sophisticated feedback, clear grounds for judgment and optimized next-action recommendations.

05THE WORKSPACE

To make this ExaWin+ logic work in the field, intuitive interfaces and on-screen controls provide the fullest support throughout the field workflow.

Salespeople must be able to capture meeting signals immediately, interpret data feedback and translate judgment directly into the next action. ExaWin+ simplifies the user experience into an intuitive workflow for the field. On mobile and desktop alike, it fully supports sales representatives and teams in executing the entire process without interruption.

06EXAWIN+ IN YOUR HAND

Customer meetings and team decisions, connected in real time.

Evidence is captured in face-to-face customer meetings, and strategic decisions take shape through team collaboration. ExaWin+ mobile bridges the field and the office. Signals captured immediately after a meeting are instantly translated into Bayesian analysis and shared with the entire team, while the resulting strategy carries directly into the next customer meeting.

07LEARN FROM OUTCOMES

Learning from real sales, evolving toward criteria optimized for your team.

Beyond updating deal win probabilities with evidence from each meeting, the system learns on its own from the final outcomes of completed deals (Won/Lost). Auto-Tuner compares these outcomes against the signal data gathered throughout each deal, recommending optimal adjustments to the probability model and weights for future sales.

Auto—Tuner.

LEARN / REFINE
  1. 01 / Signal Lift

    Signal impact analysis

    Cross-compare signals observed in won and lost deals, using precise mathematics to reassess each signal’s positive or negative impact and discriminative power.

  2. 02 / Refine

    Parameter optimization

    Analyze the relationship between actual outcomes and signals through Grid and MCMC simulations, precisely adjusting signal weights and stage transition criteria to fit your sales environment.

  3. 03 / Cross-validation

    Cross-validation and deployment

    Prevent overfitting through Bayesian deep learning cross-validation, then compare the model’s recommended parameters with existing settings before applying them safely.

An administrator reviews the rationale behind the system’s recommendations and gives final approval on whether to apply them. Before data accumulates, the system starts with a rigorously pre-validated default model. As deal data grows, the scope and accuracy of learning tailored to your organization become increasingly refined.
