It's 2026. Sales has changed.

Stop pitching.
Start understanding why customers decide.

Your customers have often already searched, compared and consulted AI before they speak to sales. Yet many organisations still work as if the salesperson has all the answers.

We help companies diagnose and improve their commercial processes. With Greg Trinidad's Diagnostic Selling method and technology that supports the process.

First establish. Then understand. Then treat.
Sound familiar?

Lots of conversations. Few decisions.

Your team is busy, but you don't always know what is holding customers back. These responses are familiar, but they don't yet tell you what the real cause is.

Nice story, we'll let you know.
We don't have the budget right now.
We're still looking around.
Just send us a proposal.
We're not doing anything right now.
A different starting point

From sales activity to insight into decisions.

Not working harder, but understanding better where the process gets stuck. That calls for a different order.

Traditional approach

Activity at the centre

  1. Buying reach and leads
  2. Making contact and presenting
  3. Sending a proposal
  4. Following up again and again
  5. Hoping for a decision

Risk: lots of activity without insight into the reasons why customers do not move forward.

Diagnostic Selling

Decision at the centre

  1. Generating targeted demand and supporting orientation
  2. Investigating the situation and the conditions for a decision
  3. Qualifying relevant opportunities
  4. Advising and guiding in a targeted way
  5. Measuring results and improving the process

Goal: base every next step on what has actually been established.

Greg Trinidad's method

Why customers do or do not decide.

Interest is not the same as a decision. Within the Fire Triangle, Diagnostic Selling investigates three conditions: stake, trust and urgency.

A Digital Sales Consultant establishes what is missing and investigates how the organisation can guide customers better.

Stake

Why him. What does this person notice themselves if the problem persists?
02 · OXYGEN

Trust

Why you. Can they carry the risk of choosing you, and of being held accountable for it later?

Urgency

Why now. What happens if they leave this as it is for another year?
What we build

Four connected parts. One commercial organisation.

A Digital Sales Consultant is a commercial adviser, not a software package. We help align the people, processes and technology around your sales organisation.

01 / DIGITAL ADVISER

Henk AI

Answers questions, explores needs and helps visitors towards a suitable next step, within the limits of your knowledge and agreements.

02 / VISIBILITY

SEO & GEO

Content that answers relevant customer questions, with attention to findability in search engines and AI-supported search experiences.

03 / DIAGNOSIS

Qualification & follow-up

Targeted questions, funnels, diary appointments and email follow-up. Diagnostic Selling is central; BANT can be used in addition.

04 / INSIGHT

Process, data & CRM

Touchpoints, opportunities and next steps become visible. Converdis is in development; until then, existing CRM solutions can be used.

Investment & approach

What does it cost to improve your sales organisation?
We only know once we know what is needed.

No two companies have the same commercial challenges. In one organisation the bottleneck lies in the quality of the leads, in another in the sales process, customers' decision-making or the collaboration between marketing and sales.

That is why we do not start with a standard package or a price list. In a first conversation, we explore where your organisation stands and what you want to achieve. If a more extensive diagnosis is needed, we agree in advance what it involves and whether there are costs attached.

Only once it is clear which approach and work are needed do we make a suitable proposal with a clear investment.

Do you work with fixed rates?

No. Our services are tailored to the situation, objectives and needs of your organisation. During a first introduction, without obligation, we investigate which next step makes sense. When an extensive diagnosis or implementation is needed, we make clear agreements in advance about the work and the investment. No paid work is started without prior agreement.

The vision behind the system

What a buyer asks for is rarely what they actually want to buy. That is where sales begins.

Organisations invest in marketing, CRM, campaigns and training. Yet one question often remains unanswered: why does the customer ultimately make a decision, or not?

It was from that question that Greg Trinidad developed Diagnostic Selling. Digital Sales Consultant puts this method into practice by connecting people, processes and technology.
