Client

AI Hero ↗
Industry: Tech & Consulting Market: Poland Model: B2B Enterprise (>200)

AI Hero implements systemic AI solutions like Copilot, Gemini, and ChatGPT, while designing security policies and training employees. Focused on pragmatism, they aim to free up one billion man-hours in Poland by 2030, collaborating with market leaders such as MediaMarkt and Polsat.

Challenge 

AI Hero, working with market leaders such as MediaMarkt and Polsat, faced the challenge of scaling outbound sales. The main business obstacle wasn't a lack of interest in AI (which is actually a trend), but rather precisely reaching the person who, within a large organization (over 200 people), was truly experiencing a lack of technological competence.

Instead of a general message, "We're doing AI training," we had to identify specific pain points for different departments. IT was overwhelmed with questions, HR lacked the training expertise, and Sales wasted time on administration. The challenge was to break through the noise and hype surrounding AI with a pragmatic business proposition.

What is Cold Email Outreach?

This is a strategy of direct contact with the ideal customer (ICP), which, unlike mass mailing, is based on hyper-personalization and relationship building, rather than aggressive selling.

Questions asked

Before we sent the first message, the team asked ourselves key diagnostic questions that defined the campaign:

  • Who is the real "owner" of the problem?Should the decision on AI implementation be made by the IT department, which manages the technology, or by HR, which manages employee competencies?
  • How to break the barrier of silence?Is the lack of response due to a lack of interest or the fact that the topic of AI is "nobody's business" in the company?
  • Is industry personalization enough?Do we need to go deeper, to the level of the daily duties of a specific position (Persona)?

Our Hypotheses

Instead of guessing, we decided to verify 3 hypotheses:

Hypothesis 1

Directing communication to HR with the proposal to "remove the training burden" will yield a higher conversion rate than technical conversations with the IT department.

Hypothesis 2 

Using a "Break-up email" (a message with a deduction of the reason for the lack of response) in the last step of the sequence will significantly increase the Response Rate, forcing the recipient to make a declaration.

Hypothesis 3

Segmenting the message for specific departmental issues (e.g., reporting for Sales vs. IT helpdesk) will build more trust than general "AI benefits."

Solution 

The campaign was designed as a precise process of data engineering and sales psychology.

Solution 1 - Technology

The operational foundation was a technology stack enabling deep personalization:

Our Tech Stack

The engine behind our outreach: a blend of industry-leading automation and custom internal systems.

Clay

Company sourcing, deep data enrichment, and advanced prospect segmentation for precision targeting.

OpenAI API

Automated qualification of companies and decision-makers, paired with AI-driven content tailoring.

Instantly

Campaign execution and comprehensive deliverability management to ensure consistent inbox placement.

Custom Scripting

Our proprietary system for handling complex Polish grammar (inflections and gender forms), manually verified to maintain a perfect, natural human touch.

Solution 2 - Segmentation and Content

We divided the database into 4 hermetic groups (HR, IT, General Management, Sales), creating unique scenarios for each of them:

Target Segments
HR Director
PERSONNEL & L&D
IT Manager
INFRASTRUCTURE
Sales Director
REVENUE OPS
Subject: Solving the AI skills gap in your HR calendar
Hello, I noticed that scaling AI competencies often falls on HR, yet finding internal experts to lead these sessions is a challenge.

We provide a turnkey solution: our experts take over your training calendar, relieving your department and ensuring your team stays ahead of the curve.
Subject: Reducing basic AI support tickets for your team
Hi, your technical staff is likely overloaded with basic "How do I use ChatGPT?" questions from non-technical departments.

We take this burden off IT. We educate employees on the fundamentals so your team can focus on high-level implementations and infrastructure, not basic troubleshooting.
Subject: Turning admin hours into selling hours
Hi, is your team spending more time on reports and drafting offers than on actual sales calls?

We automate these tedious manual tasks, freeing up your reps to focus on what they do best: closing deals and driving revenue.
Strategic Hook: HR

Problem: Lack of internal competence to lead AI training.

The Angle: We act as an external "expert-on-demand" that saves HR's time and fills their training quotas.

Solution 3 -Sequence Tactics 

The sequence consisted of three steps. The key element was the final email (step 3), in which we asked for a reason for the lack of contact:

  1. Competences are already at a good level.
  2. The training has already been completed.
  3. There is simply not enough time.

Business Conclusions 

The campaign provided key information about the current state of the AI ​​implementation market in Poland:

  • HR is the gateway to implementation:In large organizations (>200 employees), HR departments are most likely to respond to AI training offers. IT departments, while competent in their field, often treat such inquiries as just another task and are less likely to respond.
  • The Psychology of "Negative Choice":The most effective element of the sequence was asking for a reason for silence. People were more likely to correct a false assumption ("no, we don't have training yet, I just haven't had time") than to respond to an offer of a meeting.

Financial context: Mentions about the possibility of co-financing training act as a strong catalyst for response

"

The entire process of working with Vanderbuild was thorough and professional - from detailed segmentation, through custom messaging per segment and iterating on sales angles, which resulted in a dedicated campaign focused on the geographic accessibility of our ICP.
