Client

CXLABS ↗
Industry: Customer Experience / Revenue Operations Market: EU (HQ: Poland) Model: B2B Services & Consulting (monday.com implementation partner)

CXLABS is a top monday.com partner agency in Poland, specializing in AI-powered work environments for brand operations. They build intelligent workflows on monday.com, deliver brand technology solutions (portals, approval flows, compliance tools), and coordinate global brand rollouts serving enterprise clients like AGCO, Blackline, and Megamark. 100+ clients, 150+ shipped projects.

Challenge: 3 service lines without market data

CXLABS had built three monday.com-based products for three different verticals. 

The main problem: no empirical data on which segment responds to which offer.

Strategic decisions were based on internal conviction, not external demand. Before committing resources to any service line, the team needed answers to specific questions:

  • Which vertical responds? E-commerce operations, marketing agencies, or FMCG brand management?
  • Which decision-maker engages? CEOs, Heads of Operations, Brand Managers, or Project Managers?
  • Which message resonates? Centralized reporting, approval workflow automation, or compliance risk reduction?

Without this data, every GTM decision was a guess. CXLABS needed a structured way to test all three segments.

What hypotheses we tested?

We defined 6 campaign-level hypotheses across 3 verticals. Each hypothesis combined:

  • Specific ICP
  • Decision - maker persona
  • Taliored value proposition

Segment 1: E-commerce

  • CEOs of Shopify/Shoper stores (50+ employees) need centralized order, fulfillment, and helpdesk data in monday.com to eliminate manual reporting.
  • Heads of Operations and Project Managers in e-commerce respond to operational efficiency messaging.

Segment 2: Marketing

  • Creative agency CEOs (11-50 and 50+ employees) experience an "approval bottleneck" that monday.com + Ziflow solves by centralizing feedback and version control.
  • FMCG Brand Managers face compliance and retail deadline risks that structured approval layers in monday.com address directly.

Segment 3: CRM

  • Mid-market companies need a CRM layer inside monday.com instead of a standalone tool.
Our solution

How we validate PMF in practice?

We ran this engagement as a PMF Validation — Vanderbuild's structured process for testing whether a product has real demand in specific buyer segments before full resource allocation.

01
Outbound + offer workshops
We defined sales hypotheses and offer angles for each vertical together with the CXLABS team. Three distinct value propositions. Six campaign variants.

02
Sending infrastructure setup
12 mailboxes across 4 domains. Warm-up, SPF/DKIM/DMARC configured from scratch. Delivery rate across all campaigns: 97.9–100%.

03
Prospect research and enrichment
Using Clay and BizRaport, we built enriched contact databases targeting CEOs, Heads of Marketing, Brand Managers, and Project Managers in each vertical.

Multichannel campaign execution
Cold email sequences (4-step: first message → A/B tested follow-up → follow-up #2 → break-up) and LinkedIn outreach ran in parallel. Each segment received tailored copy — not recycled templates.

05
Weekly reporting and signal classification
Every reply categorized: interested, objection, wrong person, not now. Weekly reports showed which hypotheses generate signal and which ones to cut.
Signal-based iteration

Insights from the market

The data told a clear story after 3 weeks of live campaigns:

Marketing segment = strongest PMF signal. 

Both creative agencies and FMCG Brand Managers responded with high engagement. The "approval bottleneck" message hit a real pain point. 3 out of 4 qualified opportunities came from this vertical.

E-commerce = weaker signal, needs iteration.

Lower reply rates suggest either messaging mismatch or weaker urgency in this segment. One qualified opportunity came from the CEO Shopify/Shoper campaign, indicating potential with adjusted positioning.

Key takeaway for CXLABS

Double down on Marketing/FMCG. The approval workflow + compliance messaging resonated with Brand Managers at food and consumer goods companies. This is the segment to scale first.

Vanderbuild validated our PMF in 3 weeks. 4 qualified opportunities, a clear winning segment, and data on where not to invest. Exactly what we needed.
