Simplify's Take

What believers are saying

  • June 2026 case studies show 20% cloud-cost cuts and 40% faster reporting.
  • Crossjoin recovered $750K revenue in six months by restoring telecom service reliability.
  • 2026 expansion and global project hiring signal demand across Europe, LATAM, and North America.

What critics are saying

  • Crossjoin depends on packaged observability services; Splunk, Datadog, and Dynatrace commoditize that layer fast.
  • If 2026 growth stalls, Almada expansion and international hiring become expensive fixed-cost overhangs.
  • A major client concentration shock in telecom or software consulting could crush revenue quickly.

What makes Crossjoin Solutions unique

  • Crossjoin monetizes observability since 2009, combining performance, infrastructure, and development expertise.
  • March 2026 Almada Dojo 2 expansion deepens its Academy and technical specialization.
  • Crossjoin holds 5th place in Great Place to Work Portugal 2026, aiding recruiting.

The 2025 'Best Workplaces for Wellbeing' Award Isn't For Us. It's For Our People.

The 2025 'Best Workplaces for Wellbeing' award isn't for Crossjoin. It's for its people. It is with immense pride and gratitude that Crossjoin share the news: Crossjoin has been officially recognized as a Best Workplace for Wellbeing in 2025 by Great Place to Work(R) Portugal. While Crossjoin is thrilled to receive this honour, I want to be clear about who it truly belongs to. This isn't an award that management wins; it's an award its people give Crossjoin. My role as Head of Fulfillment is to help create an environment where its team can thrive, and this recognition, rooted in their own voices, is the most meaningful measure of its success. What This Award Really Means The Best Workplaces(TM) Wellbeing title goes one step further, attesting to a superior and measurable commitment to employee health and happiness. The recognition is a direct result of: * Sentiment Assessment: This is the average of the 18 specific wellbeing statements already included in the Great Place to Work questionnaire. This metric captures the real experience of its employees, validating whether they feel that the company supports their physical, emotional, financial and social wellbeing. * Practice Assessment: This is an analysis of the wellbeing-promoting practices and policies that its company implements. This demonstrates that wellbeing is not just an intention, but a strategic priority with concrete programmes in place. "Wellbeing" and "fulfillment" can feel like abstract concepts, but at Crossjoin, they are built on concrete pillars that define its culture. 1. Growth as Wellbeing: Crossjoin believe that professional fulfillment comes from challenge and development. Stagnation is the opposite of wellbeing. That's why Crossjoin invest so heavily in continuous learning through its Crossjoin Academy, mentorship programs, and exposure to diverse, high-impact projects. Crossjoin give its people the tools and opportunities to grow, and in return, they deliver excellence. 2. Flexibility and Trust as Wellbeing: Its philosophy isn't about where you work, but how you can do your best work. Crossjoin operate on a foundation of trust and autonomy. This means offering the flexibility its team needs to integrate their professional responsibilities with their personal lives. By empowering its people with this responsibility, Crossjoin foster a mature, respectful environment where everyone is accountable for delivering results. 3. Connection as Wellbeing: Technology connects systems, but people connect people. Despite its focus on complex technical challenges, Crossjoin has never lost sight of the importance of human connection. The "team spirit" and "welcoming atmosphere" its employees highlight are a testament to a culture built on mutual support. From its team-building events to its daily collaborations, Crossjoin foster a community where everyone feels they belong. 4. Impact as Wellbeing: Fulfillment is also about purpose. The work Crossjoin do in Performance, Automation, and Cloud solutions is critical for its clients. Knowing that your expertise is solving a real-world problem and delivering tangible value is a powerful motivator. Crossjoin is a team of problem-solvers, and the pride Crossjoin take in its work is a cornerstone of its collective wellbeing. To every member of the Crossjoin team: thank you. Thank you for your honesty, your commitment, and your trust. You are the architects of this culture. Every project you deliver, every colleague you support, and every challenge you overcome contributes to making this a truly great place to work. This award is a reflection of you. Crossjoin see this recognition not as a final goal, but as a welcome milestone on its ongoing journey. Its commitment is to continue listening, learning, and evolving to ensure that Crossjoin remains a place where talented people feel fulfilled, respected, and empowered to do the best work of their careers. #BestWorkplaces #GPTWcertified #CompanyCulture #Wellbeing #Teamwork #Fulfillment #EmployerBranding #Crossjoin #PortugalTech
