About Angelos

I help companies grow with a smart mix of strategy, design, and conversion-focused marketing.

After more than 10 years of experience – including as Chief Marketing Officer at Hard Rock Casino Online Netherlands – I have gone independent under the name Granseal. I work for entrepreneurs, scale-ups, and brands that need clear positioning, strong visual communication, and online results.

My strength lies in combining marketing strategy, branding, and UX design. From websites and funnels to brand story and campaigns: I always think from the end customer's perspective and the bigger picture.

✅ Experienced in B2C & B2B
✅ Available for both strategic and execution roles
✅ Fast-paced, clear communication

Looking for a reliable partner for your brand, website, or marketing approach? I'd love to help.

    CMO
    December 2023 - May 2025 (1 year and 5 months)
    As CMO, I was responsible for setting up and managing the entire marketing organization of Hard Rock Casino Online in the Netherlands. I combined strategy and execution to build a strong brand in a regulated, competitive market.

    Key responsibilities & achievements:

    Developed the go-to-market strategy for the Dutch launch, including positioning, branding, and activation.

    Led a multidisciplinary team (internal & external) for digital marketing, creative, content, and CRM.

    Launched successful campaigns through SEO, social, display, partnerships, and influencers.

    Was ultimately responsible for acquisition and retention strategies, focusing on ROAS and lifetime value.

    Coordinated collaboration with international stakeholders within the Hard Rock organization.

    Ensured compliance with Dutch legislation and advertising code (KOA/VPB) across all communication channels.

    This experience further deepened my strength in brand strategy, performance marketing, and team leadership – with proven results in a demanding market.
