About

We built the agency we wished existed.

CeyagMark exists because most marketing agencies are built for the wrong thing. Billable hours, big retainers, and reports that look impressive but never reach your bank account. We do the opposite.

The belief that started it

Marketing should be an investment with a return you can measure, not a cost you tolerate and hope works. Yet most businesses are sold marketing as activity. Reach, impressions, engagement. Activity is not growth. Growth is more revenue, kept at a better margin, from customers who come back.

So we stripped the agency down to what actually moves money, which is acquisition, conversion and retention, and rebuilt the engine around AI. The repetitive heavy lifting that used to need a department now runs on agents, supervised by senior strategists. That makes us fast, lean, and honest about price, because we are not billing you for overhead.


What we refuse to do

  • The loud bro marketer aesthetic, with screenshots, hype, and pressure tactics.
  • Vanity reporting that celebrates reach while cost per acquisition quietly climbs.
  • Layers of account managers between you and the people doing the work.
  • Retainers priced to fund the agency headcount rather than your growth.
The founder

Built and run by Shashika Tharinda.

CeyagMark is led by Shashika Tharinda, who has spent 5 years in performance marketing across paid media, conversion and analytics. The work is senior from the first call. You talk to the person who runs your account, not a sales rep who hands you off.

Our engineering partner

When a project outgrows a website, we do not subcontract it to a stranger.

Marketing work runs into engineering limits quickly. A client needs a booking system with capacity rules, a native app, or a data pipeline. Most agencies either say no, or quietly hand the job to a supplier nobody has met.

We work alongside AxionCore, a software engineering company founded by a long-standing business partner of ours. Two companies, not one wearing two names, and we lead with that rather than let you find it out later. What it means in practice is that we plan and deliver as one team, with the same people accountable from the first strategy call through to the software in production.

Nirmal Danansooriya

CEO, Platform Daddy · managed Shashika directly

“I had the pleasure of working with Shashika at Platform Daddy, where he served as a Senior Digital Marketing Specialist on my team. He has a real strength in performance marketing — consistently building data-driven campaigns that delivered strong ROI, with a sharp instinct for optimizing spend across channels to get the most out of every budget. He played a key role in marketing Sri Lanka's biggest agri-food and tech event, and led massive campaigns for large-scale corporate brands, handling that scale with a level of precision and confidence that stood out. He's efficient and gets things done quickly without compromising on quality, and he brought sharp strategic thinking to everything he owned, always trusted to take a project end to end without needing to be micromanaged. Beyond his skills, he's a genuinely kind person and a great collaborator, someone who lifted the people around him and made the team better simply by being part of it. Any organization would be fortunate to have Shashika on their marketing team, particularly for performance-driven growth roles at scale. I recommend him without hesitation.”
