Why Your Ads Aren’t the Problem: Fixing the Real Growth Bottlenecks with Ivan Janku
What actually breaks growth in a business?
It is rarely just the ads.
In this episode of Built to Sell | Built to Buy, Sam Penny sits down with Ivan Janku, founder of Digital Rocket Ads, to unpack what really sits behind profitable growth in 2026. Ivan has helped generate more than $250 million in client revenue, building his agency from a solo freelance operation in Serbia into a global growth business with a reputation for no-nonsense execution.
This conversation goes deep into the hidden leaks most founders never see. Ivan explains why so many businesses blame traffic when the real issue is the website, the customer journey, broken tracking, weak offers, or systems that do not work together. He shares how his team audits businesses, prioritises fixes, and builds what he calls a more cohesive growth engine rather than just running platform-based marketing.
Sam and Ivan also explore what has changed in digital marketing, including Meta’s Andromeda, AI-assisted creative production, attribution challenges in a post-iOS world, and why so many founders are still making decisions from inside the business rather than through the eyes of the buyer. Ivan’s central message is clear: stop guessing, stop hiding behind vanity metrics, and start fixing the leaky bucket.
You will hear real examples from the trenches, including a fashion brand whose growth was being crushed by a cart bug, enterprise clients wasting huge ad budgets with poor reporting, and the dangerous habit of founders relying on agencies without understanding the full system behind performance.
This episode is for business owners, marketers, and operators who want to scale without chaos and build something more valuable, more saleable, and far more robust.
In this episode:
* How Ivan built Digital Rocket Ads from Serbia into a global agency
* Why most businesses have a “leaky bucket” long before ads are the issue
* The biggest blind spots founders have in their customer journey
* Why audits should come before ad spend
* The website and mobile performance mistakes crushing conversions
* What Andromeda changes inside Meta advertising
* Why attribution is harder than ever and what to track instead
* The role of AI in creative, copy, and campaign production
* Why systems beat rock stars when building a scalable agency
* The mindset shifts required as a founder grows from solo operator to leader
Key takeaway
If your growth feels stuck, the answer is probably not “more ads”. It is more likely better systems, better buyer understanding, cleaner tracking, stronger offers, and the discipline to fix what is broken before pouring fuel on it.
