House of Growth is a B2B SaaS AEO agency that works with early-stage start-ups and VC-funded scale-ups in Europe to grow their presence on AI search via ROI-focused owned content, YouTube, and Reddit.
The agency was founded by an ex-SaaS founder who built and exited multiple SaaS companies before starting HoG to help other SaaS brands scale on AI search, including Jamie AI, SmartSuite, and Warmly.
Our agency begins work by researching the topics buyers look for when they are ready to evaluate or purchase a solution.
Using our Revenue Focused SEO approach, we’ll help you uncover the bottom-of-funnel topics that match real buying intent.
After defining these topics, our team selects traditional SEO keywords that match how both humans and LLMs search for products in a specific category.
We then work on creating human-led owned content that is strong enough to rank for the target SEO keywords and clear enough for LLMs to understand and recite your product’s positioning.
Here’s what I believe makes House of Growth a better AEO agency than others in the EU market:

If I were selecting an AEO agency in Europe, I would evaluate partners in this order:
Most AEO agencies in Europe provide a mix of strategic, technical and content services to help brands appear as accurate answers in AI search.
These include:
Hiring an AEO agency in Europe typically falls into these tiers:
What I’ve seen drive price is the scope of work, including technical SEO, structured data, content systems, interview-led content, digital PR and measurement.
➡️ Team seniority also affects cost since founder-led and specialist teams charge more but usually deliver faster impact.
Lastly, the volume of content, platform complexity and the number of markets you target also influence total investment.
As someone who has founded and grown 2 SaaS businesses myself, I know how hard it was in the beginning to gain traction, especially with a new growth channel.
This is why I’m willing to support European SaaS start-ups and scale-ups by helping them create their AEO strategy.
