Case Study: The Kingdom converts 100% of revenue to ongoing retainers and drives 1000% website traffic growth with HubSpot

Australian Agency Partner Converts 100% of Revenue into Retainers Using HubSpot

The Kingdom is an Adelaide-based agency that reinvented itself from a traditional advertising shop into an inbound marketing specialist after struggling to stand out in a crowded market and proving ROI from cold outreach. Frustrated with low conversion from cold calling, Managing Director Adam Steinhardt joined the HubSpot Agency Partner Program in 2015 to differentiate the business and build a predictable lead-generation engine.

Using HubSpot’s all‑in‑one platform and inbound methodology, The Kingdom optimized its website and SEO, quadrupled visits in six months (reporting up to 1,000% traffic growth), achieved a 20% lead-to-client conversion rate, and converted 100% of revenue to ongoing retainers. The agency doubled its team, expanded internationally, earned Platinum Partner status (HubSpot International Partner of the Year 2015) and helped clients—like Brauer—grow databases 325% and increase retainers.
