Revenue from social ads increased by 366%

Castiels was founded in 2023 with the mission of reimagining the classic ballet flat through a modern and feminine lens. Their approach blends timeless design with comfort and quality, focusing on carefully crafted production and thoughtfully selected materials to support women in their everyday lives with elegance and ease.

As a newly launched brand with a strong product and clear identity, we’ve worked alongside Castiels since day one, building their website and shaping their digital presence over the past three years. Through a combination of email marketing automation and paid social ads, we’ve helped them grow awareness, acquire first-time buyers, and foster lasting customer relationships.

“Working with STRAT is an outstanding experience. They become part of your team, deeply engage with the project, and consistently bring new ideas for improvement.”

Social Advertising

Advertising on platforms like Facebook and Instagram offers powerful audience targeting capabilities, which is why so many brands compete for visibility there, driving up both competition and costs. Yet, with the right strategy, creative execution, audience segmentation, and continuous optimization, exceptional growth is still very achievable.

This has been the case for Castiels: over the past two years, we’ve scaled their ad spend by 176%, boosted ROAS by 43,4% and reduced customer acquisition costs by 35%. Altogether, this translated into a remarkable 366,2% year-over-year increase in ad-driven revenue.
