What Castopia does
Castopia is an AI advertising platform for businesses. It makes your ads and marketing content, runs your ad campaigns, and reports on how they perform, all from one place.
You connect your own ad accounts: Google Ads, Meta (Facebook and Instagram) and TikTok. Castopia then creates, manages and reports on campaigns in those accounts on your behalf. It builds the campaigns and ads, adjusts budgets, pauses what isn't working, and shows you the results. Your ad platform bills you directly, and you can disconnect an account at any time.
Castopia also writes posts and videos in your brand's voice and publishes them to the social accounts you connect.
How we handle data from your connected accounts, including Google user data, is set out in our Privacy Policy.
