Compared to Optimizely, which often starts at several thousand dollars per month for similar capabilities, Ninetailed's $300/month Lite tier is significantly more accessible. While more niche than a full CDP like Segment (which also has a free tier but scales quickly), Ninetailed offers a focused personalization solution at a competitive entry point.
