TREND BOSS VS SANDCASTLES
TrendBoss vs Sandcastles: an honest 2026 comparison
A direct comparison of TrendBoss and Sandcastles across social networks, outlier discovery, evidence, short-form video research, creative workflows and pricing.
THE SHORT ANSWER
TrendBoss and Sandcastles both use social performance to inform original content, but they solve different jobs. Sandcastles is a specialist for viral short-form video discovery and scripts across Instagram, TikTok and YouTube Shorts. TrendBoss is a broader private research system spanning six networks, including Facebook, LinkedIn and X.
THE SPECIFIC PROBLEM
Both find outliers, but the content system is different
Sandcastles starts from a large discovery database and is optimised for moving viral videos into hooks, transcripts, analysis and short-form scripts.
TrendBoss starts from the accounts and posts you deliberately capture. It keeps the original source, creator-relative lift, missing evidence and platform draft in one private workspace.
