I've tried to build this in the past with Looria.com, where we aggreagted and summarized reviews from the most trusted sources, e.g. Reddit: https://www.looria.com/reddit https://www.looria.com/reddit Couple of challenges: - Astroturfing is everywhere - The data sources, especially social media, become more protective with their data - Monetizing this is super hard. As an aggregator, you're always just the intermediate. Vetted.ai is working on something similar and they raised $14M in 2022. They are likely faceing similar challenges.
