Uptrend was a B2B lead generation agency founded by Maverick Lim that sourced deals for M&A firms in the US. The business generated $15k+ in revenue with 3 clients at $2k retainer, but ultimately failed after 10 months due to poor timing (pre-COVID economic boom), weak branding, and inability to build the necessary databases of business owners. The failure taught Maverick critical lessons about domain naming, niche selection, and the importance of proof-of-concept validation.
