Case Studies
Real results from real campaigns
YouTube subscriber growth in 4 weeks
Launched a new product line to a YouTube audience they didn't have yet.
Micro-Mark was launching Micro-Mark Paint — a new USA-made acrylic paint line created to fill a real market deficit for domestic hobbyist paints. SparkLine's Video Analyzer identified exactly which YouTube creators were producing high-performing paint and miniature content, and surfaced paid amplification opportunities timed to the launch. In four weeks, their subscriber count grew 5x as the right creators reached the right audience at the right moment.
brand sponsorship deals closed in 90 days
Turned a 212K-subscriber channel into a consistent brand deal pipeline.
TrickGMD — a gaming content creator and top-ranked GD player with 212K subscribers — was producing high-quality content but struggling to connect with brands willing to sponsor it. SparkLine identified brand categories aligned with his audience, built a positioning brief around his engagement data and niche authority, and helped him close 2x sponsorship deals across gaming peripherals in 90 days.
