Crowd Energy Was Fading
Stirnu Buks, Latvia’s beloved "Roebuck" trail-running series, draws thousands of runners every season. But by early 2025, sign-ups were flatlining. Loyal athletes stopped returning, and revenue hovered around $60,000 a month.
To get back on track, the team partnered with Sharpen-AI to bring in smart automation and hyper-personalisation—and the results were felt almost instantly.
What Was Going Wrong
Email campaigns felt too generic and failed to spark excitement
Core participants weren't re-registering
Community energy that once felt electric had dulled
With 3,000 runners already signed up for 2024 but fewer new faces joining, the team needed a faster, smarter way to re-engage their base and scale growth—without overwhelming staff.
One Week. One WhatsApp Makeover.
Sharpen-AI launched a no-code, AI-powered WhatsApp chatbot in just seven days. It:
Collected each runner’s pace and preferred distance to personalise communication
Sent short, motivational training tips, trail previews, and friendly nudges
Enabled one-tap sign-ups directly within WhatsApp
The Numbers Tell the Story
Registrations rose 17%, from 3,000 to 3,500
Monthly revenue jumped from $60K to $75K
Lapsed athletes returned, and first-timers joined in thanks to targeted messaging
As the Stirnu Buks team put it, “Old and new runners loved seeing tips matched to their own pace and distance. It felt like having a coach in their pocket—and registrations followed.”
The AI Advantage
17% growth in sign-ups in just 30 days
$15,000 increase in revenue
No manual segmentation, all personalised at scale
Fully deployed in one week, no coding required
What’s Next
Up next, Stirnu Buks plans to roll out live race-day updates for spectators, add support for Baltic and Nordic languages, and begin using predictive analytics to open new race tiers early. With AI now quietly running in the background, Latvia’s top trail series is ready to grow faster and run smoother.
