Company Overview

Wind Growth, founded by René, is an agency specializing in lead generation, RevOps, growth strategies, CRM optimization, and AI implementation. Lead generation remains their top requested service amongst clients.

Challenges

As the saying goes, "To be the best, you must face the worst." And Wind Growth had its fair share of struggles:

  1. Need for comprehensive automation: They sought a tool offering robust features and API access to systemize their business.
  1. A snail-paced follow-up routine: Manual follow-up processes were time-consuming and inefficient.
  1. Unruly inbox management: A lack of a streamlined, automated system left them yearning for efficiency.

Solution

Wind Growth knew they needed a game-changer. Smartlead became their perfect solution with its:

  1. Comprehensive tagging system: This offered a helping hand in managing clients in a single workspace.
  1. API responsiveness: Their wishes were Smartlead's commands. New endpoints were added based on Wind Growth's requests.
  1. Custom variable functionality: This let them create a personalized approach for each client, adding that touch of care and attention.

René says, “I'm a big automation guy. Before using Smartlead, I tried different tools. I realized a lot of them lacked the basic features I needed to take my agency to the next level and automate it effectively."

"Using my automation, I've built a system utilizing your white-label feature. When a lead has a more complex question, I tag them, and my client receives an email. They can then automatically sign in to the app and answer the questions themselves." René reveals.

Results

With Smartlead, Wind Growth not only conquered their challenges but also unleashed transformative results:

  1. Lead generation on steroids: For a single client, 42 meetings were secured in just 1.5 months. The client went from having a $800K sales pipeline to a skyrocketing annual potential of $4-5M! 
  1. Conversion Rate Boost: Thanks to faster response times via tagging, conversions saw an upward curve.
“In one campaign, we got a response rate of 8%, which is a lot for branding and design,” René proudly states.
  1. Reply rate renaissance: An impressive 40% positive reply rate out of all replies painted a picture of success.
  1. Reclaimed time: A colossal reduction in time spent on inbox management and follow-ups.

René says, "Smartlead easily saves me about 40 hours per week. I also installed my custom systems for other agencies, and they save hundreds of hours per month with it."

René mentions, adding, "I might save up to 20 to 40 % on operational costs per year."
