Wind Growth

Wind Growth is your go to Growth Partner when you want your lead generation taken care by experts. We understand that most of the time an agency struggles with lead generation, there’s other factors involved, which is why we’ve developed our GRAALS protocol that takes a holistic approach. GRAALS stands for: Growth Strategies, RevOps, Automation & AI, Lead Generation, Smart Research. The truth is, in 2023 you don’t want to be relying only on one or two acquisition channels. In that sense, cold outreach with Email and LinkedIn is an amplifier to what you already have as a business, and a diversification play. Cold outreach is not only a way of closing more clients, it’s also a fantastic source of traffic that you need to point toward your sales assets to be optimal. According to Salesforce, it takes up to 6-8 marketing touches to generate a viable sales lead. This is exactly why cold outreach has a different chance of success with businesses that have 0 sales assets and businesses that have tons of case studies. Compared to most other lead generation agencies on the market, at Wind Growth, we modeled our approach to take this into consideration when we work with a client. This allows us to see some holes your company might have and work with you to fix those so that cold outreach actually works for you. Here's what's included in term of lead generation: -Fast 1-On-1 Onboarding -Building a database of qualified leads -Crafting the best offer for your campaigns -AI SmartFlow Automation Setup -Weekly Reporting -Weekly 1-On-1 Meeting -DFY Managed Email Campaigns -DFY Managed LinkedIn Campaigns -AI Custom Videos Outreach -Custom Client App -KPI Dashboard -Fast Support Check out our presentation video here: https://www.youtube.com/watch?v=OgCSEQSpf-w
