Case Study: Strategic Playbook

We set up a 'Challenger' method of lead generation and direct selling for a B2B SaaS platform, which resulted in a 12x increase in meetings per month. The process included the development of the messaging, lead lists, sales deck, case studies, buying guides and other supporting materials to control the sale. They now have a ~10% deal closure rate on a $60k per year average deal size SaaS product.

Case Study: Enterprise AI

We focused on filling the top of the funnel with an account-based approach to average ~8-12 meetings per week. Earlier in the year, Amazon and Microsoft had entered their space and they hired us to help them shift their focus from large enterprise to SMB.

Case Study: Scaling B2B SaaS

Our biggest milestones were 8 - 9 meetings per week off of a 4% meeting conversion rate (we aim for 3% typically) with potential customers, and closing a $2.4M deal within 9 months, which allowed us to double the client’s average deal size as they refined the product, their customer success processes, and their product/market fit.
