01 /The goal

Launching a new feature in a crowded market demands speed and precision

La Growth Machine had built a powerful new voice outreach feature for its multichannel sales automation platform. It was a genuine differentiator. B2B teams could add personalized voice messages to their LinkedIn, email and outbound sequences.

But shipping the feature was only half the battle. The real challenge was to get it in front of GTM decision-makers fast. Adoption had to come immediately, before competitors could respond.

They needed a partner who could move at startup speed, targeting only the people who buy and implement sales tools, and generate real pipeline from the launch.

We needed to make GTM leaders understand that voice outreach is the next frontier in multichannel sales, and La Growth Machine is the platform that delivers it.

02 /The execution

A 10-day blitz targeting GTM decision-makers

Growth Cab designed and ran a rapid-fire launch campaign. It put La Growth Machine’s voice outreach feature directly in front of revenue leaders. The strategy centered on three pillars.

Step 01

  1. LinkedIn as the distribution engine

    In a 10-day window, the message was distributed through organic LinkedIn content and targeted outbound sequences.

    OutputThe launch message reached the right profiles both organically and directly.
Step 02

  1. Targeting only GTM decision-makers

    Every touchpoint was designed for one audience: the people who choose and implement sales automation tools. That meant revenue leaders, sales directors and growth operators.
