GrowthBiz Media isn't only an appointment setting agency. We have experience across the full sales funnel — generating the prospect, qualifying them, booking the appointment, and in some campaigns, taking over the conversation and closing the customer.
Hi, I'm Nahin Hossain, Founder of GrowthBiz Media. I specialize in outbound lead generation, cold calling, and appointment setting for businesses across the US, Australia, and the UK.
Throughout my career, I've built and managed outbound sales teams, developed sales systems, created qualification frameworks, and personally worked as a closer across solar and battery, heat pumps, pay per call, B2B, and home service campaigns. My focus isn't simply generating leads — it's building repeatable systems that help businesses create predictable revenue growth.
We understand what the prospect wants, what the appointment setter needs, what the closer needs, and what the business owner ultimately cares about — revenue. Our job is to connect those pieces together.
A lead is only as good as the conversation behind it. We'd rather hand you three confirmed, qualified appointments than a hundred cold contacts.
We've managed outbound campaigns across the US, Australia, and the UK — from home service contractors to B2B sales teams.
Trained calling teams of 15 to 30 agents, tight qualification standards, and outbound infrastructure built on ViciDial, GoHighLevel, HubSpot, Salesforce, Phone2.io, and KrispCall.
A transparent, results focused partner — appointments booked, calls transferred, or sales closed, backed by sales scripts, SOPs, and KPIs built for your business.
A short call is the fastest way to find out what a booked pipeline — or a closed sales campaign — could look like for your business.
