Strongest Group is a B2B pipeline generation agency. They fill their clients' calendars with qualified meetings through dedicated SDR teams and multichannel outbound, and they do it across 15 countries for more than 250 companies.
But running outbound at agency scale comes with a cost problem most platforms don't solve. Charging per workspace means every new client is another bill before any outreach starts, and and every client still needs lead data, infrastructure, and a sending engine to launch.
Strongest Group wasn't looking for another point tool. They needed one stack that could run outbound for every client, hold deliverability at full volume, and not charge them more every time they signed a new account.
“The Forge stack is the reason we can take on a new client and have them sending the same week. For an agency, that speed is everything.”

Strongest Group evaluated their options and chose the Forge stack because it solved the part of agency outbound most tools don't: scaling client count without scaling cost or operational drag.
They now run all 15 clients on one stack. Leadsforge handles the targeted lead lists, Primeforge supplies the rotation-ready Google and Microsoft mailboxes, and Salesforge runs LinkedIn and email outreach for every client from one dashboard.
With Forge, Strongest Group can take on a new client and have them sending the same week, without per-client costs stacking up or deliverability slipping at volume.
The real test of any stack is what happens when you push real volume through it. Here are the results Strongest Group has driven for clients running on the Forge stack:
Here's what Hlib had to say after running 15 clients on the Forge stack: “Growing an agency means taking on more clients without your quality slipping. This is the stack that lets us do both at once.”
With Forge stack, Strongest Group added more clients without adding more people or more tools. The pipeline didn't suffer for it. For most agencies, that's the difference between scaling and stalling.
