01 The challenge

Barter, an Amsterdam-based influencer marketing startup, struggled to scale its client base efficiently.

They relied on social advertising and affiliate platforms — costly, with limited control. Barter needed to reach a high volume of businesses, explain their barter-deals concept, and drive platform trials.

02 What we built

We built a fully automated outbound engine on Clay with AI-powered cold email, letting Barter connect with small and mid-sized businesses at scale — sharing their story and driving interest without the cost of traditional advertising.

01

Clay-powered research

Clay workflows pulled from 40+ data sources, so every account was fully researched before a single word was written — no scraped lists.

02

AI-personalised cold email

1:1 copy referencing real, specific business details — recent posts, growth signals, news — so every message felt written by hand, not mail-merged.

03

Dedicated infrastructure

Separate sending domains and warmed mailboxes kept the primary domain safe and deliverability high while volume scaled.

04

AI inbox that books the call

Replies, objections and scheduling handled around the clock, with confirmed meetings synced straight to the calendar.

03 Results

Within four months we booked over 1,000 sales meetings for Barter, resulting in 350 platform trials — streamlining client acquisition and helping them scale quickly and effectively.
