We build the pipeline, you close the deals.
ColdComplex is a go-to-market partner, not a classic lead agency. We run cold outbound and LinkedIn growth on top of the GTM engineering that makes them work, and we run it all as one engine. Based in Amsterdam, working with founders and revenue teams across Europe.
Why we exist
Most outbound fails for the same two reasons: the targeting is lazy and the systems are a mess. Lists go stale, domains get burned, replies fall through the cracks, and nobody can say what actually drove a meeting.
We started ColdComplex to fix both at once. We set up the sending infrastructure properly, build and score the account list with our own stack, write outreach that sounds like a person, and wire the whole thing into your CRM so every reply is tracked. Then we optimise it week over week until the pipeline is real.
How we work
Measured on pipeline, not activity
We report on qualified pipeline added, not emails sent. The number that matters is the one that shows up in your CRM.
AI driven, human curated
Software does the volume and the enrichment. People write the angle, read the replies and make the calls. Neither alone is enough.
Your systems, yours to keep
Every domain, list, sequence and dashboard we build is documented and handed over. No lock in, no black box.
Right account, right person, right moment
We reach out when the timing is real: funding, hiring, a new leader, an intent signal. Relevance beats volume.

Every engagement starts as a four month pilot. We build, launch, scale, then decide together what comes next.
