Personalised cold outbound from our own warmed domains, plus inbound flows when you want them. Replies land qualified in your CRM.
Not just another lead agency
Fill your pipeline
with qualified leads.
We're not marketers guessing at sales. We spent years in the field ourselves: cold calling, emailing, booking meetings, closing deals, even running customer success. So we know what a real deal looks like and what a qualified lead actually is. We run everything up to the reply. From there, it's over to you to close.
The ColdComplex method lands you in the inbox of almost anyone you want to reach: senior decision-makers from scale-ups to the Fortune 500, at companies like Heineken, KPMG, ASML, Booking.com, KLM and ING.

01Services
Grow the top line. Trim the bottom line.
Everything it takes to keep your pipeline full and your revenue growing. Automation runs the repetitive, time-consuming work, so you grow the top line, cut cost on the bottom line, and your team spends its time where it counts: closing.
LinkedIn growth
Profile, content, outreach and targeted ads in one weekly rhythm, so the right people see you and your network fills with real buyers.
Your sales systems
The CRM, dashboards and automation that run your sales on autopilot, built and handed to your team. We take the boring, time-consuming work off their plate so they can just sell.
02How it works
The ColdComplex method.
No spray and pray. A clear system we run the same way every time and sharpen every week, turning a cold market into pipeline you own.
03Why ColdComplex
Pipeline that compounds, not one‑off spray-and-pray.
A team that has actually sold
Most cold outbound is run by marketers and tool operators who have never carried a quota or closed a deal. We have. 15+ years of real B2B sales and business development sit behind every campaign, so the angle, the buyer and the message come from experience, not guesswork.
Always on the latest and greatest
New tools drop every week and we test them all, so we know what actually works and what is just noise. Your outreach stays on the front line, running what performs today, not last year's stack. And yes, that includes AI ;-). We only care whether it moves the needle, not whether it is the buzzword of the month.
Dedicated email infrastructure
If your email lands in spam, nothing works. We run dedicated sending infrastructure on warmed look-alike domains, with placement watched daily. You reach the inbox; your main domain stays clean and protected.
Live in two to three weeks
We move fast. Domains warmed, plan ready, first campaign out in weeks and meetings landing early, with real insight from day one. No three-month ramp. When the timing is right, we are already running.
04Signals
We reach out when the timing is right.
We watch for the moments that mean a company is ready to buy, a new role, a funding round, a hiring spree, and reach out right then. Not a random blast to everyone.

05Who it is for
Is ColdComplex a fit for you?
We create the leads. You close the deals. So we fit B2B teams with someone ready to follow up, a market we can name, and a real number to hit. If that sounds like you, it probably is.
Founder-led teams
Your time is your scarcest resource, and selling devours it. We run outbound for you, so you stay on the deals only you can close while pipeline keeps coming in.
Teams with sales capacity
You have people to follow up: a VP, AEs, SDRs, or a founder still in deals. We hand them a steady flow of qualified leads. They book and close.
B2B with a nameable market
If you can name your buyers, founders, HR, revenue, IT, at companies you can list, we can reach them. The clearer the target, the harder we hit.
Startup to enterprise
From your first pipeline to the C-suite at the largest firms. Startup or enterprise, we target the right people. The logo size is not the barrier, relevance is.
06Case studies and testimonials

20+ engagements from startup to enterprise, with €20M+ in pipeline behind them. Every number real and referable.
In their words
Nobody could get us past the filters in our category until these guys did. $1.1M in pipeline.
110 meetings and around $520K in ARR pipeline, and they reached the actual decision-makers, not front desks.
Seven retainers in 90 days, and I own the system instead of renting leads.
I'd written off cold outbound, and now my sales team is busy with pre-qualified appointments.
Every number here is real and referable. We'll put you in touch with the client on request.

Handover + playbook
We migrate every account and document a full playbook, then train your team. You run it in-house. Handover fee on request.
- Lighter
Advisory

How we work, and what to expect.
The first four weeks are build weeks: domains, warmup, targeting and copy. First replies usually land in week three to five, and volume grows from there.
Yes, for targeted, relevant B2B outreach with a clear opt-out. We use verified business data and clean unsubscribe flows.
No. We use separate look-alike sending domains, warmed up carefully. Your main domain and reputation are never at risk.
Half a day for the kick-off session and input on your audience. CRM access is optional, depending on the scope and what you want. We build and manage the rest.
Scope sets the price: your sending volume, how many channels you run, and how much CRM and multi-threading it takes. It runs from €3,000 per month and scales from there, usually as a four-month pilot. That is a fraction of the pipeline it builds, and you get a fixed number after a short scoping call. No hourly billing.
Nothing automatic, and no lock-in. At month four we review the pipeline added together and decide the path: scale it up, keep it steady, hand it to your team with the full playbook, or stop. You own every domain, list and system from the pilot either way. Most teams continue, because by then the pipeline speaks for itself.
Go-to-market, or GTM, is simply how a company sells: who you target, the channels you reach them through, the message, and the systems that tie it together. When we say we run your GTM, we mean we build and operate everything that sells for you, not just send a few emails.
Revenue operations, or RevOps, is the plumbing behind sales and marketing: the CRM, the data, the routing and the reporting. It makes sure every lead is tracked, every reply lands in the right place, and you can see what is working. We set this up so your pipeline is measurable, not a black box.
Your ideal customer profile, or ICP, is a clear description of the companies and people most likely to buy: their industry, size, role and the signals that show they are ready. We build the target list from your ICP, so outreach goes to the right accounts, not to everyone.
Inbound is when buyers come to you, through your website, content or ads. Outbound is when you reach out first, to the specific accounts you want. We run outbound, cold email and LinkedIn, so you are not waiting for the right buyer to find you.
Deliverability is whether your emails actually reach the inbox instead of the spam folder. It depends on warmed domains, clean lists and sensible sending habits. We manage all of it, on separate look-alike domains, so your main domain and reputation stay safe.
Yes. We work just as well with a tight list of named accounts as with a broad market. If you have fifty dream companies, we map the right people inside each one and run a precise, high-touch campaign. Small and specific is often where outbound performs best.
Yes. A small or niche market is an advantage, not a limit. We map and track every account and every persona in your space, so we can run a hyper-personalised approach to each one, with research and messaging built for that exact buyer. The narrower the focus, the sharper the outreach.
