How to scale outbound from 0 to £1M ARR.

I built the outbound motion that took Haku from zero to its first meaningful ARR. Here is the exact sequence — what to do first, what to skip entirely, and the order in which it has to happen. Most of the advice you will read on this topic is written by people who have never done it. This is not that.

Before founding Haku I spent years as a sales rep. Top of the leaderboard at a Series A HRTech company. I knew how to sell. What I did not know was how to build a sales motion from scratch — how to go from zero conversations to a predictable pipeline when there is no brand, no case studies, no inbound, and no team.

The advice I got from investors and advisors was mostly useless. "Find your ICP." "Get product-market fit first." "Hire a great VP of Sales." None of it told me what to do on Monday morning when I needed to book my first ten meetings from cold.

This post is what I learned by doing it. It is not a framework. It is a sequence — and the sequence matters enormously. Do these things in the wrong order and you waste six months. Do them in the right order and you build something that compounds.

Phase 0: Do it yourself first — before hiring anyone

The most expensive mistake a founder makes in early outbound is hiring an SDR before they have proven the motion works when they run it themselves. An SDR cannot fix a broken ICP. They cannot fix a message that does not resonate. They cannot fix a product that does not solve a clear enough problem. If you hand them a broken system, they will run it at scale and produce nothing — while you spend six months wondering whether outbound works for your business.

Run the outbound motion yourself for the first three to six months. Not because you are the cheapest resource — you are not. But because you are the only person who can learn fast enough to know what to fix. Every reply you get tells you something about who your real buyer is. Every non-reply tells you something about your positioning. Every conversation that does not close tells you something about your product. An SDR generates the same data without the authority to act on it.

“Hire your first SDR only after you have personally closed five deals through outbound and can write down in one paragraph: who I target, what signal triggered my outreach, what I said, and why they bought. If you cannot write that paragraph, you are not ready to hire.”

Phase 1: Close your first ten customers — manually, slowly, deliberately

The goal of phase one is not revenue. It is learning. You are trying to discover who your real ICP is — not who you think it is, but who actually buys, who actually gets value, and who actually refers you. The answer to those three questions is almost never the same as your initial hypothesis.

At this stage, do not automate anything. Write every email personally. Get on every call you can. Take notes obsessively. The data you collect in the first ten deals is more valuable than any tool, any database, or any AI model you will ever buy — because it is the ground truth that everything else gets built on.

Specifically, after each closed deal, answer these questions: What was the trigger that made them open my email? What was the specific pain they described on the first call? What would have made them not buy? What did they say to colleagues when they recommended us? The answers to these questions are your ICP, your signal model, your message, and your case study — all in one.

The pattern you are looking for

Three or four of your first ten customers will look remarkably similar — same industry, same company stage, same trigger, same language when describing the problem. That cluster is your real ICP. The other six or seven are noise. Most founders try to serve all ten equally and end up with a product and a message that resonates with none of them deeply. Double down on the cluster.

Phase 2: Build the infrastructure — before scaling the volume

Once you have closed ten deals manually and can describe a repeatable pattern, the instinct is to start sending more emails. Resist it. The infrastructure needs to be right before the volume goes up, because a bad infrastructure at low volume is annoying. A bad infrastructure at high volume is catastrophic — it burns your sender domain, stales your list, and destroys your reputation with exactly the people you are trying to reach.

Step 1
Set up dedicated sending domains
Never send cold email from your primary domain. Buy two or three sending variants — gethakulabs.ai, tryhaku.ai — forward them to your main site, and configure SPF, DKIM, and DMARC on all of them. This takes two hours and protects your primary domain permanently.
Step 2
Warm every mailbox for 21 days before sending
A cold mailbox sending 50 emails on day one looks like spam. Every new mailbox needs 21 days of warmup — automated engagement that builds sender reputation before your first campaign launches. Use Instantly or Salesforge. Never skip this step regardless of how urgent the pipeline pressure is.
Step 3
Build a signal monitoring system
Your first ten manual deals taught you what trigger preceded each purchase. Now automate the detection of that trigger. LinkedIn job postings. Funding announcements. Leadership hires. Whatever the signal was — set up alerts so you know when the next account hits the same condition. This is what Haku is built to do, but at early stage you can do a manual version with Google Alerts and LinkedIn notifications.
Step 4
Validate your contact data before sequencing
Every contact that enters a sequence should have its email verified against live SMTP checks within the last 30 days. A 3% bounce rate is the ceiling. Above that and you are damaging your sending infrastructure faster than you are building pipeline. At early stage, run every list through a verification tool before loading into your sequencer.

Phase 3: The maths — working backwards from £1M ARR

Most founders approach outbound as a volume question: how many emails do I need to send? The right question is a maths question: given my ACV, my conversion rates, and my timeline, how many qualified conversations do I need to generate £1M ARR? Working backwards from that number tells you exactly what you need to build.

Example: £1M ARR at £20,000 ACV
Customers needed for £1M ARR50
Close rate from qualified demo30%
Demos needed167
Meeting-to-demo conversion60%
Meetings needed278
Cold email reply-to-meeting rate25%
Replies needed1,112
Reply rate (signal-triggered outreach)8%
Targeted emails needed — over 18 months~14,000

14,000 targeted emails over 18 months is fewer than 800 per month — roughly 40 per working day. That is not a volume problem. That is a precision problem. The question is not how to send more emails. It is how to ensure every one of those 14,000 lands in front of the right person at the right moment. At 8% reply rate from signal-triggered, precisely targeted outreach, the maths works. At 2% reply rate from a generic database export, you need five times the volume — and you will burn your domain and your reputation trying to get there.

Phase 4: Scale the motion — not the headcount

Most founders think scaling outbound means hiring more SDRs. In reality, scaling outbound at early stage means automating the parts that do not require human judgment — so the human doing the outbound (whether that is you or one SDR) spends their entire day on the part that does.

The human judgment parts are: writing the first email for each signal type, handling replies, running discovery calls, and closing deals. Everything before the first email — identifying the account, finding the signal, sourcing and validating the contact, building the brief — should be automated before you hire anyone. If it is not, you are hiring a person to do research rather than a person to sell.

The benchmark for when to hire your first SDR: you as founder are spending more than two hours per day on conversations that you cannot close because there are too many of them, and you can hand a new rep a documented playbook with a clear ICP, a signal model, a message framework, and a list of ten example conversations that resulted in closed deals. Anything before that moment, an SDR will flounder — not because they are bad, but because the system is not built yet and they have no way to learn what works.

What changes at £500K ARR

At £500K ARR the motion is proven. You know your ICP. You know your signals. You have a message that converts. You have closed enough deals to have real case studies. This is the moment to hire — not before.

Your first SDR hire should be someone who can run the exact playbook you have built, not someone who will build their own. Give them the 10 example conversations. Give them the ICP doc. Give them the signal model. Give them the message framework. Onboard them through your deals, not through their own from scratch.

At this point, the thing that scales the most dramatically is the intelligence layer — the research, enrichment, and signal monitoring that determines who is on the list each week. A rep freed from four hours of daily research produces meaningfully more conversations. That is where the leverage sits, and that is where the investment compounds fastest.

From £500K to £1M is simpler than from zero to £500K. The hard work is the first half. The second half is execution — running a proven system with more resource behind it. Do not let the relative ease of the second half convince you that you skipped any steps in the first.
