The outbound engine you own

Your outbound engine.
Built, handed over, run in-house.

We build the full engine inside your own stack, then hand you the keys. Launch by talking to it, approve from a dashboard, and replies land in your inbox and CRM. No more 6-12 months learning Clay, no more betting on a random agency, and no more £100,000+ a year on SDR or RevOps hires.

Real-time replies, meetings booked and what's working, for you and your team

How it compares

Three ways to do
the same job.

Clay is a genuinely good tool, and we are not going to pretend otherwise. This is simply where each way of working actually fits.

Who owns it at the endA folder of spreadsheetsClay does, and you keep payingYou do, outright
Doing it by hand

Cheap to start and familiar. It falls apart past a few hundred leads, and nothing you send is really personal.

Clay

Powerful and flexible, and the standard for a reason. But you have to become an expert in it first, and most people spend months and a lot of credits finding that out.

Prospectology® Engine

Tell it what you want in your own words, have a campaign out the same day, and own the whole thing at the end. Built to send fewer, better messages rather than more of them.

Why now

Gone are the days of piecing together the tools, the playbooks and the automations yourself. Spin up a campaign in hours, not the days or weeks an agency or a new hire needs. Soon two-person teams will run all of their B2B outbound off agents and terminals. AI is here to stay. Don't get left behind.

Live signals

The buying signals your engine watches for.

Outbound wins on timing. These are the kinds of live triggers we wire your engine to act on, the moment a company enters buying mode. Proprietary pipelines, not scraped lists.

The maths

What the old way costs.
Every year.

Tick what you're paying for today, then see how a one-off engine you own compares.

The old way — tick what you're paying for
And that's before churn, hiring and firing, and weeks of waiting on someone else's campaigns.
Your bill, every year
£200,000
and you still don't own the system
vs
One payment, and the engine is yours
A fraction of a single year of the old way. No salaries, no retainers, no churn, no waiting on anyone.

The offer

One engine.
Three ways in.

Start with a free pilot. After that it comes down to one question, and it is the first thing we will ask you: who operates the engine, your team or ours?

01
Start here

The Pilot

40 days on your real market, free. We build a full engine, you keep every reply, and decide at the end whether to own it. No cost, no obligation.

02
Own it

The Engine

Built inside your stack, your keys, your domains. Runbooks, skills and playbooks handed over, your team trained to drive it. You own the asset outright.

03
We run it

Done-for-you

Same engine, our hands on the wheel. For teams who want the pipeline without operating the machine themselves.

What the pilot actually includes
40
day pilot
6,000
personas
2
campaigns
£0
professional fee

Days 1 to 14 are deliverability setup and campaign mapping, with no sending, which protects your domains. Days 15 to 40 are live outreach, ramped. We take a maximum of three pilots a month because each one is a full build.

What we promise
  • A working engine, built and live
  • Campaigns running on your real market
  • Copy your team could not write alone
  • An operator inside your business, trained
What we never promise

A number of meetings.

Anyone who does is guessing at your market with your money.

Questions

The things you are
actually wondering.

How is this different from an agency we have already tried?

An agency keeps the system. When they leave, the pipeline leaves with them. We build the engine inside your own stack, on your domains and your tooling, then hand over the configurations, playbooks, documentation and the training to run it. If we walked away, the engine keeps working.

Do you guarantee a number of meetings?

No, and we will not. The number of meetings depends on your market, your offer and your own sales process, none of which we control. What we commit to is a working engine, live campaigns on your real market, and a human reviewing every message. Anyone guaranteeing a meeting count is guessing at your market with your money.

Who approves the copy before anything sends?

You do. Nothing sends cold. Every message is scored and bucketed, then a person reviews it. During an engagement you review and approve the initial messaging before we go live, and you keep that visibility throughout.

What actually happens in the 40-day pilot?

Days 1 to 14 are deliverability setup and campaign mapping. We procure and configure mailboxes and domains, finalise the ICP and messaging, integrate the tooling and build the campaigns. Nothing sends in this window, which is what protects your long-term deliverability. Days 15 to 40 are live outreach, with volume ramped rather than opened at full capacity. We review reply and deliverability performance with you around day 35 to 40.

Do we own the data, the domains and the mailboxes?

Yes. The sending infrastructure and prospect data are yours and you keep them whatever you decide at the end of the pilot. Our frameworks and methodology stay ours during a pilot or a done-for-you term. If you commission a full engine build, you get a perpetual licence to use the engine, configurations and documentation inside your own business.

Do you cold call?

The engine does not. It works over email and LinkedIn, and that is deliberate, because those are the channels it can personalise properly and run at volume without burning your reputation.

Cold calling is available on request as a separate service alongside it. Some teams want it, and it can work well once the engine has already warmed a name up. Ask on the call and we will tell you honestly whether we think it is worth it for your market.

How do you handle our data, and will this pass a compliance review?

We work to UK GDPR, the Data Protection Act 2018 and PECR. Prospect data is business contact data from business data providers and public sources, never consumer lists, held on a legitimate-interest basis with a suppression list for anyone who asks us to stop. Campaign data lives in your own stack once the engine is handed over. We are happy to walk your compliance or security team through the tooling and the data flow before you commit.

Can you just run it for us instead?

Yes. That is the done-for-you route, and plenty of teams prefer it. Same engine, our hands on the wheel, a set number of new campaigns each month. You can switch to owning the engine later, and what you have already paid comes off the build.

What does it cost?

The pilot carries no professional fee at all. Beyond that it depends which route you take, whether we run it or you own it, and we will give you exact figures on the call rather than a number on a page that does not fit your situation. You fund your own sending infrastructure throughout, because those domains and mailboxes are yours to keep.

How long until something is live?

First campaign live in roughly two weeks. A full engine build and handover runs six to eight weeks, with weekly sessions training your team to drive it.

say yes, before you send.

The Multi-Persona Hypothesis is how we map a whole buying committee from public evidence, then write to each person about what they actually own. The full toolkit is free, and the prompts work as they are.

Michael Kyriakides

Founder, Prospectology

Six years in bootstrapped startups, then I launched Prospectology and worked with 12+ clients. Now I build outbound engines that clients own and run in-house. A person reviews every play before it sends, so the engine has your leverage and our judgement.

Own the engine.
