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.
A replay of a real run, not a live one.
Talk to launch it. Watch a lead flow through every layer, a human approves, and results land in your inbox and CRM.
Real-time replies, meetings booked and what's working, for you and your team
No straw men. Clay is genuinely powerful. This is where each one actually fits.

Familiar and cheap to start. Does not scale past a few hundred leads, with no real personalisation.
The powerful no-code standard, endlessly flexible. But you need a specialist, credits burn quickly, and cost climbs the more you build inside it.
Brief it in plain English, stand it up in hours, own the whole thing. Built for a focused book, not a no-code playground.
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.
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.
Their whole engine, built from scratch. 30% LinkedIn reply rates, and doors opened at OpenAI, MoonPay, Vanquis Bank, Betfred and B&Q.

Michael Kyriakides · Founder, ProspectologyTick what you're paying for today, then see how a one-off engine you own compares.
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?
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.
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.
Same engine, our hands on the wheel. For teams who want the pipeline without operating the machine themselves.
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.
A number of meetings.
Anyone who does is guessing at your market with your money.
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.
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.
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.
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.
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.
Never. Email and LinkedIn only. We do not hold or enrich phone numbers for outreach, and cold calling is explicitly out of scope in our agreement.
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.
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.
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.
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.

You don't learn a tool stack. We build it, then guide you to drive it, over twelve weeks.
Inside your own stack, wired end to end, first campaign live in around two weeks. You watch, you don't build.
We guide you and your team to drive the engine, live, every week, with SOPs for every workflow.
Launch by voice, approve on the dashboard, replies land in your inbox. The engine is yours.
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.
First module drops soon. Leave your email and I’ll send it the moment it’s live. No spam, unsubscribe any time. How we handle your data.
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.
Book a call and we'll show you exactly what we'd build inside your stack, and how your team runs it.
Book a 30-minute call →Prospectology became OneID's RevOps partner and built their entire outbound engine from the ground up, generating 85 sales-qualified conversations in four months from zero.
KYC and identity verification is a saturated, highly competitive market, notoriously difficult to break into at enterprise level. OneID had no existing outbound infrastructure and not the manpower to build the engine themselves.
Prospectology found 35% more enterprise decision-makers than existed in 55/Redefined's CRM, verified and ready for outreach, in a single week.
55/Redefined had their top 100 enterprise dream list, but finding the HR-level decision-makers inside those accounts was near impossible. Their sales team was spending 10+ hours a week manually researching contacts.
