Account-based outbound, run for you
A siege, not a spray.
We pick the companies most able to buy from you and never let go. Every ad, comment, connection, email and website visit lands on one account record, worked until they buy or tell us to stop, and what arrives on your calendar is a qualified, recorded meeting.
Trusted by 350+ teams in 20+ countries
How attention is earned
Eight touches, in order. Give before you ask.
On average it takes eight or nine touchpoints before a buyer gives you their attention. Most outreach fires one and gives up. We run the whole ladder, and before we ever ask for anything, you have already shown up in their notifications twice. That is why the invites get accepted.
The pool
Your market, always warm. A dead account never wastes a seat.
The working thousand is built from registers and hard screens, not scraped lists. Then it lives: a quiet account is benched with its history intact, a lookalike takes the seat, and the benched account returns the day a new signal fires. Going quiet is a timing problem, not a failure.
- Built, not bought. Every account carries the reason it qualifies and the source it came from.
- Screened, no exceptions. Headcount, revenue and deal-size minimums are applied before anyone is touched.
- Always full. Rotation keeps the pool at strength, so your pipeline never runs on stale names.
The research
Every account gets read. The company, and the person.
Open roles, frameworks named in their own job ads, expansions, listings, certifications. Then the human: what they said on stage, what they wrote, what they hold. The rule we work by: if a fact would be true of fifty companies on the list, it is not a hook.
The message
The anatomy of one message, measured.
50 to 125 words, the band where replies peak. Here is exactly what those words are spent on. Hover the split to see each block in the message.
Saw the SOC analyst role has been open six weeks now, and your ads name ISO 27001, so the framework is clearly real for you. My guess is the backlog lands on the two engineers you already have, though I could be wrong about that. Is filling that seat still the plan, or is outside coverage on the table? No worries at all if this is not relevant. Fellow ISACA member here.
In our reply data, sender-talk appears in 29% of ignored messages and 17% of replied ones. Every word about us costs a word about you.
Why it works
The numbers behind the method.
The research is staged: a hard screen before a seat, a dossier before a message, a live signal before an approach, and a fresh check minutes before writing. Then the message spends its words where the evidence says they pay. When a number is ours, we say so. When it is from a study, we name the study.

Coverage
The same account, five ways at once.
A buying committee is five people, and outreach will only ever have names for one or two of them. The ads reach the other three, and they keep running while the account is cold. So when a signal finally fires and we reach out, your company is not a stranger, it is the name they have been seeing for weeks.
Every touch, on every channel, lands on the same account record. That record is the asset, and it is yours.

Timing
Signals decide the first line, and the clock.
A signal is a company doing something that means they are in-market right now. Each one carries a freshness window and dictates what the first message opens on. We buy the detection, and we build the machinery that acts on it within hours instead of never.
First line opens on: the problem those pages describe
First line opens on: the first-90-days review every new hire runs
First line opens on: the maturity their new investors expect
First line opens on: the audit date, and what must be true before it
First line opens on: the open seat, and who carries it meanwhile
First line opens on: sector context, never the breach itself
One signal class we never use: weaknesses visible from outside. We read only what is public, and we never scan, probe or test a company that has not authorised it. That line is written into the system, not left to judgment.
The engine
Four steps, then a person.
When a signal fires, the engine qualifies the account, reads the company and the person, scores it 0 to 100 with a reason you can challenge, and drafts one opening line built on what it found. Then it stops.
Nothing sends until a person approves it. Sends are capped daily, and your customers and competitors are suppressed by list, not by memory. The score is not a black box: when your team disagrees with a reason, we change the rule.
Sector, size, a named contact
The company, the person, pages read
0 to 100, with a reason
One personal opening line
Capped daily. Customers and competitors suppressed by list, not by memory.
In and out
It lands where your team already works.
A signal comes in, the engine runs, a person approves. What arrives is finished work: an item on your PM board, the full record in your CRM, and a hot lead alert in your sales inbox in under 60 seconds. No new tool for your team to learn.
Or a website visit, a new security hire, a funding round, a compliance deadline.
The stack
Run by engineers, not by seats.
We buy what already works and build only the machinery between the tools, which is exactly the part you cannot buy.
The research and drafting engines. Every account read by AI, every line reviewed by a person.
Signal detection and enrichment, bought not rebuilt, spent only where the free lookup is not enough.
The list source, filtered by the hard screens before anyone is touched.
Delivery on real seats inside platform safety limits. We never automate LinkedIn directly.
Every delivered meeting recorded and transcribed. The transcript settles what qualified.
The account records, the approval gates, the weekly truth. Built, not rented, and your data leaves with you.

10 out of 10. Outstanding service. Roki and his team exceeded my expectations. He completely brought my LinkedIn profile to life — took the time to truly understand my ideal customer profile, something very few people get right. I have since commissioned my website, bio, and cold outreach.
I wholeheartedly recommend Rokibul for his remarkable scrappiness, strategic acumen in building win-win business models, and unparalleled expertise in driving outbound strategies. For anyone seeking to elevate their outbound sales efforts, Rokibul's services are not just beneficial; they are essential.
Roki is a true talent. He's versatile in his skillset yet always learning and growing. He's delivered results across the board while working for me in various capacities all across the digital marketing and sales landscape.
Rokib is not only a pleasant person to work with but he is also extremely results-driven. I've had the pleasure of working with Rokib on multiple occasions and there hasn't been a single time where he didn't achieve the promised result. If you require SEO or lead gen services I highly recommend working with Rokib.
Roki is one of a kind! Hard working and an absolute professional in lead generation and online marketing — but more importantly, a great personality. We worked with Roki and his team on content for all our social channels and our website, and can highly recommend it.
I have been working with Roki and his team at Prospect Engine for just over a year. They have helped with my outreach efforts and brought a lot more focus to the efforts. Roki's management of the team is second to none.
The first impression was vital. The 'feel good' factor that Roki demonstrated was phenomenal. Something special in the proposal from Roki and his team to help propel my organization to the next level — I highly recommend Roki and his team to any organization or entrepreneur.
Rokib and his team have been a pleasure to work with. They took the time to really understand what we were trying to achieve and delivered perfectly. Communication of the project status was continuous and we felt comfortable from day one.
Rokib always amazed me with his business insight and unique ways of solving problems. He is detail-oriented, target-oriented, ambitious, and a powerful service provider. Everything I learned about lead generation I learned from Rokib. He is an asset to any business.
Roki is an exceptional leader in the tech and AI space. His forward-thinking approach has led to the creation of cutting-edge apps, backed by a deep understanding of the latest technologies. His expertise, combined with his clear and effective communication, makes him a reliable and highly valued business partner.
Robikul delivers on what he promises — great personal service and passionate about growing and improving his business too. It's been a genuine pleasure working with him. Not only has he provided the service, but helped me understand more about using LinkedIn too.
Roki has been one of the greatest gifts to my team and a pleasure to work with. His attitude towards his work shows up in how much he aims to improve and successfully complete tasks. I feel extremely blessed to have been able to work with him! I would recommend his services to anyone.

Honest fit
Who we're for, and who we're not.
We do better work when the fit is right. If you're on the right side of this, let's talk. If not, we'll point you somewhere better.
A good fit
- B2B companies with a real offer and a deal size that justifies outbound.
- Founders and sales leaders who want meetings booked, not another tool to run.
- Teams selling to a definable ICP we can research and reach.
- 5–200 people, ready to take the calls we set.
Not a fit
- Pure consumer brands or anything without a clear B2B buyer.
- Anyone wanting a self-serve tool to operate themselves.
- Sub-$2k deal sizes where outbound economics don't work.
- Teams expecting overnight results. This compounds over weeks.
A note from the founder
I still take every first call. That's not a sales tactic — it's the whole idea.
I started Prospect Engine in 2020 as a cold-email shop. By 2024 we were writing more software than scripts. By 2026 it was clear the agency worth running is one where AI does the mechanical work and humans do the judgement work.
Ten clients at a time. I read every brief. I approve every proposal that goes out. When something breaks, you get me on Slack within the hour.
