Attention B2B Companies

Predictable, Performance-Based Pipeline from Cold Email

We build and deploy a complete cold email system for your business, sending 50,000–200,000 offer-driven emails over 60 days to your ideal prospects.

You only pay for each qualified & shown meeting.

"The technical depth, the testing, the dedication to getting the system to actually convert — it's real work and it shows. And the incentives are simply right."

Your Warm Audience Has Hit Its Ceiling

Referrals, word of mouth, and your existing network have a natural limit. At some point, everyone who knows you already knows you.

You need a pipeline channel that is consistent, measurable, and fully in your control.

Cold email means reaching your ideal prospects directly, every day, with the right offer, at the right moment, to earn a meeting.

You might have tried it before and failed, for these specific, fixable reasons:

You're Pitching a Warm Offer to Cold Strangers

A referral comes in with trust already built. A cold stranger has zero context and zero reason to keep reading.

Warm framing, claims, and language are invisible to cold traffic. Most people never change anything and wonder why nobody responds.

Your Infrastructure and Lead Lists Were Built to Fail

Cold email is a volume game. A cheap domains and inbox setup means you barely send enough to matter, and what you do send lands in spam.

Most companies also pull from the same generic lists as everyone else, without any enrichment, qualification, or prioritization. As a result, they reach the wrong people at the wrong moment.

You Used AI to "Personalise" the Emails

People can tell. It becomes counterproductive fast.

AI belongs in prospecting, finding the right companies and the right people at the right moment. Not in the copy, and definitely not as your main weapon.

Your Agency Was Incentivized by Activity, Not Revenue

They billed the retainer whether it worked or not. They optimized for emails sent, not meetings closed.

When the incentives are wrong, the outcomes follow.

The Cold Offer System

Four Steps. One Complete System.

01
Build Your Cold Offer

Cold email puts your offer in front of people who have never heard of you and did not ask to hear from you. It should immediately answer:

  • What will they get (The Outcome)
  • When will they get it (The Time frame)
  • What happens if it doesn't work (Risk Reversal)

We build this first, and work to perfect this for the whole pilot, based on the results we get.

02
Deploy Real Infrastructure

Most cold email campaigns never reach the inbox. We make sure they do with enterprise-grade infrastructure. Exact numbers change based on your needs.

  • 10 branded sending domains. Your main domain never touches a cold campaign.
  • 49 warmed inboxes per domain.
  • 5 emails per inbox per day to mimic human behaviour.
  • 14-day warmup on every inbox and SPF, DKIM, and DMARC fully configured.
  • Private sending servers to ensure max deliverability.

03
Build Your Lead Pipeline

The same lists from the same tools yield the same results. We like to go the extra mile.

  • We pull every company with a live, SSL-validated domain, from the entire internet.
  • We identify the decision makers, then enrich and qualify every record.
  • We run every contact through a waterfall of multiple email providers, until a verified address is confirmed.
  • We layer in buying signals: open roles, recent funding, technology stack, headcount growth, so we prioritise who we reach and when.
  • We verify each record once again before sending.

04
Launch, Manage, Optimize

From launch, we run full day-to-day ops.

  • Up to 10 messaging angles in parallel.
  • 4-6 variants upfront + 1-2 follow-up emails.
  • Test rapidly to see what works and double down.
  • Handle replies as your professional SDR.
  • Book confirmed meetings straight in.
  • Send pre-call assets so prospects show up warm and ready.

Cold Offer Built First

Before a single email sends, we define the specific framing that makes a cold stranger want to respond. Built from scratch for people who have never heard of you.

AI for Prospecting, Humans for Copy

We use AI to find the right companies and the right people at the right moment. Humans write the copy that converts. That distinction is exactly what most agencies get backwards.

You Own Everything We Build

The domains, inboxes, lead lists, and copy all go into your accounts from day one. No black box. No lock-in. No dependency on us after the pilot.

Performance-Based Model

No retainer. You pay a flat rate per qualified meeting that shows up. The risk is entirely ours. If nothing shows up, you pay nothing.

Hi, I'm Shahar

I finished my service, traveled the world for a year, volunteered, worked and generated over $100,000 for businesses with email.

I became obsessed. That led to Flowroots.

We build cold outbound systems for B2B SaaS with offer-driven copy, on a pay-per-call model.

You only pay when a call shows up, which means our incentives are fully aligned. I win when you win, and that makes me a partner in your pipeline, not a vendor on your payroll.

I'm data-obsessed, I move fast, and I don't mess around. If you're ready to scale without hiring a team of SDRs, let's talk.

Frequently Asked Questions

What does it cost?
  1. Monthly tech fee: $500-$1,000, based on your goals and needed scale. Includes domains, warmed inboxes, data sourcing, enrichment, contact verification, and lead qualifying. We do not cut corners here. We build it right and with long-term thinking from day 1.
  2. Performance fee: a flat rate per qualified meeting that shows up. This is where we can earn.
How is this different from other cold email agencies?

Most agencies write a few emails, hand you a login, and call it lead generation. We build the cold offer first, deploy real infrastructure, source leads from the entire internet, handle every reply on your behalf, and run a pre-call sequence before every meeting. You pay per result, not per month.

What counts as a qualified meeting?

We define this together before a single email goes out. This is what the call is about.

Every booked prospect goes through a pre-call sequence so they show up warm and ready, not cold and unprepared.

What if meetings don't show up?

You pay nothing. We don't have case studies yet, so the risk is entirely ours. You only pay when qualified prospects show up. Pay-per-shown means exactly that, shown, not booked.

How long until the first meetings come in?

First calls typically arrive within 2–4 weeks after launch. That includes the infrastructure setup.

Do we own the system you build?

Yes. Everything — domains, inboxes, lists, proven angles, SOPs — goes into your accounts from day one. It is yours whether we continue working together or not. No lock-in and no black box to hand back.

How do you find prospects?

We source from the entire internet, using the latest AI technology to scale the process and maintain quality. We enrich every record with the right decision maker, run waterfall email verification, layer in intent signals, and triple-verify every contact before anything sends.
