Marketers:
50+ B2B SaaS clients, agency sold in 2021.

Challenge

In 2017, B2B SaaS founders in Eastern Europe had a recurring problem. Their products were as good as their Western peers'. Their pipelines weren't. Most relied on a thin trickle of inbound, a founder doing LinkedIn DMs after midnight, and an outsourced cold-email service that burned through domain reputation in two quarters.

What was missing wasn't tactics — it was an agency that ran demand-gen the way a senior B2B SaaS founder would run it themselves. ICP-disciplined, sequence-tested, copy-driven, with a real handover into a CRM rather than a spreadsheet of unverified emails.

Approach

The agency thesis

Marketers was built on three commitments:

• Founder-grade work. Account leads were senior. ICP work happened in person with the founder, not via a Typeform.
• Layered demand. No single-channel campaigns. Every account ran LinkedIn + cold outreach + content distribution as a single feedback loop.
• Owned data. Sequences, replies, conversion rates lived in the client's CRM from week one. Nothing held hostage in agency tooling.

The playbook

Each client engagement followed the same shape, refined over four years and 50+ accounts:

• ICP build (week 1) — workshops with the founder, sample-of-10 prospects walked through manually, written ICP doc with named persona triggers.
• Channel mix (week 2) — LinkedIn outbound for senior personas, cold email for high-volume mid-market, content distribution for category creation.
• Copy A/B (weeks 3–6) — every sequence ran 3–4 copy variants in parallel, winner promoted weekly, losing variants archived with the reason.
• Pipeline review (weekly) — 30-minute call, three questions: which accounts replied, which sequences won, what changes next week.
• Handover discipline — meetings booked into the founder's calendar, prospect history visible in their CRM, no agency-only dashboards.

Founder-led category content

The clients who scaled fastest weren't running the most outbound — they were running outbound + founder content in concert. We helped founders write LinkedIn posts that outbound prospects actually saw before the first DM. The first reply rate doubled when the prospect had read three of the founder's posts in the prior week.

What we ran

• 50+ B2B SaaS accounts across DevTools, MarTech, Vertical SaaS, AI/ML platforms, fintech back-office.
• Multi-domain cold-email infrastructure with proper warmup, deliverability monitoring, and a hard rule against any volume that put the client's primary domain at risk.
• LinkedIn outbound at senior persona level — Sales Nav-driven, persona-pivoted by trigger event, copy-tested weekly.
• Founder content programs — ghostwritten or co-written LinkedIn posts that compounded credibility while outbound was running.
• CRM hygiene playbook — sequences, replies, meeting bookings flowing into HubSpot or Pipedrive, fully audit-able.
• Quarterly playbook reviews — dropping channels that stopped working, doubling on the ones that did.

Results

Marketers grew from a single founder to a team of operators across four years. Client retention measured in years, not quarters. Several portfolio clients reached Series A and Series B with Marketers' demand-gen still running. The agency was sold in 2021.

The numbers we will quote here are the ones we own without ambiguity: 50+ B2B SaaS clients, four operating years, sold 2021. Per-client outcomes belonged to those founders and remain confidential. The bigger result is the playbook — refined across 50+ accounts, now ported into MIR · Agency engagements with the same discipline.

Stack & tooling (then and now)

What this engagement looks like for you

Today we run the same shape — modernized for the AEO era — for B2B SaaS founders who need pipeline, AI-tool startups who need category presence, and fintech companies who need senior outbound that doesn't damage their brand. Senior account lead, multi-channel by default, founder-content layered on top, owned data in your CRM.

If you've been burned by an agency that handed you a dashboard and a 9% reply-rate spreadsheet, this is the opposite of that.
