Case Study | Yourpeptidebrand.com | 5.5 months
How we built a $2,237,841 B2B business from $0 in 5.5 months using only two channels.
A live, ongoing case study of the methodology we build for fuelmarketing.systems clients — applied first to our own business.
$2,037,841 revenue and $108,750 MRR attributable to the two-channel system. $200K and $20K MRR seeded from existing Rocktomic client introductions. Full breakdown below.

November 2025
The setup
Yourpeptidebrand launched with a clear thesis and a blank slate.
What we had
- Two co-founders (Aaron Peden, Ben Morgan)
- One operations hire (Alyson Jensen)
- A product catalog of 66 RUO research peptides
- A white-label dropship operations infrastructure
- A B2B membership pricing model ($297/mo Core, $497/mo Premier)
- A small list of warm contacts from Rocktomic, a parallel B2B brand we operate
What we did NOT have
- Any organic traffic
- Any cold email infrastructure
- Any paid advertising channel
- Any sales team
- Any inbound demand
- Any case studies or social proof
- Any brand recognition in the space
The objective: prove that two channels — SEO content at scale and cold email infrastructure — could build a B2B business from zero, with no paid acquisition.
The problem
In November 2025, the conventional B2B launch playbook looked like this:
- Raise venture capital
- Hire a 5-person sales team
- Build outbound with SDRs at $80K/year each
- Run paid ads at $300+ CAC
- Wait 18 months for product-led growth to maybe work
We were not going to do any of those things.
The cost structure of that playbook requires $3–5M in venture funding to survive 18 months. We had no funding, no SDRs, no paid ad budget, and no patience for an 18-month timeline.
The alternative we tested: a two-channel system where infrastructure does the work humans usually do.
- SEO content publishes 24/7 without hiring writers continuously
- Cold email infrastructure prospects 24/7 without hiring SDRs
If the system worked, it would prove that the B2B service business launch playbook could be fundamentally restructured around infrastructure rather than headcount.
It worked.
The strategy
Two channels. No exceptions for the first six months.
Channel 1: SEO Content at Scale
Why: Organic traffic compounds. Every article compounds in search rankings while live, building topical authority that performs without per-click cost. By month 6, articles published in month 1 are still ranking and generating leads.
Approach: Build a Standard Operating Procedure (SOP) for content production that produces ranking-grade articles consistently, then publish on a sustained cadence.
Detail: The first iteration of the SOP was version 4.1. We iterated through 4.5, 4.6, and 4.7 over the first 4 months. Each iteration tightened quality checkpoints based on actual ranking outcomes.
Channel 2: Cold Email Infrastructure
Why: Cold email reaches buyers who would never search for us. It’s the fastest way to test positioning across multiple buyer profiles. And it scales by adding mailboxes, not headcount.
Approach: Build dedicated cold email infrastructure (domains, mailboxes, deliverability layer) before any campaign launches. Segment the addressable market into distinct buyer avatars. Send avatar-specific sequences from properly-warmed infrastructure.
Detail: We provisioned 540 mailboxes across 128 domains during the buildout. By month 4, we’d identified 31 distinct buyer avatars across our target market.
What we explicitly did not do
- Paid ads on Google, Meta, LinkedIn
- Hire SDRs or sales reps
- Run podcast ads or sponsorships
- Buy email lists or attempt LinkedIn automation
- Run influencer partnerships
- Founder-led BDR work after the warm Rocktomic introductions in week 1
Phase 1 — Foundation
Months 1–2 | November 2025 – January 2026
Activities
- Cold email infrastructure provisioning (540 mailboxes warmed, 128 domains acquired and configured)
- DNS hardening: SPF, DKIM, DMARC across all domains
- SOP v4.1 deployed for first content batch
- First 5 articles published (BPC-157, Tesamorelin, CJC-1295 Without DAC, NAD+, GHK-Cu)
- Rocktomic client base notified of Yourpeptidebrand launch (warm channel — disclosed)
- Buyer avatar mapping (31 avatars identified across functional medicine, anti-aging clinics, research labs, supplement brands)
- Master 7-step cold email sequence developed and tested
Outcomes by end of Phase 1
- $20K MRR from Rocktomic warm seed
- $200K in initial revenue
- Cold email infrastructure ready for activation
- First articles indexed (Tesamorelin showed 19.8 min average time on page from initial test traffic)
- Avatar 01 (Functional Medicine MDs) deployed as first cold email campaign
Lessons learned
- DMARC at p=reject killed initial deliverability. Open rates dropped to 6%. Pivoted to p=none during testing. Open rates jumped to 75%.
- Article quality at SOP v4.1 was good, but internal linking was inconsistent. Built the Internal Link Auditor plugin to enforce 11–22 link target.
Phase 2 — Activation
Months 2–4 | January 2026 – February 2026
Activities
- Cold email campaigns scaled to 5–7% of total mailbox capacity (intentionally throttled to monitor deliverability)
- SOP iterated to v4.5 then v4.6, tightening quality checkpoints
- Featured Image Generator plugin built (Puppeteer-based, replaced manual image work)
- SOP Enforcer plugin built (automated 14 quality checkpoints)
- Freshness Monitor plugin deployed for auto-refresh at 75 days
- UTM persistence library built for full-funnel attribution
- Looker Studio dashboard live with channel-level conversion tracking
- Conversion layer rebuilt: channel-specific routing, attribution architecture, and conversion event configuration deployed (separating cold email funnel from organic funnel without rebuilding the underlying pages)
Outcomes by end of Phase 2
- Cold email driving 5,202 site sessions/month
- Initial cold email conversion rate: 0.21% (low — landing page mismatch identified)
- Cold email conversion rate after landing page rebuild: 4.1% (19x lift)
- Organic traffic beginning to compound
- $87.5K MRR achieved
- Total active customers: ~150
Lessons learned
- Landing page mismatch was the single biggest conversion killer. Generic homepage destinations for cold email visitors converted at 0.21%. Channel-specific landing pages converted at 4.1%.
- Quality control on content production required automation. Manual review didn’t scale past 10 articles.
Phase 3 — Compounding
Months 4–5.5 | February 2026 – April 2026
Activities
- SOP v4.7 finalized — 14 quality checkpoints with full automation
- Cold email avatar coverage expanded
- Reply management process formalized (4-hour classification SLA)
- Conversion layer iterations based on actual funnel data
- Customer success processes built for onboarding and retention
Outcomes by end of Phase 3 (current)
- $128,750 MRR (sustained)
- $2,237,841 cumulative revenue (recurring + product)
- 247 active B2B customers
- Cold email at 5–7% of full capacity (15–20x runway remains)
- Articles published: 5 (intentional — proving the conversion layer before scaling content)
- Average time-to-rank for new articles: 7–14 days
- Organic traffic conversion rate: 6.31%
Where it stands today
The system is operating at fractional capacity. We’ve validated the unit economics, the infrastructure, and the conversion architecture. What remains is scaling each channel to full utilization — which is what we now offer to B2B service businesses through fuelmarketing.systems.

What we got wrong
A case study without failures isn’t a case study. It’s marketing. Here’s what we got wrong.
DMARC at p=reject killed deliverability for two weeks
Initial DMARC policy was too aggressive. Open rates dropped to 6% across all 128 domains. We pivoted to p=none during testing, then progressively tightened back to quarantine. Two weeks of cold email volume were essentially wasted while we diagnosed.
Lesson: Always start cold email infrastructure with p=none, then tighten. Never deploy p=reject before you’ve confirmed deliverability across all domains.
Landing page mismatch cost us 4 weeks of conversions
We sent cold email visitors to Yourpeptidebrand.com’s homepage — which was built for organic visitors with high search intent. Cold email visitors arrived with different context and bounced in 13 seconds. Conversion rate: 0.21%. We rebuilt with channel-specific landing pages. Same email volume, conversion went from 0.21% to 4.1%. That’s a 4-week period where we drove 5,000+ visits that produced 11 conversions. Should have been ~200.
Lesson: Channel and landing page must be designed together. Generic destinations destroy cold email ROI.
SOP v4.1 underspecified internal linking
Articles published under SOP v4.1 had 2–5 internal links each. Articles in SOP v4.5+ have 11–22. Performance differential was significant. Earlier articles still rank but at lower positions.
Lesson: Internal linking is not optional. It’s a ranking signal AND a conversion driver. Auto-enforce the link target via plugin.
What this means for your business
Yourpeptidebrand is a working demonstration that:
- A B2B service business can be built from zero to $100K+ MRR in 6 months without paid ads or a sales team — IF the underlying infrastructure is built correctly.
- The two channels that did the work for Yourpeptidebrand are reproducible. They’re not contingent on a founder’s network, a specific niche, or a moment in time.
- The infrastructure has 15–20x runway built in beyond what produced these numbers. Every client we deploy this for is operating against significantly more capacity than Yourpeptidebrand used.
What the numbers project for you
If your business has:
- $1M–$10M in annual revenue
- An ACV above $10K
- An existing sales process
- A B2B addressable market of 5,000+ companies
Our 12-month projection ranges:
- Conservative: $1.5M – $2.5M new attributable revenue
- Expected: $2.5M – $4M new attributable revenue
- Aggressive: $4M+ new attributable revenue
These projections come from a custom model that takes your specific business inputs (TAM, ACV, sales cycle, close rate) and runs them through our infrastructure benchmarks. You see the full projection in the custom proposal we generate from your application.
