In this case study, I’ll go over how I built and delivered the Discoverr virtual conference for $9K vs $20K projected, with cost-per-seller at $1,125 vs $2,500 forecast.
What CMO-tier budget management looks like with startup-team economics
When Deliverr decided to run their first virtual seller conference in summer 2020, they projected a $20K budget and a $2,500 cost per new seller acquired. I built the entire event for $9K and brought cost per new seller to $1,125 — 55% under budget, 55% more efficient than forecast on the same metric, and 38% multi-channel activation vs the 31–32% baseline (~20% relative lift) — outcomes scaled while spend dropped.
That dual outcome is what a fractional CMO + startup-team economics actually looks like.
The numbers
| Metric | Projected | Actual |
|---|---|---|
| Budget | $20,000 | $9,000 — 55% under |
| Cost per new seller | $2,500 | $1,125 — 55% more efficient than forecast |
| Registrants | 3,000 | 3,047 — hit goal exactly |
| Attendees | (no projection) | 1,241 — 41% attendance rate |
| Multi-channel activation rate (Discoverr cohort) | (no projection) | 38% — vs 31–32% baseline |
| First-touch merchants attributed to Discoverr (Q4 2020)* | — | 158 |
*Cost-per-new-seller measured against 8 first-order conversions within the first month post-event, against actual $9K spend (vs. $20K projected).
Let’s zoom out a little, as these are CMO-relevant numbers more than just event ops. Specifically, budget management and cost-per-acquisition on a high-stakes campaign that Deliverr ran twice (2020 + 2021).
The math
55% under projected spend
| Value | |
|---|---|
| Projected spend | $20,000 |
| Actual spend | $9,000 |
| Reduction | $11,000 |
| % reduction | $11,000 ÷ $20,000 = 55.0% |
55% more efficient than the cost-per-acquisition forecast
| Value | |
|---|---|
| Projected cost per new seller | $20,000 ÷ 8 first orders = $2,500 |
| Actual cost per new seller | $9,000 ÷ 8 first orders = $1,125 |
| Reduction | $1,375 |
| % reduction | $1,375 ÷ $2,500 = 55.0% |
What was Discoverr?
Discoverr was Deliverr’s annual virtual eCommerce conference. The 2020 inaugural event ran 6 sessions across 17 speakers and 6 hours of content over two days. I built and ran it from scratch, from the landing page, speaker coordination, marketing, attribution, and post-event repurposing.
Deliverr brought me back to run it again in 2021 as a freelance return engagement: 19 sessions, 40+ speakers, 10 hours of content (about 3× the scale), on similar lean budget discipline.
Both events ran under one of the smallest event teams in the B2B eCommerce ops space.
Why this matters as fractional-CMO proof
Most marketing case studies surface output metrics — pageviews, content volume, signups. Those matter. But the big win was budget management; doing what a full-marketing-team-with-vendor-stack would do, on a fraction of the spend, without sacrificing outcomes.
Discoverr is the cleanest single proof of that pattern in my career. The forecast was set by the in-house team (not me); the delivery was on me. I came in 55% under projected spend AND 55% more efficient than the cost-per-acquisition forecast — meaning the $9K I spent didn’t just save money, it produced *more conversions per dollar* than the $20K projection assumed.
“Be Lean: 10/10. Rachel has been able to do more with less just about everywhere in her role… the amount of content Deliverr pushes out on weekly basis exceeds that of any other players in the space. And we do this with one of the smallest teams.”
– Michael Krakaris, Co-Founder, Deliverr
The operational story behind the virtual conferences
The case study above is the budget-and-outcomes story. If you want the operational detail (how speakers were coordinated, what software stack worked best, what scheduling rules to apply, what marketing channels drove registrations, what to repurpose post-event) I wrote two articles covering my learnings at the time:
- Lessons from organizing a 2-day virtual eCommerce conference (2020): Planning phase, landing page creation, event organization, marketing strategy, execution tips, post-event work. ~3,500 words.
- Lessons from organizing the 2nd annual Discoverr Conference (2021): What changed year-over-year, software upgrades (Livestorm → BigMarker), session-length reductions, freelancer contracting lessons. ~3,500 words.
Both are written for other event organizers running their own virtual conferences. They’re operational, and so should be useful if you’re sizing how to do this yourself, or evaluating someone who claims they can.
What this engagement says about how I work
Lean execution, not just lean budgets. The 55%-under-budget number alone could mean “she shipped a worse event for less money.” The 55%-better-cost-per-seller number is what proves outcomes scaled while spend dropped. I’ve focused on budget discipline and operational efficiency at the campaign and channel level at every fractional CMO engagement since then.
The forecast came from the team; the outcome came from me. Deliverr’s in-house team set the $20K / $2,500-per-seller projection based on industry benchmarks. I owned the delivery, including sourcing speakers, building the landing page, running the comms, choosing the software stack, and post-event repurposing. CMO scope from a flexible freelance contractor.
Repeat business is the truest proof. Deliverr brought me back the following year to run it again at 3× the scale. That shows how successful our first run was when I was handling their marketing.
