Built a category-specific growth engine that unlocked $200K+ GMV in 75 days – without paid ads


Client Overview

Type of Marketplace: Peer-to-peer rental platform for event equipment (e.g., projectors, lighting, audio gear)
Stage: Early post-launch, struggling to gain transactional traction despite promising user signups
Geography: Multi-city rollout in Canada.
Founding Team Size & Stack: 3 founders (1 tech, 1 ops, 1 BD), no growth lead; built on a custom MERN stack
Buyer/Seller Dynamics: Hyperlocal, supply-heavy model — high equipment availability, low trust in transaction process. Majority of demand was event planners and small business owners with unpredictable frequency of need.


Role & Duration

Role: Fractional Marketplace Architect (GTM + Liquidity Strategy)
Duration: 90 days (plus light advisory for 60 days post-engagement)


The Challenge

This wasn’t a growth problem. It was a platform orchestration problem hiding inside a “why aren’t users converting?” question.

The client had strong early traffic and organic interest from both supply and demand — but platform transactions were stagnant. CAC was low due to word-of-mouth and niche partnerships, but conversion rates were painfully low on both sides.

  • Demand-side users (event organizers) would sign up, browse, but leave without booking.
  • Supply-side (owners of high-quality rental gear) were frustrated with inconsistent inquiries and started going inactive.
  • Liquidity wasn’t uniform — in some zip codes, there was oversupply. In others, there were zero credible listings.

And most critically: trust was the silent killer. Both sides hesitated at the point of transaction because they didn’t fully believe the platform could protect their interests.

Normal growth tactics — SEO, paid acquisition, email drips — would have made the problem worse. Until supply and demand were properly matched, every new user would be a wasted interaction.

The founders were in the weeds, trying to chase “more traffic,” but what they needed was a system that translated category-specific demand into local, trust-backed transactions — at scale.


Strategic & Operational Approach

1. Re-mapped marketplace dynamics around use-case liquidity, not geography

Rather than trying to match every user in every city, I identified the most transaction-ready use case: corporate offsite events.

  • These users had budget, recurring need, and low price sensitivity.
  • The same 12 types of equipment were repeatedly searched across cities.

We designed a category-first, geo-second matching system. We concentrated supply-side activation on those 12 SKUs in high-volume cities, creating instant perceived liquidity.

2. Redesigned onboarding for both sides to build trust and compress time-to-transaction

  • Supply onboarding was rebuilt around “instant book” capability and standardized terms, which we created through lightweight vendor agreements and insurance language.
  • Demand-side onboarding was focused on guided listings, curated bundles, and verified suppliers — not just a marketplace search bar.

Each user now saw clear next steps, real humans behind the profiles, and a reason to transact today.

3. Created a ‘liquidity unlock playbook’ for high-potential zip codes

Rather than try to “scale the whole map,” I built a repeatable 3-week growth sprint for new cities:

  • Week 1: Targeted supplier activation using manual outreach + curated profiles
  • Week 2: Launch offer for demand-side (free delivery or bundled pricing)
  • Week 3: First-transaction guarantee and case study content from local users

This process created intentional market density, not scattered growth. It’s how we built fast traction in 6 more cities — without burning capital.

4. Installed cross-functional rituals to avoid future ops overload

Most startups hire for ops after growth breaks the system. We did it in reverse.

I worked with the product and ops leads to build internal playbooks and Slack-based alerts for:

  • Vendor inactivity
  • Unbooked inquiries
  • Trust-risk signals (e.g., repeated disputes or refund requests)

This allowed the small team to maintain high-touch trust standards without bloating headcount or spinning up a “support org.”


Results & Business Impact

  • GMV grew from ~$25K/month to over $200K/month within 75 days
  • Vendor activation rate improved 3.1x (from 12% to 39%) due to clearer onboarding and real demand signals
  • Buyer first-transaction speed decreased from 9.4 days to 2.8 days
  • Trust-based conversion (where user rated platform 8+/10 for confidence) increased by 58%
  • Churn dropped significantly: Over 60% of vendors who transacted once came back within 30 days with new availability or reactivation

Most importantly, the growth was repeatable. By Month 3, the founders could launch in a new city using the “liquidity unlock” sprint without me. They no longer needed to brute-force early traction.


Why Partnering With Me Was the Advantage

When marketplaces stall, most founders throw fuel at the fire — more users, more ad spend, more campaigns.

But that’s noise without structure.
I don’t build noise. I build engines.

This project worked because I didn’t treat growth as a marketing function — I treated it as system orchestration.

  • I built trust into the mechanics of the platform, not the copy.
  • I treated unit economics like a diagnostic tool, not a spreadsheet artifact.
  • I designed onboarding for momentum, not just conversion.

That’s what real marketplace architecture looks like: understanding where your liquidity is born, and building systems that protect and expand it.


If you’re building a marketplace and tired of vanity growth, I’ll help you install the systems that turn liquidity into profit — and users into advocates.

This isn’t agency work. It’s operator-grade growth architecture — and it’s what your platform actually needs.
