Karton.ph: Marketing, Seller Onboarding, Sales Ops & Digital Comms for a Filipino-made Online Marketplace (Startup E-commerce)

-
Sales growth: +7% YoY (2019 → 2020)
-
Customer acquisition: +147% website customers
-
Seller growth: 83 → 139 sellers (Q1 → Q4 2020)
-
Channel conversion insight: Referral ~7.25% vs Social ~0.50%
-
Scale proof: Supported onboarding of 300+ sellers/merchants (2017-2021)
I helped grow a mission-led e-commerce marketplace by scaling seller onboarding, running conversion-aware marketing, and supporting sales operations across website, bazaars, and bulk gifting in a lean startup setup where strategy and execution happen at the same time.
At-a-glance
-
Role: Content / Marketing Strategist (startup scope: marketing + sales enablement + ops)
-
Tools: Google Analytics, Facebook Business Suite, Mailchimp (plus internal trackers)
-
Commercial streams supported: Website sales • Store/bazaar sales • Bulk gifting / corporate orders
The challenge
Karton needed to grow both sides of the marketplace at once:
-
Supply: onboard more credible Filipino sellers/products (fast)
-
Demand: increase customer acquisition + conversions through campaigns, partnerships, and content
-
Operations reality: fulfill orders, coordinate sellers, and support bulk gifting even with a small team
1. Seller onboarding + pipeline management (sales/partnerships)
-
Helped scale the seller base and onboarding pipeline—working across outreach, follow-ups, and onboarding readiness.
-
Seller growth accelerated in 2020, with 83 sellers (Q1) → 139 sellers (Q4) (net +56) as the marketplace expanded.
-
Managed active pipeline work such as June (+20 sellers), July (+12), August (+5) plus ongoing follow-ups and prospect conversations (categorized by stage).
What I Did
2. Marketing built for conversion (digital campaigns + ads)
-
Ran and supported campaigns that paired values-led storytelling (“Filipino-made”) with conversion thinking.
-
Used ad insights to identify what creatives and themes performed best; top ads in 2020 showed very strong ROAS patterns (30+ in the internal report), indicating highly efficient conversion campaigns for specific product themes.
-
Supported promo-code / influencer activation tactics as part of monthly marketing execution.
3. Analytics-driven iteration (GA + channel strategy)
Used Google Analytics snapshots to improve decisions on where to push:
-
Top channel for traffic: social media
-
Top channel for transactions: referral, with ~7.25% conversion rate
-
Social conversion rate: ~0.50% (high traffic, lower conversion → needed better landing flows + CTAs)
-
Flagged funnel friction: cart abandonment ~34–37% and 65–70% of traffic with no cart additions (led to recommendations like cart recovery offers, referral systems, and email/SMS tactics).
4. Sales + operations support (bazaars + bulk gifting + lean-team execution)
-
Supported sales during bazaars/physical selling, representing the brand and closing sales in-person (important for early-stage revenue).
-
Helped with operations for bulk gifting orders (prep, coordination, execution support), a critical startup revenue stream.
-
Contributed to process discipline around customer inquiries and order touchpoints (confirmation, delivery coordination, out-of-stock updates), which is essential to trust and repeat purchase.
5. Brand representation (speaking / media engagements)
Represented Karton publicly in speaking/media contexts to strengthen credibility and trust
FB live videos were later removed, but these posts show public representation.
Results

-
