WHY THIS MATTERS
Forces threatening marketplace trust at scale
Fraud growth, onboarding abandonment, and the accelerating complexity of marketplace trust and safety are compressing platform economics and threatening the seller and buyer relationships that drive Gross Merchandise Value, impacting every marketplace COO and CFO.
FRAUD LOSSES
$10.2M
Average annual fraud loss for an ecommerce marketplace, with 79% of marketplaces reporting fraud is rising year over year.
Ravelin, Ecommerce Marketplace Fraud Trends, November 2025
ONBOARDING ABANDONMENT
10%
Marketplaces that activate vendors within 48 hours keep abandonment below 10%; slower onboarding pushes drop-off sharply higher.

CLIENT SPOTLIGHT
One hybrid model built for scale
How a hybrid onboarding model enabled a leading ecommerce marketplace to activate 300 new sellers in a single quarter without sacrificing verification quality.
A leading ecommerce marketplace needed to scale seller onboarding rapidly without allowing verification quality to slip. The onboarding process had to work at volume and speed while maintaining the identity and compliance checks the platform required.
We deployed a hybrid onboarding model combining structured human verification with process automation. Quality frameworks built our domain harness, running multi-brand, multi-seller operations at ensured verification standards were maintained throughout the ramp.

Capabilities
Built once, deployed across every retail engagement
Capabilities brought to every retail engagement — not tied to a single solution, but running across origination, delivery, and recovery wherever the operation needs them.
Redesign the operating model before the cost does it for you
Firstsource diagnoses the structural failure modes inside retail customer experience operations — fragmented contact drivers, misaligned workforce models, and technology that was bought but never operationalized. Engagements run from a rapid diagnostic through to a time-bound transformation roadmap with named milestones. Every recommendation is tested against live delivery evidence, not benchmarks.
Commerce technology that runs
Firstsource architects and delivers end-to-end solution builds across partner tech and stitched into domain and context intelligence so the technology operates at scale to drive real outcomes. Implementation includes integration across fulfilment, CRM, and loyalty systems, with quality assurance built into the delivery model. Retailers get a functioning stack, not a proof of concept.
Every interaction becomes intelligence that drives the next decision
For retail AI, the data layer—not the model—now decides accuracy, safety, and compliance. We operationalize that layer end-to-end so your teams ship reliable, compliant AI faster, at scale.
- Governed, integrated data with PII protection
- Faster iteration via expert-graded annotation, human-preference tuning, and continuous drift detection
Resolve in one interaction — no handoffs, no queues
Firstsource integrates document processing, workflow automation, and order management directly into retail back-end systems — so frontline advisors have everything they need to resolve a contact at first touch without escalation or manual re-keying. The output is measurable
Campaign production at the speed retail requires
We run AI-native marketing operations for retailers that need to move faster than in-house teams can sustain — covering pre-acquisition content production, multichannel campaign delivery and promotional creative at scale. Output volume is not capped by headcount because the production model is built around AI-assisted workflows with human quality control at each stage. Retailers get content that they can take to the bank, delivered on the cycle times their competitors cannot match.
PROOF OF DELIVERY
Real marketplace outcomes. Distinct metrics that matter.
Engagements demonstrating scale, quality, and trust discipline, each measuring a different operational outcome.

TESTIMONIAL

We have come so far in this time and it's really down to all of your hard work. It's also worth pointing out that our competitors didn't make it onto any of the lists below. Thank you to everyone who has been involved in this journey of transformation.
You took over a significant backlog with zero experience of our business, right at the start of Retail Peak and Black Friday. You took control, spoke to customers without them having to wait. Being there for customers made a massive difference, taking us to a whole new level.
