Marketplaces live and die by two numbers: buyers on the platform and sellers on the platform. Lose one side and the other leaves. The chicken-and-egg problem is real. Most marketplace founders know this. Fewer know how to solve it with a system that scales both sides at once.
The AI Buyer and Seller Acquisition Agent does that. It runs acquisition on both sides of the marketplace. It qualifies leads, responds instantly, follows up at scale, and books onboarding calls for sellers while converting buyers into first transactions. Every layer runs together. Every layer runs around the clock.
The result is a marketplace that grows GMV every week without the founding team doing manual outreach on either side.
What Is the Marketplace Marketing Reality?
Two-sided platforms face a constraint that single-sided businesses never see. You have to market to two audiences at the same time. The messaging is different. The channels are different. The conversion paths are different. And the timing matters. Running buyer ads before you have enough supply damages trust. Running seller ads before you can prove demand makes onboarding hollow.
Trust is hard to earn on both sides. Buyers need to know that sellers are vetted and transactions are safe. Sellers need to know that the platform will deliver real customers and that the economics work in their favor. Building that trust on both sides at the same time takes more than a landing page and a logo.
Unit economics in marketplace marketing are often tracked wrong. The cost to acquire a buyer matters less than the GMV that buyer generates over time. The cost to acquire a seller matters less than the revenue that seller drives through the platform. Top-of-funnel metrics alone will mislead you. The system has to track downstream value on both sides.
What Does the AI Buyer and Seller Acquisition Agent Do?
The system handles five actions on each side of the marketplace. All connected.
It finds buyers and sellers. Paid campaigns run across Meta, Google, and other platforms. Buyer campaigns drive traffic into purchase funnels. Seller campaigns drive traffic into onboarding funnels. Each side gets its own targeting, its own creative, and its own landing experience.
It responds instantly. When a prospective seller fills out an application or a buyer sends an inquiry, a WhatsApp or ManyChat AI agent responds within seconds. No waiting. No missed messages. No lag between interest and engagement.
It qualifies and routes. The AI agent asks the right questions to determine fit. On the seller side, it filters for quality, category, and readiness. On the buyer side, it identifies purchase intent and matches to available supply. Bad fits on both sides are filtered out before they reach your team.
It follows up at scale. Hundreds of conversations happen at the same time. Every seller applicant gets followed up with. Every buyer who browsed but did not transact gets re-engaged. Nothing falls through the cracks on either side.
It runs around the clock. Nights, weekends, holidays. A seller who discovers your platform at midnight gets the same onboarding experience as one who applies at noon. A buyer browsing on a Sunday gets the same instant response as one shopping on a Wednesday.
Most marketplaces rely on manual outreach for sellers and paid ads for buyers with no system connecting the two. The AI Buyer and Seller Acquisition Agent replaces that gap with a trained agent that handles both sides, never sleeps, and never forgets to follow up.
One system. Both sides. Running 24/7.
How Does BLAS Work Inside the Agent?
The AI Buyer and Seller Acquisition Agent is deployed using the BLAS framework. Each phase has a specific job.
Build. The foundation deploys in days. Your marketplace gets a dedicated GitHub repo on Vercel. AI-generated copy is produced through Quill. Twelve creatives ship on day one for each side of the platform.
Launch. The highest-value funnel ships first. For most marketplaces, that is seller onboarding or buyer first-purchase. Supporting funnels layer in after the primary funnel hits its KPIs. Every dollar of ad spend is tracked from click to transaction.
Adapt. Six new creatives per campaign per week. Winners get challenged with new variations. Losers get replaced. The creative never goes stale on either side.
Scale. Runs in parallel with Adapt on validated winners. Budget increases are reversible. Spend goes up only on what is already working. Both sides scale together to maintain platform balance.
What Does This Look Like Live?
Claxton runs the full AI Agent system across verticals.
The business has closed over 9,000 deals through the system. Monthly recurring revenue exceeds $100,000. The system runs 24/7 with every layer connected.
The stack includes brand positioning, conversion funnels, paid traffic, social content, WhatsApp and ManyChat lead response, and automated follow-up. All of it runs as one system. For marketplaces, every component is duplicated across buyer and seller acquisition paths.
“The WRKS Online team built a system that puts cases on my calendar every day. My team just shows up and closes them.”
