How to run outbound for a two-sided marketplace

Two-sided marketplaces are brutal to grow with outbound. You’re not selling a product to one persona. You’re trying to build supply and demand simultaneously, which means your outbound teams need to speak two completely different languages.

We’ve run outbound campaigns for 47 marketplace companies across fintech and insurtech. Most fail because they treat both sides with the same messaging, same cadence, same angles. That’s why their connect rates sit at 2-3%. The ones that work run separate plays entirely.

Why Two-Sided Outbound Is Different

A typical B2B outbound team targets one buyer persona with one problem. Marketplaces require you to build two acquisition engines at once.

Your supply side (providers, lenders, insurers, whatever you’re sourcing) cares about volume, profitability, and ease of integration. They want to know your marketplace moves actual deal flow.

Your demand side (borrowers, buyers, applicants) cares about pricing, availability of options, and speed. They want to know the supply side is real and competitive.

If you lead with “We have 200 lenders on our platform” to a potential borrower, they’ll say yes. If you lead with the same angle to a lender, they’ll ask where the borrowers are. You’re stuck in a chicken-and-egg loop unless you segment.

The best-performing marketplace outbound we’ve managed splits the motion completely. Supply and demand get different positioning, different metrics, different team structures.

Segment Hard, Message Harder

Start by mapping your two sides clearly.

Define each side’s pain: What does each persona lose sleep over? For a lending marketplace, borrowers lose sleep over approval rates and interest rates. Lenders lose sleep over credit risk, customer acquisition costs, and pipeline consistency. These are completely different conversations.

Create separate messaging playbooks for each side:

Supply side messaging focuses on: volume pipeline, margin quality, compliance, integration support

Demand side messaging focuses on: selection, terms competitiveness, speed, ease of application

This isn’t philosophical. When we ran outbound for a fintech marketplace, the supply-side script mentioned loan volume three times in the first 60 seconds. The demand-side script never mentioned volume at all. It led with approval likelihood and APR range. Same company. Completely different plays.

Measure each side separately. Your KPIs should be:

Supply: integrations completed, volume sent, margin captured

Demand: applications submitted, conversion to funded, average ticket size

Mixing these metrics will destroy your unit economics and make it impossible to know which side is actually working.

Build Social Proof Backwards

The chicken-and-egg problem is real, but most marketplace founders tackle it wrong. They try to solve both sides equally.

Here’s what actually works: Start with the side that has lower customer acquisition cost. Usually that’s demand. It’s easier to find 100 borrowers than 20 quality lenders. Get demand first, then use that volume as your main hook for supply.

When we pitch supply side now, we lead with “We have 2,800 pre-qualified borrowers waiting in our queue.” That’s real social proof. Without it, no lender wants to integrate.

The flip side: once you have supply (especially name-brand supply), your demand side messaging becomes: “We’ve integrated with Lender A, B, and C. You get five options instead of one.”

Use specific numbers, not vague claims. “Many lenders” doesn’t work. “Integrated with 7 institutional lenders” works. Even better: “Integrated with lenders funding up to $500K per applicant.”

Outbound Timing and Sequencing

Most teams run outbound at the same pace for both sides. That’s wrong.

Supply side needs longer sales cycles. Lenders, insurers, and other institutional providers need 60-90 days of conversation before they’ll commit resources to integration. They need to understand your volumes, your margins, your operations. Expect 8-12 touchpoints.

Demand side moves faster. Borrowers and end-users can make decisions in 2-3 weeks. Your cadence should be 5-7 touchpoints compressed into a tighter window.

We typically run:

Supply side: one touchpoint every 7-10 days over 12 weeks

Demand side: two touchpoints per week over 4 weeks

Same call center, different playbooks.

Infrastructure and Automation

Two-sided outbound needs segmented systems.

Your CRM should have separate pipelines for supply and demand with different stage definitions. Don’t use “Negotiation” for both a lender talking about integration requirements and a borrower deciding on APR. They’re different conversations at different stages.

Set up separate dialing campaigns. Most teams use one campaign with two lists in it. That kills your data. You need distinct campaigns so you can track which side is actually converting and at what cost.

Lead routing should be segmented. If your calling team is mixed, you need clear routing rules. Your most experienced reps should own supply-side initially. New reps can run demand-side campaigns while they’re learning.

Handling Your First 20% Conversions

When you hit your first real conversions, resist the urge to scale before you understand what worked.

We’ve seen teams nail 15 lender integrations then try to scale to 100 before understanding why those 15 said yes. Then they hit a wall. The 15 were willing to build custom integrations. The next 50 need pre-built connectors. Same play doesn’t scale.

Document exactly what changed between your first 5 conversions and your next 5. Often it’s small things: competitor mentions, new social proof, team structure changes.

Split-test messaging between sides ruthlessly. For supply: compare “volume-first” vs “margin-first” openers. For demand: compare “choice-first” vs “speed-first” openers. One will outperform the other by 30-40%.

Two-sided marketplace outbound isn’t a single motion. It’s two separate engines running in parallel, with different messaging, different pacing, and different success metrics. Most teams fail because they try to run one playbook for both.

We’ve helped marketplace founders go from 12% monthly growth to 35%+ by segmenting their outbound completely. The teams that perform best run what we call “asymmetric sequences,” where supply and demand are treated as entirely separate acquisition engines.

If you’re running outbound for a marketplace and it feels like you’re spinning, the problem probably isn’t your dialing. It’s your segmentation.

Nurturance runs specialized outbound for fintech and insurtech companies. We design two-sided marketplace plays, staff the calling teams, and handle the full pipeline. We work on pay-per-meeting basis, so you only pay for qualified conversations that actually move your business forward.
