MarketplacesWhat stands in the way

A marketplace is only as strong as its trust layer. Verification, protected payments and dispute handling are the product, and supply or demand leaves as soon as one of them fails.

01The pressure

Where marketplaces lose supply and demand

Five problems that are common in this industry, and what we build against each one.

01

Sellers who never list

Complicated onboarding kills supply before it starts.

What we build

Fast seller onboarding

We build onboarding with verification, catalogue import and guidance to a first listing.

02

Payments held together with scripts

Manual payouts create errors and delays that sellers remember.

What we build

Split payments and payouts

We build protected payments, splits and scheduled payouts as infrastructure.

03

Trust left to chance

Without verification and dispute handling, buyers hesitate.

What we build

Trust systems

We build verification, reviews and dispute flows into every transaction.

04

Search that hides supply

Poor discovery leaves good listings unseen.

What we build

Structured discovery

We build structured catalogues, search and ranking that surface good listings and can be tuned by your team.

05

Operations by spreadsheet

Take rates, vendor performance and disputes are tracked by hand.

What we build

Operations consoles

We build operations consoles for moderation, finance and vendor performance, with the numbers in one place.

02All in one studio

Everything we build for marketplaces

Design, engineering and AI in one team, so the website, the apps, the back office and the agents are made to work together.

04Next step

Start with the problem that costs you most.

Tell us which side leaves first today and why. We will show you the system that keeps them.

What to bring

  1. How the process runs today, in a few lines
  2. The systems it has to connect to
  3. Who decides, and your timing
05Before the first call

Asked before the first call

Short answers to the questions that usually come first. The rest is settled in scoping.
