Custom B2B platforms · Marketplaces · Classifieds

Build the platform that connects your market.

We design and build vertical exchanges, classifieds products and B2B marketplaces — from the first release to mobile apps, community, payments and AI. One product, consistent business rules and the tools needed to operate it.

  • Web and mobile product delivery
  • Business accounts, listings and moderation
  • Community and AI scoped deliberately

Who we build for

Three scenarios. Distinct business models.

We start from how participants discover products, connect and trade — rather than assuming every marketplace needs the same modules.

01 / B2B

Agricultural and food exchange

Buy and sell listings, quantities, locations, product categories, availability, B2B contacts and multi-country operation.

02 / B2B

Vertical B2B marketplace

Organization accounts, team permissions, supplier catalogs, RFQs, counterparty verification and trading workflows.

03 / B2B

Classifieds with a mobile app

Fast posting from a phone, photos, saved searches, notifications and consistent data across the app and website.

What we can design and deliver

More than listings. A complete product and operating model.

Scope follows your strategy. Not every capability belongs in the initial release; community and AI need a clear purpose, operating cost and safety controls.

Marketplace and business accounts

Buy/sell listings, categories, filters, search, languages, geolocation, organization profiles and role-based permissions.

iOS and Android apps

Mobile listing creation, photos, alerts, saved offers and consistent data through a shared backend API.

Community and communication

Discussions, reactions, reports and moderation. Private buyer–seller messaging is a separate product decision, not an assumed part of public community.

AI-assisted listing creation

Draft descriptions, structured data and illustrative images with review controls and a clear boundary between generated imagery and real goods photos.

Operations, monetization and analytics

Admin workflows, moderation, promotions and payments, process oversight, listing quality and user-journey measurement.

Integrations and expansion

Existing company systems, partner APIs, catalog imports, market expansion and safe evolution of an operating product.

A shared API, consistent permissions, listing states and exception handling matter more than duplicating domain logic across mobile and web.

Experience demonstrated in a real product

KILOGRAM — marketplace, mobile and AI.

KILOGRAM combines an agricultural trading website, a mobile app, a centralized listings backend and operator tooling. Its published case study documents the core product decisions.

  • One listing model and API rules shared by web and mobile.
  • Listing workflows, discovery, geolocation and notifications.
  • Public community discussions and moderation capabilities.
  • Controlled AI processes, including illustrative listing imagery.

Verified case-study scope: public discussions are not private messaging; we do not claim unverified sales, user-growth or revenue results.

How we work

From an idea to a platform ready to evolve.

We establish trading rules, audiences and the first measurable outcome before committing to a sequence of releases.

01

Discovery and initial scope

Who posts listings, who buys, how do contacts, verification, monetization and moderation work?

Workflow map and MVP priorities

02

Product and architecture design

User journeys, data model, APIs, permissions and operational workflows.

Prototype, architecture and delivery plan

03

Build and release

Web platform, backend and operator console, with mobile and extensions according to the agreed scope.

Tested product with quality gates

04

Measure and improve

Track listings, contacts, engagement, AI costs and feature outcomes to guide the roadmap.

Evidence-led release priorities

Marketplace development cost

What shapes the budget?

There is no single fixed price for every marketplace. A basic classifieds site and an enterprise B2B exchange differ substantially in workflow complexity and operational responsibilities.

Discuss scope and budget

Main scope and cost drivers

  • 01Listing types, permission models and trading journeys.
  • 02Web, mobile and administration deliverables.
  • 03Search, location, localization and partner integrations.
  • 04Payments, subscriptions, featured listings, invoicing and settlement.
  • 05Moderation, private messaging, community and managed AI costs.

We estimate the initial release, optional extensions and ongoing operations separately. Discovery produces an appropriately scoped proposal rather than a misleading generic price.

Questions before commissioning a marketplace

How much does it cost to build a B2B marketplace?

Cost depends on listing rules, roles, trading workflows, app surfaces, payments and integrations. We define a first release and then provide a tailored estimate and extension roadmap.

Can we launch the website before the mobile app?

Yes. A shared data model and backend API allow the website to launch first and later support iOS and Android without duplicating business rules.

How long does classifieds marketplace development take?

Timeline depends on first-release scope, integrations, UX, security and content readiness. We define a delivery plan after discovery, separating the MVP from later extensions.

Do you have experience with agricultural marketplaces?

Yes. KILOGRAM is our documented agricultural and food trading platform with web, mobile, a shared API, listing flows and selected community and AI capabilities.

Are community features and private chat the same product module?

No. Public discussion, moderation and reactions have distinct visibility and security requirements from direct buyer–seller messages. They are scoped separately.

Can AI generate product photographs?

AI can produce illustrations, but they must not be passed off as photographs of the listed goods. We design labeling, validation, approval and fallback workflows.

Can the marketplace serve multiple businesses and countries?

Yes, with appropriate organization roles, location models, languages, publishing rules and integrations. Country-specific requirements are assessed independently.

Start a project conversation

Know the market you want to connect? Let's design the right platform.

A short description of your audience, listings and trading workflow is enough to begin. We'll help scope the first release and decide when mobile, community and AI make sense.

Discuss scope and request an estimate

No generic price promises and no unnecessary feature commitments.
