Marketplace Projects We Delivered

Platforms connecting real buyers and sellers.

Freelance

Freelance marketplace for the CIS region - 3,000 users at launch

  1. Challenge

    A startup wanted to build a specialized freelance marketplace for CIS-region clients and freelancers - a niche underserved by Upwork and Freelancer due to payment and language barriers.

  2. Solution

    Full marketplace: freelancer profiles, project listings, bidding system, escrow payments via Stripe Connect, review system, and dispute resolution. Launched in Russian with regional payment methods.

  3. Result

    3,000 registered users in the first 30 days of launch. 180 completed projects in month one. Payment success rate 99.1%. Ranked on page 1 of Google for key CIS freelance search terms within 3 months.

B2B

B2B equipment rental marketplace - $2.4M GMV in first year

  1. Challenge

    Construction and manufacturing companies renting equipment had no centralized platform - the market was fragmented across phone calls, email, and local brokers with zero transparency on pricing or availability.

  2. Solution

    B2B rental marketplace with equipment catalog, real-time availability calendar, rental quote flow, digital contract signing, and automated invoicing. Seller verification and equipment certification system.

  3. Result

    $2.4M GMV in the first 12 months. 85 verified equipment suppliers onboarded. Average booking cycle: 3 days (phone) → 4 hours (platform). Zero payment disputes due to escrow model.

Education

Tutoring marketplace - reached Google page 1 in 3 months

  1. Challenge

    A tutoring marketplace startup needed strong SEO from launch because they couldn't afford paid acquisition. Every tutor profile and subject page needed to rank individually for local search intent.

  2. Solution

    SEO-first marketplace architecture: dynamic tutor profile pages with Schema.org Person markup, subject category pages with structured FAQs, city-specific tutor search landing pages, and auto-generated sitemap.

  3. Result

    Page 1 Google rankings for 340 tutor + subject + city keyword combinations within 3 months. 1,200 organic monthly visitors by month 3. 400 active tutor-student sessions per month without paid ads.

Frequently Asked Questions

How much does marketplace development cost?

An MVP marketplace with buyer/seller dashboards and Stripe Connect payments starts at $15,000. A full growth platform with Elasticsearch and commission management starts at $35,000. An enterprise platform with mobile apps and fraud detection starts at $70,000.

How do you handle payments between buyers and sellers?

We use Stripe Connect, which allows automatic payment splitting between your platform (commission) and sellers (revenue). Funds can be held in escrow until delivery is confirmed, then released. This is the same model used by Airbnb, Uber, and Fiverr.

How long does marketplace development take?

An MVP marketplace takes 12–14 weeks. A full growth platform takes 16–22 weeks. An enterprise platform with mobile apps takes 24–36 weeks. Timelines depend on feature scope and third-party integrations.

Can sellers manage their own store within the marketplace?

Yes. Each seller gets a dedicated dashboard with listing management, order processing, payout history, analytics, and messaging - fully isolated from other sellers but managed centrally by your admin panel.

Do you build the mobile app alongside the marketplace?

Yes. We offer iOS and Android apps (React Native) alongside the web marketplace. Both buyer and seller apps can be included in Enterprise scope, or added to Growth as a separate module.
