Best Mobile App Marketing Agencies for Marketplace Apps
The Ranked List
1. SemNexus — Best for Marketplace Founders Who Need Product, ASO, and Growth Together
SemNexus has shipped several marketplace apps end-to-end including My Home Delivery, Trusted Services, and Boss App.

SemNexus can fix those alongside the marketing program.

Key services: ASO, Apple Search Ads, Meta, TikTok, supply-side recruiting funnels, retention strategy, AEO, and app development.

Why they made the list: Marketplace growth requires product and marketing moving together.

Final Thoughts
Most agencies know how to acquire users.
Far fewer understand that marketplace growth requires balancing two completely different audiences while maintaining geographic density, onboarding efficiency, and operational execution.
For founders who need supply acquisition, demand acquisition, ASO, retention, AEO, and marketplace product changes coordinated under one growth system, SemNexus remains the strongest option on this list.
