STX Next Launches ChatGPT App Development Services as $40B Market Opens to Developers

STX Next launches specialized ChatGPT app development services as OpenAI's Apps SDK opens to 800 million weekly users

Poznań, Wielkopolskie , Oct. 14, 2025 (GLOBE NEWSWIRE) -- STX Next today launched specialized ChatGPT app development services following OpenAI's October 6th release of the Apps SDK to developers. The agency's market analysis suggests ChatGPT apps could generate up to $40 billion in annual developer revenue if adoption mirrors early App Store patterns

ChatGPT's 800 million weekly active users provide developers with immediate distribution 133 times larger than the iPhone's estimated 6 million users when the App Store launched in July 2008.

"We've already received inquiries from companies since the SDK opened," says Łukasz Koczwara, CTO at STX Next. "The early pattern we're seeing is companies approaching ChatGPT app development like mobile app development when conversational interfaces require different architecture."

What Launch Partners Reveal About ChatGPT App Success

STX Next analyzed the seven launch partners OpenAI selected—Booking.com, Zillow, Spotify, Canva, Coursera, Figma, and Expedia—to identify patterns in successful ChatGPT app development:

Intent-based surfacing – Apps appear when contextually relevant (Spotify surfaces when users mention needing a playlist)
Proprietary data integration – Apps deliver personalized results using backend systems (Zillow shows listings matching conversation context)
Filtered decision-making – Apps present curated options rather than comprehensive results (Booking.com shows three hotels, not 50)

"These patterns inform how we approach ChatGPT app development for clients," says Łukasz.

Industries Suited for ChatGPT App Development

Based on launch partner analysis, STX Next identified industries with characteristics suited to ChatGPT apps:

Legal services, healthcare scheduling, B2B procurement, financial planning, recruiting, home services, and corporate travel management share attributes visible in OpenAI's partner selection: high transaction frequency, proprietary data that enables personalization, and workflows that simplify through conversation.

ChatGPT App Development Services: Model Context Protocol Architecture

STX Next's ChatGPT app development services include three tiers based on integration complexity:

Intent Capture Apps (4-8 weeks) – Natural language interpretation, single backend integration
Proprietary Data Apps (8-14 weeks) – Multi-source integration, user authentication systems
Enterprise Integration Apps (14+ weeks) – CRM/ERP connections, custom security protocols

All ChatGPT app development projects use Model Context Protocol (MCP) architecture—the open standard underlying OpenAI's Apps SDK. MCP-compatible apps deploy across ChatGPT and future AI platforms without platform-specific rebuilding.

"Model Context Protocol is essential for ChatGPT app development," says Łukasz. "Building MCP-native means companies deploy to ChatGPT today, Claude or Gemini tomorrow, using the same codebase."

Key Considerations for ChatGPT App Development

Companies evaluating ChatGPT app development should consider:

Whether their app delivers value through conversation versus visual interfaces
If they have proprietary data that enables personalized responses
Whether their workflow compresses or expands in conversational format
If their architecture supports Model Context Protocol for multi-platform deployment
