ChatGPT App Development Services

What's real:

• Your customers are already asking ChatGPT about your category. If you don't own that conversational context, you're invisible in 800 million weekly conversations.
• Intent-based discovery (no downloads). Could hit $40 billion in developer revenue if adoption mirrors App Store patterns.
• Seven partners launched October 6th: Booking.com, Zillow, Spotify, Canva, Coursera, Figma, Expedia. Eleven more coming soon: OpenTable, Target, DoorDash, Uber, Peloton. They're claiming categories while you read this.

What we don't know:

• How surfacing actually works. ChatGPT controls which apps appear. We optimize for intent capture, but the algorithm is opaque.
• If OpenAI will change everything. The SDK is 5 weeks old. We've seen this before with Alexa Skills and Apple Watch apps.

Our take: If you have all three qualifiers (see below), build now. Missing one? Wait and see.

✅ 1. Daily workflow that's faster through conversation

Works:

• Booking appointments (healthcare scheduling, restaurant reservations)
• Searching proprietary databases (legal case law, customer records)
• Placing orders (B2B procurement, supplier management)
• Checking status (shipment tracking, account balance)
• Finding candidates (recruiting, talent matching)

Doesn't work: Visual design, browsing, social features, anything requiring sustained engagement.

✅ 2. Proprietary data ChatGPT can't access

Works: Customer records, transaction history, proprietary databases worth $500K+ annually.

Doesn't work: Public information, generic aggregation, content ChatGPT already knows.

✅ 3. Open category or unique angle

Open: Healthcare scheduling, B2B procurement, legal research, financial planning, recruiting, corporate travel, home services.

Claimed: Travel (Booking.com), real estate (Zillow), music (Spotify), design (Canva), learning (Coursera).

Coming soon: OpenTable, Target, DoorDash, Uber, Peloton.

Missing one? Book the assessment to learn what needs to change.

It's early but this how we see this process:

Week 1: Analyze if your category is open, if competitors are building, if you should proceed.

Weeks 2-3: Design MCP architecture (works across ChatGPT, Claude, Gemini), audit your backend, identify blockers.

Weeks 4-14+: Build, integrate, test in Developer Mode.

Three service tiers:

• Intent Capture: Simple workflows, single backend
• Proprietary Data: Multi-source integration, authentication
• Enterprise: CRM/ERP connections, custom security

Q4 2025: Submit when marketplace opens. You've tested for 8 weeks. Competitors rush untested apps.

What you get: Full code ownership, MCP documentation, OAuth 2.0 authentication, platform expansion playbooks, 30 days support.

When can ChatGPT apps be published?‍

Submissions open Q4. Developer Mode is open now. You need 8 weeks to learn how users actually talk. Wait until Q4 and you're guessing.

What conversation data does our app access?‍

Your MCP server gets user prompt and relevant context. Your data never goes to OpenAI. You control what returns.

Can you guarantee app placement or surfacing?‍

No. ChatGPT controls surfacing. We optimize for intent capture. We guarantee MCP architecture that works across all platforms without rebuilding.

What if OpenAI changes the Apps SDK?‍

They will. MCP means you're not locked in. When Claude, Gemini, Microsoft launch apps, you deploy immediately.

Should we build ChatGPT apps internally or hire developers?‍

Internal if you have conversational AI expertise. Hire if you're learning. Mobile app skills don't transfer.

Which categories still have opportunity for ChatGPT app development?‍

Healthcare scheduling, B2B procurement, legal research, financial planning, recruiting, corporate travel, home services.

We're a 200-person software development company in Poznań, Poland. For 18 years, we've built data platforms and AI integrations for enterprise clients: complex API architectures, real-time data processing systems, conversational interfaces for internal tools.

The ChatGPT Apps SDK dropped just a few weeks ago. No one has a 2-year track record here. What we have: experience building the exact infrastructure ChatGPT apps require (MCP servers, authentication flows, multi-platform APIs), and weeks of obsessive analysis since October 6th.

We've turned down 14 of 30 ChatGPT projects because they shouldn't be built yet.

We're optimizing for apps that work, not project volume.

BUILD NOW ──────────────────────────────────────────
Test 8 weeks in Developer Mode
Publish refined app Q4 2025

WAIT UNTIL Q4 ──────────────────────────────────────
Competitors test while you wait
Rush untested app to market

DON'T BUILD ────────────────────────────────────────
Fix what's missing first:
- Workflow doesn't compress through conversation
- Launch partners claimed your category
- No proprietary data
- Backend not ready

If you wait until Q4, you're missing out. Competitors will have 8 weeks of testing data and trained ChatGPT's algorithms.

We help you decide in 45 minutes

1. Category analysis for your ChatGPT app
Is it open? Who's building now? What intent triggers can you own?

2. Technical readiness for OpenAI Apps SDK development
Is your backend ready? What integrations needed? What's the real timeline and cost?

3. Build / wait / don't build recommendation
Based on the data above, we tell you which and why.

You keep everything: Category analysis, competitive intel, technical assessment, cost estimate.
