Build ChatGPT Apps That Sell

Specializing exclusively in GPT SDK development, helping companies rapidly deploy Custom ChatGPT Apps, AI Sales Automation, and Next-Gen AI Chatbots designed for profit and scale.

Why Choose BuildGPT

Unlike traditional AI tools or plug-ins, GPT SDK allows you to:

Total AI Ownership

Unlike closed AI tools, the GPT SDK gives you full control over logic, memory, permissions, and branding — meaning your AI behaves exactly how you want, without vendor limitations.

Deep Business Integration

Connect your AI directly to live data sources, CRMs, ERPs, payment systems, and custom APIs, enabling intelligent automation from lead capture to transaction.

Automate Conversations into Conversions

Deploy private, white-labeled AI agents across web, mobile, and internal systems that sell, support, onboard, and qualify leads — automatically and 24/7.

Features That Make Selling Easier

Everything you need to turn conversations into conversions—from in-chat discovery to checkout.

Be First. Or Be Late.

AI is no longer a competitive edge — custom AI apps are the new baseline. Businesses that act now will dominate their niche before GPT-native competition floods the market.

Sales Enablement

Show real-time inventory, pricing, and product fit using Responses API with web search + file search—no brittle scrapers.

Voice Agents

Spin up voice agents with gpt-realtime (image input, SIP phone calling, remote MCP tools) for inbound/outbound.

Performance Reporting

Dashboards powered by datasets, automated graders, and prompt optimization—measure what moves revenue.

Agile our project management

If you’ve ever said “We should build our own AI assistant for our business” — you no longer have to imagine it. With the GPT SDK, you can finally own one that thinks, speaks, and sells exactly like your best team member — but works 24/7 without limits.

B2B SaaS Teams

Replace manual qualification with AI agents that book calls and push leads straight into your CRM.

E-Commerce Brands

Deploy AI shopping assistants that guide visitors, upsell products, and recover abandoned carts automatically.

Agencies & Platforms

White-label GPT SDK apps you can resell under your own brand to instantly expand your service offering.

Enterprise Teams

Build internal AI tools with memory, role permissions, and data governance that meet corporate compliance standards.

Our Customers Love Us

Here’s what some of our customers say about our platform.

“We replaced our entire SDR qualification process with a GPT SDK agent built by BuildChatgptApps. It now books 40% of our demos automatically — and our sales team is begging for more bots.”

Michael Torres

Founder, TrendHive E-Commerce

“Our AI shopping assistant now does the work of three support reps and increased checkout conversions by 27% in the first month. This isn’t a chatbot — it’s a revenue engine.”

Aisha Patel

COO, Ascend Digital Agency

“We now resell custom AI assistants as part of our service stack — white-labeled, fully automated, and hosted by BuildChatgptApps. It’s the highest-margin product we’ve ever launched.”
