Merge Builds Tools With OpenAI Technology

Integration platform Merge is using OpenAI technology including GPT-6 Astra, ChatGPT, and Codex for product reviews, marketing, and business development planning. Its products support both customer-facing software and internal AI-powered work.

Its products include Merge Unified for customer-data integrations, Merge Agent Handler for secure tool access for AI agents, and Merge Gateway for model routing and cost controls. Merge for Workforce brings these capabilities inside companies to manage which models, tools, and business systems employees can access.

Inside the company, CEO and Co-founder Shensi Ding uses Codex to review product code, including work on a setup interface for configuring tool access in Merge for Workforce. Her colleagues use GPT-6 Astra for product testing and marketing. According to Ding, tool calls through Merge succeed 99.9% of the time, compared to public MCP servers, which are around 60%.

Merge also uses GPT-6 Astra to power an automated assistant for executive dinners. For a dinner in Dallas, the bot pulled potential guests from CRM records and Apollo, checked previous invitations and responses, prepared email outreach from Ding's inbox, maintained an attendee tracker, proposed a seating chart, and created calendar notes where sales and customer success could add context about each guest.

In October 2026, Merge reported that preparing guest lists and outreach and maintaining the attendee tracker went from dozens of hours across the company to about 30 minutes per event, measured over the preceding three months. The company ran 16 executive dinners in Q3, up from eight in Q2, and plans to host more than 30 in Q4.

Charlie Lynch on Merge's sales leadership team built reusable AI workflows for deal approvals, forecast updates, and next steps after renewal calls. The marketing team used GPT-6 Astra to clarify messaging for the Merge Gateway Evaluations launch, while the social media team uses GPT-6 Astra in ChatGPT to find posts the company should respond to.
