Custom GPTs retire December 11. First 3 moved for $750.

Connect your systems to ChatGPT and Claude

Connectors to HubSpot, QuickBooks, Microsoft 365, Slack or Drive, and skills for repeat work. Teams of 20 to 500, fixed fees.

What we build. Connectors to the systems you use, skills for the work you repeat.

Custom connectors (MCP)

An MCP server between the assistant and HubSpot, QuickBooks, Microsoft 365, Slack, Drive or a database. Fixed fee, quoted after a 15-minute call.

Department skill packs

Weekly reports, quotes, client recaps and proposals, written from your real examples. Fixed fee per skill, quoted after a 15-minute call.

Custom GPT migration

We move the GPTs worth keeping to private plugins and replace custom actions that do not carry over. First 3 custom GPTs migrated for $750, done in 5 days.

Half-built connectors and GPTs, finished

Skills, connectors or GPTs that half work: we audit them, fix what is unreliable and hand them back with notes.

How it works

  1. A 15-minute call, then one fixed fee

    We look at your real workflow and the systems behind it, then give you one fixed number instead of a range.

  2. Connectors built and tested on your prompts

    Each person signs in with OAuth, the connector reaches only what the job needs, and anything that sends or changes data waits for a person.

  3. Skills and connectors handed over with a record

    What it does, what it can touch and who maintains it. Your admins control who gets access in each assistant.

Good questions

Which teams are the plugins for?

Operations and department heads at US companies of roughly 20 to 500 people that already pay for ChatGPT Business or Enterprise, or Claude Team or Enterprise, and want the assistants to do their team’s actual work, with their own systems behind it.

What is a private plugin?

In ChatGPT, a plugin bundles skills (instructions and workflow guidance) with connected apps that link to other systems, and a company can keep it private or share it inside its workspace. Claude has the same building blocks: skills, connectors and plugins. We use “private plugin” for skills and connectors built for your company and shared only with the people who need them.

What is a connector, and why MCP?

A connector lets an assistant read from, or take actions in, another system, such as your CRM, ticketing or a database. We build them on MCP (Model Context Protocol), an open standard. ChatGPT, Claude, Perplexity and Grok all accept custom MCP connectors, so one well-built connector can serve several assistants. Each platform has its own admin setup and permissions.

Can you connect QuickBooks, HubSpot or our CRM to ChatGPT or Claude?

Yes, that is the most common job. If a ready-made app or connector already does what you need, we set it up and tell you so. If not, we build a custom MCP server for that system, scoped to the records and actions the work needs, and connect it to the assistants your team uses.

How do you keep a connector secure?

Each person signs in with OAuth, the connector can only reach what the job needs, and anything that sends, changes or deletes data waits for a person to approve it. We document what it can touch and who maintains it, and your admins control who gets access in each assistant.

Custom GPTs retire on December 11.

OpenAI’s standard retirement date for custom GPTs is December 11, 2026. We move the ones worth keeping to private plugins, OpenAI’s migration path, and replace custom actions with an available app or a custom MCP connector. First 3 custom GPTs migrated for $750, done in 5 days.

Prices, platforms and the deadline

We already started building skills or connectors. Can you finish it?

Yes. Send us what you have. We audit it, fix what is unreliable, finish what is missing, and hand it back with notes, at a fixed fee quoted after a 15-minute call.

Which assistants do you build for?

Mostly ChatGPT Business and Enterprise and Claude Team and Enterprise. We also connect Perplexity and Grok, which take custom MCP connectors, and can advise on Microsoft Copilot and Gemini, which have their own ways to share agents inside an organization. If a platform is a poor fit for the job, we will say so.

What’s happening to custom GPTs?

OpenAI retires custom GPTs on December 11, 2026. Its migration path turns each GPT into a private plugin: instructions become a skill and knowledge files become reference files. Custom actions do not transfer and may need a custom MCP server. That migration is our entry offer: the first 3 GPTs for $750, done in 5 days.

  • HubSpot
  • QuickBooks
  • Microsoft 365
  • Slack
  • Google Drive

What do the plugins and connectors cost?

Custom connectors and department skill packs are a fixed fee, quoted after a 15-minute call. Custom GPT migration is a fixed $750 for the first 3 GPTs, done in 5 days, and larger batches are a fixed fee from $2,500. Seat costs are billed by each vendor and are not included.
