The Founder Stack
A Switchy Space for the 1–3 person founding team that does everything.
Spinning this stack up creates a Switchy Space — your team chats together, @-mentions every model and MCP listed below with shared context, and that whole memory becomes its own MCP server inside Claude Code, Cursor, Claude Desktop, and ChatGPT for every teammate.
Heads up: this stack uses 4 MCPs. Pro is needed for unlimited MCP connections — Starter ships with 1.
The Switchy Space a founding team lives in for the first hundred days.
Sonnet 4.5 as the default for product/eng/copy work, GPT-4.1 for outbound
and long-form drafts, Gemini 2.5 Pro when you need to drop a 50-page PDF
(term sheet, RFP, competitor manual) in and get the summary back.
GitHub and Linear for the build side: "@github status of PR 12",
"@linear what's still open for this week". Gmail and Notion for the
go-to-market side: "@gmail summarise the last thread with that customer",
"@notion add this to the positioning doc."
One memory across every co-founder's Claude Code, Cursor, ChatGPT, and
Claude Desktop. When a third teammate joins, they walk into the room
with full context — no onboarding doc archaeology.
