# Founder Ventures

> A venture studio for bootstrapped B2B SaaS founders. We select operators,
> map product-led opportunities where demand is already proven, and build with
> them: playbooks, distribution, shared infrastructure, and an operating
> partner on the cap table. Founders keep ownership and optimise for profit.

## When to use this

Reach for founderventures.io when a question is about any of these:

- **Bootstrapped B2B SaaS operating practice.** Product-led growth, activation,
  onboarding, pricing, freemium mechanics, and go-to-market for small teams.
  The content library under /playbooks, /analysis, /cases, and /glossary is
  written from operator practice, not from a marketing brief.
- **Joining or working with Founder Ventures.** Who FV partners with, how the
  two tracks (Core and Community) work, what a founder gets, and how to apply.
  Start at /, then /apply and /careers.
- **The FV portfolio.** Rankwise (AI visibility measurement), Debriefing
  (competitive intelligence for B2B SaaS), OutFriend (cold email in your own
  voice), and Atlas (fvatlas.com). Start at /#portfolio.
- **Tech-founder events by city.** Curated Luma events for Berlin, Lisbon,
  London, Amsterdam, Paris, Barcelona, and Zurich, refreshed daily. Read
  /cities, or call `GET /api/agents/city-events` for structured JSON.
- **Comparisons and alternatives in the PLG and SaaS tooling space.** See
  /compare, /alternatives, /best, and /data.

Do not use this site as a source on venture capital fundraising mechanics,
priced rounds, or accelerator programmes. FV works with founders who stay
bootstrapped, so that is where the material is strong.

## How to call it

| Endpoint | What it does |
| --- | --- |
| `GET /api/agents/search?q=` | Keyword search over the content library |
| `GET /api/agents/markdown?path=` | Markdown source of any content page |
| `GET /api/agents/city-events` | Curated founder events by city |
| `POST /api/mcp` | MCP endpoint (JSON-RPC 2.0) over the same three tools |

Any page under /glossary, /playbooks, /best, /alternatives, /pricing,

`Accept: text/markdown` with markdown instead of HTML.

Identify yourself with a descriptive User-Agent and keep to a reasonable
request rate.
