Use Cases

Why integrate with Crunchbase

Common scenarios for SaaS companies building Crunchbase integrations for their customers.

Auto-enrich CRM records with firmographics

Give your users a zero-touch enrichment experience where typing a company name or domain populates HQ, industry, employee count, and funding stage from Crunchbase. Eliminates manual data entry and keeps account records analyst-verified.

Trigger sales plays on funding events

Let sales and RevOps teams detect fresh capital injections, acquisitions, and IPOs on their target accounts, then automatically re-score leads or launch outreach sequences. Turns your platform into a real-time buying-signal engine.

Power hyper-personalized outbound at scale

Feed funding round data (amount, lead investor, announcement date) into your AI email generator so users can send timely, contextual cold emails. Dramatically lifts reply rates without adding manual research overhead.

Build deal flow and competitor portfolio tracking

For VC and corp dev platforms, monitor investments and acquisitions against a user-defined competitive set to surface deals and exit opportunities. Users get an automated, always-current view of market activity.

Map executive and founder networks

Enable relationship-driven selling and recruiting by pulling a person's job history, education, and event appearances to build complete stakeholder profiles. Useful for ABM, warm intros, and candidate sourcing.

What You Can Build

Ship these features with Truto + Crunchbase

Concrete product features your team can ship faster by leveraging Truto’s Crunchbase integration instead of building from scratch.

Company autocomplete and lookup

Use Crunchbase autocomplete search so users can instantly match typed input to a company, person, or event and retrieve the canonical Crunchbase record.

Advanced prospecting query builder

Expose Crunchbase's search predicates in your UI so users can filter organizations by category, location, funding stage, or headcount without leaving your app.

Funding and acquisition activity feed

Poll funding rounds, IPOs, and acquisitions on a schedule to render a live feed of financial events on each account or watchlist inside your product.

Executive profile and career history view

Render a person's jobs, degrees, and event appearances as a stakeholder profile using Crunchbase people and card endpoints.

Relational card-based enrichment

Fetch specific relational subsets like founders, child organizations, investors, or event appearances via card endpoints to keep payloads lean and UI-friendly.

Diversity and category-based segmentation

Segment accounts using Crunchbase categories, category groups, and diversity spotlights to power supplier diversity programs or industry-focused campaigns.

Why Truto

Why use Truto’s MCP server for Crunchbase

Other MCP servers give you a static tool list for one app. Truto gives you a managed, multi-tenant MCP infrastructure across 800+ integrations.

Auto-generated, always up to date

Tools are dynamically generated from curated documentation — not hand-coded. As integrations evolve, tools stay current without manual maintenance.

Fine-grained access control

Scope each MCP server to read-only, write-only, specific methods, or tagged tool groups. Expose only what your AI agent needs — nothing more.

Multi-tenant by design

Each MCP server is scoped to a single connected account with its own credentials. The URL itself is the auth token — no shared secrets, no credential leaking across tenants.

Works with every MCP client

Standard JSON-RPC 2.0 protocol. Paste the URL into Claude, ChatGPT, Cursor, or any MCP-compatible agent framework — tools are discovered automatically.

Built-in auth, rate limits, and error handling

Tool calls execute through Truto’s proxy layer with automatic OAuth refresh, rate-limit handling, and normalized error responses. No raw API plumbing in your agent.

Expiring and auditable servers

Create time-limited MCP servers for contractors or automated workflows. Optional dual-auth requires both the URL and a Truto API token for high-security environments.

How It Works

From zero to integrated

Go live with Crunchbase in under an hour. No boilerplate, no maintenance burden.

Link your customer’s Crunchbase account

Use Truto’s frontend SDK to connect your customer’s Crunchbase account. We handle all OAuth and API key flows — you don’t need to create the OAuth app.

We handle authentication

Don’t spend time refreshing access tokens or figuring out secure storage. We handle it and inject credentials into every API request.

Call our API, we call Crunchbase

Truto’s Proxy API is a 1-to-1 mapping of the Crunchbase API. You call us, we call Crunchbase, and pass the response back in the same cycle.

Unified response format

Every response follows a single format across all integrations. We translate Crunchbase’s pagination into unified cursor-based pagination. Data is always in the result attribute.

FAQs

Common questions about Crunchbase on Truto

Authentication, rate limits, data freshness, and everything else you need to know before you integrate.

How does authentication work for Crunchbase through Truto?

Crunchbase uses API key authentication. Your end users provide their Crunchbase Enterprise or Data API key during the connection flow in Truto, and Truto securely stores and injects it into every request — you never handle credentials directly.

What Crunchbase entities can I read via Truto?

Truto exposes organizations, people, funding rounds, acquisitions, IPOs, investments, ownerships, events, event appearances, jobs, degrees, addresses, categories, category groups, locations, diversity spotlights, and principals — with both single-record fetches and search endpoints.

Can I fetch specific relationships without pulling the full entity payload?

Yes. Crunchbase's 'card' endpoints (e.g., organization cards, people cards, funding round cards) let you request scoped relational subsets like founders, investors, child organizations, or event appearances. This keeps payloads lean and rendering fast.

Does Truto support Crunchbase's advanced search predicates?

Yes. The search endpoints for organizations, people, funding rounds, acquisitions, and other entities pass through Crunchbase's predicate-based query model, so you can build complex filters (up to 25 predicates) on category, location, funding, dates, and more.

How do I keep data in sync and detect deletions?

Truto exposes Crunchbase's deleted entities endpoints so you can reconcile removals from your local cache. Combined with scheduled polling on search endpoints, you can maintain fresh, accurate data without missing hard deletes.

Can I write data back to Crunchbase?

No. The Crunchbase API is read-only — Truto supports fetching and searching data across all supported entities, but Crunchbase does not expose create, update, or delete operations for external applications.

Is there a way to inspect the full Crunchbase schema?

Yes. Truto exposes Crunchbase's metadata endpoints, including field definitions and the full OpenAPI spec in JSON or YAML, so your team can programmatically discover available fields and build type-safe mappings.
