Sieve

List all documents in a deal's data room.

Shows what files and content have been uploaded for a deal, along with their processing status.

Args: deal_id: The deal ID (from sieve_deals or sieve_dataroom_add).

Add a document to a deal's data room. Creates the deal if needed.

This is the primary way to get documents into Sieve for screening. Upload a pitch deck, financials, or any document -- then call sieve_screen to analyze everything in the data room.

Provide company_name to create a new deal (or find existing), or deal_id to add to an existing deal.

Provide exactly one content source: file_path (local file), text (raw text/markdown), or url (fetch from URL).

Args: title: Document title (e.g. "Pitch Deck Q1 2026"). company_name: Company name -- creates deal if new, finds existing if not. deal_id: Add to an existing deal (from sieve_deals or previous sieve_dataroom_add). website_url: Company website URL (used when creating a new deal). document_type: Type: 'pitch_deck', 'financials', 'legal', or 'other'. file_path: Path to a local file (PDF, DOCX, XLSX). The tool reads and uploads it. text: Raw text or markdown content (alternative to file). url: URL to fetch document from (alternative to file).

List deals in your Sieve pipeline.

Search by company name or list all deals. Returns deal metadata including Sieve scores for screened deals.

Args: search: Search by company name (partial match). Empty returns all. limit: Maximum results to return (1-100, default 20).

Get or generate an investment memo for a deal.

If generate=false (default), retrieves the existing memo. If generate=true, creates a new memo (~15-30 seconds). Requires a completed screen.

Args: deal_id: The deal ID (from sieve_deals or sieve_screen). generate: Set to true to generate a new memo. memo_type: 'internal' (IC-facing, full risks) or 'external' (founder-facing). Default: internal.

Get the full results of a completed Sieve analysis.

Returns the Sieve Score (0-140), meeting decision (Take Meeting/Pass/ Need More Info), executive summary, key strengths, and key concerns.

Args: deal_id: The deal ID returned by sieve_screen. sections: Comma-separated filter (e.g. 'summary,strengths,concerns'). Options: summary, profiles, findings, questions, strengths, concerns. Empty returns everything. Score and decision are always included.

Run a Sieve IMPACT-X Quick Screen on a startup.

Analyzes the company across 7 dimensions (Innovators, Market, Product, Advantage, Commerce, Traction, X-Factor) and returns an analysis ID. Takes 2-5 minutes to complete. Upserts -- if the company was previously screened, returns the existing deal (set confirm=true to re-screen).

Two ways to use:

• v3 (recommended): First add documents with sieve_dataroom_add, then call sieve_screen(deal_id=...) to analyze everything in the data room.

• v2 (legacy): Call sieve_screen(company_name=..., website_url=...) directly. At least one of website_url or pitch_deck_text is required in this mode.

Args: company_name: Name of the startup to screen (v2 flow, or to create new deal). deal_id: Screen an existing deal by ID (v3 flow -- use after sieve_dataroom_add). website_url: Company website URL (v2 flow). pitch_deck_text: Extracted pitch deck text (v2 flow). description: Brief company description (optional). confirm: Set to true to re-screen an existing deal.

Check the progress of a Sieve analysis.

Returns which IMPACT-X dimensions are complete with their scores, overall progress percentage, and current phase.

Args: deal_id: The deal ID returned by sieve_screen.
