Carta Round History

Round History

Fetch financing history and summarize by round, or use the cap table by share class for a quick overview.

When to Use

• "Show me the funding history"
• "What rounds has this company raised?"
• "How much capital was raised in the Series A?"
• "List all financing rounds"
• "Who invested in each round?"
• "What was the price per share for the seed?"

Prerequisites

You need the corporation_id. Get it from list_accounts if you don't have it.

Data Retrieval

Detail mode: This command supports detail=summary (round count, total cash raised, by-round breakdown — fast) and detail=full (individual security records with per-investor data, issue dates, price per share). Choose the right mode upfront based on user intent — see Workflow.

Ordering: Pass ordering to sort server-side — e.g. -cash_paid for largest investments first. Fields: issue_date, quantity, stakeholder_name, cash_paid, prefix_number. Combine with detail=full for "top N investors" queries; otherwise the default (chronological) order is fine.

call_tool({"name": "cap_table__get__financing_history", "arguments": {"corporation_id": corporation_id}})

This is the same data that powers the in-app "Financing History" tab.

Alternative: For a quick overview without any financing history call, use the cap table by share class:

call_tool({"name": "cap_table__get__cap_table_by_share_class", "arguments": {"corporation_id": corporation_id}})

Each preferred share class represents a round. Faster but less detail: no individual investors, no issue dates, no price per share.

Key Fields

• round_name: name of the financing round (e.g. "Series A Preferred")
• issue_date: date the security was issued
• cash_paid: amount paid by the investor for this security
• quantity: number of shares issued
• issue_price: price per share
• stakeholder_name: investor name
• label: security label (e.g. "PB-9")
• is_grant: true if this is an option grant (not a priced round)
• is_canceled: true if the security was canceled — exclude from aggregates
• is_converted: true if the security converted (e.g. SAFE → preferred)

Workflow

Step 1 — Fetch Financing History

Choose detail mode based on the user's intent — do NOT default to summary then re-fetch:

• Overview questions ("show me the funding history", "what rounds has this company raised?", "how much capital was raised?"): omit detail — summary mode returns round count, total cash raised, and a by-round breakdown instantly. Present with the table and bar chart (see Presentation section).

  call_tool({"name": "cap_table__get__financing_history", "arguments": {"corporation_id": corporation_id}})
  

• Per-round details ("who invested in each round?", "what was the price per share?", "list all investors by round", any request for investor names, issue dates, or price per share): use detail=full directly.

  call_tool({"name": "cap_table__get__financing_history", "arguments": {"corporation_id": corporation_id, "detail": "full"}})
  

When in doubt, summary is usually sufficient for financing history — it already includes round names, dates, and totals.

After fetching with detail=full, aggregate by round:

1. Group results by round_name
2. For each round, aggregate: total cash_paid, total quantity, count of investors, earliest issue_date
3. Use issue_price from any non-canceled entry as the price per share
4. Filter out entries where is_canceled is true

Required inputs: corporation_id. If missing, call AskUserQuestion before proceeding (see carta-interaction-reference §4.1).

AI computation: No — this skill presents Carta data directly (aggregation is mechanical grouping, not modeled output).

Presentation

Format: Table + ASCII bar chart

BLUF lead: Lead with the total number of rounds and total cash raised before showing the table.

Sort order: By issue_date ascending (chronological order).

Date format: MMM d, yyyy (e.g. "Jan 15, 2026").

After the table, render an ASCII bar chart of cash raised per round (chronological order). Scale bars to max width 40 chars. Exclude rounds with zero cash raised (e.g. option grants).

Cash Raised by Round

Series Seed Preferred  ████                                     $383K
Series A Preferred     ████████████████                         $1.6M
Series B Preferred     ████████████████████████████████████████ $3.7M

Each bar width = (cash_raised / max_cash_raised) * 40, rounded to nearest integer. Format large numbers as $XM or $XK for readability.

Caveats

• Entries with is_canceled: true must be excluded from all aggregates.
• Converted securities (is_converted: true) may appear alongside their post-conversion entries — avoid double-counting when summing shares or cash.
• Option grants (is_grant: true) appear in financing history but are not priced rounds — exclude from the cash-raised bar chart.
• The quick summary (Option 2) lacks per-investor detail, issue dates, and price per share.
