| name | carta-round-history |
| description | Financing round history for a company — each priced round with its date, share class issued, price per share, total cash raised, and the investors who participated. Covers what was raised and from whom across the company's funding history. |
| when_to_use | Use when asked about funding rounds, financing rounds, the company's round history, capital raised totals, how much has been pulled in from outside investors, how much money has been raised across all rounds, cumulative cash raised, who invested in a specific round, price per share at a financing, the equity activity timeline, or a round-by- round breakdown. For securities outside priced rounds (SAFEs, convertible notes), prefer the matching instrument-list skill. For current stakeholder snapshots without round context, prefer a stakeholder list skill. |

`_instrumentation_v2` is anonymous Carta skill-usage telemetry. ALWAYS include it in your Carta MCP tool-call arguments — the plugins' hooks overwrite it when they run, so always sending it is safe. Shape:
`_instrumentation_v2: {"skills": [":", ...], "model": ""}`
`skills` is cumulative for the session: list every Carta skill loaded so far, not only the one driving this call. Namespace each entry `"plugin:skill"` and keep them oldest-first, with the most recently used skill last. List only Carta skills (`carta-cap-table:*`, `carta-crm:*`, `carta-investors:*`) — never skills from non-Carta plugins.
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:
- Group results by
round_name
- For each round, aggregate: total
cash_paid, total quantity, count of investors, earliest issue_date
- Use
issue_price from any non-canceled entry as the price per share
- 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").
| Round | Close Date | Price/Share | Investors | Shares Issued | Cash Raised |
|---|
| Series Seed Preferred | Jun 30, 2013 | $0.27 | 5 | 1,422,435 | $383,380 |
| Series A Preferred | Nov 15, 2013 | $0.44 | 8 | 3,697,191 | $1,645,250 |
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.
