See what an agent can do with Carta before you ever sign up. Pick a story: recorded sessions replay real probe-harness transcripts; commands tagged live-capable can re-run against the real endpoint from our edge, right now (▶ run live — the exact same request, live and recorded lines always labeled); the live MCP handshake runs real requests from our edge, right now — including, where the server allows it, one real read-only tool call (bring your own key for auth-gated servers); sandboxed self-drive sessions are designed and gated (docs/TRY-IT.md).

Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 43 stories with headroom

What would move Carta’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Automation depth — how much of the product can run unattendedDefine rules that trigger actions automatically on events

    nonemoves PA Scoreimpact 30

    Missing: rule/trigger definition mechanism, event subscription or webhook system, evidence of automated actions firing on events.

  2. Stakeholder experience — stories about stakeholder experience in this arenaI get my own portal showing my grants, vesting progress, strike price, and what my equity could be worth under different outcomes

    nonemoves PA Scoreimpact 30

    Missing: any documentation or screenshots of the employee equity dashboard/portal UI, vesting visualization, or outcome-based valuation tool.

  3. Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models

    nonemoves PA Scoreimpact 30

    Missing: any AI-training data usage policy, opt-out settings, or privacy documentation addressing this concern.

  4. Fundraising modeling — stories about fundraising modeling in this arenaModel a priced round — dilution, option pool top-up, SAFE conversion, pro-forma ownership — and share the scenario with counsel and investors

    nonemoves PA Scoreimpact 30

    The evidence pack covers Carta's developer/API platform (cap table data retrieval, OAuth, MCP plugins, data warehouse) but contains no documentation of a scenario-modeling tool for priced rounds, dilution, option pool top-ups, SAFE conversion modeling, or pro-forma ownership sharing with counsel/investors.

  5. Agenticness — how well agents can access and operate the productPoint an agent at llms.txt or agent-oriented docs

    nonemoves agent-readyimpact 30

    Direct probes show no llms.txt file (404) and no machine-readable docs or OpenAPI spec discoverable at expected paths, meaning there's no agent-oriented docs entrypoint for an AI agent to point at; the MCP setup guide is a separate integration path, not an llms.txt/agent-docs format.

  6. Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background

    nonemoves Built-in AIimpact 30

    Carta's docs describe API/OAuth access and an MCP integration for querying cap table and fund data via natural language (carta-docs-9, carta-docs-30, carta-docs-31), but there is no evidence of scheduling, triggers, webhooks, or any mechanism for autonomous background-running automations built on the platform.

  7. Agenticness — how well agents can access and operate the productUse an official CLI

    nonemoves agent-readyimpact 30

    Missing: any mention of a CLI, command-line tool, or terminal-based interface.

  8. Agenticness — how well agents can access and operate the productSubscribe to events via webhooks

    nonemoves agent-readyimpact 30

    No evidence in the pack mentions webhooks, event subscriptions, or push notifications anywhere in Carta's API platform docs; the documented capabilities are REST endpoints, OAuth flows, MCP/Claude plugins, and a data warehouse, none of which describe webhook subscription support.
