Tools 23 found in our last check

• get_context

  Returns the universal context-setting primer for Hemrock models, plus an optional template-specific addendum. Always run this first before any other prompts.

• get_prompts

  Returns task-specific Layer 2 prompts for a given template and task type. These are ready-to-use prompts for common modeling tasks.

• get_checks

  Returns Layer 3 sanity-check and validation prompts — the 'where AI gets financial modeling wrong' guidance. Use these to audit AI-generated work or catch common modeling errors.

• get_best_practices

  Returns Hemrock's financial modeling best practices and design principles for a given topic. Useful as background context for AI interactions.

• list_concepts

  Lists Hemrock financial-modeling concept docs — the methodology behind the math (exit waterfalls, anti-dilution, convertibles, cohorts, circular references, unit economics, and more). Returns a compact index of slugs, titles, and descriptions. Optionally filter by template_name…

• get_concept

  Returns the full text of a single Hemrock concept doc by slug. Use this to learn how a financial-modeling calculation actually works before building or auditing it. Get valid slugs from list_concepts.

• list_models

  Lists the hosted Hemrock calculation engines (cap table, exit waterfall, fund economics, and the free unit economics, SaaS forecast and ecommerce forecast models), what each computes, and its price and checkout link. Free and needs no sign-in, so call it when the user asks what…

• get_access

  Returns public access terms for an engine: product, annual price, billing period, annual allowance, and a customer checkout URL. This is informational and does not purchase or confirm account-specific access; use get_account_access for the authenticated account.

• get_account_access

  Returns whether this connection is signed in, its annual product access and remaining calculations. Does not consume allowance. Call it before a compute tool if you are unsure the user can run one. If the result contains action_required (not signed in, no purchase, allowance use…

• get_account_usage

  Returns signed-in usage history and endpoint/source breakdown. Does not consume allowance. If the result contains action_required (not signed in, no purchase, allowance used), relay it to the user with its links and offer to retry. Never skip the calculation silently.

• cap_table_compute

  Use whenever the user asks who owns what after a financing: founder splits, option pools, priced rounds, SAFEs and convertible notes converting, warrants, pro-rata, or dilution across several rounds. Takes the financing events in order and returns fully diluted ownership after e…

• exit_waterfall_compute

  Use whenever the user asks what each holder gets at an exit, acquisition or liquidation: liquidation preferences, participating vs non-participating preferred, participation caps, seniority, whether a series converts, options and warrants in or out of the money. Takes the cap st…

• fund_economics_compute

  Use whenever the user asks how a venture fund's terms play out: fund size, management fees and step-downs, carry, investment period, recycling, reserves, deployment pace, and resulting net returns to LPs. Takes fund inputs (start from the defaults and change only what the user s…

• unit_economics_compute

  Use when the user asks what a customer is worth or whether acquisition pays back: lifetime value, LTV to CAC, CAC payback, gross margin per customer, for recurring (subscription), one-time and transaction (repeat purchase) revenue in any mix. Takes up to three revenue lines and…

• saas_forecast_compute

  Use when the user wants a SaaS or subscription revenue forecast: subscribers, MRR and ARR, new, renewed, churned and reactivated MRR, billings and deferred revenue under annual or multi-month contracts and billing, marketing spend, LTV to CAC and CAC payback. Takes new subscribe…

• ecommerce_forecast_compute

  Use when the user wants an ecommerce or DTC forecast built on customer cohorts: each month's new customers become a cohort that reorders along a retention curve, and the forecast adds the cohorts up into orders, revenue, cost of sales, marketing spend, operating income, contribu…

• list_saved_models

  Lists the cap tables, exit waterfalls, fund models and unit economics, SaaS and ecommerce forecasts saved to the user's Hemrock account, plus fund models others have shared with them, newest first. Each has its kind, id, name, the user's role (owner, editor, viewer) and a url th…

• get_saved_model

  Returns a saved model's contents in the shape the compute tools take: a cap table's events and options, a waterfall's model and saved exit, a fund's inputs, the features switched on, and featuresSavedButOff (configured but switched off), or a forecast's inputs. Free: uses no cal…

• run_saved_model

  Calculates a saved model as it stands, with the same engine as the browser builder: ownership after every event for a cap table, proceeds by holder for a waterfall (at the saved exit, or up to 10 exitValuations you pass), a fund's lifetime totals plus the fund by year (granulari…

• update_saved_model

  Saves a change to a model in the user's account; the browser builder shows it the next time it opens. Send only the fields that change. Owners can change anything; invited editors of a fund model can change its inputs while the owner has access; viewers can't change anything. Te…

• create_saved_model

  Saves a new model to the user's account so they can open it in the browser builder and keep working on it. A fund or a forecast (unit-economics, saas-forecasting, ecommerce-forecasting) starts from Hemrock's defaults with your inputs merged on; a cap table needs events; a waterf…

• check_in

  Reports what's worth knowing today about the models saved to the user's Hemrock account: for each of the ten most recently edited cap tables, exit waterfalls and fund models, notes where a number has crossed a line worth a look (a thin option pool, unconverted SAFEs, preferences…

• request_review

  Returns how to get a person on the user's model: a one-hour working session with the person who built Hemrock's models (also the way to get a model or workflow built with AI reviewed), custom model work, or fractional CFO for venture funds. Each comes with its live price and boo…
