AI-assisted business tools for data-driven operations.
Pick the question. Run the numbers. Leave with a memo. Pressure-test pricing, cash flow, ROI, staffing, and vendor calls. Every tool calculates from your inputs and shows the assumptions behind the answer.
Pro is $99/mo after a 14-day free trial - no card to start; add billing before day 15 to keep access.

See sample outputsUseful now. Built to grow.
Working calculators, forecasts, and drafts today; deeper integrations and provider-dependent AI layer in behind explicit approval gates, with trace logs on every run.
Numbers and drafts, not chatbot advice
You enter the numbers and context. BrainStack Studio returns a calculation, scorecard, or draft document with the assumptions shown.
Structured, reviewable runs
Every run shows inputs, calculation notes, recommendation, and review trail. External actions still need a human decision.
Useful before integrations
The live product works as calculators, planners, scorers, and generators today — value before any integration is switched on.
Founders & CEOs
Pricing, cash flow, break-even, hiring. Run the numbers on every decision that matters before you commit.
Open ToolsFinance & Ops Leaders
Ship shareable forecasts and scenario comparisons with full audit trails your board will trust.
Open Cash Flow ForecasterDepartment Heads
Workforce capacity, vendor evaluations, project health checks. Structured outputs for every operational call.
Open Workforce PlannerBuilt for the people who buy, evaluate, and use the outputs
Each paid path has a concrete first value, a named buyer question, and a reason to upgrade — not vague AI promises in place of working tools.
Founder / Operator
Which pricing, runway, hiring, and workflow decisions need structure before the next bet is made?
Paid plans save scenarios, preserve trace history, and turn one-off tool runs into a repeatable workflow.
Run Pricing OptimizerAgency Owner
Which client delivery, proposal, staffing, and margin workflows need repeatable artifacts instead of manual assembly?
Paid plans organize client work, exports, and reusable decision artifacts so delivery quality scales with the team.
Draft an RFP responseOps Leader
Where are handoffs, staffing, SOPs, project health, and vendor decisions slowing the workflow down?
Paid plans keep saved sessions, comparison exports, and repeatable workflow reviews available across teams.
Generate an SOPTechnical Evaluator (IT / Systems)
Can BSS produce deterministic outputs, clear traces, API controls, and implementation boundaries that hold up technically?
Pro adds API access, key-bound telemetry, JSON exports, and workflow chaining for serious evaluation.
See risk assessment exampleEconomic Buyer (Finance / Owner)
What does the team get for the subscription, what remains scoped, and how is value measured without exaggerated claims?
Pricing ties paid value to exports, saved history, API access, support, and sales-reviewed setup instead of broad automation promises.

CONDITIONAL REVIEW — pilot only after local inputs are verified
Use your actual territory, labor, and cash assumptions before making the go/no-go call. This sample shows where approval gates appear; it is not a market forecast.
Confidence

Break-even
Calculated from inputs
Approval gate: Requires owner or CFO sign-off when your configured threshold is exceeded
Refresh: Re-run with current labor, cost, and market inputs before approval
Export formats: CSV table and JSON trace follow paid-plan access
Reasoning Chain (abridged)
Illustrative trace from a market expansion analysis. Your runs use the same review structure with your data.
Run your own toolEvery business hits these questions
The decisions that keep operators up at night. BrainStack Studio gives you the math, the scenarios, and a reviewable path to move.
See What the Output Looks Like
Tool runs produce reviewable memos, tables, scores, recommendations, and trace notes. Here is the shape before you enter your own data.

Making decisions without data?
Pricing decisions made on gut feel instead of margin math
Cash flow surprises because nobody ran the 13-week forecast
Investment proposals that get rejected because the numbers are vague
Hiring decisions made without capacity data to back them up
BrainStack Studio replaces guesswork with structured answers. Here's how.
From question to defensible answer — in one focused sitting.
A guided path from operational complexity to a clear, measurable plan.
Discover
Pick the business question: pricing, cash runway, ROI, staffing, vendor risk, lead quality, or a draft operating document. No setup or import wizard required.
Run
Enter your own numbers and constraints. BrainStack Studio calculates the result, flags assumptions, and writes next-step recommendations.
Compare
Compare scenarios such as best/base/worst cases, break-even points, utilization gaps, or vendor scores before committing.
Decide
Save the result, export on paid plans, and bring the memo, scorecard, forecast, or draft to the owner who decides.
15 Calculators, Scorecards, and Generators. One Review Trail.
Real calculations, assumption checks, exportable trails. Every run produces a memo, forecast, scorecard, or draft your CFO, board, or operator can inspect.

Rigor you can verify, proof you can audit
Public proof is either an approved customer entry from the proof registry or a source-tagged product fact. Every tool run still shows the math, assumptions, and decision trail.
Deterministic by design
The calculators are pure functions: same inputs, same answer, every time. No hidden randomness, no model drift — re-run a decision next quarter and reproduce it exactly.
The math is shown, not hidden
Every run exposes the formula, the assumptions, and the decision trail. NPV, payback, break-even, CAC, and contribution margin use standard textbook formulas you can audit.
Public tool-run allowance
One free run per tool per day, no account needed. The free run produces a real memo — sign up free to save it, upgrade to export it.
Human review before action
BrainStack Studio supports the decision and keeps inputs, outputs, and notes attached for a teammate to review. These public tools never send emails, change policies, or move money.
The math is the proof.
Every figure on the /proof page was computed seconds ago by the same engines that power these tools. Re-run any of them with your own inputs and get the identical result.
Deterministic, auditable math
Every result is a pure function of your inputs. Same numbers in, same answer out — re-run it next quarter and reproduce it exactly. No hidden randomness, no model drift.
See it run live →Published formulas, standard citations
NPV, payback, break-even, and contribution margin use textbook definitions — cited to Brealey, Myers & Allen and Horngren. Check the math against any finance reference. That is the point.
Human review gates, not blind automation
Every run shows inputs, assumptions, and decision trail — attached for a teammate to review before any action. These tools never send emails, change policies, or move money on their own.

The methodology behind the numbers
These are the standard formulas the engines apply to your inputs. Check them against any finance reference — that is the point.
Net Present Value (NPV)
NPV = Σ Cₜ / (1 + r)ᵗ − C₀
Discounts each future cash flow Cₜ at rate r over period t, then subtracts the initial outlay C₀. Used in the ROI Calculator for multi-year business cases.
Reference: Brealey, Myers & Allen, Principles of Corporate Finance
Payback period
Payback = Initial cost ÷ Net cash inflow per period
How long until cumulative inflows recover the investment. Shown alongside NPV so a short payback never hides a negative NPV.
Reference: Standard capital-budgeting definition
Break-even point
Units = Fixed costs ÷ (Price − Variable cost)
The volume where contribution margin covers fixed costs. The denominator is the per-unit contribution margin.
Reference: CVP (cost-volume-profit) analysis, Horngren, Cost Accounting
Contribution margin
CM = Price − Variable cost per unit
What each sale contributes toward fixed costs and profit. Drives the Break-Even Analyzer and Pricing Optimizer.
Reference: Horngren, Cost Accounting: A Managerial Emphasis
CAC payback
Months = CAC ÷ (ARPA × Gross margin)
Months of gross-margin-adjusted revenue to recover the cost of acquiring a customer — a core SaaS efficiency check.
Reference: SaaS unit-economics convention (e.g. a16z / Bessemer metrics)
13-week cash runway
Endingₜ = Endingₜ₋₁ + Inflowₜ − Outflowₜ
A rolling weekly cash position from your opening balance and projected flows. Flags the exact week the balance turns dangerous.
Reference: Direct-method short-term cash forecasting
Formulas are applied to the numbers you enter. We do not ship default "X% savings" claims or industry benchmarks we cannot source.
