Tool library

Interactive tools for hardware decisions.

Use these tools to compare manufacturing options, estimate assembly effort, assess lifecycle impact, and test the commercial case before committing more time or money.

18 practical tools for common product decisions
18 guides explaining what the numbers mean in practice
04 core decision areas: manufacturing, sustainability, development, and commercial planning

Engineering and sustainability

Tools for product architecture, manufacturing, and lifecycle impact.

These tools help teams compare process routes, labour burden, footprint drivers, and lifecycle leverage before committing too early.

Manufacturing

Manufacturing Payoff Visualiser

Compare fixed setup cost and variable unit cost across 3D printing, CNC machining, vacuum casting, and injection moulding.

Break-even Cost curves Bridge production
Costing

Product Cost Estimator

Build a bottom-up COGS estimate using material, bought-in parts, labour, packaging, scrap, and overhead assumptions.

COGS Bottom-up costing Supplier prep
DFA

Assembly Time Estimator

Estimate concept-stage assembly effort using part count, handling complexity, join count, and quality checks.

Labour cost DFA Part count
Carbon

Carbon Footprint Estimator

Estimate concept-stage footprint using material, process, transport, and use-phase assumptions.

Embodied impact Use phase Comparison
Lifecycle

Product Lifecycle Explorer

Explore how lifetime, repairability, energy use, and end-of-life strategy shape lifecycle performance.

Durability Circularity Recovery

Concept and development

Tools for concept selection, process mapping, and delivery planning.

Use these to structure debate, prioritise the next stage of work, and decide what should be proven before scale-up.

Framework

Product Purpose Framework

Review ideas across human value, planetary impact, viability, and technical feasibility, then compare them against practical benchmarks.

Radar chart Ranking Sustainability
Selection

Pugh Concept Selector

Compare early concepts against weighted engineering criteria with a clear decision matrix.

Weighted scores Concept choice Trade-offs
Process

Product Design Process Map

Map development priorities based on stage, complexity, regulation, novelty, and launch pressure.

Gate planning Project flow Priorities
Production

Production Strategy Planner

Stage low-volume validation, bridge production, and scale-up planning in one route model.

Tooling timing Risk staging Scale-up
Prototype

Prototype Strategy Tool

Choose between 3D printing, CNC, vacuum casting, bridge tooling, and pilot injection based on what the next build must prove.

Prototype route Fidelity Learning speed

Commercial and market

Tools for hardware economics, channel design, and investor-facing signals.

These tools connect unit economics to launch route, business-case quality, and the metrics that matter outside the engineering team.

Economics

Launch Margin Planner

Model blended launch margin using route mix, hidden selling costs, overhead, and current COGS.

Route mix Break-even Hidden costs
Business case

Hardware Business Case Builder

Connect market size, cost structure, pricing, and operational assumptions in one working model.

Market funnel Payback Screening
Channels

Target COGS by Route to Market

Work backwards from RRP to see what COGS DTC, marketplace, and retailer routes can support.

DTC Marketplace Retail
KPIs

Investor Metrics and KPIs

Summarise monthly revenue, gross margin, CAC, runway, and payback signals for a hardware business.

Runway CAC Gross margin
Break-even

Break-even Calculator

Calculate the unit volume and revenue needed to recover fixed costs at the current contribution margin.

Contribution margin Volume target Fixed cost recovery

Founder planning and legal

Tools for cash, pre-launch budget, and supplier-ready conversations.

These tools help founders and product teams estimate the capital required before launch, manage runway pressure, and prepare for manufacturer discussions more cleanly.

Cashflow

Cashflow Projection Tool

Project twelve months of cash movement using opening cash, growth, payment delay, overhead, and upfront spend.

Runway Working capital Payment timing
Pre-launch budget

Startup Cost Planner

Estimate development, prototype, tooling, compliance, inventory, and launch costs before sales begin.

Budgeting Contingency Fundraising target
Legal prep

NDA Generator

Create a simple one-way or mutual confidentiality draft for early design, cost, and manufacturing conversations.

Confidentiality Supplier discussions Document prep
