◆ Builder's toolkit

Business tools.

Calculators and frameworks operators actually use — runway, pricing, freelance rates, and a one-page business model canvas.

§ Tool 01

Runway estimator

How many months can you survive at your current net burn?

Net burn / mo

Default-alive?
No

Default-alive companies reach profitability before they run out of cash. Rule of thumb: raise when you have at least 6 months of runway left. Below 3 months you have no leverage — investors smell it.

§ Tool 02

Freelance rate calculator

Reverse-engineer the hourly rate your target income actually requires.

Most freelancers undercharge because they divide salary by 52 × 40. Reality: you'll bill closer to 50% of your time. Overhead covers taxes, tools, healthcare, downtime, biz dev. Profit margin funds growth — not optional.

§ Tool 03

Pricing frameworks

Eight ways businesses price — when each one wins, and how it fails.

Cost-plus
Best for

Manufacturing, agencies billing time.

How

Take your cost, add a margin (e.g. 40%). Simple and defensible.

Watch out

Ignores what customers will actually pay. Leaves money on the table for great products.

Competitor-based
Best for

Commodity markets, new entrants.

How

Anchor to incumbents: match, undercut, or premium-position.

Watch out

Races to the bottom. Doesn't reflect your unique value.

Value-based
Best for

B2B SaaS, consulting, anything with measurable ROI.

How

Price as a fraction (typically 10–20%) of the value created for the customer.

Watch out

Hard to quantify value. Requires deep customer discovery.

Tiered (Good / Better / Best)
Best for

Software, subscriptions, services with feature variations.

How

Three tiers — most buyers pick the middle. Anchor with a premium tier.

Watch out

Too many tiers paralyze. Keep features per tier sharply differentiated.

Usage-based
Best for

APIs, infra, AI tokens, anything metered.

How

Pay per unit consumed. Aligns price with value delivered.

Watch out

Revenue is unpredictable. Customers fear surprise bills.

Freemium
Best for

Network-effect products, viral B2C/B2B tools.

How

Free forever for basic use, paid for power features, teams, or scale.

Watch out

Brutal economics unless conversion > 2–5% or virality is real.

Per-seat
Best for

Collaboration software, team productivity tools.

How

Charge per active user. Grows with customer's team.

Watch out

Discourages adoption — customers cap seats to control cost.

Charm pricing & anchoring
Best for

Consumer, e-commerce, plan pages.

How

$99 beats $100. Show a $499 tier so $99 looks like a deal.

Watch out

Tactic, not a strategy. Doesn't save a weak value prop.
