Your details

Every pair of founders is read four ways. Refusal pairs are shown above the score because practitioners refuse them outright; the composite ranks the rest from Aligned to Adverse.

In brief

Two to six founders read pair by pair: refusal pairs, the composite, the four directions and roles.

How to use: fill in Business name (optional), Founder 1 name, Founder 1 date of birth, Founder 2 name, Founder 2 date of birth, then press the button.

How it works

Each founder's Origin and Master numbers come from the date of birth. Every pair is read in four directions on the friendship table and given a composite from -10 to +10, the Origin pair counted twice. Refusal pairs are shown above the score and never folded into it; the weakest pair sets the verdict.

Partner disputes rarely start over money. They start over who decides, and the numbers name that friction before the first invoice.

How this calculator works

  • R-REFUSAL Refusal pairs on Origin numbers are shown first and never folded into the score.
  • R-COMPOSITE 2 x (Origin A to Origin B) + (Master A to Master B) + (Origin A to Master B) + (Origin B to Master A); friend +1, neutral 0, opposed -1.
  • R-BANDS +6 to +10 Aligned, +2 to +5 Workable, -1 to +1 Mixed, -5 to -2 Strained, -10 to -6 Adverse.
  • R-GROUP The weakest pair governs the group verdict. With three or more founders practitioners recommend a company name digit of 5.
  • R-LADDER Strained and Adverse pairs get the remedy ladder: re-assign roles, add a compatible third partner, recruit a missing number, individual name correction, rename or a parallel entity, exit.

Not what this tells you. A Strained pair is a role-split instruction, not a verdict on the friendship. Many strained pairs run well once the decision rights are written down.

The reason

The composite doubles the Origin-to-Origin reading and adds Master to Master and each Origin number to the other's Master number, giving a range from minus 10 to plus 10. Nine Origin-number pairs are refused by practitioners outright (1-8, 2-8, 2-9, 2-7, 3-6, 4-8, 4-9, 4-4, 8-8) and five are contested (3-4, 7-8, 2-4, 2-6, 6-9).

Where the schools disagree

  • The 9 by 9 grade grid published by the source disagreed with its own directional table in four cells; this site derives the grid from the table so the two never conflict.

Questions

Do I need the founders' names?

No. Dates of birth are enough; names only label the rows.

What is a refusal pair?

An Origin-number pair practitioners refuse for business partnership regardless of the other numbers, such as 1 and 8 or 4 and 8. It sits above the score.

What is a contested pair?

A pair some practitioners refuse and others allow, such as 3 and 4. Shown as a caution, not a block.

Can a bad pair be fixed?

The ladder starts with roles. Most strained pairs settle once the 1 leads, the 2 runs the back office and the 8 runs production, with nobody sharing a chair.
