No birth time on record, so houses and the rising sign are not shown.
Note on this rating: Date and birthplace confirmed independently via Wikidata (P569/P19, precision to the day) and English Wikipedia. No reliable birth time is on public record, so none is asserted here.
This page compares Sun, Mercury, Venus and Mars, the four placements a birth date alone can place. Moon, Ascendant and Midheaven are left out here by design, not by omission, so nothing on this page is scored against a birth time it cannot trust.

The overlap
Two charts, laid over each other
Bill Gates and Paul Allen's Sun, Mercury, Venus and Mars are drawn here, the four placements a birth date alone can place with no birth time required. This is a complete chart of what is known, not a partial chart of what is not.

Why they click
The tightest contact between these two charts is Gates's Mercury quincunx Allen's Mars, eight hundredths of a degree from exact. Mercury to Mars is not one of the five pairings the engine tracks, so that near-perfect angle contributes nothing to any category. What carries the score is a Sun square Sun just under four degrees wide, which reads 75.
Why they clash
Communication and friction both return 30. Neither the two Mercuries nor the two Marses make an angle, so there is nothing on either axis to measure. Values reads 44 and attraction 36, both on trines wide enough to keep them near the bottom of the range. Six contacts, and a single hard aspect among them.
What each system says
Twelve systems, two people
The Suns are 86.2° apart, close enough to feed the identity category above.
Goat and Dragon are in neither the trines nor the clashes.
A second tradition
Guna Milan (Ashtakoot)
Guna Milan is the compatibility method used in Vedic matchmaking, traditionally consulted before an arranged marriage. It scores eight factors between two Moon placements on a 36-point scale, shown here as what this one tradition reads: not a verdict, and not averaged with the Western reading above, which may disagree.
Guna Milan needs an exact birth time for both people. The Moon changes nakshatra roughly once a day, so an estimated time can place the whole reading in the wrong one, and at least one birth time here isn't exact.

Frequently asked
Are Bill Gates and Paul Allen astrologically compatible?
Their charts make 6 cross-aspects, the tightest at 0.08° and 1.27°. Astrology does not score a relationship out of a hundred, and the number on this page counts how much contact two charts make, not how well two people do.
Why isn't there a house ring on the chart above?
At least one of Bill Gates and Paul Allen doesn't have a curated, non-estimated birth time, so a house placement would be a guess. This page only shows what a birth date alone can place.
What does quincunx mean between two charts?
A quincunx puts two placements at an awkward angle with no easy geometric relation, an adjustment rather than a flow or a clash. Bill Gates and Paul Allen have 2 quincunx contacts between them, more than any other type.
