Documented path
French education (École Polytechnique, Paris Nanterre). MS at Columbia. Based in San Francisco.
Education: École Polytechnique — MS (2016-2020). Columbia University — MS Computer Science (2019-2020). Université Paris Nanterre — Bachelor's (2017-2018).

Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Tom Achache against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.
The marble itself
+2Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
Admitted to École Polytechnique (one of France's most elite grandes écoles) via the competitive MP concours. MS at Columbia. Published quantum computing research with IBM researchers. Led Perception at Chef Robotics deploying 50+ production robots. Strong academic and technical trajectory from elite French education system.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
French education (École Polytechnique, Paris Nanterre). No specific family background details available. École Polytechnique admission is merit-based through competitive exam, not requiring family wealth, but French grande école track often implies educated family background.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
École Polytechnique (France's top engineering school, competitive concours admission). Columbia University MS. SLAC National Accelerator Laboratory internship. Chef Robotics and Ambient.ai (YC W17) experience. YC W26 with Unisson. Elite institutional trajectory across France and US.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.
What moved through the conditions
Silence in a biography is not evidence that perseverance was absent.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Frontier geography, Exceptional peer / cofounder, Direct domain exposure.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Complementary team, Capital safety, Domain proximity.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Notable and widely recognized within the domain. The tier summarizes documented career recognition through the data cutoff—not Tom Achache's worth or future potential.
Question four · where did the leverage come from?
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.
One or more documented starting advantages plausibly enabled this lever.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
One or more documented starting advantages plausibly enabled this lever.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
One or more documented starting advantages plausibly enabled this lever.
A structural wave is external to the person, even when their position improved access to it.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Tom Achache's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Not documented.
