Documented path
Engineering-focused co-founder who partnered with Ivan Zhao in the early 2010s; sources describe him as in his early twenties when hired/partnered for Notion. The duo rebuilt Notion after a near-failure period and shipped the product that defined modern modular workspaces.
Not fully documented; partnered with Ivan Zhao in early twenties as Notion technical co-founder (~2013).
Co-founder and CTO of Notion; continues as core product/engineering leader of the multi-billion workspace company.
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 Simon Last 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
+1Tailwind
What capability, drive, or early skill is documented in the person rather than their surroundings?
University of Maryland CS student who joined Notion after Zhao found his visual programming portfolio on Twitter. Dropped out of UMD to work full-time. Capable engineer with interest in visual programming, but thin public biographical detail limits assessment.
Where it was dropped
0Neither way
What money, family standing, network, or permission was already in place before the work began?
Family background not publicly documented. No information available on parents' professions, wealth, or domain connections. Scored conservatively based on absence of evidence.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Ivan Zhao partnership was the defining cofounder relationship. SF startup scene and the Notion rebuild in Kyoto (cost arbitrage) shaped the early product. Zhao's mother provided a $150K emergency loan. Akshay Kothari later joined as third co-founder/COO.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Low. 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
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Exceptional peer / cofounder, Frontier geography, Early online platform.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Complementary team, Scarce skill depth, Structural wave / timing.
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.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Simon Last'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.
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.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.
One or more documented starting advantages plausibly enabled this lever.
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Simon Last'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 in reviewed sources.

Last is consistently described as Notion's technical co-founder from ~2013 (CSV birth 1990 → ~age 23). The pair nearly shut down, then rebuilt the product; advantage is complementary cofounder intensity and product craft rather than documented family capital. Public biographical detail is thinner than for Zhao.
