Documented path
Worked on Gowalla's iPhone app with Scott Raymond, extracting a reusable networking stack that shipped as AFNetworking in 2011. Built a parallel reputation via technical writing (later NSHipster) and Cocoa open source.
Not documented in reviewed sources beyond early iOS/Cocoa engineering career associated with Gowalla.
Longtime Cocoa/Swift open-source author (AFNetworking, NSHipster lineage); AFNetworking officially deprecated 2023 in favor of Alamofire-style stacks.
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 Mattt Thompson 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?
Self-taught Ruby/iOS developer who shifted from design to programming during college. Created AFNetworking at Gowalla. Capable engineer and prolific OSS contributor, but no prodigy evidence or exceptional early cognitive achievement.
Where it was dropped
+1Tailwind
What money, family standing, network, or permission was already in place before the work began?
Parents are both musicians who play in the symphony and teach music. Middle-class Pittsburgh suburbs family. Supportive but no tech domain overlap; sister followed music path while Mattt gravitated to computers.
The shape of the track
+2Tailwind
What place, timing, institution, or peer group made the next step available?
Carnegie Mellon (Philosophy/Linguistics with CS minor). Gowalla iOS work with Scott Raymond extracted AFNetworking. Austin Ruby community and the iOS mobile app wave. Cold-called his way into dream job at Gowalla.
A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: High. 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.
This is an unchosen opening or condition in the record, not an estimate of how much luck caused the outcome.
Strongest documented signals: Early online platform, Direct domain exposure, Frontier geography.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Domain proximity, Prior reps, Scarce skill depth.
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 Mattt Thompson'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.
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.
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 Mattt Thompson'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.
Not documented in reviewed sources.
AFNetworking (2011) became the de facto iOS networking stack after Mattt and Scott Raymond extracted it from Gowalla work. Age relies partly on batch CSV birth year 1986 (age ~25 at first release). Later NSHipster and Alamofire-era influence cemented status; family background not documented in reviewed sources.
