company mission
Across the four snapshots from 1999 to 2004, there is no visible company mission, belief statement, or theory of change to track. The available text shows branding, navigation, archive chrome, and in later captures a "Saltar Intro" prompt, but nothing that states what Alector thought it was building or why. That means the honest answer is simple: we do not have evidence of mission evolution here because we barely have mission evidence at all. What stayed stable is the absence of substance in the captured text. From 1999 through 2004, the snapshots do not expose any explicit statement about purpose, strategy, or underlying company belief. There is also no visible shift from one position to another. The evidence is thin enough that we should be careful not to overread the design. A splash page is not a theory. A company name is not a mission. The most defensible conclusion is that the archive snapshots provided are too sparse to show whether Alector's mission changed, stayed constant, or was simply hidden behind intro pages and missing assets.
