SkyAlert is a disaster-prevention tech that has made a business of 'handing people seconds to flee before the shaking' in earthquake-prone Mexico. Founded in 2011 by Álvaro Velasco and Alejandro Cantú, its own network of over 120 internet-connected sensors covers about 80% of Mexico's earthquake-prone regions (including the Pacific coast). When sensors catch the initial tremor, alerts fly via an app, home/business devices and social media, giving people seconds to a minute to leave homes, schools and offices. As the official earthquake-alert system (SAS/loudspeakers) repeatedly misfired or failed, after a major 2017 quake that killed over 460 people, its users doubled to 5.8 million and it became one of the country's most-downloaded apps. One user says that in the 2019 quake 'SkyAlert sounded seconds before the city's alert, and I could leave the building sooner.' It earns revenue from freemium (a paid tier at 59 pesos/year) and devices for buildings/businesses.

SkyAlert: Handing people seconds to flee before the shaking. The letter is B; certainty is medium. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q3; estimate based on public information.)
Main narrative
One person’s story (N1)
+ A single story
Alejandra Vera Izquierdo survived the 7.1 quake in 2017 but, angry that the city's alert—which could have let her flee with more time—was useless, installed SkyAlert (distrust of the official alert). In the 2019 quake she says 'SkyAlert sounded seconds before the city's alert, and I could leave the building sooner.' The benefit appears as the collective of millions in earthquake-prone Mexico who gained time to flee through early warning that fills the official system's gaps.

A second look
The plus is life safety through early warning in an earthquake-prone country (People), backed by over 5.8 million users, a 120-plus sensor network, real utility filling the gaps of the official system, and independent reporting from Rest of World/Reuters/WSJ. Caveats: a commercial model of freemium plus expensive devices ($2,000/year) partly paywalls safety (a question of equity); a 2014 false-alarm history; and Mexico City's government has tried to restrict private-company alerts citing 'over-alerting/panic/eroded trust,' making alert reliability a point of contention.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
Terms: Narrative Value = an assessment (A–G) of the distance between the story an organization tells and its reality / Ceiling meter = a visualization of the reachable upper bound / Watching = unconfirmed matters not counted / Protected stakeholders = people, animals, nature, and future generations. | Generated by: AI | As of: 2026-Q3 | Back to top
