Klaxon aggregates seismic, volcanic and weather alerts into a live map, helping responders and the public act faster. A $12 million Series A led by Acrew Capital gives the startup resources to scale its data pipelines, add AI‑driven impact scoring, and expand into emerging markets.
Klaxon’s Real‑Time Global Emergency Tracker Gains Momentum with $12 M Series A
![]()
Company: Klaxon (klaxon.live) – a SaaS platform that ingests, normalises and visualises real‑time natural‑hazard data from dozens of authoritative sources, then pushes alerts to web, mobile and API consumers.
Problem they solve
When a magnitude‑6 earthquake strikes off the coast of a small island, the local emergency office often receives the first tremor data minutes after the event, but the broader public may not see a reliable warning until hours later. The same lag exists for volcanic ash advisories, tsunami watches and severe storm warnings, especially in regions with fragmented monitoring networks. Existing services either focus on a single hazard type or provide static dashboards that are difficult to embed in local government portals.
Klaxon tackles three pain points:
- Data fragmentation – over 200 feeds (USGS, EMSC, JMA, Copernicus, regional seismological agencies) publish in different formats (CSV, XML, proprietary JSON). Klaxon’s ingestion engine normalises these streams into a single schema within seconds of receipt.
- Latency for downstream users – many public‑facing maps refresh only every 5–10 minutes. Klaxon’s push‑based API delivers alerts to subscribed endpoints in under 30 seconds, enabling SMS, push‑notification or radio‑broadcast integrations.
- Contextual relevance – an M4.2 quake near a sparsely populated area is less urgent than a similar event near a major city. Klaxon’s AI model scores each event on population exposure, infrastructure vulnerability and historical impact, producing a “risk index” that can be filtered by end‑users.
Funding and traction
In March 2026 Klaxon closed a $12 million Series A round. The round was led by Acrew Capital, with participation from Data Collective DCVC, SOSV’s IndieBio, and the United Nations‑backed Climate‑Tech Fund. Existing investors, including SOSV’s HAX accelerator, doubled down on the round, signalling confidence in the startup’s path to profitability.
The capital will be allocated as follows:
- Infrastructure scaling – expanding the Kubernetes‑based ingestion pipeline across three additional cloud regions (Asia‑Pacific, Africa, South America) to reduce geographic latency.
- AI risk scoring – hiring two data‑science teams to refine the exposure model, integrate satellite‑derived damage estimates, and open‑source the scoring algorithm on GitHub (klaxon‑risk‑engine).
- Product extensions – launching a white‑label dashboard for municipal emergency management (beta with the city of Port Blair, India) and a low‑cost API tier for NGOs operating in the Pacific Islands.
- Regulatory partnerships – formalising data‑sharing agreements with the International Seismological Centre and the World Meteorological Organization to ensure compliance with open‑data mandates.
Since its public launch in late 2024, Klaxon has logged more than 1.2 million unique map sessions and its API serves ≈ 250 k requests per day. Notable adopters include:
- The Pacific Disaster Center, which now pulls Klaxon’s tsunami alerts into its humanitarian‑aid workflow.
- Airlines in the Asia‑Pacific region that use the risk index to reroute flights pre‑emptively.
- A consortium of community radio stations in the Caribbean that broadcast real‑time alerts via a simple webhook.
Why it matters
The ability to act on a hazard within the first few minutes can be the difference between life and death, especially in low‑resource settings where traditional siren networks are unreliable. By aggregating disparate feeds, trimming latency, and adding a contextual risk layer, Klaxon provides a practical tool for both governments and private actors.
Moreover, the funding round reflects a broader investor appetite for infrastructure that sits at the intersection of climate resilience and data‑as‑a‑service. As extreme‑weather events become more frequent, platforms that can translate raw sensor data into actionable intelligence are likely to become core public‑utility components.
Looking ahead
Klaxon’s roadmap for the next 18 months includes:
- Multi‑hazard correlation – linking seismic events with subsequent landslides or tsunamis to generate composite alerts.
- Edge deployment – offering a lightweight Docker image that can run on local government servers with intermittent internet, ensuring continuity during outages.
- Open‑data dashboard – a public‑facing portal that visualises historical risk scores, enabling researchers to study hazard trends over time.
If the startup can deliver on these milestones, it will not only cement its position as the go‑to real‑time hazard platform but also set a benchmark for how open data can be turned into life‑saving services.
