[7] The company has offices in San Francisco, Boulder, Washington, D.C., Glasgow, Luxembourg, Munich, Singapore, and Cambridge (Ontario).

[13] A year after signing with NanoRacks, on November 19, 2013, both ArduSat-1 and ArduSat-X (1U CubeSats) were successfully released from the Kibo Experiment Module of the International Space Station and quickly started transmitting data to Spire servers.

[15][16] On the basis of this early success, Spire announced in July a follow-up $25M Series A funding round led by RRE Ventures and backed by Emerge, Mitsui & Co.

[21] This launch inaugurated the Spire tradition to leave the naming of each satellite to employees, with the first 3 Lemurs christened respectively Joel, Peter and Jeroen after the company's co-founders.

[22] The city was chosen to leverage the local know-how of what is widely considered the leading European ecosystem in small satellite production and establish a first foothold in Europe.

The company hired Dave Ector[25] – the former program manager for NASA’s COSMIC satellites – and Alexander MacDonald[26] – former director of NOAA’s Earth System Research Laboratory – and started drawing on the resources of the local weather ecosystem (powered by the University of Colorado Boulder) to kickstart its weather program in the city.

To this effect, the team started working on Spire's own Global Navigation Satellite System Radio Occultation (GNSS-RO) payload, enabling the company to constantly collect highly accurate data on local atmospheric properties which greatly enhance the forecasting abilities of weather models.

[29] This program aims to enable weather-focused administrations to procure data (largely obtained from Radio Occultation profiles) created by private entities in order to improve the precision of the publicly available weather models.

Over 2017, the company launched 6 missions, yielding an additional 36 operated satellites despite the critical failure of a Soyuz vehicle carrying 10 Lemurs in November.

It participated in a total of 7 launch missions – yielding 28 new operated satellites – and developed its own ADS-B payload able to track the movement of equipped airplanes across areas that conventional ground radars can not cover, and that is quickly becoming a standard following the MH370 disappearance.

[37] Due to missing projected revenue targets and rising losses, Spire's market value started falling after the first quarterly report.

This data is valuable for use in illegal fishing, trade monitoring, maritime domain awareness, insurance, asset tracking, search and rescue, and prevention of piracy, among others.

This data is getting increasingly regarded as the new standard for modern aviation as it enables air controllers and companies to constantly monitor aircraft across isolated areas and oceans which ground-based radars are not able to cover.

[45] In 2020, Spire announced its intention to add intersatellite links to its satellites, allowing for lower latency between data collection and delivery to a gateway site.
