On June 30, 2015, the company announced a $40 Million Series B led by Promus Ventures with participation from Bessemer Venture Partners and Jump Capital.
in order to help finance the first batches of Lemur satellites.
The first Lemur-2 were launched in September 2015 through the Polar Satellite Launch Vehicle-XL, making Spire the first US-based operator to launch from India.
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.

Facing increasing pressure to mass produce satellites and constrained by the limited space in its San Francisco office, Spire opened an office in Glasgow in February 2015, initially leveraging Clyde Space’s facilities, before opening its own full-fledged cleanroom for satellite manufacturing in December 2015.
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.
These facilities enabled Spire to quickly produce a first batch of four nanosatellites (launched in September) before manufacturing a full eight Lemur satellites ahead of an Atlas V launch in March 2016.
This launch saw Spire cross the line of 10 simultaneously operating satellites in June of that year, following deployment from the ISS.
Two additional launches were conducted that year, putting the total satellites sent to space by the company that year at sixteen, confirming its ability to industrialize the manufacturing process of its nanosatellites.

Concomitantly, Spire opened a second U.S campus in Boulder, Colorado in January 2016.
The company hired Dave Ector – the former program manager for NASA’s COSMIC satellites – and Alexander MacDonald - 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 GNSS Radio Occultation payload, enabling the company to constantly collect highly accurate data on local atmospheric properties which greatly enhance the forecasting abilities of weather models.
This program quickly enabled Spire to participate in the inaugural Commercial Weather Data Pilot program of the U.S National Oceanographic and Atmospheric Administration in September 2016.
Spire’s participation was confirmed and broadened in September 2018 for the second round of the CWDP program.
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.
Spire closed the year by completing a $70m Series C led by the Government of Luxembourg (through its national Luxembourg Future Fund), and opened its second European campus in the city, enabling the company’s access to regional talent and facilities.
 This round put the total amount of capital raised by Spire at $140.5m.

In early 2018, Spire participated in the first flight of Rocket Lab’s Electron rocket, and was selected for Arianespace’s Vega Proof of Concept, further broadening its launch portfolio.
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.

In 2019, the company formalized its first business unit as Spire Maritime, based in Luxembourg, and launched its 100th Lemur satellite on April 1st.
