Signatech was established as a constructor and team operator active across European junior formulae before turning its attention to sports car racing. The team won the FIA European Formula Three Cup in 1999 with Benoît Tréluyer and followed that with the French Formula Three Championship in 2000 through Jonathan Cochet, who also claimed the European Cup, Masters of Formula 3, and Korea Super Prix that same year.
In 2003, Signatech won the inaugural Formula Renault V6 Eurocup team championship with Tristan Gommendy and Kosuke Matsuura. The same year, Nicolas Lapierre and Fabio Carbone delivered a one-two finish at the Macau Grand Prix for the team. Edoardo Mortara and Jean-Karl Vernay repeated that Macau feat in 2009. Mortara and Marco Wittmann then dominated the 2010 F3 Euro Series, finishing first and second in the standings and winning eight races between them. After the 2012 season Signatech withdrew from Formula 3 entirely to concentrate on sports car racing.
Signatech entered the European Le Mans Series in the LMP1 category in 2009 and finished second in LMP2 at the 24 Hours of Le Mans in 2011 in cooperation with the Nissan GT Academy programme. In 2012 the team raced a Nissan-powered Oreca 03 at Le Mans, finishing tenth overall.
The decisive turn came in 2013 when Alpine partnered with Signatech to run an LMP2 entry in the European Le Mans Series with Pierre Ragues and Nelson Panciatici. The team won both the LMP2 Teams and Drivers championships that year. Rejoining the FIA World Endurance Championship in 2015, Signatech Alpine went on to claim the WEC LMP2 championship in 2016 and again in the 2018–19 super-season, establishing the partnership as the premier French LMP2 operation of its era.
In 2020, Signatech returned to the European Le Mans Series under a separate banner, the Richard Mille Racing Team, with an initially planned all-female driver lineup of Tatiana Calderón, Katherine Legge, and Sophia Flörsch. Legge's injury forced André Negrão to cover the opening rounds before Beitske Visser joined for the remainder of the season. The all-female lineup of Calderón, Visser, and Flörsch then competed in the LMP2 class of the 2021 FIA World Endurance Championship under the same identity.
For the 2021 WEC season Signatech partnered again with Alpine to field a grandfathered Rebellion R13 in the Le Mans Hypercar class, finishing third overall at the 2021 24 Hours of Le Mans. The team continued in the Hypercar class through 2022. In 2023, Signatech stepped back to run two Oreca 07 LMP2 entries in the WEC before returning to the Hypercar category in 2024 with two Alpine A424 prototypes. The highlight of that campaign was a third-place finish at the 6 Hours of Fuji, with the team placing fourth in the Hypercar standings.
Across more than two decades of competition, Signatech built a reputation as a precision team operator equally capable in junior single-seaters and the top tiers of endurance racing. The partnership with Alpine became a defining characteristic of French manufacturer-backed sportscar involvement in the WEC, and Alpine's 2024 equity stake formalised what had long been a de facto works relationship. The team's work running the all-female Richard Mille Racing lineup also contributed to broader efforts to expand opportunities for women in top-level endurance competition.
