Horstmann joined Worcester Warriors from Harlequins in May 2005. He led the team on many occasions and made 173 appearances for the club.
Horstmann was a firm favourite of both the players and supporters and was voted Players' Player-of-the-Year in the 2005–06 and 2006–07 seasons and managed a double in 2008–09 when he was voted both Club Player-of-the-Year and Players Player-of-the-Year.
The Number Eight made his 150th appearance for the club during the 2010–11 season, a year when he was named vice captain and captained the side in the absence of Chris Pennell.
In May 2012, he signed a two-year contract at Exeter Chiefs.[3] In 2014 he was part of the team that won the LV Cup and was rewarded man of the match in the final against Northampton Saints. In 2017, he was part of the team that won the Aviva Premiership at Twickenham.[4] At the end of the 2016–17 season Horstmann was presented with 'Club Man of the Year' at the End of Season Awards Dinner.
In the autumn of 2017 Horstmann launched a new training company, Team Kai, teaching leadership and teamwork skills and strategies based on his experiences operating in high performing teamwork environments during his rugby career. www.teamkai.co.uk
