Republican consulting firm Axiom Strategies is announcing Monday it’s entering into a strategic partnership with The Prosper Group, a digital marketing agency.

For these two firms, which have worked together for over a decade, the partnership is an opportunity to increase efficiency and share political expertise.

For the political consulting world, it’s a sign the industry may be trending toward greater consolidation, especially with digital now commanding an ever larger share of the market.

Axiom currently has 52 clients in Congress, and now the two firms combined will represent 74 lawmakers. That’s a quarter of all Republicans in the House and Senate.

Axiom was founded in 2005 by Jeff Roe. A veteran of Missouri Rep. Sam Graves’political operation, he managed Texas Sen. Ted Cruz’s 2016 presidential campaign. Kristen and Kurt Liudhardt, a husband and wife team, founded The Prosper Group out of Indianapolis in 2006. Their firm has worked with President Donald Trump, Vice President Mike Pence, Cruz and Wisconsin Gov. Scott Walker, among others.
