Global Social Buying Community

Since launching in February 2021, we're now 2,000 + Members.

We create value through Social Buying by developing new innovative products, bringing back legendary discontinued products and getting wholesale discounts.

We are building the Connex by connecting BMW M communities and brands from around the world.

They support the Connex because we stick together.

Matt's the man. The Connex have literally made me save 5,000$ this year on my E92 M3 Clubsport build.


Matt is sourcing products I never thought I could get my hands on. The Connex is the real deal.
