Build Wealth is a private-markets investment platform created by Walker Deibel, the St. Louis-based author of Buy Then Build and creator of the Acquisition Lab accelerator. It gives accredited investors access to vetted private deals on preferred terms, packaged as limited liability company units in deal-specific vehicles. Recent offerings include an oil and gas vehicle (BuildEnergy I) and a games-studio vehicle (BuildInteractive II) that invests alongside Deibel. The platform sits inside a broader ecosystem that also includes the Buy Then Build and Acquisition Lab brands.
