Devfi is a digital transformation firm founded in 2012 whose own contact page gives its headquarters as 8150 Leesburg Pike, Vienna, Virginia, matching its Virginia State Corporation Commission filing and its federal vendor record. Its published AI work covers AI strategy consulting, machine learning model development including text analytics and deep learning, and data pipeline engineering, with cloud, business intelligence, Internet of Things and DevOps work beside it. Directory profiles give its headcount three different ways, from about ninety-five to several hundred, and one classifies it as a data analytics firm rather than a software firm, so its public profile is inconsistent and no size is recorded here. Directories variously place it in Columbus, Ohio and in Sacramento; both are contradicted by the firm's own address.
