Insight Architecture conveys architecture through tours, events, teaching, publishing and building.

Insight Architects (formerly Guiding Architects Rio de Janeiro) was founded in 2013 by Barbara Iseli, Bernardo Lopes, Marcio Nisenbaum and Jason Baumann.

In February 2016, GA Rio de Janeiro officially became part of the global network Guiding Architects. The network consists of independent companies and organizations in 40 major cities around the world that offer qualified architecture tours, guided by local architects, architecture historians and journalists.

In May 2018, GA Rio de Janeiro changed its name to Insight Architecture, aiming to broaden its scope from just guided tours to also include lectures, workshops, conferences, publications and designing projects.
