The main reason that we could possibly develop the free software for the SMEs contractors is we received sponsorships from building material brands, modern trades, manufacturers, banks, and real estate developers. They give us the trust and support to be digital marketing channel and maintain customer relationship digitally. All these amounts that we got, we reinvest to create tools and knowledges to make all SMEs contractors stronger. BUILK is an entirely impartial platform that is able to work with any brands to build a powerful society together. We are changing construction industry from offline to online while building up our “BIG DATA” as our key asset.
