Originally we started off as a marketing outfit dealing in various products under the name of D S MAX. While on selling track we encountered bumps and upheavals viz. Duplicate product, infiltration, deceptions, cheating etc reported by our customers. We fond out that most household has had some kind of problems in respect of family fraud, infidelity, treachery, failed marriage, extra marital relationships etc. Many desired to hold pre-matrimonial enquiries. Around the same time we were approached by one very experienced ex-cop of Kolkata detective department who promised to bring along a band of experienced sleuths. He induced us to start detective service.

We formed our group and started investigation / probing work. We received soon high acclamation for delivering prompt, accurate investigation reports. Our company’s name was changed over to D S & I B. In addition to investigation work we also started providing security services. Here we have on our rolls ex-army personnel many in members await in readiness for deployment. Soon we spread out our domain from individuals to banks, manufacturing Units, business houses and schools. This venture is for the last half decade having devoted over half decade previously in marketing / selling goods and services.
