Konsistent is the unique preventative and education tool helping to tackle bias, harassment, and exclusion in the workplace. Konsistent detects and flags harmful language in real-time and provide resources to help educate employees on potential unconscious bias and aggressions. Konsistent fights harassment and exclusion from the prevention to the cure: companies can identify potential problems early on and take action to prevent them from happening. An inconvenient truth: In 2019 alone, the U.S. Equal Employment Opportunity Commission (EEOC) received over 7,514 claims of sexual harassment, resulting in $68 million in direct settlements. * 30% of employees say they are subjected to moral harassments at work. * 12% say they have been "repeatedly insulted or subjected to insulting behaviors" by a supervisor. * 48% of private sector employees say they have experienced discrimination in the workplace. * 27% of men and 52% of women report being victims of sexual harassment at work. * 46% of women say that harassment caused them to leave jobs or switch careers. * 52% of employees who have experienced workplace harassment reported feeling depressed, having symptoms of anxiety, difficulty sleeping, and even suicidal thoughts. * And 80% of harassers dont even know theyre harassing. Your companys unsolved incidents of workplace harassment and discrimination will eventually lead to costly lawsuits, employee burnout, and high turnover rate. This catastrophic issue will end up costing your company millions of dollars in the long run, and in worse cases, can even lead to tragic consequences. The mental health impacts of these problems are real, and they can have a devastating effect on peoples lives. You cant afford to ignore this problem any longer. A company is only as strong as its employees - so make sure your employees are happy, healthy, and productive with Konsistent. Do not hesitate to contact us (contact@konsistent.app) to be a part of the solution.

iytro was founded in 2019 when we noticed that many early stage startups struggle with marketing, often unsure of where to start. We knew there was a better way to help them get over the hump(s) and bump(s) to growth: through immediate access to marketing experience, skills and talent. We wanted to deliver something flexible and cost-efficient and so the ‘Part-Time CMO’ was born. After more than 150+ successful missions in almost every industry you can think of (and some you can’t), within a European ecosystem rapidly outgrowing its ability to provide the right talent at the right moment… our mission is now more important than ever. OUR GOAL To help early stage businesses grow faster by providing immediate access to specialized, experienced marketing expertise. OUR CLIENTS Startup Founders Venture Capitalists Corporations with new and unproven ventures Scaleups with a fundamental marketing problem or gap in their knowledge Including: Algolia, Evaneos, France Digitale, 360 Capital, Inovexus, Five Seasons Ventures, Alven, 2CFinance, Cheerz, Dathena, Micropep, Prismic, Seyna, Sonio, Whoz, Eatwith, KMTX, Numa, Jus Mundi, Oud Paris, Snapcall, Wakeo, Bloomflow, WeMoms, Figures, Continuity, Worldia …
