For founders promoting innovative technologies, hype often attracts the resources necessary to grow a new venture. Hype is gaining prominence in entrepreneurship literature, and it is understood that many entrepreneurs jumpstart their ventures by promoting optimistic, future projections to entice stakeholders. Unfortunately, little is known about how skilled cultural founders generate hype to attract stakeholders. In our study, we examine how founders function as “skilled cultural operatives” to positively manipulate the emergence of hype. We conduct an experiment on 148 members of the media, and we find support for our theorizing in that founders who display their entrepreneurial abilities (swagger) combined with an authentic emotional commitment to the venture (passion), it increases media expectations (hype).</p></div><div><h3>Executive summary</h3><p>For the founders of innovative technologies, hype is not just beneficial, it is a strategic necessity. Hype is characterized by an overinflated interest in emerging technologies where future expectations outweigh current capabilities. It serves as a magnet for essential resources such as funding and customer interest. This dynamic, albeit critical, is often misunderstood and underestimated, in particular as regards the founder's role in its development. It is therefore of paramount importance to unravel the nuances of how founders contribute to the creation of hype.</p><p>This study explores founders as “skilled cultural operatives,” adept at using their cultural toolkit through sensegiving to inflate media expectations, thereby creating hype. Sensegiving in entrepreneurship involves a mix of verbal and non-verbal cues to communicate, clarify, and justify new technology. It is particularly important if there are no historical references or industry standards. The study posits that effective sensegiving through metaphorical reasoning, in which founders display their confidence and passion in a highly visible and expressive way, is key to generating media attention to generate hype.</p><p>In the present study, the concept of “swagger” emerged as a critical sensegiving mechanism. Defined as a conspicuous display of confidence through various expressions, swagger is a tool for founders to project their abilities and attract media coverage. However, this swagger, even if it attracts attention, may initially be perceived negatively, as a mere showmanship without substance. This research provides a nuanced understanding of this perception and shows that if swagger is infused with genuine passion, it transforms into a powerful catalyst for generating hype.</p><p>Conclusively, this study enriches the literature on hype cycles, moving beyond mere descriptions to a deeper understanding of how founders generate hype. By introducing and operationalizing the concept of entrepreneurial swagger, this study expands the range of sensegiving strategies available","PeriodicalId":51348,"journal":{"name":"Journal of Business Venturing","volume":null,"pages":null},"PeriodicalIF":7.7,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141984852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As consumer behaviors changed during the COVID-19 crisis, smallness and innovativeness became liabilities while scale and familiarity became indispensable, favoring larger breweries over prototypical members. This shift exposed hidden divisions within the category, challenging long-held beliefs in shared fate and entrenching heterogeneity among members.

Based on longitudinal data from a sample of 840 entrepreneurs in four European countries, our study shows that, with increasing biological age, entrepreneurs experience less emotional exhaustion due to their enhanced psychological capital and because they apply less entrepreneurial strategies which focus on the creation of new market opportunities and the development of new products and services. In addition, we highlight the still under-explored role of entrepreneurs' felt age gap by demonstrating that, among the same age-group, individuals who feel younger than their biological age gain well-being benefits because they possess higher levels of psychological capital and become less exhausted from the application of entrepreneurial strategies. In conclusion, our study offers two significant contributions to the literature on entrepreneurial well-being. First, we introduce the concept of the ‘Hebe Effect in entrepreneurship’, named after the Greek goddess of youth, which demonstrates how feeling younger than one's biological age acts as a buffer against stress and protects entrepreneurs from the strains of entrepreneurship. Second, we deepen understandings of how entrepreneurs' strategic choices evolve over their lifespan and influence their personal well-being.

Despite significant research conducted on aging and entrepreneurship, studies have yet to explore the interplay between biological age, subjective age, and emotional exhaustion. Furthermore, the manner in which entrepreneurs subject themselves to, and protect themselves from, emotional exhaustion across their lifespans remains severely underexplored. This lacuna is particularly striking given global trends of increased life expectancy, the burgeoning number of older individuals engaging in entrepreneurship, and the risks posed by emotional exhaustion to entrepreneurial efforts and individuals' lives, as well as the societal costs related thereto.</p><p>By using the theory of social and emotional aging (SEA), we investigate how biological age and subjective age impact entrepreneurs' emotional exhaustion.
