Lendy Beatty

Co-Founder & Chief Innovation Officer

Lendy Beatty is the Co-Founder and Chief Innovation Officer of Logical Brands, a Nashville-based pet company with a portfolio of premium brands and products. Logical Brands was formed in 2017, after Beatty decided to leverage her deep expertise in private brand product design, retail and supply chain to launch Playology, a line of innovative, premium dog toys that rapidly grew to #2 in value share in 5 short years.

We worked with Lendy and her co-founder and husband, Adam Beatty, on the launch of their brand portfolio, helping uncover key consumer insights, developing brand and marketing communication and advising on go-to-market strategy. Our work started with Playology, a super-premium line of scent-based toys designed for longer pet engagement; Hound 2O, a premium line of durable toys: Greeeen, a selection of sustainably manufactured toys; and Moose and Pig, a greeting card collection channeling the voice of pets.

Lendy has combined her passion and deep understanding of dogs and how they play, with consumer and shopper insights to drive the design of the brand portfolio. Playology is rooted in the understanding that scent strongly engages pets, and the products are designed with a proprietary scent release system that drives captivating play experiences. Over time, the line has expanded to cover the entire life stages of dogs: Playology Puppy, which helps puppies’ sensory development from 4 weeks to 4 months, and Playology Senior, to meet the needs of aging dogs, with a softer bite to keep them engaged well into their senior years.

Theme: Innovation grounded in deep consumer insight – shopper and end user – is the greatest source of brand and product differentiation. Logical Brands has disrupted a staid pet category and delivered meaningful innovation that improves the well-being of pets.

Charles Reppucci

Chief Operating Officer

Charlie Reppucci served as Chief Operating Officer of Hinckley Allen, a Boston-based law firm with a diverse practice focused on the Northeast. In this role, Charlie led a team of functional leaders that enabled the work of the firm’s Managing Partner, Executive Committee and Practice Leaders, where he brought new approaches to professional services that helped improve the firm’s competitive position. As COO, Charlie took a hands-on approach to driving change and transformation, making significant investments in marketing, business development, IT and talent management that were foundational to the firm’s success.

We worked with Hinckley Allen from 2003-2018, when Charlie retired after more than 20 years as COO. Hinckley Allen was our first and only client in professional services, but Charlie leveraged the full range of our capabilities as he helped drive impressive organic and inorganic growth over the period. Hinckley Allen pioneered brand and marketing fundamentals, from customer segmentation and targeting, brand positioning, go-to-market strategy and sustained multi-channel marketing investment to help build reputation and market recognition as a regional firm. Over our 15 years collaborating, Charlie tapped into our data analytics capabilities to understand business performance, identify drivers of client satisfaction and retention, assess industries and geographic markets, and inform ‘where to play and how to win choices’, including evaluating M+A opportunities. During this time, the firm joined the AmLaw 200, and is broadly recognized for its strong financial performance, and as an exceptional workplace.

Theme: Strategy, brand and marketing fundamentals can be applied across industries, and can help exceptional leaders create meaningful competitive advantage that accelerates growth

Stephanie Hogarth

VP, Chief Marketing Officer

Stephanie Hogarth serves as VP, Chief Marketing Officer of Children’s Hospital of Philadelphia, the world’s first pediatric hospital and one of the largest pediatric healthcare systems in the country. For more than 15 years, Stephanie has helped to build the institution’s brand, reputation and market position inclusive of its distinguished research enterprise, academic medical center hospitals, regional network, global medicine program and Foundation, which serves as the conduit to support CHOP’s philanthropic mission. 

We worked with Stephanie and the leadership team at CHOP from 2008-2010, when the organization began an ambitious growth strategy to expand the enterprise regionally, nationally, and internationally, and to grow its donor base to diversify revenue and invest in the institution’s mission. Our work spanned brand development, growth strategy, marketing strategy and planning as well as organizational design, leveraging industry best practice and the deep experience within Stephanie’s team at CHOP to optimize Marketing’s contributions to enterprise growth. Over the last decade, the institution has continued on an aggressive growth trajectory, expanding the reach and impact of its breakthrough research, deep and differentiated subspecialty expertise and world-renowned faculty to further pediatric medicine in the community and around the globe.   

In the time since we first worked together, Stephanie has continued to evolve the Marketing  organization to contribute both upstream to enterprise strategy and downstream to integrated full-funnel marketing and communications strategy and execution—an approach that has successfully extended the reach of the CHOP brand.  In 2012, we nominated Stephanie for, and she received, the Non-Profit Marketer of the Year, awarded by the American Marketing Association in recognition of best-in-class capabilities and performance among healthcare and other not-for-profit organizations. 

Theme:  Brand building and strategic marketing are key growth levers to expand reach into new markets and with new audiences, helping to build reputation and drive enterprise growth.
