In its third year of existence and poised to double its workforce, Warby Parker attributed its success to an innovative approach in the eyewear industry and to the company culture that supported it. With a mission combining social and business goals, the company had articulated a stakeholder-centric model that benefited consumers through high-quality, fashionable, and affordable eyewear: the global community by donating, through sustainable channels, one pair of glasses per every pair sold; employees through a fun culture and inspiring work; and the environment, by becoming carbon neutral. The case covers the decisions that Warby Parker must make at the beginning of its third year of existence as a consequence of growth and in order to avoid losing momentum. Some of the challenges that Warby Parker faced were maintaining the company culture, finding adequate partners to preserve the quality of the "Buy a Pair, Give a Pair" program, and devising an integrated online and offline marketing strategy that fit the brand personality.

The note articulates the ways in which strong stakeholder-company relationships developed through corporate social responsibility initiatives and other types of social strategies deliver bottom line benefits.

In 2011, the PNC Financial Services Group announced the addition of $250 million to the $100 million that it had pledged to its early childhood education program, Group Up Great, in 2003. The case serves as an update to the "PNC Financial: Grow Up Great (A)" case, which outlined the design and implementation of the program and presented key challenges. The (B) case will show some of the program's responses to challenges like the strategic integration to Grow Up Great into the bank's business; the introduction of the program to new markets following the bank's geographical expansion; and the measurement of the programs' social impact.

At the end of 2011, the founders of the China Greentech Initiative (CGTI) wanted to grow the company while respecting its unique hybrid business model that combined a collaborative open source community with more traditional strategic research services. The case follows CGTI from its initial goal of establishing a road map for the Chinese green technology market, to further catalyzing the sector through a combination of collaborative network building and customized advisory services. CGTI's hybrid business model and dual mission of profit and social value creation complicated the founders' decisions as they considered different expansion options, including new product and service offerings, and potentially expanding geographical coverage.
