<p>Impact Opportunity and Theory of Change can be tricky concepts, but they both have a relatively clear structure. Scale can happen in many different ways, which makes it a little harder to describe with a single example. Instead, here are two Solver teams with very different Strategies for Scale, reflecting their unique solutions:</p>
<p><a href="https://solve.mit.edu/challenges/community-driven-innovation/solutions/8143" target="_blank">WheeLog!</a> provides detailed crowd-sourced maps and information on accessibility for wheelchair, cane, and stroller users, enabling them to access new places and opportunities. About 20 million people in Japan need to use accessible pathways, and, globally, there is a much larger opportunity for impact and scaling. Mio Yamamoto from WheeLog! speaks more about their Strategy for Scale in the first video below. (You can view more of this interview in <a href="/courses/course-v1:MITx+0.SolveX+2T2021/jump_to_id/505ec9c9172742c29d383d4162b853c2" target="_blank">WheeLog!'s video library</a>.)</p>
<p>In contrast to WheeLog!'s approach and solution, <a href="https://solve.mit.edu/challenges/circular-economy/solutions/7457" target="_blank">Graviky Labs</a> captures carbon-rich air pollution and recycles the carbon into Air-Ink, which can be used as pigment for printing or dye instead of causing respiratory damage. The CEO of Graviky Labs, Anirudh Sharma, explains in the second video below how scalable his team's offering is for a global market.
