In 2020, engineering firm Velentium faced an unprecedented ask: partner with a small medical device company and a very large vehicle manufacturer to increase emergency ventilator production from hundreds per month to thousands per week—in just 28 days. Serving on the frontlines of pandemic response is enough pressure to cause any size business to buckle, but the small firm thrived and even doubled in size to complete their manufacturing scale-up known as Project V: seven months of work in six weeks. Velentium’s cofounder Dan Purvis attributes their extraordinary success to their decade-in-the-making company culture, which buoyed them in the face of an unforeseeable crisis. In 28 Days to Save the World , he lays out how to harness the power of organizational culture to prepare your small business to weather any challenges ahead.

He shows how a well-crafted culture: Reveals the right path in a crisis - Taps into team members’ inner motivation - Unites leaders and followers - Compels action in “made for you” moments - Enables you to step up to global challenges - Catalyzes deep connections between people inside and outside your organization When a defining moment arrives for your organization, will your team be ready? 28 Days to Save the World is an essential resource for ensuring that you are.
