Welcome to the PAX Spring-21 Cohort!

After a successful inaugural Fall session, Pax Momentum is delighted to announce our Spring-21 cohort! Through a rigorous selection process, we’ve curated a group of diverse companies that we’re excited to help grow.  Pax focuses on a unique niche of growing companies that are ready to build out their go-to-market strategy.  With that vision, we’ve selected a group of companies from diverse industries, united by their readiness to harness their market potential and boost their growth. 

Each session, Pax looks far and wide for promising start-ups. We have companies from the east coast in Pittsburgh, Bethesda, New York, and Philadelphia; from the Midwest in Chicago and Ann Arbor; and from the south in Atlanta. We even reached outside the country and found amazing startups in Santiago, Chile and Toronto, Canada! Our companies also come from a variety of verticals; this group includes climatetech, healthtech, eCommerce, fintech,  and HR startups. 

The Spring 2021 Cohort’s start-ups are led by a diverse group of founders who are passionate, driven, and committed to their work. 55% of our companies are led by underrepresented founders, including 44% female-founded companies. The cohort is also 20% international. 

The Pax Momentum Accelerator exists to help these companies scale and reach new heights. Over the next two months, these founders will hone the skills necessary to build repeatable, scalable sales processes. From high-level strategic decisions about product positioning and the customer journey, to the nitty gritty of digital funnels and sales meetings, we’ll teach them how to take their operations to the next level.

Each company in the cohort is breaking new ground in their industry. Our climatetech companies each have innovations that will help make our planet more green — two of them literally! Bloomfield Robotics is at the frontier of the precision farming movement, using AI to improve farming efficiency, while Just Vertical lets you grow your own produce in their vertical hydroponic gardens. Sesame Solar is expanding the usability of solar power in remote areas with their modular solar units that can be sent anywhere in the world.

We’ve selected two eCommerce companies that are helping retailers streamline the online shopping experience from start to finish, and back again with returns. Sweft allows stores to streamline launching their products online, while Lillii’s Freeing Returns ameliorates the inefficiencies of the returns process.

Our HR tech companies help companies strengthen teams and improve employee engagement and sense of belonging. Rallybright’s performance management platform helps teams to identify improvement areas, and Storybolt helps companies overcome biases and improve engagement with award winning documentaries. 

In fintech, Protosure’s no-code insurance platform allows insurers of all sizes the capability to build, iterate, and distribute new products on the cloud. Meanwhile, in healthtech, Pegasi is making a big impact in healthcare outcomes by empowering doctors and researchers across Latin America to organize and access data on and offline.
