In recent dealmaking news, Sesame Workshop and Reach Capital unveiled a new partnership to support start-ups. And a social learning network for middle and high school students and a math tutoring company received funds from the investment community.

Sesame Workshop Partners with Reach Capital: Sesame Workshop, through its Sesame Ventures investment arm, and Palo Alto, Calif.-based Reach Capital have recently formed a partnership “to help grow the next generation of educational technology startups,” according to a statement on the Sesame Workshop website.

Reach Capital co-founder Jennifer Carolan said in a May 18 blog post that the firm “will leverage Sesame Workshop’s deep expertise in this space to grow our early childhood investing,” adding that “in the year since Reach launched, the Sesame team has supported our portfolio by providing one-on-one mentorship, offering strategic support and sharing research.”

Tanya Haider, executive vice president of strategy, research, and ventures of Sesame Workshop noted in the company’s website statement that “Reach Capital shares the Sesame Ventures belief in mission-driven entrepreneurs and their ability to leverage technology to educate children.”

Reach Capital is a $53 million venture fund founded in 2015 that backs ed-tech startups. Sesame Workshop did not disclose the amount it is investing in Reach; however, Haider told Recode that it’s “not a huge sum of money.”

Earlier this year, Sesame Workshop announced the launch of Sesame Ventures and its partnership with Collaborative Fund to focus on early-stage startups in the areas of education technology, health and nutrition and social, cultural and family development.
