The spotlight on edtech grows brighter and harsher: On one end, remote-learning startups are attracting millions in venture capital. On the other, many educators and parents are unimpressed with the technology that enables virtual learning and gaps remain in and out of the classroom.

It’s clear that edtech’s nebulous pain points — screen time, childcare and classroom management — require innovation. But as founders flurry to a sector recently rejuvenated with capital, the influx of interest has not fostered any breakout solutions. As a result, edtech investors must hone their skills at sorting the innovators from the opportunists amid the rush.

Lucky for us, investors shared notes during TechCrunch Disrupt and offline regarding how they are separating the gold from the dust, giving us a peek into their due diligence process (and inboxes).

Putting profitability over growth

The pandemic has broadly forced founders to get more conservative and prioritize profitability over the usual “growth at all costs” startup mentality. Growth still matters, but within edtech, the boom comes with a big focus on profitability, efficacy, outcomes and societal impact.

“The goal of all of education is personalized learning, when every student receives exactly the instruction in the way that they need it at the time that they need it. And that’s really, really difficult to do if you’re trying to have one person teach 180 students,” said Mercedes Bent of Lightspeed Venture Partners. “And so I’ve been excited to see more solutions that are focused on creating smaller class sizes that are also focused on allowing students to connect with people outside of their homes as well.”

During Disrupt, Reach Capital’s Jennifer Carolan brought up a recent Netflix documentary, “The Social Dilemma,” which illustrates the impact screen time can have on society. When vetting companies, Carolan said she wanted to see founders who have considered how their products may impact young users.
