“When I was trying to get pregnant, I felt like there were always babies in my face,” says Silicon Valley alum Halle Tecco, 35. Every pregnancy test or fertility tracker featured some cherubic newborn—or packaging dosed in nauseating hues of baby blue or pink, she recalls. That kind of sensitivity—or perhaps a more emotionally intelligent sensibility—is precisely what Tecco hopes to offer with Natalist, a new startup selling bundles of sleek and educational conception essentials.
