Wonderbelly is a modern consumer health brand reinventing the $16B gut health category. The company launched in 2022 with its first product, a next-generation antacid that is effective, clean-label, and free from the artificial dyes and aluminum found in legacy brands.

The company was founded by brothers Noah and Lucas Kraft, who bring together backgrounds in entrepreneurship, branding, design, and operations after spotting a category that hadn’t meaningfully evolved in decades.

Wonderbelly set out to build a gut health Masterbrand, that affects millions of people daily. Wonderbelly’s commitment was to destigmatizing the conversation as significantly improve healthier products.

BrandProject invested in Wonderbelly’s pre-seed round in 2021 and led the seed round in 2022. Wonderbelly was acquired by Proctor & Gamble in 2026.
