the industry has a trust problem.
sunday. was built around three principles: u.s. manufacturing, independent verification, and radical transparency.
our philosophy
we believe trust should be earned, not assumed.
sunday. was founded on a simple realization: finding a trustworthy supplier shouldn't feel like a gamble. too often, researchers are left to rely on marketing claims, incomplete documentation, or anonymous suppliers with little transparency into how products are sourced, tested, and handled.
we thought there had to be a better way.
so we built sunday. around a different philosophy, one centered on verification, accountability, and transparency. every product begins with careful supplier selection. every lot is supported by documentation. every batch is reviewed before it reaches you. we prioritize independent testing, lot-level traceability, and clear communication because trust is built through evidence, not promises.
size is never the goal. trust is.
