Est. 2019 · Letter no. 001Fresh every day,
Fresh every day,
for the whole family.
We started Sigma Mart as one corner shelf of family-farm produce. It grew sideways — not upward — into an online supermarket that keeps the same promise: fresh, honest, in-under-90-minutes.
Principles
How we stock the aisle.
Fresh, not frozen
Picked within 48 hours. If it can't be, it's not on the shelf.
In-under-90-minutes
Same-day, window-based delivery. Pick a time, we'll show up.
One quality check
Every item is inspected by a named buyer. Not outsourced, not automated.
Family-first pricing
Refill programs, weekend 2× points, and a $10-off welcome letter.
