FAQ
Yes. Our four most recent startup runs were for Y Combinator companies: screenpipe (S26), Ontora, Manicule, and Pairio (P26), each delivered in time for their batch. Demo Day merch is usually a small, fast run, so send us the date first and we confirm whether the timeline is realistic before you commit.
Yes. We ship direct to San Francisco offices, co-working spaces, and event venues. Local drop-off is available for Bay Area orders and arranged case by case. Include your delivery address and the date you need everything by in the quote request.
Yes. Booth staff apparel and giveaway swag are common orders. Conference dates do not move, so we work backwards from your load-in date and confirm the production window in writing before anything goes to print.
Yes. Employee welcome kits are a core use case: matched hoodies, tees, and caps packed per recipient. If your team is split across an SF office, other Bay Area sites, and remote locations, we can arrange multi-destination shipping from one run.
Yes. Gifting programs run on the same premium blanks as team merch, with embroidery or screen printing and per-recipient pack-out. Tell us the recipient count and the date, and we quote in writing.
