FAQ

What marketplaces are Berkeley businesses building?
Berkeley entrepreneurs launch artisan food marketplaces connecting Gourmet Ghetto producers with national buyers, academic resource platforms for UC Berkeley researchers, sustainable goods marketplaces reflecting the city's eco-values, local service directories, and specialty product platforms serving Berkeley's niche consumer interests.
How long does marketplace development take?
An MVP with buyer-seller matching, payments, and search takes 3-5 months. Full platforms with reviews, disputes, analytics, and mobile apps need 6-12 months. Berkeley founders should launch lean — validate with the UC Berkeley community before scaling nationally.
What drives marketplace costs?
User role complexity, payment flows, verification systems, and matching logic affect pricing. A listing marketplace costs less than a platform with escrow, commission management, and real-time booking. We build modularly so Berkeley startups add features as revenue grows.
How do you handle marketplace payments?
Stripe Connect for split payments, vendor payouts, commission tracking, and tax reporting. For Berkeley marketplaces connecting international academic suppliers or artisan producers, we configure multi-currency and cross-border payment flows.
Can the platform serve both local Berkeley and national users?
Yes. We architect marketplaces that start hyperlocal — serving Berkeley and the East Bay — then expand without re-engineering. Location-based search, shipping zones, and regional pricing scale from campus to national as your vendor base grows.
How do you ensure vendor quality?
Seller verification workflows, product approval queues, reviews, and content moderation. For Berkeley's sustainability-focused marketplaces, we add mission alignment criteria — verifying organic certification, fair trade status, or local sourcing that your platform champions.
How does development work?
We validate data models and payment flows in a prototype first, then build in sprints. Bi-weekly demos show real transactions flowing through the system. Berkeley founders test as both buyer and seller throughout.
What support do marketplaces need after launch?
Vendor onboarding tools, transaction monitoring, fraud prevention, and feature iteration. Growth-phase retainers cover technical maintenance plus product development. Most Berkeley marketplace clients expand features quarterly based on user feedback.
