CropWire — Direct Farm-to-Restaurant Produce Marketplace for Local Chefs
Restaurant chefs in mid-sized cities are drowning in Sysco invoices for produce grown 2,000 miles away while local farms 30 minutes out cannot fill their trucks because they have no distribution channel. CropWire is a weekly pre-order marketplace where local farms post available harvests on Monday, chefs pre-order by Wednesday, and farms deliver Thursday — zero broker markup, no minimum order nonsense.

What is it?
Specialty and farm-to-table restaurants spend 28-35% of revenue on food costs, and local sourcing premiums are eaten by distributors who take 35-50% margin. Small farms within 50 miles of any mid-sized city have surplus produce every week but no reliable buyer channel beyond farmers markets. CropWire is a two-sided weekly marketplace: farms post available inventory with quantities and prices on Monday, restaurants browse and pre-order by Wednesday, farms confirm and deliver Thursday. The platform takes 8% from the farm side. No monthly fees for buyers to remove friction. MVP is a single city with 10 farms and 15 restaurants — the weekly cadence eliminates the cold-start freshness problem that kills produce marketplaces. Buildable now because Supabase real-time covers inventory state, Stripe Connect handles split payments to farms, and Resend manages the weekly harvest notification emails.
Why now?
Post-pandemic supply chain awareness pushed farm-to-table sourcing demand to an all-time high among independent restaurants, and Stripe Connect's instant marketplace onboarding makes split payments trivial to implement without a money transmitter license.
- ▸Weekly harvest board where farms post available produce with quantity, price per unit, and delivery zip codes served.
- ▸Chef pre-order cart with Wednesday cutoff timer and Thursday delivery confirmation.
- ▸Stripe Connect split payment that routes 92% to farm and 8% to platform automatically.
- ▸Resend weekly email digest to all buyer accounts showing that week's available harvest from farms in their radius.
Target Audience
Independent restaurants sourcing local produce (40k+ in US mid-sized cities) and small farms with surplus weekly harvest (100k+ USDA-registered small farms).
Example Use Case
Chef Maria at a 60-seat farm-to-table restaurant pre-orders 20 lbs of heirloom tomatoes and 15 lbs of microgreens from two local farms on Wednesday morning, pays through CropWire, and receives delivery Thursday before lunch prep — cutting her produce cost by 18% versus Sysco.
User Stories
- ▸As a farm owner, I want to post my weekly surplus harvest on Monday and receive confirmed orders by Wednesday, so that I can plan delivery routes and reduce unsold produce waste.
- ▸As a restaurant chef, I want to browse available local produce by Wednesday and pre-order for Thursday delivery, so that I can plan my weekly menu around fresh local ingredients at lower cost than distributors.
- ▸As a platform operator, I want Stripe Connect to automatically retain 8% of each order, so that revenue is collected without manual invoicing.
Done When
- ✓Farm listing: done when a farm can post a produce listing with quantity, price, and delivery zip codes and it appears on the buyer harvest board within 60 seconds.
- ✓Buyer order: done when a chef adds items to cart, checks out before Wednesday cutoff, and receives a confirmation email with delivery details.
- ✓Stripe Connect payout: done when an order payment routes 92% to the farm Stripe account and 8% to the platform account automatically within 24 hours of order confirmation.
- ✓Weekly digest: done when all registered buyers receive a Monday morning email listing available produce from farms within their set radius.
Is it worth building?
8% take rate on $500 average weekly order x 30 restaurant buyers x 52 weeks = $62,400 gross marketplace volume = $4,992 revenue/year per city. 3 cities = $15k/year. Scales non-linearly with city count. Math assumes 30 active restaurant buyers per city spending $500/week on local produce.
Unit Economics
CAC: $20 via in-person farm market visits and restaurant cold calls. LTV: $1,248 per restaurant buyer (8% of $300/week x 52 weeks). Payback: 1 week. Gross margin: 85% after Stripe fees.
Business Model
Marketplace commission
Monetization Path
8% commission on farm-side payments via Stripe Connect. No buyer fees. Optional $49/month premium farm listing for priority placement.
Revenue Timeline
First dollar: week 3 via first completed farm payment. $1k MRR equivalent: month 3 at $12.5k weekly volume. $5k MRR: month 8 across 3 cities.
Estimated Monthly Cost
Vercel: $20, Supabase: $25, Resend: $10, Google Maps API: $15, Stripe Connect fees: variable. Total: ~$70/month fixed at launch.
Profit Potential
Full-time viable at 8-10 active cities with healthy weekly volume per city.
Scalability
High — city-by-city expansion, national farm network, private label sourcing for restaurant groups, B2B catering sourcing.
Success Metrics
Week 4: 5 farms and 8 restaurants completing real weekly orders. Month 2: $5k gross marketplace volume per week. Month 3: zero order fulfillment failures.
Launch & Validation Plan
Visit 5 local farms at the nearest farmers market, explain the concept, and get 3 verbal commitments before writing any code. Then cold call 10 local independent restaurants.
Customer Acquisition Strategy
First farm: visit the nearest farmers market on Saturday and pitch the top 3 vegetable vendors on a free 60-day listing with no commission. First restaurant: cold walk into 10 independent farm-to-table restaurants with a printed one-pager showing the weekly harvest cadence and 18% cost savings estimate. Ongoing: Instagram for farm content, James Beard Foundation local chapter events, restaurant association newsletters.
What's the competition?
Competition Level
Low
Similar Products
Barn2Door (consumer CSA focus, not B2B restaurant), Local Line (farm management, not marketplace), Sysco (national distributor, no local sourcing) — CropWire fills the B2B weekly pre-order gap for local farm to restaurant.
Competitive Advantage
Sysco and US Foods have no local sourcing layer. Existing farm-to-table apps (Barn2Door) focus on consumer CSA boxes — CropWire targets B2B restaurant buyers with a weekly pre-order cadence that matches kitchen planning rhythms.
Regulatory Risks
Food safety regulations vary by state for direct farm-to-restaurant sales. Research state department of agriculture rules for unprocessed produce sales before launching. Generally low risk for raw produce — no USDA inspection required for farms selling direct.
What's the roadmap?
Feature Roadmap
V1 (launch): harvest board, pre-order cart, Stripe Connect, weekly Resend digest. V2 (month 2-3): farm reliability ratings, order history, multi-city admin. V3 (month 4+): recurring standing orders, farm logistics route optimizer.
Milestone Plan
Phase 1 (Week 1-2): farm posting, buyer browse, and Stripe Connect payout flow shipped. Phase 2 (Week 3): weekly digest email, Wednesday cutoff, and order confirmation live. Phase 3 (Month 2): 5 farms and 10 restaurants completing real weekly orders in one city.

Core User Journey
Chef signs up -> browses Monday harvest board -> adds produce to cart -> checks out by Wednesday -> receives delivery Thursday -> rates farm reliability.
Architecture Pattern
Farm posts harvest listing -> Supabase inventory table updated -> Resend weekly digest fires Monday to all buyers in radius -> buyer adds to cart -> Stripe Connect charge on order confirm -> Thursday delivery confirmed by farm -> 8% platform fee retained automatically.
Data Model
Farm has many Listings. Listing has produce type, quantity, price, delivery zips, week. Buyer (Restaurant) has many Orders. Order has many OrderItems each linked to a Listing. Payment belongs to Order with platform fee tracked.
Integration Points
Stripe Connect for split marketplace payments, Supabase Realtime for live inventory state, Google Maps API for farm-to-restaurant radius filtering, Resend for weekly harvest digest emails.
V1 Scope Boundaries
V1 excludes: consumer-facing CSA boxes, farm logistics management, multi-city admin panel, white-label, mobile app, real-time chat between farms and chefs.
Success Definition
A restaurant chef the founder has never met discovers CropWire, pre-orders produce from a local farm, receives correct delivery Thursday, and places a repeat order the following week without any founder involvement.
Challenges
The hardest non-technical problem is supply reliability — if a farm posts 50 lbs of tomatoes and delivers 30, chefs stop trusting the platform. You need a manual reliability rating system from day one and willingness to call farms directly when orders fall short.
Avoid These Pitfalls
Do not launch in a city where you do not personally know at least 3 farms — cold outreach to farms fails at 95% rates and you need verbal trust before the first transaction. Do not build a rating system before you have 10 completed orders — premature social proof infrastructure is wasted. Finding first 5 restaurant buyers will require in-person visits, not email campaigns.
Security Requirements
Supabase Auth with email magic link, RLS scoping farm listings to farm owner, buyer orders to buyer account, Stripe Connect OAuth for farm onboarding, input validation on all listing fields.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and auth, Resend for transactional email, Stripe Connect for payments, Sentry for error tracking, GitHub Actions for CI deploy.
Performance Targets
200 DAU at peak (Monday digest open day). Harvest board loads under 1.5s. Supabase real-time inventory update under 500ms. No caching needed at single-city launch scale.
Go-Live Checklist
- ☐Stripe Connect payout flow tested with real farm test account.
- ☐Wednesday cutoff timer tested across timezone edge cases.
- ☐Sentry error tracking live.
- ☐Vercel deploy on custom domain with SSL.
- ☐Privacy policy and terms published.

First Run Experience
On first run: the harvest board shows 3 seeded demo farm listings with produce photos, prices, and quantities. A buyer can immediately browse, add to a demo cart, and see the Wednesday cutoff timer counting down. No real payment required in demo mode — checkout shows a Stripe test mode badge. Farm dashboard shows a seeded listing with mock order count.
How to build it, step by step
1. Define Supabase schema: farms, listings (produce, qty, price, delivery_zips, week_of), buyers, orders, order_items, payments. 2. Scaffold Next.js app with Supabase Auth for farm and buyer roles. 3. Build farm dashboard page where farms post weekly harvest listings with quantity and price. 4. Build harvest board page for buyers filtered by Google Maps radius from their restaurant address. 5. Implement order cart and Wednesday cutoff timer using Supabase real-time inventory checks. 6. Set up Stripe Connect onboarding flow for farms with automatic 8% platform fee on payouts. 7. Build Resend weekly digest that fires Monday morning listing all available produce in each buyer's radius. 8. Add farm reliability rating (1-5 stars) on order completion by buyer. 9. Build simple admin page showing weekly gross volume, order count, and fulfillment rate per farm. 10. Verify: post a test farm listing, place a test buyer order, confirm Stripe Connect routes 92% to farm test account and 8% to platform account.
