Centrale
Bulk VC applications, one platform. A founder signs up, enters their domain, answers five questions, and gets a startup profile written by Claude, a scored list of investors and a sending inbox, so the first investor email can go out within fifteen minutes of signup.

Supabase project: tldvqiqucfmlnkgxaufy (Achraf SaaS, eu-central-1).
Run it
npm install
npm run dev
.env.local needs NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY and NEXT_PUBLIC_SITE_URL (see .env.example).
How the pieces fit
- Signup calls the
signup function, which creates a pre-confirmed user (Supabase's default mailer only delivers to team members, so email confirmation is skipped for now). A trigger creates the profiles and startups rows.
- Onboarding (
/onboarding) saves each answer as it goes and starts the Firecrawl scrape the moment the domain is entered. Founders who want a deck answer five questions. The last step runs build-profile (Claude) and provision-inbox (OpenMail) in parallel, then match-investors and, when asked for, generate-deck. Every account starts a 7-day free trial.
- Dashboard (
/dashboard): Home, Investors, Inbox, Outbox, Pitch deck, Startup profile, Settings, Billing. Single sends go through send-email; batches and follow-ups are queued in scheduled_emails and sent by process-outbox every minute. Every email carries an open-tracking pixel served by track-open.
- Replies hit
openmail-webhook, which verifies the HMAC signature with the inbox's secret, dedupes by event id, links the reply to the investor by thread, emails the founder from the system inbox, and the insert fans out to the browser over Realtime (toast plus confetti).

Secrets
The Supabase CLI on this machine is logged into a different account, so function secrets live in Supabase Vault and are read through public.get_app_secret() (service role only): OPENMAIL_API_KEY, FIRECRAWL_API_KEY, ANTHROPIC_API_KEY, OPENMAIL_SYSTEM_INBOX_ID, APP_URL, CRON_SECRET, and once Stripe is connected STRIPE_SECRET_KEY and STRIPE_WEBHOOK_SECRET.
Test mode. Until the Vault secret OUTREACH_LIVE is true, every email meant for a directory investor (or an old demo investor) goes to [email protected] with a note naming the real recipient. Override the address with OUTREACH_TEST_RECIPIENT. If you later run supabase secrets set, env vars take precedence over Vault automatically (_shared/core.ts).
Deploying functions
supabase login
supabase link --project-ref tldvqiqucfmlnkgxaufy
supabase functions deploy
(signup, openmail-webhook and track-open need --no-verify-jwt.)
Database
Migrations are in supabase/migrations.
Investor directory. The raw import lives in public.contacts (never readable from the API). A cron job (sync-investors, every minute, 2,000 rows per run) syncs it into public.investors: one row per email, only people with both an email and a LinkedIn profile, with type, stages, sectors, values, role, region and phones derived from the data. Numbers labelled DNC are never shown. A slim private.investor_index (integer keyword ids) keeps search fast as the directory grows.
Access and limits. Founders never read contact details from a table. search_investors, investor_facets, investor_detail, reveal_investor and export_investors are metered security definer functions: contact details are masked until revealed (one credit), exports spend export credits, and plans cap search depth, page size, searches per minute and rows viewed per day. Plans live in public.plans (trial, Starter, Pro).
Known limits
- OpenMail free plan: 3 inboxes per account. The fourth signup gets a clear "inbox limit" message and a Set up inbox button in the top bar and Settings once the limit is raised. Cold sends are capped at 20 a day per new inbox and 30 a day per account.
- Reply notification links use
APP_URL from Vault (currently https://www.centralegtm.com).
- PPTX, KEY and DOCX decks are stored but not read yet; PDFs are read by Claude.
- Search takes about 150 to 300ms on today's 13.5k investors on the smallest Supabase instance. At 200k expect it to scale roughly linearly; move to a larger compute size before importing.
- Billing is Whop: one plan, $149 a month, 7-day trial with a card up front. Trial accounts get profile, scrape, deck and a browsable directory with emails and phones truncated; no inbox, sending, reveals or exports until the plan is paid. Stripe code is kept but unused.
- LinkedIn and WhatsApp outreach are researched in
docs/research/multichannel-outreach.md, not built.
Brand
Assets from Achraf are in public/brand (served) and docs/brand (reference). Palette: burgundy #391c25, ivory #f6f1e8, vermilion #d94a38. Headings use Outfit, UI text Geist, margin notes Caveat.
