Deal sourcing — how LamboApp screens 30+ brokers

Scrapes 30+ brokers on a schedule, normalizes the schema, deduplicates, hands each listing to the AI scorer.

Deal sourcing

LamboApp is a screener, not a listing site. It doesn't host the listings — it reads them from the sources that already exist and normalizes them into one feed.

The sources

Roughly 30+ business-for-sale brokers, updated on rolling schedules. The big ones:

  • BizBuySell — the largest general-purpose SMB marketplace.
  • Flippa — mostly digital/web/SaaS/apps.
  • Empire Flippers — vetted content sites and e-commerce.
  • Quiet Light — brokered digital businesses, higher end.
  • Website Closers — full-service brokered digital businesses.

Plus specialty brokers for laundromats, HVAC, dental practices, and other verticals.

The pipeline

  1. Scan — scheduled jobs pull each broker's public listing feed (or scrape the HTML index page where no feed exists).
  2. Normalize — every listing gets mapped to a shared schema: slug, asking_price, sde, revenue, industry, location, established, broker, listing_url.
  3. Deduplicate — the same business is often listed on multiple brokers. Dedup is keyed on domain + numeric fingerprint (asking price + SDE within a tolerance window).
  4. Score — every new listing goes to the AI scorer. See AI scoring.
  5. Publish — scored listings appear at /deal/<slug> on the landing site with the thesis, the red flags, and a link back to the original listing.

What you see as a user

On the landing site: a ranked deal feed, filtered by industry, SDE multiple, asking price, and geographic scope. Every deal links to:

  • The AI thesis (why this is worth looking at).
  • The red flags the AI caught.
  • The original listing on the broker's site (we don't compete with them — we drive traffic to them).

What we don't do

  • We don't scrape MLS/private deal networks. The scanner respects robots.txt and only reads public listings.
  • We don't broker deals. You reach out to the broker directly using the link on the listing.
  • We don't take a commission. The value is in the screening, not the transaction.
  • We don't republish full listing copy. The thesis is our own analysis; the raw listing content stays on the broker's site.

Data freshness

Most brokers get scanned every 8 hours. High-volume sources (BizBuySell, Flippa) get scanned more often. A listing typically appears in the LamboApp feed within a few hours of being posted upstream.
