StackGap is a lead-list service that scans local business websites and emails you a CSV of the ones with no live chat widget installed, priced at $1.20 per lead. You name a niche and a city — dentists in Austin, law firms in Chicago, roofers in Leeds — and within 24 hours you receive one row per business containing its name, category, city and address, website, phone number, email where publicly listed, and the detected gap. It is a one-time purchase delivered by email, built for people who sell chat, live-support, or web services to local businesses.
What is StackGap?
StackGap is a lead-generation service that scans local business websites and returns only the businesses where no known chat widget was found. The input is a niche plus a city and a lead count; the output is a CSV with business name, category, city and address, website, phone number, email (when publicly listed), and the chat-widget status of "none found." Orders are placed through the site's checkout and the list arrives by email within 24 hours, ready for a CRM or cold-email tool.
What makes StackGap stand out?
- Gap-based filtering — every site is loaded and checked for the scripts of known chat tools including Intercom, Tidio, Crisp, LiveChat, Chatbase, Drift, Zendesk and HubSpot chat; only sites where none are found make the list.
- Per-list pricing instead of seats — $1.20 per lead, 100 leads for $120, paid once with no subscription and no contract.
- 24-hour delivery — the completed CSV is sent to the email entered at checkout, so pitching can start the same day.
- Freshly built lists — each order is assembled from public business listings and the businesses' own websites rather than a stale database dump.
- Free bad-lead replacement — report an incorrect lead within 7 days and it is swapped at no cost; if the list cannot be delivered, the order is refunded.
- CRM-ready export — the CSV works with HubSpot, Apollo, Instantly, Lemlist, Google Sheets and any tool that accepts CSV.
- Order-specific scope — the lead-count slider shown on the page runs from 25 to 500 leads, so the niche and city can be changed for each new list.
Who should use StackGap?
- Chat widget and live-support vendors: get a list of local businesses in a target city that have no chat tool installed, and pitch the gap directly.
- Web design and conversion agencies: find local service businesses — dentists, plumbers, law firms, roofers, veterinarians, Shopify stores — already in a chosen metro, to pitch site improvements.
- Freelance cold-email consultants: buy a niche-and-city CSV and load it straight into Instantly or Lemlist for an outreach campaign.
- SaaS founders selling to local businesses: test a new vertical by ordering a small list in one city before scaling to other metros.
Use cases
- Chat-product sellers: order dentists in Austin, get a CSV of practices with no live chat, and send a first pitch the next day.
- Agencies expanding into a new city: request law firms in Chicago or roofers in Leeds to build a local prospect pipeline without manually searching Google Maps.
- Cold-email operators: import the delivered CSV into HubSpot, Apollo, Instantly, Lemlist or Google Sheets and start a sequence.
- Shopify-focused freelancers: target Shopify stores in a city that lack a chat widget, using the category column to filter them out of the list.

FAQ
What is included in each StackGap lead?
Each row contains the business name, category, city and address, website, phone number, and email when it is publicly listed, plus the gap detected. One CSV row equals one business.
How does StackGap know a business has no chat widget?
StackGap loads each website and checks it for the scripts of known chat tools such as Intercom, Tidio, Crisp, LiveChat, Chatbase, Drift and Zendesk. Only sites where none of those are found are added to your list.
How fast is delivery, and is it a subscription?
Lists are emailed as a CSV within 24 hours of payment. StackGap is not a subscription — you pay once per list and can return whenever you need a new niche or city.
What happens if a lead is wrong?
Report an incorrect lead within 7 days and StackGap replaces it free. If the list cannot be delivered at all, the order is refunded under the published refund policy.
Am I allowed to contact the businesses on the list?
The data comes from public business sources, but you are responsible for following outreach laws in your market, such as CAN-SPAM in the US or GDPR in the EU.
