Lasso

Lasso is a B2B contact and company data platform from Lasso A.I., Inc., built around a network that the company says learns contacts continuously rather than relying on a static database that decays. Its tagline is "Databases decay. Networks learn." Users search the network for companies and contacts that match their criteria, save the result as a named Lasso, and continue or expand it later. The product is aimed at sales, marketing and sponsorship teams building prospect lists. Searches can target signals such as growth indicators or recent leadership hires, including marketing and sponsorship leaders hired in the last 180 days, and results can be enriched with email addresses, phone numbers, company details and LinkedIn data. Company enrichment draws on Lasso's own company information and on Clearbit. Users can upload contact and company lists by CSV, maintain company and contact exclusion lists, organize work into campaigns, generate emails, and connect CRM accounts through API keys for data syncing. Lasso works on a credit system. The app shows enrichment costs such as 1 credit for up to 10 results for Lasso company information and 5 credits per result for Clearbit enrichment, with credit top ups, an optional monthly top up and subscription plans managed inside the account. Plan prices are not published on the public site. The public site currently presents Lasso as a private beta, showing only its tagline and a sign in screen, so access appears to be limited to invited users for now.
