The BuiltWith alternative built for agencies who pitch local businesses.
BuiltWith tracks which technologies websites use and sells lead lists of sites by technology, with free single-site lookups and paid plans for lists and API access. Larzo starts where a list ends: it audits every business, ranks it by real opportunity with evidence, and writes the outreach.
