As answered by people managing DevFinanceTools and LeadReef.
LeadReef's answer:
Most lead tools hand you a list and stop. LeadReef goes one step further and builds the thing you are selling. Point it at a city and a niche and it returns local businesses whose websites are broken, outdated or missing, scores each one by how likely they are to buy, and generates a working prototype of the site you would build them. You show up to the conversation with a result on screen instead of a description of one.
LeadReef's answer:
Three things. First, scoring: every lead arrives with a 0–100 opportunity score across visual quality, mobile experience, SEO and abandonment signals, so you spend your evening on the businesses that will actually buy. Second, the prototype: the part of the pitch that normally costs you an hour per lead is generated for you. Third, ownership: LeadReef writes the outreach but never sends it. Nothing leaves a shared pool of domains, so your sending reputation and your relationship with the client remain yours.
LeadReef's answer:
Freelance web designers and developers, small web agencies, and side-hustlers who sell websites to local businesses. Usually teams of one to three, selling projects in the few-hundred to few-thousand range, who spend far more time finding the next client than building the site once it is sold.
LeadReef's answer:
LeadReef started from an observation: building a small business website stopped being the hard part years ago. Finding the business that needs one, proving to them that it matters, and getting a reply — that is the actual work. The first version was a script that swept one city and flagged restaurants with no mobile site. Everything since has gone into turning that into something a freelancer can run before their first coffee.
