ExtendsClass JSON GeneratorSettilo's answer:
Settilo analyzes the neighborhood, not the listing. While most real estate platforms focus on property details, Settilo surfaces the data that surrounds it — crime trends over time, school quality at the attendance-zone level, local economic trajectory, and housing value trends — pulled from authoritative public sources and presented in one place.
Settilo's answer:
Settilo is built exclusively for buyers, with no listing revenue, no agent relationships, and no incentive to obscure unfavorable data. Competitors l target institutional and B2B customers at $125–400/month. Settilo makes the same depth of neighborhood intelligence accessible to individual buyers at a consumer price point, with a comparison interface built around the actual decision: which neighborhood fits my priorities.
Settilo's answer:
Analysis-first home buyers — people relocating to an unfamiliar city, first-time buyers doing serious research, and anyone who wants to understand a neighborhood before committing to it. They're data-literate, often comparing 3–5 areas simultaneously, and frustrated by how scattered the relevant information is across government databases.
Settilo's answer:
Settilo was built by a team that went through the home-buying process and noticed that every useful data point required a different government website, inconsistent formats, and hours of manual work. The property data was easy to find. The neighborhood data — the part that determines long-term quality of life — wasn't. Settilo launched in March 2026 to fix that.
Settilo's answer:
Next.js, PostgreSQL with PostGIS for geospatial queries, US Census Bureau data (ACS), FBI UCR crime data, GreatSchools API, and Mapbox for geographic visualization.
