As answered by people managing Settilo and CodePen.
Settilo'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.
