How you find contractors, by the work they’ve actually done near you.
This is the first chapter of The Digital City — a series that
explains, in plain terms, how Boostt turns the records a city publishes
every day into a real, navigable map of the people who actually work
there. No ads, no self-reported listings, no sponsored pins. Just the
public record, mapped.
This chapter: every time a contractor does legal construction
work in a US city, a permit is filed naming the contractor and the
street address of the job. Boostt reads those permits, figures out
what kind of work they describe, and attaches each job to the
contractor who did it. Over time, every contractor ends up with a map
of their real jobs — not their registered office, not a marketing
brochure, just the actual addresses where they've actually worked.
So when you search for a plumber near your home, you don't get
plumbers whose office happens to be nearby. You get plumbers who have
actually repaired sewers on your block, with dates and distances
as proof. It's the word-of-mouth question — “who has actually
worked around here?” — answered from the public record at
city scale.

01
A city, rebuilt from its own public record.
Every US city publishes records describing work that actually
happened: building permits, business licenses, property transfers,
professional licenses. When you pin them on a map, the city
appears — not as a directory of ads, but as a live picture of who
is actually working where. Every pin is a real event at a
real address, published by the city itself. Nothing is
fabricated. This chapter walks you from those raw records all the
way to the search that puts them to work.

Every pin is a real event at a real address. Nothing fabricated.
02
Who has actually worked on your block.
Every other contractor directory — Yelp, Angi, HomeAdvisor —
ranks contractors by where their office is. Office addresses are
usually meaningless: a home address, a PO box, an
accountant's office. It tells you nothing about whether that
contractor has ever worked on your street. Boostt ranks by where
contractors have actually done the work, using the real
permit addresses as proof. Five jobs within a mile of you beats
a fancy listing every time.

Realtors, creators, contractors — all on the same map.
Boostt doesn't keep separate databases for each kind of
professional. A licensed realtor, a TikTok creator, and a
contractor named on a building permit all appear on the same
map, in the same format. What differs is where each one came
from — state registries, city permits, social platforms. The
source is always visible, so you can always see why
someone appears on the map.

What anyone can see, and what signing in unlocks.
Anyone visiting the map sees what's already public record —
names, addresses, trades, ratings. Contact information (email,
phone, website, social profiles) is only shown to signed-in
users. This isn't a policy wrapped around the data; the
database itself is set up so the public map cannot
return contact columns. There is no version of the map that
leaks them, because the part of the system that serves the
public map doesn't have permission to read them.
