“A string of bright beads of sunlight, breaking through the valleys along the moon’s rim.”

— Francis Baily, 1836

Origin

Who is Baily?

Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.

He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.

That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.

Baily was a businessman before he was a scientist. That’s our vibe too.

Questions LA homeowners actually ask

Pasadena gunite pool-and-spa builds run $91.5K-$488K in 2026 — a Premium-tier submarket on the $75K-$400K LA baseline. Gunite is $116K-$195K for a 15x30 basic and $244K-$488K for 20x40 luxury with Baja shelf, beach entry, and attached spa. Gunite pricing is $75-$225/sqft of water surface. Fiberglass shell-only runs $61K-$183K. Vinyl liner is rare in the LA market.
Pasadena Building & Safety issues the main pool building permit in Pasadena, with separate electrical, plumbing, and gas sub-permits on top — the gas permit covers the heater line. Deep-end excavation over 5 feet requires a PE-stamped structural sheet. Pasadena hillside parcels also need a geotechnical report for slope stability before Pasadena Building & Safety will release the structural sheet. Plan-check runs 8-12 weeks for a standard residential gunite pool.
The federal Virginia Graeme Baker (VGB) Act plus California AB 1020 require every Pasadena pool drain to be anti-entrapment compliant — either dual drains with at least 3 feet of separation, or a single drain protected by a suction-vacuum release system (SVRS). Drain covers carry ASME A112.19.8 certification. The plumbing sub-permit inspection verifies VGB compliance before the pool is allowed to fill.
Pasadena hillside pools need a geotechnical report before design — Pasadena Building & Safety wants slope stability and soil-bearing data. The gunite pool shell doubles as a retaining element on steep lots, so the structural engineer ties it into the hillside with deepened footings. A hydrostatic relief valve in the main drain lets groundwater escape during empty/refill without floating the shell. Hillside builds add 30-60% to schedule.
