YieldStack's answer
AI integrations supporting the platform’s workflows.
GetBirthChart's answer:
Next.js, TypeScript, React, Python, FastAPI, Swiss Ephemeris, PostgreSQL, Redis, and AI language models for interpretation.
YieldStack's answer
YieldStack combines AI-assisted lender matching with hands-on commercial mortgage brokerage. Borrowers submit once, compare financing options, and work with a team that handles structuring, negotiation, and closing coordination. Borrowers approve lender outreach, with no upfront fees and a broker fee paid only at closing.
GetBirthChart's answer:
GetBirthChart separates deterministic chart calculation from AI interpretation. Planetary positions, houses, angles, and aspects are calculated first from birth data, then AI explains how those factors interact. If the birth time is unknown, time-dependent results are omitted rather than guessed.
YieldStack's answer
YieldStack helps borrowers evaluate the whole financing offer: rate, leverage, fees, reserves, prepayment terms, and closing requirements. Its platform organizes the process, while its brokerage team helps borrowers find suitable lenders and move the deal forward. One submission gives borrowers a coordinated financing process without an upfront brokerage fee.
GetBirthChart's answer:
GetBirthChart focuses on transparent calculations, clear handling of uncertain birth data, and interpretations that combine placements, houses, and aspects instead of treating each factor as an isolated personality trait. It also provides free chart tools and an open-source calculation engine.
YieldStack's answer
Commercial real estate investors, developers, operators, and mortgage brokers seeking bridge, DSCR, fix-and-flip, construction, multifamily, and permanent financing across the United States.
GetBirthChart's answer:
People who want to calculate and understand their birth chart, from beginners exploring their Sun, Moon, and Rising signs to users interested in aspects, houses, compatibility, synastry, and yearly transits.
YieldStack's answer
Rommin Adl and Daniel Chesney founded YieldStack to simplify commercial real estate financing. The platform brings deal preparation, lender matching, offer comparison, and closing coordination into one workflow, combining AI-assisted analysis with human brokerage expertise.
GetBirthChart's answer:
GetBirthChart was built around a simple idea: chart calculation and interpretation should be separate. The project began with a deterministic astrology engine using Swiss Ephemeris, then added a user-facing platform that turns structured chart data into clearer explanations and interactive tools.
