Greater Bay Technology Public-Source Startup Diligence Report
The public case rests on XFC battery performance claims, GAC ecosystem commercialization, strategic investors, a $1.26B CB tracker valuation, and patent filings. Diligence should prove repeatable non-GAC revenue, pack safety/reliability, manufacturing economics, current financing terms, and PRC legal/EHS/IP cleanliness.
Greater Bay Technology Public-Source Startup Diligence Report
Eligible for a public-source diligence report: CB Insights lists Greater Bay Technology as a $1.26B private unicorn, CB profile says Alive, and May 2026 Chinese financing news indicates ongoing private B-round activity. The company is a GAC-incubated Guangzhou EV fast-charging battery company with visible GAC/AION commercialization and patent activity, but financials, customer concentration, cap table, technical validation, and legal/regulatory checks require private diligence.
Audited financials, revenue by customer/product/channel, backlog, AR aging, margin, warranty reserves, and cash runway are not public.
Diligence request: Require audited financials, monthly accounts, revenue/gross-margin schedules, cash runway, backlog, AR aging, and warranty reserves.
Publicly named commercialization evidence is concentrated in GAC AION examples and GAC incubation; non-GAC OEMs are unnamed and revenue concentration is not public.
Diligence request: Request customer revenue schedule, OEM contracts, volumes by model, non-GAC customer references, and GAC agreement terms.
Fast charging and Phoenix claims require independent validation and production-yield evidence.
Diligence request: Commission technical diligence on lab tests, cycle life, low-temperature charging, safety, yield, warranty claims, and OEM acceptance.
CB shows Series A/$157.15M total raised, while Sina reports a newer B round with undisclosed amount; ownership, rights, debt, valuation, and dilution are not public.
Diligence request: Request current fully diluted cap table, B-round documents, investor rights, debt schedules, and valuation support.
Patent filings are public, but registry/court/admin-penalty access was limited; IP assignments, licenses, FTO, EHS permits, litigation, and regulatory matters are not publicly verified.
Diligence request: Engage PRC counsel and require legal/IP schedules, assignments, licenses, FTO analysis, and product-safety certifications.
High-power fast charging and storage products can create safety, thermal, warranty, recall, and product-liability exposure; claims history/insurance are not public.
Diligence request: Request safety certifications, abuse/thermal tests, field failure and warranty data, recalls, EHS permits, insurance, and indemnity terms.
CB identifies fast-charging competitors; without pricing/cost data, defensibility and margins are unclear.
Diligence request: Obtain win/loss data, competitor benchmarks, pricing history, cost curves, and OEM qualification comparisons.
Official pages, Chinese registry/commercial databases, and Crunchbase were blocked, timed out, geoblocked, or incomplete.
Diligence request: Repeat source collection with local PRC access, official materials, management interviews, and registry exports.
Public sources verify unicorn/funding/investor signals but not financial statements, forecasts, cap table, tax, revenue, backlog, or unit economics.
