Bixby Construction-tech startup using AI to speed up submittal review for general contractors: surfaces non-compliant products, cites sources, and cross-references hundreds of pages of specs/submittals in minutes. Pre-seed funding from Daybreak Capital Partners (lead) and Flybridge per independent sources. NOTE: Perceptive Ventures' own portfolio page lists this as a portfolio company, but independent sources (Crunchbase/PitchBook) name only Daybreak Capital Partners and Flybridge as investors — the Perceptive relationship is unconfirmed, flagged rather than asserted.
