Quick Facts
AccessGrid has raised $4.4 million in seed funding to turn smartphones into secure, universal digital keys for access control.
The Miami-based digital keys startup was founded by Auston Bunsen and Nathali Amaro, combining software and product design expertise.
Its technology issues encrypted credentials directly to Apple Wallet and Google Wallet, eliminating the need for separate keycards or fobs.
The system functions even when a smartphone is locked or out of battery, supporting access through connected wearables like Apple Watch.
Investors in the round include Harlem Capital, Spice Capital, Exceptional Capital, CEAS Investments, Ex Ante, Third Sphere, and HF0.
AccessGrid aims to replace outdated access infrastructure that relies on cloneable or easily compromised physical cards.
The company plans to expand beyond Florida, scaling partnerships with property operators, OEMs, and potentially automotive partners.
The funding marks a strong push toward digital-first identity and access management within the physical security market.
