Transforming Access Control Through Advanced Digital Key Management

Innovations in Secure Entry: From Blockchain Foundations to Smart Solutions

Auston Bunsen’s journey began after his blockchain infrastructure company, QuickNode, experienced rapid growth.Established in 2017, QuickNode raised over $100 million in funding, positioning itself as a leader within the blockchain growth ecosystem.

Building on this success, Bunsen turned his attention toward revolutionizing everyday security practices. He imagined a world where unlocking doors would be as intuitive and effortless as using a smartphone. This vision led him to collaborate with Apple representatives to enhance Apple Wallet’s functionality by integrating physical access capabilities directly into the platform.

The Emergence of AccessGrid: Pioneering Digital Key Ecosystems

After departing from quicknode in late 2023, Bunsen committed fully to creating AccessGrid, an API-driven platform that enables businesses to manage digital keys seamlessly through both Apple and Google wallet systems. Designed for maximum convenience,AccessGrid operates even when devices are locked or powered down and offers smooth synchronization with wearable technology like the Apple Watch.

Launched officially in April 2025, AccessGrid recently secured $4.4 million during its seed funding round led by Harlem Capital. These funds will accelerate enhancements focused on bolstering security protocols and expanding into emerging sectors such as automotive access control solutions.

The Limitations of Traditional Access Control Technologies

Bunsen points out that many current access control infrastructures rely heavily on outdated technologies dating back decades. These legacy systems often depend on localized hardware disconnected from cloud services or utilize unencrypted dialogue channels vulnerable to cyberattacks.

“The industry is overdue for a extensive upgrade,” he asserts. “AccessGrid replaces fragile physical ID cards and insecure legacy methods with encrypted digital credentials that cannot be duplicated and can be instantly revoked via cloud management.”

Implementing State-of-the-Art Security Protocols

Aware of the cybersecurity challenges inherent in managing digital keys, AccessGrid incorporates military-grade encryption alongside dual-layer cryptographic techniques. Multi-factor authentication protects all server communications while adhering strictly to industry-standard cybersecurity frameworks-ensuring robust defense against unauthorized intrusions.

An API-First Platform Empowering Developers Without hardware Constraints

Differentiating itself from competitors such as SwiftConnect and Sharry-which often bundle hardware middleware or require service contracts-AccessGrid functions exclusively as an API-first platform without selling proprietary hardware or end-user applications.

This developer-centric model grants software creators flexible tools tailored specifically for embedding secure digital key functionalities into their own products without reliance on outdated infrastructure or vendor lock-in scenarios common within traditional ecosystems.

sustaining Growth While prioritizing User experience Over Fundraising Distractions

• Bunsen now leads this venture independently; unlike his previous startup experience at QuickNode where he co-founded alongside partners.
• The recent seed round attracted investors connected through longstanding relationships including Harlem Capital’s Henri Pierre-Jacques along with supporters from Remarkable Capital and Spice Capital who previously backed Bunsen’s projects.
• Participation in accelerator programs like HF0 provided essential early-stage financial support.
• This network has been vital while allowing minimal disruption caused by fundraising activities.

“Our primary focus remains delivering exceptional customer value; fundraising is merely a necessary step-not our main objective.”

A Future Where Mobile Wallets Replace Physical Keys Everywhere

Bunsen envisions converting every U.S.-based access control reader into smart entry points compatible with mobile wallets within the next several years:

“Picture never needing traditional keys again because your smartphone automatically unlocks doors when you approach.”

This ambition extends beyond commercial buildings-soon encompassing vehicles and other secured environments-to create seamless entry experiences that improve safety while simplifying daily routines for individuals and automated systems alike.
