Role at Efficore

Kevin co-founded Efficore with Jack. Efficore is a unified energy optimization platform for data centers — Kevin brings deep expertise in energy systems and data center infrastructure, translating complex energy domain knowledge into practical solutions. Jack leads Efficore’s software and decision-making systems.

The company’s domain is mira.energy. Kevin’s background includes Northwestern Energy and Sustainability Club (NESC) and Q House — the same Q House that Jack co-organized in 2023, which is how their paths likely first crossed.

Ces 2025

Kevin was a key part of Jack’s CES 2025 trip to Las Vegas (January 6-10, 2025). The CES People List in Notion was organized around their delegation, which also included Ryan Kim and Lucas Jaggernauth.

Meetings

Kevin appears as the creator of several Granola meeting notes — suggesting he was also using the same meeting notes infrastructure as Jack during their collaborative period (early-mid 2025).

Mira

Between June-September 2024, Notion contains “Mira Meetings” — recurring syncs with someone named Mira. These appear to be Kevin-related based on the meeting structure; The Mira meetings ran Jun–Sep 2024 as weekly team syncs.

Architecture and Product Discussions

A Notion page titled “Jack kevin architecture notion, product” (Jul 2025) captures a deep technical-product discussion between them. This kind of page is typical of serious co-founder-level conversation — not just execution updates but fundamental architecture decisions.
