Efficore (Mira)
Category: Project Status: Active (domain: mira.energy) Active development period: June–September 2024 Last updated: 2026-04-06
Overview
Efficore is a unified energy optimization platform for data centers, co-founded by Jack and Kevin Zhang. The company’s public domain is mira.energy.
Jack leads Efficore’s software and decision-making systems. Kevin brings deep expertise in energy systems and data center infrastructure — previously involved with the Northwestern Energy and Sustainability Club (NESC) and Q House.
The summer 2024 period (June–September) shows intensive weekly team syncs in Notion — 14 logged “Mira Meetings” — suggesting the core product and architecture was being built out during this period.

What Was Mira?
Based on available signals: - The final meeting is labeled “After Pylon” — Pylon is an AI customer support tool (YC company); possibly Mira evaluated or integrated Pylon - The project had a structured meeting cadence with a co-founder/collaborator named “Jamie” (per the meeting source field “Jamie” for all Mira meetings) - The meetings ran at 2–3x per week intensity in August, suggesting a crunch period
Significance
Mira occupies a significant gap in the archive — the entire summer of 2024, concurrent with the Berkeley AI Hackathon (June 29) and the Japan Trip 2024 planning. It likely represents either a previous startup Jack was involved with that wound down before he pivoted to Agentdex, or a parallel collaboration that influenced the AgentDex direction.
The Berkeley AI Hackathon Top 15 win in June 2024 (from Jack’s website) may have been Mira-related or AgentDex’s precursor.
