Luminik helps B2B sales and marketing teams turn the events they attend (RSA, Black Hat, Money20/20, fintech summits) into pipeline. Bootstrapped, live with paying customers. I am the only full-time person on the team.

A couple of outcomes from our customers:

• A Series C cybersecurity company attributed $2.4M of pipeline to RSA, Black Hat, and one regional summit, sourced and sequenced through Luminik.
• A Series A identity verification company attributed $2M across fifteen fintech events in the second half of 2025.

• Aura at Bain Founder's Studio: a PE due-diligence platform. Took it from 0 to $3.6M ARR in 18 months. The team grew from five engineers to thirty-three over the same window.
• Mainteny: co-founded. $2.7M seed, European field-services SaaS.
• SnowOptix: Snowflake cost-optimisation tool. Bootstrapped, used by a top-3 global consulting firm.
• BlueJeans (started 2014): backend engineer on the video conferencing team. Where I first watched a real engineering org coordinate, before I had to do it myself with no team to lean on.

A small team of agents, named after Batman side-characters, handles the recurring engineering work for Luminik. Each one is shaped around a specific job and operates under a contract for what it can decide alone and what comes through me.

The stack is open source: Hermes Agent (Nous Research) drives the orchestration loop on free Gemini Flash, Claude Code handles real coding work via ACP, and a local gbrain (Garry Tan) instance holds a 107-page knowledge base of specs and CLAUDE.md files queryable from anywhere on the box. The whole thing runs on a Mac Mini.

Full write-up: Building Toward a Team of Digital Employees on a Mac Mini.

While setting up the agent stack, three things were broken or badly defaulted in tools I depended on. All in public trackers.

• Hermes Agent #12251. Gemini auth regression after the project switched Google AI Studio auth from Bearer to x-goog-api-key. I isolated the repro on the live /v1beta/openai endpoint, and the maintainer landed a clean superseding fix the same day. Merged.
• Hermes Agent #12224. The WhatsApp PLATFORM_HINT told every model "WhatsApp does not render markdown" and silently overrode persona files. WhatsApp does support *bold*, _italic_, ~strike~, code, fenced blocks, and bullet lists. Open.
• gbrain #89. v0.12.0 hardcodes OpenAI embeddings, which silently undoes the zero-marginal-cost story for anyone running Gemini elsewhere. Confirmed the community Gemini-embedding patch on the same 107-page corpus and left a +1 with a repro. Open.

Long-form on solo building, agent infrastructure, encoding judgment for AI tooling, and what coordination looks like when you are the team.

• Building Toward a Team of Digital Employees on a Mac Mini. Hermes Agent + Claude Code via ACP + gbrain, three upstream bugs filed along the way.
• gstack, CLAUDE.md, and the Work That Frameworks Don't Cover. Where in-repo instruction files stop, and cross-session memory needs to start.
• What It Actually Costs to Build a Serious Product Alone in 2026. The cost structure of compressing a team into one desk.
• Building a $3.6M ARR Product Inside a Consulting Firm. The Aura story, five engineers to thirty-three.
