Meet our Founder

Justin Burke is an early-stage go-to-market builder who helps founders turn uncertainty into clear market signal and a repeatable growth engine. He’s been an early GTM leader across multiple venture-backed startups, including one that reached unicorn status, and is known for a warm, steady approach that combines sharp diagnosis with hands-on execution.

Working at the first three startups he helped build taught Justin a simple truth: the details change, but the core GTM bottlenecks don’t. ICP drift, fuzzy positioning, inconsistent pipeline, and missing operating cadence show up in nearly every company. His work is about finding the constraint quickly, aligning story and motion, and building systems that compound beyond the initial push.

Justin created Luminal to bring other builders like him into founders’ corners.

People who’ve built the engine, not just talked about it. Luminal brings experienced GTM leaders across sales, marketing, RevOps, partnerships, and solution consulting, supported by automation and AI to create real leverage.

We are your plug-in GTM team

Fractional CMO/CRO-level leadership to set the plan plus hands-on builders to engineer and execute the system (positioning → pipeline → conversion → retention) until it becomes a repeatable revenue engine.

Capital-efficient growth

Experienced GTM leaders + builders without the headcount gamble, optimized for today’s efficiency-minded market (burn multiple, CAC payback, Rule of 40).

Revenue accountability

Bespoke, tested, full-funnel build-out and operation that drives a qualified pipeline and ARR — clear and reliable for investors, boards, and your own sanity.

Investor-ready traction

Clear pipeline growth and consistent deal wins. Plus clean metrics and a tight story you can take straight into fundraising (or board updates).
