Technical & financial advisory · Carlsbad, CA

Day one is the idea. Day two is everything that comes after.

Senior technology and finance leadership for tech companies at every stage after the idea. We help you build it right, or rebuild what was built too fast, with fractional CTO and CFO roles and hands-on work across cloud, software, AI and finance strategy.

DAY ONE

The idea.

DAY TWO

  • Build it.
  • Fix it.
  • Scale it.
  • Fund it.
  • Sell it.

What we do

Two disciplines. One bench.

Most startups hire technology and finance help separately, and the two rarely talk to each other. We bring both under one roof, so your architecture decisions, burn rate and fundraising story stay aligned.

Technology

Senior engineering judgment for the decisions that are expensive to get wrong.

  • Infrastructure & IT overhaulsRe-architecting cloud and internal systems built for speed, so they're ready to scale.
  • Cloud architectureDesign, migration, cost and reliability on AWS, Azure and GCP.
  • Software engineeringArchitecture reviews, delivery practices and hands-on build support.
  • AI transformation & enablementFinding the AI use cases that pay off, then shipping them responsibly.

Finance

  • Planning & forecastingBudgets, runway models and scenario planning you can act on.
  • Fundraising & investor readinessFinancial models, data rooms and reporting investors trust.
  • Unit economics & growthPricing, margins and the metrics that show where growth pays off.
  • Finance systemsChoosing and setting up the tools and reporting that scale with you.

M&A DUE DILIGENCE · FOR ACQUIRERS

Know exactly what you're buying.

We investigate and validate an acquisition target's financials and technology side by side: earnings, controls, architecture, security, team and technical debt. You get one clear picture of risk and value before you commit.

How our diligence works

Fractional leadership

An executive seat at the table, sized to your stage.

A fractional CTO or CFO joins your leadership team part-time: owning strategy, building process and mentoring your people, at a fraction of a full-time executive's cost.

Financial clarity from your first hire to your next round.

How we work

Steady hands, clear handoffs.

  1. 01

    Assess

    We start with a focused review of your technology, finances and goals, and tell you plainly what matters most right now.

  2. 02

    Build

    We work alongside your team to put the right architecture, processes and financial systems in place.

  3. 03

    Scale

    As you grow, we stay on as fractional leaders, or help you hire full-time leaders and hand off cleanly.

Who we work with

From first build to next stage.

We work with tech companies at every point after the idea, from founders building their first product to later-stage startups that moved fast and now need the rigor to scale what they built.

  • —Later-stage startups hitting their limits, whose infrastructure, systems and processes were built for speed and now need to scale.
  • —Founders without a technical co-founder who need someone to own architecture and the engineering team.
  • —Companies preparing to raise or be acquired who need investor-ready financials and systems that hold up under diligence.
  • —Companies adopting AI who want practical results, not experiments that stall.
