Consulting & Fractional CTO

Sometimes you don't need a build team — you need conviction. We provide architecture and code reviews, AI-readiness assessments, technical due diligence for investors, and fractional CTO leadership for teams between technical leaders.

Sometimes you don't need another team. You need a senior engineer who has shipped before, looking at your specific problem, telling you the truth. That is what this service is: conviction on demand — architecture reviews, technical due diligence, AI-readiness assessments, and fractional CTO engagements from the same senior bench that runs our builds.

When you need conviction, not headcount

Most technical decisions fail before any code is written. The wrong architecture gets approved because nobody in the room could challenge it. An acquisition closes on a codebase nobody actually read. An AI initiative launches without an evaluation plan and quietly dies six months later.

Hiring a full team to answer a question is the expensive way to get it wrong. We sell the answer instead:

  • Architecture reviews. We read your system the way we'd read our own before a launch: failure modes, scaling ceilings, security boundaries, cost trajectory. You get specific findings, not a maturity-model slide.
  • Code reviews. Line-level, honest, prioritized. We separate "this will hurt you in production" from "this is stylistic" — most reviews confuse the two.
  • AI-readiness. Where AI genuinely fits your product and operations, where it doesn't, and what your data and evaluation infrastructure need to look like before you spend money. We build AI systems for a living, which is exactly why we'll tell you when you don't need one.

We're candid about scope: if the answer to your question is "don't build this," we'll say so in week one and you'll pay for a week, not a quarter.

Reviews & due diligence

For investors and acquirers, we run technical due diligence on target companies: codebase quality, architecture debt, team dependencies, infrastructure cost reality, security posture, and — increasingly — whether claimed AI capabilities are real or a demo wrapped around an API key.

Output is board-readable. Findings ranked by severity, remediation cost estimated in engineer-months, and a plain-language summary a partner can read in ten minutes. The technical appendix is there for whoever needs to go deeper. If you're on the other side of the table — evaluating a build partner rather than a target — start with our software partner evaluation scorecard; it's the rubric we'd want used on us.

We operate under NDA on request and handle all materials with GDPR-compliant data practices. Diligence for US and EU deals gets the regulatory framing each side actually needs — EU AI Act and DORA exposure on one side, GENIUS Act positioning on the other.

Fractional CTO

For companies between "founder writing code" and "full-time CTO hire," we provide the role fractionally: a senior engineer who owns your technical direction for a defined slice of the week.

  • Architecture and vendor decisions with written rationale
  • Hiring support: role definitions, technical interviews, offer calibration
  • Board and investor communication — translating engineering reality into decisions
  • Roadmap pressure-testing against what your team can actually ship

Every fractional engagement runs on the same operating discipline as our delivery work: weekly demos or written updates, decisions documented, nothing living in one person's head. No lock-in — every artifact we produce is designed so your next hire can pick it up cold. Full IP assignment from day one; the goal of a good fractional CTO is to make themselves replaceable.

What you walk away with

Every engagement ends with artifacts, not vibes:

  • A written assessment with findings ranked by severity and cost to fix
  • Architecture diagrams and decision records your team owns outright
  • A prioritized 90-day technical plan
  • A board-readable summary — one page, plain language, defensible

Engagements start with a fixed-fee discovery sprint, so the cost of finding out is known before you commit.

Frequently asked
What does a technical due-diligence engagement look like?
Fixed fee, 2–4 weeks: we review architecture, code quality, security posture, team practices, and scaling risks, and deliver a report your investment committee can read.
How does fractional CTO work?
A senior Binari engineer takes defined leadership responsibility — roadmap, hiring, architecture decisions — for a set number of days per week, until you hire full-time or the phase passes.
Can consulting turn into a build engagement?
Often it does — the review de-risks the build. But the report is written to be useful whoever builds next; there's no lock-in by design.
