Fractional CTO for funded teams whose releases slip

You raised, sales are working and the team is past fifteen engineers, yet releases keep slipping. The missing piece is usually engineering management, not more engineers: someone who owns release dates, technical risk and who decides what gets built next. A fractional CTO maps who decides what, sets a delivery rhythm, and either hires the leader you need or runs engineering until one is in place.

From our experts

Selected cases from these experts’ profiles.

A business that sells well but can't ship

Sales and product are strong, the CEO and CFO are capable, but there is no engineering leadership. The product lead assigns tasks to about fifteen engineers, technical leaders don't last, and releases slip. The expert starts with careful interviews (people under pressure don't need to hear "it's all bad"), then sets up who decides what, the delivery process, and either hires a CTO or acts as one.

You get

An ownership map, a delivery rhythm and a hiring plan.

An investor's portfolio company: "the tech looks wrong"

An investor sees a portfolio company that has raised a round, and its technology looks wrong. The founders say the problem is not the technology but management: predictability, risk and who decides what. One of our experts comes in at due-diligence stage, then either sets up the missing skills and steps away, or steps in and runs engineering for a while.

Delivery health check for a fintech team

Releases slip and nobody can say why. This manager would review the backlog, the sprint cadence, the definition of done, the release process and the CI/CD gates.

You get

A short written assessment with a prioritized list of process changes. Technical architecture questions go to a senior architect.

"We need a full rewrite": the senior answer

The team tells the founders the product must be rewritten before anything new can ship. The expert reviews what can change in place and finds the smallest path to the next feature within the current system, keeping a rewrite as a last resort with a stated cost.

You get

The next feature's path without a rewrite, plus an honest cost of the rewrite if it's still needed.

Planning with deadlines and flexible scope instead of estimates

A team keeps missing estimates and spends too much time producing them.

Switch date-bound work to fixed time and budget with flexible scope: list features as independently shippable pieces, prioritize them, make sure CD is in place, ship the most important first and keep the system working at all times.

You get

A reworked planning process with prioritized feature slices and a check-in rhythm.

Building engineering teams, including across regions

One of our experts has built several engineering teams, for their own companies and for others, including teams spread across several regions and time zones. They set up roles, hiring and delivery so the team runs without them in every decision.

Questions buyers ask

Our releases keep slipping after we raised. Do we need more engineers?+
Usually not first. When a funded team keeps missing dates, the cause is more often that nobody owns engineering: release dates, technical risk and who decides what the team works on next. More engineers in an unowned process make the queue longer, not faster.
Our CTO left. Do we have to hire a replacement straight away?+
Not before you know what the role has to fix. A fractional CTO can run engineering for a while, map who decides what and set a delivery rhythm, then help you hire against a defined role instead of in a hurry.
What does technical due diligence actually check?+
Whether what the company told investors is true. A due-diligence expert checks the claims made in negotiations against primary sources: the code repositories, documents and real transactions. The answer is close to yes or no: accurate, not accurate, or sincerely mistaken. Recommendations on what to fix are a separate job, an audit. One of Invental's experts does this for investors before they commit.

How it works

  1. Tell us what you need — the repo or system, the question, and the deadline.
  2. We match an expert to your code or system, with a second reviewer where it helps.
  3. Scoped work, contracted through Invental — review per pull request, a fixed-scope audit or architecture review, or ongoing capacity.
