“It can be very difficult to find a software studio that can fully integrate with internal teams and own the project and responsibilities like Cookielab does. To know we can rely on them is important for us, and helps us every day.”

What we handle

From strategy to execution

01

Too many decisions, too little clarity

We step in and help sort product and technology priorities. Architecture decisions, build vs buy, tech stack selection. All aligned with where the business needs to go.

02

Team growing faster than structure

We help design and lead the engineering organization. Hiring plan, technical interviews, onboarding, culture. We build the team that stays after we leave.

03

Delivery pressure after fundraising

We bring discipline. Realistic plans, clear sprint structure, progress monitoring. Your product ships on time because someone owns the process.

04

Tough questions from the board

Technical due diligence preparation, board presentations, investor communications. We have been through multiple funding rounds ourselves.

How the engagement works

01

Assess

We review the current reality. The team, product, roadmap, risks, and expectations from founders and investors.

Week 1
02

Stabilize

We support founders by taking ownership of day-to-day technology leadership and execution, while keeping them involved in key decisions.

03

Scale

We help build structures that scale. Teams, leadership layers, processes, and documentation so growth does not depend on a single person.

Frequently asked questions

How is this different from hiring a consultant?
Consultants advise. We lead. We attend your standups, make architecture decisions, hire engineers, and take accountability for delivery. We are your CTO.
How much time does the CTO spend with us?
From 2 days a week to full-time. Most startups start full-time and taper down as we build their internal team.
What happens when we hire our own CTO?
That is the goal. We help you hire them, onboard them, and transfer knowledge. We typically stay for a 1-month handoff overlap to make sure the transition is smooth.
Can you also build the product?
Yes. We can lead your existing team, augment it with our engineers, or build the entire product. Most engagements combine CTO leadership with a Cookielab development team.
What if our CTO needs are temporary?
That is exactly what this service is for. Whether it is 3 months of crisis management or 12 months of building from scratch, we scale to your needs.
