What to Do When Your CTO Leaves
When your CTO leaves, put someone in charge of protecting delivery, access and spending. A clear handover keeps the business running while you choose the right replacement.
Identify what depends on the departing CTO personally, from supplier relationships to system access and spending approvals.
Your first-week plan when a CTO leaves
Use this as a working list with your management team. Assign each action to someone by name and agree a completion date.
- Appoint the decision-makerOwner: Chief executive
Name the person who approves spending, sets priorities and handles urgent decisions. Tell staff and suppliers who to contact.
- Confirm company accessOwner: Technical lead
Check critical systems, hosting, domains, code, backups and account recovery. Ensure authorised staff can take over without relying on personal accounts or phones. Coordinate access changes with the departure.
- Record the next month’s commitmentsOwner: Departing CTO and delivery leads
List deadlines, incidents and pending decisions. Give each an owner and next action, then agree what continues and what can wait.
- Check spending and renewalsOwner: Finance lead
Review invoices, renewals and promised work. Confirm what is authorised and who can approve changes.
- Test the handoverOwner: Incoming lead
Ask the receiving team to demonstrate a routine task, such as releasing a change or escalating a fault. Assign an owner to each knowledge gap.
If the CTO has already left, work through the same list with the team and suppliers. Prioritise anything that can interrupt service, delay customer delivery or leave a payment decision unattended.
Choose interim or fractional CTO cover for the workload
Use interim cover when the business needs daily leadership: a major delivery is at risk, the team needs close management or several critical decisions are unresolved. Give the interim leader responsibility for the agreed priorities, budget and delivery, with clear approval limits.
Fractional CTO support fits when capable people are running day-to-day operations and the gap is in senior decisions, supplier management and coordination. Typical engagements use two to four days a month. A departure with substantial handover work can need more time at the start.
Agree the initial tasks, availability and decision-making authority before choosing the number of days. At Seneca, we take ownership of the agreed work, lead the team and suppliers, and report progress against the business priorities.
Our indicative rate is £1,100 per day ex VAT. Two days a month is £2,200 per month ex VAT. There is no standard minimum commitment: scope, time and terms are agreed individually. Longer-term discounts are agreed separately. See our technology leadership pricing.
Build the replacement CTO brief from the handover
Use the first review to define what the next leader must deliver. Separate the work the business needs now from the responsibilities the previous CTO accumulated over time.
- Business outcomes: which delivery deadlines, operating costs or service problems must improve?
- Responsibilities: does the role cover product engineering, internal systems, suppliers, security or all four?
- Authority and resources: what can the CTO decide, what needs board approval and who will do the work?
- Time commitment: is there enough continuing leadership work for a full-time role, or does fractional support fit the operation?
We can turn that brief into practical interview questions, assess candidates and manage the handover to the appointed leader. The replacement should inherit an agreed plan, a clear budget and named owners for ongoing work.
Manage a CTO departure during fundraising
Tell investors who owns technology decisions and whether delivery dates or budgets have changed. Keep the roadmap and data-room answers consistent with that plan.
Barry Weaver has raised over £200m, from EIS and VC through to large private equity. We manage the technology work behind the investment case.
Questions about replacing a departing CTO
What should I do first when my CTO leaves?
Appoint a lead with authority to keep work moving and approve urgent decisions. Use the first-week checklist above to organise the handover.
Do I need to hire a permanent CTO immediately?
No. Put accountable cover in place while you establish the workload and the role you need to fill.
What should a CTO handover include?
Record access, commitments, costs, risks and owners. A handover is complete when the receiving team can use those records to run the operation.
Can an interim CTO help recruit the replacement?
Yes. They can define the brief, assess candidates and manage the transition to the appointed leader.
Arrange leadership cover for a CTO departure
Tell us when your CTO is leaving and what needs to keep moving. We will agree the immediate priorities, the responsibilities we take on and the time and cost of the cover.
