TRENDev
CTO advisory · Technology leadership · Product delivery

Your technology partner, from idea to scale.

For founders building a product, startups scaling their teams and investors assessing technology. TRENDev brings technical advice, CTO leadership and hands-on delivery to turn your next step into a clear plan and concrete work.

See CTO advisory plans

Engineering and CTO expertise spanning two-squad teams and organisations of approximately 90 engineers.

Technical support for your next step

Launch a product, scale an engineering organisation or assess a technology investment. We help you understand the choices, make a plan and bring in the expertise to move forward.

For founders

Turn a project into a product. Get support with technical feasibility, architecture, an MVP roadmap and implementation — whether you have an engineering team or are putting one together.

For growing startups

Keep product delivery moving as customers and teams grow. Strengthen your architecture, structure your engineering organisation and bring in leadership or delivery capacity for the next stage.

For investors

Get a clear technical view before an investment or during portfolio support. Assess the product, architecture, engineering organisation and delivery risks through technical due diligence, then define practical priorities with the founders.

Advice, leadership and delivery

A technical assessment for a specific question. Ongoing advice for recurring decisions. CTO leadership or a delivery team for work that needs execution. Each engagement has a clear scope; you can start with any of them.

Concrete work behind the expertise

Selected engagements illustrating the experience brought to TRENDev missions. Real constraints, specific work and documented scope — with client identities kept confidential.

Approximately 90 engineers · 10 squads

Moving from a single-tenant platform towards a multi-tenant, API-first model required both architectural choices and a delivery approach the board could assess.

  • Compared transformation scenarios for the board
  • Evaluated API gateway alternatives
  • Worked within the squad facing the greatest delivery constraints

10 engineers across two squads

Technology changes and a growing engineering organisation needed one coherent plan, from mobile and cloud architecture to hiring and executive reporting.

  • Technical audit and organisation design
  • Flutter-to-React Native and Azure-to-AWS transition work
  • Three-year roadmap, hiring plan and executive reporting

SaaS · Approximately 15 people · 100+ EC2 instances

A small SaaS organisation operated a service spread across more than 100 EC2 instances. The work connected service refactoring, a target SaaS architecture and disaster recovery planning.

  • Service audit and refactoring
  • Target architecture
  • Disaster recovery planning

Senior leadership. A delivery team shaped around the mission.

TRENDev combines a senior technical lead with trusted delivery partners who have worked together repeatedly. We agree the team, responsibilities and delivery milestones around your needs, alongside your own engineers.

Senior technical accountability

TRENDev provides technical direction and delivery governance, with clear decision ownership, responsibilities and reporting agreed for each mission.

A trusted delivery network

We assemble the capabilities the work requires through established delivery partnerships. The team and each partner’s responsibilities are agreed for the mission.

Scope agreed before work starts

Roles, responsibilities, capacity, fees and acceptance criteria are defined for each mission up front, with delivery governance to match.

Alongside your team

Work is planned around your existing engineers and suppliers, with clear hand-offs so your team can carry it forward.

Useful advice, with freedom over who delivers

Advice must stand on its own. If we propose a follow-on delivery engagement, we disclose that commercial interest and agree it separately.

  • Recommendations rest on evidence and include credible alternatives, including no change.
  • Any proposed delivery relationship, ours or a partner's, is disclosed.
  • Delivery is a separate scope, agreed and priced on its own.
  • You remain free to execute internally or choose another provider.

How we work

Understand the bottleneck, agree priorities, then put change into practice. In a delivery or Fractional CTO mission, we lead the agreed work; in advisory, your team owns execution.

Frequently Asked Questions

A few of the questions that come up most. The full knowledge base goes considerably deeper.

If your hardest open question is “how do we build this”, you need a strong lead developer. If it is “should we build this at all, and what does it commit us to”, you need CTO judgement.

Headcount alone does not answer this. Consider the complexity of the platform, the number of teams to coordinate and the decisions the business needs technology leadership to own.

For occasional decision support, an Advisor subscription may fit. For an operational leadership mandate, consider a Fractional CTO. If the need is implementation capacity, TRENDev can scope a delivery mission alongside your lead developer. A free consultation can help define which gap you actually need to fill.

Start with the mandate: what needs to be owned, what authority is required and how much continuity the organisation needs.

A full-time CTO makes sense when leading technology is a sustained executive responsibility across product, people, operations and the board. A Fractional CTO can fit a defined transition, transformation or leadership gap, provided the agreed capacity and authority match the work. It is not a substitute for a full-time role that genuinely needs filling.

There are two different part-time answers. If you need someone to lead a transformation, a governance model or a team through a transition, that is a Fractional CTO: operational leadership with explicitly scoped authority and follow-through. If you need decision support without transferring operational ownership, that is advisory: CTO Advisor or CTO Advisor+.

Choose on the basis of ownership and organisational need, not only hours or price. Compare advisory and Fractional CTO engagements.

Two things happen on a repeating cycle: scheduled strategic sessions, and substantive advice between them.

On CTO Advisor that is typically two strategic sessions a month plus async advice in between. On CTO Advisor+ it is weekly or biweekly sessions, priority async, and a structured Quarterly Technology Review.

Sessions are working sessions, not status updates. You bring the decision that is blocking you, we work it through, and you leave with a position you can act on. Between sessions you send the things that come up: an architecture proposal to review, a hiring shortlist, a vendor quote that smells wrong, a roadmap you want stress-tested.

A Fractional CTO engagement runs differently: its cadence, presence and authority are scoped with you, because the role is to lead and follow through, not only to advise.

  • CTO Advisor, €1,500 per month excluding applicable taxes. Up to 4 hours a month of advisory capacity, typically two strategic sessions, async advice between them. For founders who own execution themselves and want senior judgement reviewing direction.
  • CTO Advisor+, €2,500 per month excluding applicable taxes. Up to 8 hours a month, weekly or biweekly sessions, priority async, and the Quarterly Technology Review. For companies where the technology decisions are arriving faster than one session a fortnight can absorb.
  • Fractional CTO, from €6,000 per month excluding applicable taxes. Embedded leadership with ownership where scoped: transformation programmes, governance, board and investor work, due diligence, and hands-on execution when explicitly agreed. Contact only, scoped individually, never self-service.
