AI that serves humanity
Talk to a specialistYou’ll be matched with the senior specialist—or small team—best suited to your context: a manager, engineer, architect, or a combination when useful. We shape the conversation to make it practical and valuable from the start.

— Engagement models

Choose the shape
of ownership.

The right model is less about headcount and more about who owns decisions, delivery, and risk.

A practical rule

If engineering is part of your roadmap, build a dedicated team. If demand is intermittent, start hourly. If the outcome is fully defined, use fixed scope.

01Recommended

Dedicated developers / teams

Stable capability around your roadmap.

One senior developer or a cross-functional team that stays with your product, learns the context, and compounds its impact over time.

Ownership
Vestov builds and supports the team. Delivery can be Vestov-led or integrated into your existing product organization.
Cadence
Dedicated monthly capacity with stable composition, direct communication, and a 3+ month horizon.
  • Core AI product development
  • Long-term engineering roadmap
  • Hard-to-hire specialist capability
  • Scaling an internal product team

Our preferred model when continuity, ownership, and deep product context matter.

02

Hourly / retainer

Senior capacity when priorities move.

For advisory, exploration, maintenance, or changing workloads that need strong engineering judgment without dedicated full-time capacity.

Ownership
Vestov owns the quality of the assigned work. Scope and priorities are managed jointly or by your internal lead.
Cadence
Usage-based billing or a reserved monthly retainer, with transparent time and written delivery updates.
  • Technical discovery
  • CTO-level advisory
  • Specialist implementation
  • Maintenance or scaling bursts

A flexible starting point with a clear path into a dedicated team when demand becomes continuous.

03

Fixed scope

A bounded problem. A defined outcome.

For a discovery phase, technical audit, proof of value, or clearly specified delivery milestone with stable requirements.

Ownership
Vestov owns the agreed scope, delivery, quality, and acceptance criteria.
Cadence
Milestone-based delivery with scope and acceptance criteria agreed before work begins.
  • Architecture or AI readiness audit
  • Focused MVP or integration
  • Defined modernization phase
  • Independent technical assessment

Used selectively. Not recommended when priorities or requirements are expected to change every week.

Responsibility,
made explicit.

No model is universally better. The strongest engagement is the one that matches your operating reality.

— Included in every model

Different structure.
Same standard.

  1. 01Senior technical oversight

    Architecture and delivery decisions stay visible to experienced engineers.

  2. 02Clear communication

    Written status, risks, decisions, and next steps—without a black box.

  3. 03Security by design

    Access control, privacy, and production readiness are built into the work.

  4. 04Continuity

    We manage hiring, performance, knowledge transfer, and replacement risk.
