XentraSol — Where Innovation Meets Excellence
Engagement models

Four ways to work with us — priced and scoped openly

No discovery call required to understand how we engage. Here is the team shape, the cadence, the contract structure, and the typical investment for each model.

Discovery Sprint

Two to three weeks that turn an idea into a costed, de-risked plan.

Best for
Teams who need certainty on scope, architecture, and price before committing budget.
Team shape
Principal engineer, product strategist, designer — part-time
Cadence
Daily async updates, two working sessions per week, readout at the end
Contract
Fixed fee, standalone SOW, credited against the build if you proceed

Typical investment

$8K – $25K

Choose this when

  • The problem is clear but the solution shape is not
  • You need an internal business case with real numbers
  • Procurement wants a fixed scope before a larger SOW
Discuss this model

Project Delivery

Fixed scope, fixed price, one accountable team from kickoff to go-live.

Best for
Defined platforms, AI systems, and product builds with a known outcome and deadline.
Team shape
Delivery lead, 3–7 senior engineers, designer, QA
Cadence
Two-week sprints, Friday demos, live board and shared Slack
Contract
Fixed fee against a milestone schedule, warranty period included

Typical investment

$60K – $500K+

Choose this when

  • The outcome is defined and the deadline is real
  • You want a single vendor accountable for delivery
  • Internal engineering is at capacity
Discuss this model

Dedicated Engineering Team

A stable senior squad that learns your domain and ships continuously.

Best for
Ongoing product development where scope evolves faster than a fixed contract can.
Team shape
Named squad of 3–10, your roadmap, our delivery discipline
Cadence
Your rituals or ours — sprint planning, standups, retro, monthly roadmap review
Contract
Monthly retainer, 30-day notice, no lock-in

Typical investment

$18K – $90K / month

Choose this when

  • You have a roadmap, not a single project
  • Context retention matters more than raw headcount
  • You want to scale up and down without rehiring
Discuss this model

Staff Augmentation

Vetted senior engineers inside your team, under your process, from week one.

Best for
Internal teams that need specific senior capability quickly without a hiring cycle.
Team shape
1–6 engineers embedded in your squads, reporting to your leads
Cadence
Your standups, your board, your code review standards
Contract
Monthly per engineer, two-week trial period, exit any month

Typical investment

$6K – $14K / engineer / month

Choose this when

  • You know exactly what skills are missing
  • Hiring would take three to six months you don't have
  • You want to try before you commit
Discuss this model
What stays the same

Whatever the model, the delivery discipline doesn't change

Senior-only engineers, weekly working software, a named delivery lead, and full ownership of code and accounts on your side from day one.

Common questions

Choosing a model

If the outcome is defined, start with project delivery. If the roadmap is ongoing, start with a dedicated team. If you know exactly which skills are missing, start with augmentation. If any of that is still unclear, start with a discovery sprint — it costs the least and removes the most risk.

Not sure which model fits?
