Engagement Models

Four structured ways we work together.

Direct Answer

Vanthrope engineers custom operational software and autonomous agent systems for mid-market enterprises. We engage through fixed-price discovery sprints, milestone-backed builds, embedded forward-deployed engineering, and ongoing care plans. All pricing is transparent and scoped after discovery, with contract-backed acceptance tests agreed up front.

Contract-Backed Guarantee

Contract-backed acceptance tests agreed up front before deployment. You do not pay final milestone balances until all agreed test criteria pass on staging environments.

1–2 WeeksFixed price

Discovery Sprint

Process map, risks, architectural options, and throwaway prototype before any build commitment.

Included Deliverables:

Complete current-state process map with identified bottlenecks

Failure-mode and security risk assessment

Architecture specification with two implementation options

Clickable prototype or staging test proving core technical feasibility

Ideal For: Businesses that know they have operational friction but need rigorous technical analysis before committing capital.

4–8 WeeksScoped after discovery

Fixed-Scope Build

Milestone-driven production deployment with acceptance tests agreed up front in writing.

Included Deliverables:

Deterministic database and agent middleware deployment

Custom web interfaces for clerk input and supervisor review

100% test coverage over critical financial and inventory paths

Staff training sessions, runbooks, and cloud repository handover

Ideal For: Operations with clearly defined workflows that need a production-grade system delivered without cost overruns.

1–3 MonthsScoped after discovery

Embedded Build

Forward-deployed engineering alongside your operational team for complex, evolving workflows.

Included Deliverables:

Direct pairing with department heads and software teams

Continuous weekly feature rollouts and immediate line adaptations

System architecture scaling and database optimization

Internal technical leadership and junior engineer mentoring

Ideal For: High-growth mid-market firms undergoing rapid restructuring or multi-system ERP overhauls.

Monthly RetainerScoped after discovery

Care Plan

Continuous monitoring, verified backups, access reviews, prompt hardening, and small feature updates.

Included Deliverables:

24/7 uptime and anomaly alert monitoring

Monthly backup restoration verification tests

Quarterly security access and third-party API token audits

Dedicated allocation of developer hours for small operational tweaks

Ideal For: Clients running mission-critical systems that require guaranteed maintenance and zero staff worry.
