01The operating model
Three disciplines. One delivery loop.
We call this unit a triada: senior fullstack, QA, and DevOps specialists working as one coordinated product team — one Slack channel, one invoice, and one partner accountable for the outcome. It is built for startups and growth-stage teams that need senior delivery without three separate hiring processes.
Quality Assurance
Automated suites and manual exploratory testing protect every feature before it reaches your users.
output: verified release
DevOps & Infrastructure
CI/CD, cloud infrastructure, monitoring, cost control, and incident response keep the product dependable after launch.

04Why Crewgent
Senior delivery. Lower cost. Your hours.
We are based in Colombia and work with clients worldwide. Overlap is scheduled to your working hours — not a fixed market timezone. Because of where we hire, our quotes sit below typical local agency rates for the same seniority.
No lock-in. Cancel anytime. The repository, cloud accounts, and documentation belong to you from day one.

AI_AUGMENTED
We use AI tooling openly: senior engineers use it to move faster while remaining responsible for architecture, quality, security, and every production decision.
06Common questions
Clear terms before we start.
Senior engineers from our vetted Colombian talent pool, coordinated and quality-controlled by Crewgent's founding partners. You contract role coverage, and we take responsibility as one delivery team.
Because every product has different architecture, risk, and delivery needs. We scope yours in a free audit and quote only the team and work it requires.
You do. Repositories live in your accounts, infrastructure runs in your cloud, and IP transfers on payment. If we part ways, the product keeps working and the assets remain yours.
Yes. Retainers are prepaid monthly and can be canceled without a minimum term. We hand over cleanly with current documentation.
We invoice in USD. Build projects are billed 50% upfront and 50% on delivery, or by milestones for larger scopes. Run is prepaid monthly, and Rescue is billed only for approved active work.
