Do you sign NDAs and work with overseas clients?

Yes. We sign NDAs before any detailed discussion and regularly partner with startups and enterprises in the US, UK, EU, and Middle East.

What engagement models do you offer?

Fixed-price projects, dedicated team (monthly retainer), or time-and-materials for evolving products. Most clients start with a paid discovery phase.

What SLA options do you offer?

We offer tiered plans - business hours (9×5), extended (16×5), and 24×7 for critical systems - with defined response times from 4 hours down to 30 minutes for P1 incidents.

Can maintenance include new features?

Yes. Most retainers allocate hours for bug fixes plus a monthly bucket for small features, UX tweaks, and dependency upgrades.

Overview

Why teams choose us for Maintenance

Trusted by startups and enterprises across 12+ countries

Software doesn't stop evolving at launch. Our support & maintenance practice keeps your product secure, performant, and aligned with business priorities - without the overhead of hiring a full in-house ops team.

You get a named squad, shared Slack or Teams channel, defined SLAs, and monthly health reports covering uptime, error rates, dependency status, and recommended improvements.

Whether you need break-fix coverage, 24/7 on-call, or a steady stream of enhancements, we scale the engagement to match your stage - from seed-stage apps to enterprise platforms serving millions of users.

Why Vextrosys

A partner built for serious products

Same team, no handoff

Engineers who built your product handle support - they know the architecture, not a generic helpdesk reading a script.

Proactive, not reactive

We monitor logs, errors, and performance trends and fix issues before users report them - often before you notice.

Transparent SLAs

Clear response times for P1-P4 issues, escalation paths, and monthly reports - no surprise invoices or vague scope.

Continuous improvement

Maintenance retainers include capacity for small enhancements, not just bugs - so your product keeps getting better.

Grow Curriculum

Grow - Education Platform

A global curriculum management platform serving 10,000+ church communities with lesson planning, media libraries, and multi-campus administration.

Challenge

Grow needed to replace fragmented spreadsheets and legacy tools with one scalable web platform that non-technical volunteers could use on Sunday mornings - without downtime during peak usage.

Solution

We rebuilt the core product on Next.js with role-based access, offline-friendly lesson views, and an admin console that cut weekly planning time dramatically. Auto-scaling on AWS handles traffic spikes during global launches.
