Real Impact, Real Results

Maintenance & support for teams who need their software to stay live

01

Always-on monitoring

We monitor servers, SSL certificates, and SDK compatibility so your application stays secure and current with the latest technologies.

02

Trained support team

Our engineers know your codebase. When something breaks, you are not starting from scratch with a vendor who has never seen your system.

03

Flexible ownership

Choose fully managed support, a hybrid co-development model, or structured hand-off to your internal team. You decide how much operational ownership to keep.

What we cover

What maintenance & support looks like in practice

Three pillars keep your application healthy after launch. Each one addresses a specific operational need that grows more pressing as your user base and feature set expand.

Maintenance

We handle environmental updates, language and framework upgrades, AWS server intervention and recovery, outdated library and SDK fixes, and security patches. Your application stays compatible with the latest technologies without your team needing to track every deprecation notice.

Support

Every live application needs an on-call detective. Our trained team responds to bug reports submitted via Slack or email, confirms tickets same business day, and resolves issues within 5 business days, prioritized by severity. Critical issues get 4 to 8 hour response times.

New features (M&S Plus)

Software is never complete. Our M&S Plus plan lets your team request additional features, UI/UX updates, performance optimization, and workflow refinements within your monthly support allocation. Available starting at the 80-hour tier for teams that want their application to keep improving, not just stay stable.

Engineering design

Your application, your infrastructure, your rules

Priority response levels

Critical issues get 4 to 8 hour response times. Significant problems resolve within 1 to 2 days. Minor issues within 3 to 5 days.

Covers web, mobile, and AI/ML

One support plan covers every environment we build. No separate vendors for your web app, mobile app, and AI system.

30-day notice to pause or cancel

No permanent lock-in. Give 30 days notice to pause or cancel your plan. We earn your retention every month.

our process

How we keep your software running

System audit

If we built your application, we already know the codebase. If not, we perform a technical due diligence review to understand your architecture, infrastructure, and dependencies before taking over support.

Maintenance & monitoring

We monitor servers, apply updates, fix outdated libraries, and keep your application compatible with evolving technologies. Security patches, SSL renewals, and SDK updates happen on a regular cadence.

Support & bug resolution

Your team submits issues via Slack or email. We confirm tickets same business day and resolve within 5 business days, prioritized by severity. Critical issues get 4 to 8 hour response times.

Feature development (M&S Plus)

For teams on the 80-hour plan or higher, support hours can be applied to new features, UI/UX updates, performance optimization, and workflow refinements. Your application keeps improving instead of just staying stable.

FAQs

Find your answer in seconds

Do you only maintain applications you built?

No. We service applications we build, and we also perform due diligence on existing systems to take over support. If your current vendor is unavailable or you want to bring maintenance in-house, we start with a technical audit to understand your architecture, infrastructure, and dependencies.

What does a typical maintenance plan include?

Environmental updates, language and framework upgrades, AWS server intervention and recovery, outdated library and SDK fixes, security patches, SSL certificate monitoring, and bug resolution. Bug reports are submitted via Slack or email, confirmed same business day, and resolved within 5 business days prioritized by severity.

How much does maintenance and support cost?

For low code and automation workflows, plans start at $2,500 per month. For custom AI and machine learning applications, plans start at $4,000 per month for 40 hours of support. Larger plans (80, 124, and 178 hours) unlock M&S Plus features, AI/ML engineering support, and structured hand-off training.

Can we use support hours for new features?

Yes, with the M&S Plus plan. Starting at the 80-hour tier, you can apply support hours toward new features, UI/UX updates, performance optimization, workflow refinements, and advanced AI/ML support. Standard M&S covers maintenance and bug resolution only.

What if we want to take over maintenance ourselves?

We offer a structured Client Team Hand-Off and Training path, available starting at the 124-hour tier. This includes hand-off documentation, training for your engineering or product management team, and optional product management support during the transition. You own the code, the infrastructure, and the data from day one.

Can we pause or cancel the plan?

Yes. Give 30 days notice to pause or cancel. No permanent lock-in. We earn your retention every month.
