Retainer · From $2,000/mo · 3-month minimum

A senior engineer who watches your AI-built app so you don't have to.

After the audit and the hardening, the work isn't done — it's started. Dependencies drift. SaaS providers change APIs. The AI you used last month suggests a new pattern that breaks the old one. Maintenance is the boring, expensive part. We do it monthly, on a flat retainer.

Talk about retainer Start with an audit

Who this is for

Founders who shipped — and now need to keep it shipped.

Maintenance is the right fit when the app is live, has users, and there is no internal engineer to mind it.

Solo founder, live app

You shipped, customers showed up, and now you're scared to touch it

Every change might break something. We become the team that touches it for you.

Post-audit team

You ran the audit, knocked out the criticals, now what?

The medium-risk findings, the slow drift, the new features. We pick those up on a steady cadence.

Bridge to first hire

You're hiring an engineer in 6 months

Until then, we keep the lights on, document everything, and hand off cleanly when your hire starts.

What we do

Boring, on-time, and ours.

A monthly cadence that keeps small problems from becoming launch-week emergencies.

  • Monitoring & alerts. Sentry, Better Uptime, log-based alerts. We get paged, not you.
  • Dependency updates. Patch + minor monthly, major upgrades planned. CVE response within 24h.
  • Backup verification. We restore your DB to a sandbox monthly. Untested backups are not backups.
  • Small features & fixes. Roughly 8–12h/month of build, with a clear queue you control.
  • Incident response. When something breaks, we respond, fix, and write a 1-page post-mortem.
  • Cost watch. LLM bills, hosting, SaaS. If a line item doubles, you'll hear about it that week.
  • Monthly status note. What we did. What's next. Where the risks moved.
  • Vendor & tool advice. Should we move off Replit? Switch from Vercel? We answer with reasons, not vibes.

Red flags

Signs you needed maintenance yesterday.

If two of these are true, the next bad day will be expensive.

M-01Critical

You haven't deployed in 60+ days

Your dependencies have CVEs. Your AI tool has changed defaults. You're frozen because nobody knows what will break.

M-02Critical

You don't know if backups work

You've never tested a restore. The day you need them, you'll learn whether they exist.

M-03High

Customer issues come in via DMs

No error tracking, no support inbox, no ticket trail. Bugs hit the floor and stay there.

M-04High

Your dev quit and left no docs

The previous contractor is gone. The README has a typo from 2023. We can take inventory.

M-05High

Your hosting bill is creeping up

Auto-scaling that nobody capped. An LLM endpoint somewhere getting hit too often. We find it.

M-06Worth checking

You're afraid to touch the code

That fear is the problem. Maintenance is what gives you permission to ship again.

Tiers

Pricing that matches the size of the app.

Pick by app surface, not by team size. We'll suggest one in the intake call.

Tier 1·Watchful

$2,000/mo

Best for: post-audit teams with a stable app and limited change rate.

  • Monitoring & monthly checks
  • Dependency updates
  • Up to 4h/mo of small fixes
  • Business-hours response

Tier 3·On-call

$8,000/mo

Best for: revenue-critical apps, regulated workloads, on-call required.

  • Everything in Active
  • 24/7 on-call, 30-min Critical
  • 20–28h/mo of build
  • Quarterly mini-audit

FAQ

Maintenance retainer questions.

01 What's the minimum commitment?
Three months. Cancellable thereafter with 30 days' notice. We don't lock anyone in — but the first month is mostly setup, so a one-month engagement isn't fair to either of us.
02 Do you respond to incidents at 3am?
On Tier 3 (on-call), yes — within 30 minutes for confirmed Critical. On Tiers 1 and 2, business-hours only. Both are stated in the SOW.
03 Can you build new features?
Small ones, yes. We allocate roughly 30% of the retainer to small improvements. Larger features get scoped as a separate sprint.
04 Do I need to do an audit first?
Strongly recommended. The first month of maintenance is much more useful when we already know where the bodies are buried. We discount the audit fee from the first month if you do both.
05 What if you can't fix something?
We tell you, and we help you find the right specialist. Senior judgment includes knowing what we are not the best person for.
06 How is this different from CTO-Lite?
Maintenance is mostly hands-on-keyboard. CTO-Lite is mostly judgment, hiring, vendor calls, board prep. Many founders take both — different people, different cadence.
