What to expect from the dev agency after MVP is done?

Dear JK,

Your message landed in my inbox late Friday night, right as I was about to close the laptop and call it a day. I’ve been exactly where you are now—MVP shipped, adrenaline wearing off, a dozen browser tabs open on “what-now” checklists. So, while the coffee is still warm, let me walk you through the bits that matter (and a few that tend to bite if you ignore them).

First, the codebase itself. People treat “getting the repo URL” as the finish line, but the real work is turning that pile of commits into something a fresh developer can reason about in under a week. That’s where documentation—real, living docs—earns its keep. I’m talking API references, architecture diagrams, user stories, the whole shebang. Last year I spent a significant effort over a longer period producing a 100-page API description for a logistics platform (every endpoint, every edge case, even the goofy fallback we hacked in at 2 a.m.). Tedious, yes. But the new team was productive by Wednesday.

These days I lean on AI assistants to generate the first draft—GPT-based code explainers that crawl the repo and spit out decent summaries. It’s not magic; someone still needs to verify that “OrderServiceV2” is, in fact, the current one (spoiler: it never is). But it cuts the grunt work in half, and your in-house devs can query the bot instead of trawling Slack history. I could be wrong, but so far the combo of human review + AI scaffolding feels like the sweet spot.

Keep all that material somewhere neutral—Jira, Confluence, Notion, pick your poison—and export it regularly. The moment it lives only on the agency’s cloud, you’re negotiating from a weaker seat. (Side note: I lost two days once because a Confluence instance was tied to the agency’s SSO. Fun.)

On IP protection, the paperwork looks straightforward—contract, NDA, Statement of Work spelling out that you own every line once invoices are settled. Yet jurisdictional quirks and open-source licenses love to sneak through the gaps. I’ve seen a GPL dependency trigger a legal review that delayed an investment round. So, yes, “standard practice” exists, but bake in a sanity check by someone who actually reads licenses for sport.

The usual clause says ownership flips to you after final payment. If that timing worries you, stage payments against deliverables and hold a percentage until the handover finishes. Not every lawyer agrees this is elegant, but it keeps everyone motivated.

If tech isn’t your home turf, bring in a fractional CTO or senior advisor for the transition. One caveat: some veteran engineers bristle at the idea of being “prompt engineers” babysitting AI tools all day. Balance automation with old-school craftsmanship or you’ll alienate the folks you need most.

Now, the boring but vital logistics:

• Where is the code stored?
• Where is the code deployed?

Make sure you can yank access in minutes, not days. Separate production from staging keys, enable audit logs, and keep encrypted backups somewhere only you control. I learned this the messy way when a former partner still had SSH access and accidentally triggered a deployment script months later. No malice, just muscle memory—humans adapt at human speed.

About the handover itself: imagine a relay race where runners overlap for a few strides. Two hours of “knowledge transfer” won’t cut it unless your app is a to-do list clone. Plan for at least a month of overlap; three is safer. We once tried to compress it into two weeks and paid with a full day of downtime—database migrations mis-sequenced, monitoring alarms screaming, customers refreshing dashboards that never loaded. Not catastrophic, but embarrassing. There were ongoing issues that required further attention and taught us valuable lessons.

Ongoing support from the agency can be gold, provided you sandbox it. Time-boxed access, read-only logins where possible, and every session recorded. Set a clear SLA for ad-hoc help (“max 4 hours turnaround, billed hourly”) so you’re not funding an open-ended retainer.

I’m happy to jump in myself if you need an extra pair of eyes, but any seasoned tech lead with a bias for documentation will do. Just make sure someone owns the checklist; otherwise each task politely waits for someone else to pick it up.

Hope this gives you a clearer picture—and a few cautionary tales—of what to expect once the MVP bows out and the real marathon begins.

Cheers,
Vadim
