You shipped your MVP. Now what?
Tero is the engineer + PM that watches your analytics and ships small improvements while you sleep — with your approval, never without it.

It's 2am. You shipped your MVP last week. Sign-ups are coming in. Conversion is 3%.
You open the codebase your AI tool generated. You squint at it. You change one thing on the onboarding screen, deploy, and now the login page is broken. You revert. You wait. You go to bed angry.
The next day you tell yourself you'll figure it out this weekend. The weekend comes. You spend Saturday in Cursor trying to get a button to align right. Sunday you're back where you started, conversion is still 3%, and you've added two new bugs you don't know about yet.
If this is you, this post is for you.
The real problem isn't shipping features
You don't have a "I can't ship features" problem. Your AI tool already shipped you a working product. That part worked.
You have a different problem: you can't reliably improve the product without breaking it.
There's a gap between "ship MVP" and "make it actually work for users" that nobody warned you about. The MVP is a demo. The thing that converts at 25% instead of 3% is a hundred small fixes — copy that's clearer, a button placed differently, an empty state that doesn't make a first-time user feel lost, a form that doesn't reject their email because it has a + in it. Those fixes are individually small. Collectively they're the difference between a product that works and a screenshot that doesn't.
The problem is that each of those fixes requires you to:
1. Notice it's a problem (you're not watching every session) 2. Figure out which fix to try 3. Change the code without breaking three other things 4. Confirm it actually helped instead of just feeling like it did
If you built on Lovable, Bolt, Replit, v0, or Cursor and your codebase has now grown beyond what you can safely change in your head, you know exactly what I mean. The code your AI tool wrote works, but every change is a coin flip on whether something else breaks.
What Tero does
Tero is the senior engineer and product manager you can't afford to hire yet. It works while you sleep, it watches your analytics, and it ships small improvements one PR at a time — with your approval, never without it.
Here's the actual flow:
1. Connect your GitHub repo. Two clicks. Tero installs as a GitHub App so it can open PRs as tero-agent[bot] instead of as you. 2. Tero reads your codebase. It figures out what your product does, what the main screens are, where users sign up and where they activate. 3. Tero adds analytics. If your project doesn't already have PostHog, Mixpanel, or Amplitude wired up, Tero will instrument the right events — signup, activation, key flows. (You connect the analytics provider; Tero writes the tracking code.) 4. Tero watches. Every six hours, it scans your funnel. If a step starts losing more users than usual, it kicks off a Multiverse run. 5. Tero ships. When it finds something worth fixing, it generates the fix, pre-tests it against five simulated users, runs a real-traffic A/B test, and — if the variant actually beats your current version — sends you an iMessage with the PR. 6. You reply "ship it." Tero merges. The change goes live.
That last part isn't a metaphor. You literally reply "ship it" (or "yes," or 👍) over iMessage, and Tero merges the PR. No dashboard, no Slack thread, no meeting.
The Multiverse loop, with a real example
Let's walk through one concrete scenario.
You shipped your app two weeks ago. PostHog (which Tero set up for you) shows your funnel:
- 1,000 visitors land on the homepage - 400 click "Get started" - 250 finish the signup form - 40 reach the dashboard
That last step is bleeding. 250 people created an account, 210 of them never made it to the dashboard. You don't know why.
Here's what happens next, from your point of view:
Day 1, 6:00am. You wake up to an iMessage:
> "Heads-up — your activation step (signup → dashboard) dropped 32% this week. I'm trying four different fixes. I'll let you know when one beats your current version on real users."
You don't have to do anything. You drink your coffee.
Day 1, behind the scenes. Tero figures out which page owns the signup → dashboard step. It generates four variants of that …
