Your agent can build anything, fast.
It can’t tell you what’s next.
It knows your code. It doesn’t know your users’ needs, your data, or what matters next. That’s a product manager’s job.

Meet Nano.
The PM agent that decides what’s next.
Nano is your product partner, continuously figuring out what matters most and directing your coding agent toward the highest-impact work.

The AI PM your
projects deserve
Projects don’t die of bad code. They die of guessing.
Nano watches your product so you don’t have to, and tells you what matters.
Your product keeps moving while you’re busy elsewhere.
NanoReading this week’s support emails
14 shoppers left at checkout this week. They want the delivery date before they pay. Proposing: show it on the product page.
Nano listens to your users
Nano checks user feedback and what your users actually do, not what you hope they do. Every decision starts there.
Nano reads your data
Stripe, PostHog, Supabase, GitHub, your support inbox. 500+ more through MCP. Queried at the source, nothing to instrument.
NanoQuerying PostHog
Retention held at 46% after the onboarding fix. Up from 41%. Keeping it.
NanoReading competitor changelogs
A competitor shipped team seats. Your users are solo. Not a priority.
Nano scans your market
Competitors, feedback, what people are asking for elsewhere. Nano does the research a good PM does before deciding.
Nano proposes. You decide.
One proposal at a time, explained, on the record. You approve, Nano hands it to Claude Code or Codex. When you trust it, switch to autopilot.
NanoWeighing the two options
Pricing page before dark mode. 14 users asked for it, none for dark mode.
Nano doesn’t work alone.
It leads a crew.
For the work that matters most, Nano calls in specialist agents. They all share your business context, each does one job well, and they check each other’s work.
Your business context
Market
Scans competitors and what people ask for elsewhere.
User feedback
Reads every review, ticket and message your users send.
Data
Queries your numbers at the source and checks the math.
Opportunities
Sorts every signal into the problems worth solving.
Solutions
Brainstorms options, then argues them down to one.
Roadmap
Keeps the plan in order after every deploy.
A whole product team.
For builders who can’t hire one.
NanoPM is a product management harness: Nano, six specialist crews and your business context, wired around the coding agent you already use.
A PM you can
argue with.
Nano is one click away on every screen of the app. Pitch it an idea, ask it to work on a feature, push back on its plan. It always answers with a PM’s mindset: your users, your numbers and your goal first. Then it does the work.

Video walkthrough on every listing
BigHEA-S1Trust before the visit
🎯 Problem we are solving
1 I can’t trust a flat I can’t visit
✨ In short
Every listing shows the flat on video before it goes live, so a renter in another city can trust what they apply for.
💡 Proposed solution
The landlord uploads a two-minute walkthrough with the listing, edited, with a voice-over of each room.
The landlord films one take in the app, on their phone, room by room. Hearth trims it and puts it first on the listing. No editing on their side.
📏 How we’ll know
Out-of-town applications up by a fifth within four weeks.
Half of new listings carry a video within two weeks.
🚫 What we won’t do
Live video visits. That’s the next card.
Your business,
always in context.
A coding agent starts every session knowing nothing about your business. Nano doesn’t. At onboarding it infers your business card from your code and docs (what you sell, the people you build for, the market you’re in), you confirm it line by line, and it keeps it true. Like any good PM, it can’t do great work without it.

Most projects build whatever was asked for last. Nano ranks every idea by what moves your one goal, and says no to the rest. Small, clear fixes skip the queue in the fast lane, so the big bets never wait on a typo.

Specs for you,
and for your agent.
A vague prompt gets a vague feature. Nano writes each bet first as a doc you read in two minutes: the problem, the experience, what not to build. It sets up the analytics, keeps them working and draws the goal on a chart, so you know if it worked. When it’s time to build, it turns the doc into a spec for your agent.

BigTrust before the visit
🎯 Problem we are solving
1 I can’t trust a flat I can’t visit
✨ In short
Every listing shows the flat on video before it goes live, so a renter in another city can trust what they apply for.
🧭 The experience
- The landlord opens their listing and taps “Film the flat”.
- The app guides one take, room by room, on their phone.
- Hearth trims it, checks it, and puts it first on the listing.
- A renter in Lyon sees the flat before a single photo.
📣 Future changelog
See every flat before you apply.
- A video walkthrough on every listing.
- Filmed by the landlord, checked by Hearth.
📏 How we’ll know
Out-of-town applications per week, up by a fifth within four weeks of launch.

# Video walkthrough on every listing
> Spec for a coding agent, written by NanoPM on 2026-10-07
> from the solution HEA-S1. Code read at a3f9c1.
## Goal
Landlords film one take in the app; Hearth trims it and
shows it first on the listing.
## Plan
1. Listing gets a `walkthrough` (url, seconds, status).
2. apps/mobile/listing/film.tsx: one take, room prompts.
3. jobs/trim-walkthrough.ts: trim, check, publish.
4. The video leads the gallery, on web and on mobile.
## Analytics
- Walkthrough Filmed { listing_id, seconds }
- Walkthrough Viewed { listing_id, renter_city }
## Done when
- A filmed listing shows its video first, on every client.
- Both events reach PostHog with their properties.From spec
to shipped.
The handover follows the best practices for coding agents: a spec written for the agent, a copy of your repo, a plan in small steps, checks run before anything reaches you. Claude Code builds, you review one pull request, and Nano watches whether it worked.
