Corroso reads your Zendesk tickets, Canny votes, Linear issues, and codebase. It answers the two questions that matter: is there real demand, and how long will it actually take? Every number cites its source. Then it pushes the tickets.
Team collaboration appears in 28% of support tickets1 and is the #2 most-requested feature2. Two enterprise accounts representing $48k ARR3 named it a renewal blocker. Build cost is low: your codebase already has a real-time presence layer4, so this is ~3 weeks, not ~10.
Every planning cycle without cited evidence is a week shipping the wrong thing with a story you can't defend.
Right now your demand signal is scattered: support tickets in Zendesk, feature votes on Canny, sales call notes in a Notion doc nobody reads, and NPS responses in a spreadsheet from last quarter. Every planning cycle, someone spends two weeks manually tagging 4,000 items and pasting summaries into slides.
Don't write a brief. Just describe what you're considering, the way you'd explain it to your eng lead over coffee. Corroso retrieves everything relevant from your connected sources: every matching ticket, vote, sales note, and code file, with provenance kept on each piece.
ChatGPT gives you a framework. Corroso gives you: 23 tickets, 9 accounts, $284k ARR, 2 open deals. The relevant files are already in src/reports/export.ts, so this is 2 weeks not 8.
The output is a full PRD structured around Must / Should / Avoid. Every requirement traces back to a cited source: the ticket, the vote count, the sales note. A stakeholder who challenges the priority can be shown the exact evidence. The loudest voice in the planning meeting doesn't win anymore.
The PRD goes to your team before anything enters the backlog. Assign required reviewers (eng lead, designer, CEO) whose approval gates the next step. Optional reviewers (CS, sales) can add context without blocking. Pin it to a roadmap quarter.
Once the PRD is approved, Corroso drafts the Jira or Linear tickets. Each ticket carries the demand signal that justifies it, the codebase context that scopes it, and a testable acceptance criteria checklist. Engineers don't need a sync to understand why this matters or how to approach it.
src/api/rate-limiter.ts.export_status enumEvery build decision is two questions: is there demand, and is it feasible. The wrong project costs more than money; it burns engineering investigation time too. Corroso runs that investigation before the POC: demand from your tickets and feature requests, feasibility from your codebase (what already exists, what's reusable, the real approach). A raw chatbot can't hold both and cite them. That's the difference.
If Corroso can't link a quantitative claim to an ingested source, it says "no internal evidence found." It never invents a number to fill the gap.
You'll never see "expected revenue: $145,000." If a number can't cite a source, you get an honest abstain, never an invented figure.

The output is a draft you own and edit. We measure the share of PRDs shipped with minimal edits as our own quality signal, not the other way around.
Zeda.io is shutting down. Cycle.app was acquired and sunset. ProductBoard Spark is still in beta. The seed/Series-A PM has been left with enterprise tools priced at $70K/year or IC writing assistants with no evidence. Corroso is the missing middle: cited decisions, not just generated documents. At a team price a Head of Product can approve this afternoon.

Import your CSV export in < 5 minutes. Your feature backlog becomes cited evidence in Corroso. Nothing lost.
Migrate free →Corroso is the evidence layer for deciding what to build (and fix) next. It connects to your tickets, feature requests, and codebase and crosses them to answer two questions before you commit: is there demand, and how exactly would we build it? Feasibility isn't just an effort number. It's the engineering investigation done from your code, before you build. Every claim cites its source. Then it drafts the Jira/Linear tickets.
A chatbot can't hold your live tickets and your private codebase on one connection and cite both. Corroso stays wired to your data, gives you verifiable clickable citations instead of a one-off paste-in, and drafts the tickets that put the decision in motion.
Technical founders, Heads of Product, VPs of Product, and engineering/platform leads at seed and Series-A startups who own build decisions and have no product-ops team or analyst to delegate to.
No. If Corroso can't link a claim to a real source, it says "no internal evidence found" instead of inventing a figure. It avoids false precision and excludes revenue simulation on purpose: a projection can't cite a source.
Seed or Series-A, a small product team, no analyst to delegate to. If decisions ride on you and you're tired of defending guesses, request access and we'll reach out personally.
