ThumbsumCanny vs Thumbsum: a board that collects vs a PM that decides
Short version: Canny is an excellent place for feedback to live. Thumbsum is what happens to feedback after it arrives. They overlap on every visible organ and differ completely on the invisible one — who does the triage.
We build Thumbsum, so read this knowing that. We have kept the comparison structural — assumptions and mechanics, not adjectives — so a Canny fan could check every claim against their own board.
Where they are the same
Both give you a public feedback board with voting, duplicate handling, a public roadmap, a changelog, and the credibility of visibly listening. If your evaluation stops at "do my customers have a good place to post and can they see we care" — a legitimate place to stop — both tools pass, and Canny is the longer-established choice with the wider integration catalog.
Migration between them is also unglamorous in a good way: Thumbsum imports Canny CSV exports, posts and voters included, with authors matched to their revenue data on arrival. (The walkthrough takes about fifteen minutes.)
Difference 1: what happens to a new post
Canny: the post waits. Someone on your team reads it, merges it with duplicates they remember or search for, tags it, and weighs it in the next planning pass. Canny gives that person genuinely good tools — the merge flow is one of the best in the category.
Thumbsum: the post is read on arrival by the system itself. The concrete ask is extracted in ten words or fewer ("per-event notification settings or daily digest" — not just "notifications feedback"), the type and sentiment are noted, personal information is caught before anything goes public, and the post is grouped with every other post that means the same thing regardless of wording. "Search ignores hyphens" and "wi-fi returns nothing but wifi works" land in the same group with no human touching either.
The distinction that matters: in Canny, an unread post is untriaged. In Thumbsum, unread and triaged are independent — the system has already done its part before you log in.
Difference 2: how priority is decided
Canny: votes, plus whatever prioritization your team layers on top (Canny offers scoring frameworks for this). Votes measure enthusiasm, and enthusiasm skews toward users with time to campaign — which skews away from your largest, busiest accounts.
Thumbsum: arithmetic on your revenue data. Every group carries the monthly revenue behind it (summed per person, never per post — one customer filing three duplicates is one customer), the largest single account asking, the count of distinct paying accounts, and how long the oldest voice has waited. The queue holds five cards ranked by that math, and each card shows its work: "3 requests from $428/mo of accounts, 2 paying, unanswered 3 days."
We call this receipts, and it is the philosophical center of the product: the words are written by AI, but the decisions are arithmetic you can audit. Ask "why is this first?" and the answer is already printed on the card. Same data in, same queue out, every time.
Difference 3: the unhappy customer
Canny: an angry post from your biggest account renders identically to every other post until a human notices it. Detection depends on the reader's attention on the right day.
Thumbsum: a paying customer with a negative report and no reply is a distinct, automatic alarm — a card naming the person, their monthly revenue, and their wait time, carrying a drafted personal reply. If five paying customers are unhappy in the same group, the card lists all five with individual drafts, and it does not consider itself handled until every paying voice has been answered. Churn risk is treated as what it is: a countdown, not a post.
Difference 4: after you ship
Canny: you update the status, subscribers get a notification, and you write the changelog entry.
Thumbsum: shipping triggers three things. Everyone who asked gets a drafted personal email — sent individually with one click, each greeting the requester by name and referencing their ask. The changelog entry drafts itself from what was actually requested and credits "the 6 people who asked." And the request group retires from your queue on its own, because the facts now say it is done. The philosophy is that "shipped but nobody told" is unfinished work, and the system should remember the names so you do not have to. (Why this matters more than it sounds: closing the loop, properly.)
Difference 5: pricing shape
Canny's pricing scales with team size and usage — coherent for team software. Thumbsum is flat per workspace: $49, $79, or $149 a month depending on volume and channels, every tier including the full judgment engine. The reasoning is one sentence: a PM has a salary, not seats. Your data exports completely, in one click, on any plan — worth checking on any tool you evaluate, ours included.
Who should pick which
Pick Canny if a human on your team genuinely does triage — a PM, or a founder whose calendar actually protects the reading time. You will get the category's most mature board and the widest integrations, and the manual control is a feature when someone is there to exercise it.
Pick Thumbsum if that human does not exist — if you are the founder-PM-support-engineer and the honest answer to "who reads the board" is "eventually, me." The board parity means your customers lose nothing; the difference is that the reading, grouping, weighing, and remembering happen whether or not you had a good week.
And if you are unsure which you are: run the manual system for one month in a spreadsheet. If you keep it up, you are a Canny person. If it collapses in week two, you have your answer — and either conclusion is worth more than any comparison page, including this one.
