Choosing a Slack alternative for a small company: seven questions
Small companies usually start looking for a Slack alternative for one of two reasons: the bill, or the feeling that conversation has become the whole job. The first is easy to compare. The second is not, and it is the one that actually costs you something.
Feature lists do not help much here, because the products in this category all have the same features. What separates them is where the work lives once the conversation ends. These are seven questions to ask, in the order they matter for a company of about ten people.
Everything said about Slack below comes from what Slack is: team messaging with channels, direct messages and a large ecosystem of integrations around it. That is a good product described accurately. The question is whether it describes the thing your company should run on.
Does it follow up, or only notify?
A notification tells you something happened. Following up means somebody notices when the thing that was supposed to happen did not.
Every messaging tool notifies. Slack has reminders inside chat, and they work the way reminders work: you have to set one, and you have to be the person who remembered to set it. The unattended case is the one that matters. Nobody set a reminder, and three days later the request is still unanswered.
At a thousand people that gap is somebody’s job. At ten it is nobody’s job, which means it has to be a property of the system or it does not exist. Ask any candidate product what happens to a promise that nobody wrote down.
Where do todos live?
This is the question that tells you the most, and it has only two possible answers.
Either todos are part of the product, or the product connects to the place your todos already are. Slack is the second kind: it has reminders inside chat, and many teams keep their actual tasks in another tool. That is a reasonable design for a messaging product.
The cost shows up in one specific moment. A decision gets made in a thread, and turning it into a todo is a separate act, in a separate tool, done by a person who has to remember. Most of the time they do. The rest of the time the decision exists only in the thread, and the thread scrolls.
Are deadlines visible without a meeting?
Ask how a person who is not in a thread finds out that a date moved.
If the honest answer is “somebody mentions it at the standup”, the deadline lives in a meeting, and the meeting is the only place the company is synchronised. That is expensive at any size, and at ten people it is usually the meeting everyone quietly resents.
A date should be attached to the thing it applies to and visible to the people who plan around it without anybody announcing it. Whether the tool you are looking at can do that is worth five minutes of testing before you move.
Who can read what?
In a small company this question feels rude to ask and is worth asking anyway, because the answer becomes permanent the day you migrate.
Two parts to it. First, what can an administrator see? In Slack this depends on your plan and your export settings. Second, what can the AI features see? Slack’s AI features depend on your plan too, and what they know about you is your message history, searchable.
Neither of those is a scandal. They are the normal arrangement for a workspace-level product: the workspace is the unit, so the workspace is what the boundaries are drawn around. The question for a founder is whether you want that unit to be the workspace or the person, because it determines what people will and will not say in the tool. Where private is genuinely private, the hard conversations happen in the tool. Where it depends, they move somewhere you cannot see at all.
Does it draft for you, and can it ever send as you?
These are two questions and people usually ask only the first.
Drafting is the useful part: something that reads the thread and writes the reply you were going to write saves real minutes, several times a day.
Sending is the part that deserves a firm answer. In Slack you send; apps can post as you if you allow it. “If you allow it” is the load-bearing phrase, because permission granted once tends to stay granted, and nobody re-reads it at the moment it matters.
The answer to look for is a rule rather than a setting: it drafts, you send, and there is no arrangement in which something goes out under your name because you clicked something last March. Ask whether anything it writes is marked as written by it, so the people reading know which sentences came from a person.
What happens to what it learns about you?
Anything that reads your work accumulates a picture of you. The useful question is not whether it has a memory. It is who controls that memory.
Three follow-ups, all answerable in a demo. Does it tell you what it decided to remember? Can you see the whole list? Can you delete an entry and have it actually be gone?
If the answer to the first one is no, the other two do not matter much, because you cannot correct something you were never shown. A memory you confirm is a different product from a searchable history of everything you ever typed, even when both are described with the same word.
Can one person start before the company decides?
A small company cannot afford a migration. Ten people changing tools in the same week means a week where nobody can find anything, followed by a quiet return to the old tool. Any evaluation that requires a company-wide decision on day one will not survive contact with a busy month.
So ask whether one person can run their own week on it while everybody else carries on as before. If they can, you get a real trial at the price of one person’s habits. If they cannot, you are being asked to bet the company’s attention on a demo.
What the seven questions add up to
Read the answers together and you usually find they are not seven separate answers. They are one answer, asked seven ways: is this a place where a team talks, or a place where a company runs?
Slack is very good at the first. If you depend on channels, or on an integration that only exists there, or you want a messaging tool and nothing else, it remains the better choice, and the honest advice is to stay. The seven questions are for the founders whose real problem is the second thing.
Where Opitor fits
Opitor is an AI-native operating system for small companies, where every person gets their own AI chief of staff. Messages are direct and group rather than channels, the Todo List and its deadlines are part of the same product, and the company’s quarterly goals (OKR) are managed by administrators. Each person’s chief of staff follows up their todos and deadlines and drafts for them, and it never sends: everything it writes is signed in purple, memory is proposed after a conversation and used only once you confirm it, you can see and delete all of it, and administrators have no override. Opitor is free to start, there are no paid plans yet, and one person can start alone and invite the team later. The side-by-side version is on Opitor vs Slack, and the questions and answers page covers what is included.
