Clari and Aviso both promise to tell you what your quarter will close at. The real split is over who does the work - your reps clicking through a CRM, or software that acts on its own.
Every revenue tool now says the same three letters. "AI forecasting" is on every homepage, in every deck, next to every accuracy stat. Which makes it a bad way to tell two products apart. The more useful question is quieter and slightly uncomfortable: when the software notices a deal slipping, what does it do next? Does it tell a human, or does it just handle it? Clari and Aviso answer that differently, and the answer is the whole strategy.
On paper they sit in the same box - revenue intelligence, pipeline inspection, forecasting for B2B go-to-market teams. Both were founded in the early 2010s. Both will happily quote you a forecast-accuracy number that starts with a nine. But they are betting on opposite ideas about how much of a sales team's work should be done by people, and how much should be done by software running on its own.
Clari was co-founded in 2013 by Andy Byrne and Venkat Rangan in Sunnyvale. Its original insight was almost boring, which is usually a sign it was right: sales forecasts were guesses dressed up as numbers, and the fix was rigor. Inspect the pipeline. Trust the roll-up. Give a VP of Sales a forecast they could defend to a board without sweating.
It worked. Clari is now the category's heavyweight - roughly $2.6 billion in valuation, more than $510 million raised, and by its own account something like $5 trillion in revenue managed for 1,500-plus customers including Adobe, IBM, 3M and Zoom. When forecasting turned into a commodity, Clari did what incumbents do: it bought its way into a bigger surface area. Wingman for conversation intelligence in 2022. Groove for sales engagement in 2023. Then, in December 2025, a merger with Salesloft that it markets as the first "Predictive Revenue System."
The through-line in all of that is trust. Clari's pitch has always been that a forecast is only useful if people believe it, and belief comes from disciplined process - clean roll-ups, native Salesforce integration, mature inspection. It is a serious tool for large organizations that would rather have a number they can stand behind than a robot that surprises them.
The forecast used to be the product. Now it's the floor. What sits on top of it is the actual fight.The read on where sales software is going
Aviso is, in a small twist most people miss, older than Clari - founded in 2012 by Andrew Abrahams and KV Rao in Redwood City. For years it was the quieter, more forecasting-obsessed alternative, leaning on predictive deep-learning models where Clari leaned on snapshots and roll-ups. It is much smaller: an estimated $37 million in ARR in 2025, up sharply from $12.8 million the year before, on only about $46 million raised. Scrappy, by the standards of a $2.6 billion rival.
But in 2025 Aviso stopped competing on accuracy and started competing on autonomy. It shipped a No-Code Agent Studio with more than 50 task-based agents, an orchestrator it calls MIKI, and a set of role-specific "AI Avatars" - an inbound SDR, a sales engineer, a coach, a customer-success agent - framed as autonomous extensions of the GTM team. The pitch is that these agents do not just surface a recommendation; they execute the task.
Aviso's marketing spine is a single, slightly rude line: Clari reports the news, we change it. Whether that framing is fair is genuinely debatable - Clari does far more than report, and Aviso's autonomy claims deserve the same skepticism any vendor's do. But the jab did something useful for the whole category. It moved the argument off accuracy, where everyone's numbers look suspiciously similar, and onto philosophy, where the two companies actually disagree.
Strip away the logos and the fault line is simple. When the model flags a deal as at-risk, one philosophy hands that insight to a human who decides what to do. The other lets an agent take the next step - draft the follow-up, update the record, nudge the rep, schedule the thing - and reports back. Clari's center of gravity is the first. Aviso is sprinting toward the second.
There is a small decision buried in each company's history that maps to the whole thing. When Clari wanted conversation intelligence, it acquired Wingman. When Aviso wanted it, it built the feature natively so the transcript could feed its deal scores directly. Buy the capability versus build it into the loop - that is a philosophy expressed as a purchase order.
Illustrative positioning based on each company's public product framing, not a benchmark. Numbers on a homepage are marketing until a procurement team stress-tests them.
Neither bet is obviously correct, which is exactly why the comparison is worth your time. Autonomy is only valuable to the degree you trust the software to act without you. A large, regulated enterprise with a complicated pipeline may want Clari's defensible roll-ups precisely because it does not want surprises. A faster-moving team drowning in repetitive CRM work may want Aviso's agents to just handle it, and may be happy to pay less per rep for the privilege.
Clari vs Aviso is really a bet on how much you trust software to act without you.The question underneath the feature lists
If you are evaluating either one, skip the accuracy-percentage arms race - both will show you a good number, and both numbers are marketing until your own data proves otherwise. Ask the operational questions instead. How long is implementation, and what does it cost you in weeks of ramp? How much of your team's time is spent on tasks a well-scoped agent could take over? And, most honestly: how comfortable is your organization with software that acts on its own, versus software that waits to be told?
That last question is the whole thing. The forecast is a commodity. The interesting product decision - the one Clari and Aviso answer in opposite directions - is what the software does the moment after it knows the answer.
Clari centers on disciplined pipeline inspection, roll-up rigor and platform breadth. Aviso leans harder into autonomous, agent-driven forecasting - software that executes tasks across the GTM process rather than only surfacing them.
Clari. It reached a $2.6B valuation, manages roughly $5 trillion in revenue for 1,500+ customers, and merged with Salesloft in December 2025. Aviso is smaller, with an estimated $37M ARR in 2025.
Aviso markets itself that way, shipping a No-Code Agent Studio, an orchestrator called MIKI, and role-specific AI Avatars in 2025. Clari offers automated pipeline inspection and predictive signals but frames itself around trust and roll-up accuracy more than autonomous action.
Teams that want AI to execute repetitive GTM tasks and are comfortable handing more decisions to software - often at a lower per-rep cost than Clari.
Larger enterprises that prioritize mature roll-up forecasting, native Salesforce integration, and a broad, acquisition-built platform, and can absorb a longer implementation.
