When the founders of Smartly.io grew their advertising automation company past a thousand employees, they ran into the same wall most scaling tech firms hit: the performance review process they built at 50 people did not work at 500. Annual cycles produced disconnected reviews, generic feedback, and tools that added administrative load without telling managers anything they did not already know [ArcticStartup, 2024]. Two of those operators, Kristo Ovaska and Juho Eräste, are now selling the system they wish they had had. Their company, Taito.ai, is a Helsinki-based AI agent that lives inside Slack and is trying to replace the heavy annual review with a steady drip of expectations, feedback, and coaching prompts pushed to managers and their reports in the channels where work already happens [Taito.ai, 2024].
The bet
Taito.ai, named after the Finnish word for skill, sells a Slack-native performance enablement product priced from €6 per user per month [Taito.ai, 2024]. The wedge is the AI agent the company calls Performance Intelligence, which automates goal-setting, 1:1 prep, coaching nudges, and evaluations rather than asking HR to chase managers for forms once or twice a year [Taito.ai, 2024]. The ideal customer profile is reasonably clear from the product surface and the founders' own pedigree: 100 to 1,000-person scale-ups, mostly in tech, that already run on Slack, that have outgrown spreadsheets but find Lattice or 15Five too form-heavy, and where the budget owner is a Head of People or COO rather than a CHRO at a Fortune 500. At €6 per seat, a 400-person company is a roughly €29,000 annual contract, which is a mid-market deal closeable without a procurement gauntlet.
Why it could be big
The category tailwind is real. Performance management software has been one of the most complained-about line items in the HR stack for a decade, and the arrival of LLMs gives a credible technical reason to revisit it: drafting feedback, summarizing 1:1 notes, and surfacing coaching moments are exactly the tasks generative models do well. Accel led the $2.7 million seed in November 2024, and the angel list reads like a Nordic operator who's who: Eléonore Crespo of Pigment, Robert Gentz of Zalando, and Wolt's Miki Kuusi all wrote checks [EU-Startups, Nov 2024]. That cap table matters for two reasons. First, those angels run or ran companies in exactly the 500-to-5,000-employee band Taito is targeting, which means warm intros to design partners. Second, Accel has a track record in European B2B SaaS that suggests they are underwriting more than a seed-stage experiment.

The team and traction
Kristo Ovaska is Founder and CEO of Taito.ai [Crunchbase, 2026]. He previously founded and led Smartly.io, which scaled to several hundred million in revenue and a majority recapitalization by Providence Equity. Juho Eräste, his co-founder and CTO, started Taito.ai in 2024 [Swarmia, 2026] after a stint at Swarmia, the Finnish engineering analytics company [Crunchbase, 2024]. The pairing is unusually well-matched to the problem: Ovaska has lived the pain of running performance cycles across a fast-growing distributed workforce, and Eräste comes from a company whose entire product is about measuring what good engineering work looks like. Customer counts and ARR are not part of the disclosed record, but the product is live, pricing is public, and the company is shipping feature pages for an Expectations Agent and a 1:1 Meetings agent [Taito.ai, 2024], which suggests the roadmap is already past the demo-ware stage.
The honest counterfactual
The bear case is straightforward and worth taking seriously. Lattice and 15Five are entrenched, well-funded, and have spent the last 18 months bolting AI features onto their existing suites. A buyer who already pays Lattice is unlikely to rip and replace for a €6 per seat Slack agent unless the workflow difference is dramatic. The renewal motion at this price point is also unproven: continuous-feedback tools have historically struggled with manager adoption, and if managers stop engaging with the Slack prompts after month three, churn shows up at month twelve. What bulls answer is that Taito is not trying to be a system of record. It is trying to be a system of action that sits on top of Slack, where the work conversation already lives, and the €6 entry price lets a Head of People run a pilot without involving procurement at all. That is a meaningfully different sales motion than Lattice's, and it is the kind of bottoms-up wedge that has worked for other Nordic B2B companies including, not coincidentally, Swarmia.
The realistic competitive set is Lattice and 15Five at the incumbent end, Leapsome and Culture Amp in adjacent territory, and a growing crop of AI-native entrants such as Confirm and Perform. None of those competitors have a Slack-first, agent-driven posture as their primary product surface, which is where Taito is trying to plant its flag.
What to watch
The next twelve months come down to three questions. Can Taito convert the Nordic design-partner pipeline into named logos outside Finland and Sweden, ideally in the UK and DACH where Accel has reach? Does the product show retention numbers good enough to justify a Series A in late 2025 or early 2026? And does the Expectations Agent, which is the company's most differentiated piece, become something managers open on their own rather than something HR pushes them toward? If the answer to the third question is yes, the rest tends to follow.
