Valentyn Vakatsiienko

Who they are

Valentyn Vakatsiienko is Senior Engineering Director of Talent at Factorial — he came from Grammarly and ships iOS apps on the side, including 8x3, published on the Apple App Store.

Person

Valentyn joined Factorial in February 2025, when the company was already scaling toward unicorn territory but had yet to close its Series D. He came from Grammarly, where he held an Engineering Manager role — a strong signal that he knows how to build engineering culture inside a product-led, globally distributed company. His current title, Senior Engineering Director of Talent, puts him at the intersection of engineering and people systems, which fits squarely with Factorial's HR-tech product domain. Alongside his employed track, he published 8x3, an iOS app on the Apple App Store — a small but telling signal of hands-on builder instincts that survive seniority. Possibly — his stated interest in distributed systems, LLM/AI in computing, and engineering culture shapes how he structures his teams and evaluates tooling decisions. The through-line is engineering leadership inside high-growth product companies, with a consistent pull toward the organisational and cultural layer of the stack.

Company

Factorial closed a $150 million Series D on June 3, 2026, led by General Catalyst — its first equity investment in the company — with Atomico and Four Rivers also participating, pushing its valuation to $2.5 billion and placing it among the top 20 most valuable scale-ups in the EU. General Catalyst separately committed an additional $540 million through its Customer Value Fund, bringing total capital committed to over $700 million in a structure designed to support growth without cash burn. The strategic context for the raise is a product pivot: Factorial One, an AI-powered unified workspace built around a two-agent model covering HR, finance, and IT management, marks the company's transition from traditional SaaS to what it calls an AI Workforce Operations Platform. Off the back of the round, Factorial announced plans to open a Munich office — identified as its top international growth market — and is actively expanding hiring across sales, customer success, product, marketing, and engineering.

Market

Factorial competes in HRTech against incumbents Workday and Kronos, plus regional players like People Strong — all significantly larger and more entrenched in enterprise procurement cycles. Factorial's positioning as Europe's leading AI Workforce Operations Platform is a direct bet that an AI-first architecture, rather than legacy SaaS retrofitted with AI features, will take share from those incumbents as buyers increasingly demand measurable productivity gains from software spend.

Network

Valentyn's visible network at Factorial centers on his first-week cohort. Ray García and Gregory Bevilacqua are peer Engineering Directors at the company, and Bernat Farrero, Factorial's CEO, was tagged in his first-week post — suggesting early visibility at the leadership level.

How they likely show up

  • Came from Grammarly (a globally distributed, product-led engineering org) → likely comfortable managing remote or cross-timezone teams and expects strong written communication norms.
  • Published 8x3 on the Apple App Store alongside a senior full-time role → builder instincts remain active at the IC level, even in leadership; probably values managers who can still read and review code.
  • Possibly — stated content themes include distributed systems, LLM/AI in computing, and engineering culture → likely evaluates architectural and tooling decisions through a culture lens, not just a technical one.
  • Joined Factorial as Senior Engineering Director of Talent, embedding engineering leadership inside the HR product domain → comfortable with ambiguity at the boundary between people operations and product engineering.
  • LinkedIn post marking his first week tagged the CEO directly → signals comfort operating with upward visibility and an appetite for being known at the top of the org early.

Conversation tips

  • → Ask about the move from Grammarly to Factorial — the shift from a writing-AI product to an HR-AI platform is a deliberate one and he'll have a clear thesis on why.
  • → Reference 8x3 by name — he built and shipped it himself, and noticing it signals you've done more than skim his LinkedIn.
  • → If the conversation goes to AI in engineering, push past the generic — he thinks about LLMs in the context of engineering culture, not just productivity tooling.
  • → He joined during a high-growth moment (Series D hiring push); questions about how he's structuring the Talent engineering org will land better than questions about what Factorial does.

Toolbox

Openers

  • Open on 8x3 — he built and shipped an iOS app to the App Store himself, which is a pointed choice for someone at Engineering Director level; it's a useful signal about how he thinks about ownership.
  • Lead with the Factorial Series D timing — he joined in February 2025, more than a year before the $150M round closed in June 2026, which means he's been building through the pre-raise scaling push and now sits inside a $2.5B company with a Munich expansion underway.
  • Reference the Factorial One product pivot — the shift from traditional SaaS to an AI Workforce Operations Platform built around a two-agent model is the defining strategic bet of his tenure so far, and his role sits directly inside it.

Discovery questions

  1. How does running engineering for the Talent product at an HR-tech company change how you think about recruiting and team design inside your own org?
  2. What did Grammarly's engineering culture get right that you're trying to bring to Factorial, and what are you deliberately leaving behind?
  3. Factorial One is positioned as a two-agent AI workspace — how does that architecture actually change what the engineering team ships day to day versus a traditional SaaS roadmap?

Avoid

Don't treat the Series D as the starting point of the conversation — he joined over a year before it closed and will have a much richer view of what the company was building through the pre-raise period.
