Sergey Toporov

Sergey Toporov is a Partner at LETA Capital, an entrepreneur-friendly, data-driven early-stage venture firm founded in 2012. He joined LETA in 2012 as an investment deal scout and was promoted to Partner in 2018, giving him more than a decade in the venture industry. He is based in London and is active in the local tech ecosystem, frequently appearing at demo days and pitch events as a judge and mentor.

Before venture capital, Toporov worked in deep-tech industry, serving as COO at ASK Labs, where he promoted Advanced Process Control (APC) systems — smart control solutions for industrial production in mineral fertilizers, oil refining, and metallurgy. That operating background informs his interest in software that optimizes or replaces inefficient legacy business processes. He studied at Ural State University (named after A.M. Gorky) in Yekaterinburg, Russia.

Over his career at LETA, Toporov reports having closed roughly 40 venture deals worth more than $60M, and says he has reviewed over 7,000 pitch decks — a volume that underpins his blunt, execution-first evaluation style. He also writes and speaks publicly about the venture model, including a 2024 Startups Magazine piece, "What You Should Know About the Venture Fund Business Model."

• Invests at seed through Series B, typically writing checks from ~$300K up to $10M, with a ~$1–5M sweet spot; LETA often leads rounds and is open to co-investors.
• Focus sectors: AI, B2B SaaS, developer tools, analytics/big data, AR/VR/XR, EdTech, AutoTech, and enterprise applications — favoring startups that optimize or replace inefficient business processes rather than hype-driven categories.
• Evaluates on three core elements: obsessed founders, crisp execution, and timing just ahead of the market. In his words: *"The company should be surfing just ahead of the next wave – not already in an overhyped place, but not too early either."*
• Leans toward durable, real-world problems over pure hype, noting that *"people still can't eat AI, travel inside code, or sleep in digital houses."*
• Prizes proof over promises: *"If you can't explain what you're building and why it has a fundamental meaning to exist, no deck will save you."*
• LETA's underlying manifesto looks for traction (paying customers, rapid growth), subscription/high-margin models, and companies capable of delivering 10x+ outcomes; historically not interested in games, e-commerce, or media.
• Has expressed a particular interest in backing female founders.
