VCs in 2026 Want Your Unit Economics, Not Your Vision Deck

According to Kopylkov, this shift reflects a broader recalibration of risk tolerance across the investor class. "Capital became expensive, and suddenly the math had to work on paper before it worked in practice," he explains. The era of growth-at-all-costs is over. In its place, a new investor mindset has emerged—one that prioritizes sustainable margins, capital efficiency, and clear paths to profitability.

The Numbers Tell the Story

The data is unambiguous. Seed-to-Series A timelines have stretched to 774 days—an 84% increase from the 420-day average in 2021. Investors are taking longer to write follow-on checks because they want to see proof, not projections.

Kopylkov breaks it down into first principles: longer runways mean founders must demonstrate unit economics earlier → investors use that extended period to filter for capital efficiency → only companies with proven fundamentals advance to the next stage.

LTV:CAC ratios have become the first filter in due diligence. A 3:1 ratio is now table stakes. Top-performing startups demonstrate 4:1 to 7:1, reflecting both customer value and acquisition discipline.

Citing data from SaaS Capital, Kopylkov notes that every percentage point of retention improvement correlates with a 12% increase in company value over five years. "NRR isn't just a health metric—it's a valuation multiplier," he observes. The median NRR across venture-backed startups sits at 106%, but investors increasingly require 115-120% before considering premium valuations.

The Casualties of the Previous Era

The shift did not happen without consequences. WeWork raised over $12 billion, reached a $47 billion valuation, and filed for Chapter 11 bankruptcy. Hopin raised over $1 billion, peaked at $7.75 billion, and sold for $15 million. Convoy raised over $900 million at a $3.8 billion valuation before ceasing operations entirely.

Kopylkov compares this shift to the dot-com correction of 2000-2001, noting that both cycles saw investors conflate growth signals with business fundamentals. "The difference now is that the correction happened faster, and the lessons are being institutionalized into due diligence frameworks rather than forgotten in the next boom."

These were not obscure failures. They were celebrated companies backed by top-tier investors. Their common thread: growth metrics that masked unsustainable unit economics.

What Investors Now Expect

The conversation in pitch meetings has changed. Vision matters, but it is no longer sufficient.

From an investor's perspective, Kopylkov evaluates early-stage companies by looking at three metrics before anything else: CAC payback period, gross margin trajectory, and net dollar retention. "If a founder can't speak fluently about these numbers, the meeting ends early," he says.

For founders, Kopylkov recommends building a unit economics dashboard before the first investor conversation. "Know your CAC by channel, your payback period by customer segment, your gross margin by product line. These are not metrics to figure out later—they are the foundation of every investor conversation in 2026."

The Capital Concentration Effect

This discipline has reshaped how capital flows. AI and machine learning companies captured 65.4% of all venture deal value in 2025—$222 billion of $339 billion deployed. That concentration reflects where investors see sustainable unit economics: companies building infrastructure, tools, and applications with defensible margins.

Meanwhile, first-time fund formation has collapsed. New funds declined 57% year-over-year in 2024, with just nine firms capturing nearly half of all capital raised.

In his view, this concentration will intensify through 2027 before stabilizing. "The bar for emerging managers mirrors the bar for founders: prove it works before asking for more. We're seeing a flight to quality on both sides of the table."

The Path Forward

The venture market has not closed. It has recalibrated.

Kopylkov sees a silver lining for disciplined operators: "Companies that extended their runway and improved their NRR are raising oversubscribed rounds at higher valuations than their 2021 peers. Discipline has become a competitive advantage."

The good news for founders who understand that unit economics are not constraints but proof of a working business: the opportunity remains substantial. The capital is there. The question is whether the fundamentals are.
