How to Get Funded by Diffusion: A $1.25 Billion AI Fund From Two Former Benchmark Investors

Diffusion, the venture firm started by former Benchmark investors Victor Lazarte and Kris Fredrickson, reported $1.252 billion for its debut fund, Diffusion ONE, and filed a new vehicle, Diffusion V3, LP, at $70 million on October 28, 2026. We covered the larger filing in our October list of new venture capital funds. This profile explains what the filings show, what we could confirm about the founders and their deals, and how AI founders can approach the firm. Where a fact comes from a secondary source, we say so.

What the Filings Show

• Diffusion ONE, LP: $1.252 billion reported sold, in an amendment dated October 9, according to outlets that read the filings
• Diffusion V3, LP: $70.0 million reported sold, filed October 28, with Kristian Fredrickson as the named person
• Original target: Forbes reported in May 2026 that the two investors were aiming for $800 million, so the filing is about 57 percent above that target by our arithmetic

A filing shows that a vehicle exists and what it reports as sold. It is not a final close. We could not find a Diffusion announcement that explains what V3 is, so treat its amount as a filing figure. It may be a companion or side vehicle.

Who Runs Diffusion

Victor Lazarte co-founded Wildlife Studios, one of Latin America's largest mobile gaming companies, before becoming a general partner at Benchmark from 2023 to 2025. Kris Fredrickson began his investing career at Benchmark in 2016 and 2017 before moving to Coatue Management. Both left Benchmark to build their own firm, and they are reported as managing directors on the filings.

What Diffusion Backs

Most coverage describes Diffusion ONE as an AI fund. One outlet describes it as focused on AI and crypto, but we found no second source for the crypto part, so we do not rely on it. Reported deals since the firm launched include:

• Co-leading Harvey's $550 million Series H together with Lightspeed
• Taking part in Etched's $300 million Series C, announced in July

Both are large rounds in AI companies, which suggests the firm writes sizable checks at later stages as well as early ones. We could not confirm its stage focus or typical check size from public sources.

Why the Fund Size Matters to Founders

A $1.25 billion first fund is unusually large for a new firm. For founders, three things follow from that:

• The firm can lead or co-lead large rounds, since it has room to write big checks and still reserve money for follow-ons
• It needs large outcomes to return the fund, so it will look for companies that can become very valuable and not for modest exits
• It is likely to compete with established firms on price, which can raise valuations in hot AI rounds

Who Diffusion Is a Fit For

• AI application and infrastructure companies with strong early traction that need a large lead check
• Founders in a competitive round who want a second lead with deep operating experience
• Teams that want investors who have backed other AI breakout companies

It is less obviously a fit for very early idea-stage companies, since the deals we found are larger rounds.

What AI Investors Look For

Expect questions about what you own that a bigger model provider cannot copy, how fast revenue grows and how much compute costs you. Be ready to show retention, gross margin after model costs and a plan for what happens if your model supplier changes prices.

How to Approach Diffusion

• Get a warm introduction from a portfolio founder, a co-investor or a former Benchmark colleague
• Send a short note with what you build, your growth rate, the round size and why this firm
• Prepare your data room, check your cap table and model your dilution
• Ask whether the firm expects to be the lead investor and what its term sheet usually includes
• If you already have a lead, ask whether Diffusion would co-invest

Questions to Ask Before You Pitch

• Which partner would lead the investment, and who sits on the board afterwards?
• What is the typical check size, and does the firm reserve money for follow-ons in later rounds?
• Which fund would invest in my company, ONE or another vehicle such as V3?
• How does the firm decide on valuation in a competitive AI round?
• What does the team offer after the round, such as hiring help or customer introductions?

What We Could Not Confirm

We could not confirm the firm's check size range, its stage focus, what Diffusion V3 is or the full portfolio. Check Diffusion's own materials for the latest details.
