Conversations with venture capital investors: how they decide what to invest in, what they look for in founders and a thesis, and how the world looks from the fund's side.
From pre-seed and building a thesis about the future, to sectors like B2C and health tech, and what's actually worth building now.

At the earliest stages investors back the team, not the idea. Renana Ashkenazi of Grove Ventures calls the team the single most important ingredient, because the market, the competition and the technology are still unknown and keep shifting. She looks for people who are energized rather than paralyzed by chaos, and who can make hard calls without all the data.
Aviad Harel of Team8 breaks it into three hats a founding team must cover: technology, product and go-to-market, whether in one person or three. Above all he wants founder-market fit, a deep familiarity with the domain that produces real intuitions. Navot Volk of GroundUp prefers teams over solo founders, people who live the problem and understand why others failed at it.
Nicole Priel, speaking during her time at Ibex Investors, put it this way: she backs founders with no alternative, who would build the company in any macro climate, not wannabes chasing the next-Zuckerberg story.
A good idea isn't enough; investors want to know why now. Navot Volk argues that almost every idea has already been thought of, so what separates a real opportunity is timing: a shift in technology, market, user behavior or the cost of building. In his words, there are no bad ideas, only the wrong time.
Team8 builds the thesis before there is a company. Aviad Harel explains that a good thesis has to pass through three worlds, the problem, the solution and go-to-market, and that theses come in two kinds: solving an identified problem, which is systematic work, or predicting a new future, a longer play with huge upside. Now that building is cheap and fast, the hard part is knowing what to build, for whom, and why now.
Nicole Priel of Kinetic Capital makes the Why now case for consumer: low capital requirements, high scalability and a short path to revenue, riding the AI wave. She also argues you don't need to be first to market, and that it can even hurt, since early players educate the market and the next entrant arrives at a better point in the hype cycle.
The bar for raising has gone up: investors expect evidence, not just a deck. Aviad Harel sees founders arriving with a working prototype at the very first meeting, and notes that if you can build fast, you're also expected to show traction and revenue fast. Navot Volk expects founders to do everything possible without money first: research, user conversations and design partners.
Renana Ashkenazi audits the quality of market validation, not just its conclusions. She asks who you spoke with, which types of companies and personas, what you asked and how, and she even prefers there be no working product yet, so she knows the research was real. Nicole Priel, during her Ibex days, suggested two cheap ways to validate: a landing page with a few hundred dollars of ads and a deliberately high-friction form, or an expert network to reach hard-to-get customers.
In heavier sectors the bar is higher still. Talor Zaks of eHealth Ventures says the era of investing in dreams is over, and that most US funds won't take the meeting before roughly $2 million in revenue.
Navot Volk of GroundUp mainly backs teams rather than solo founders, people who live a real problem and understand why others failed at it. He expects them to do what they can without money first, research, user conversations and design partners, and to articulate clear, fast value for the user, not just a roadmap. Go to the episode
According to Aviad Harel of Team8, founders now show up far more prepared, often with a working prototype at the first meeting rather than just a deck. AI shortens build time, but it also raises the bar: if you can build fast, you're expected to show traction and revenue sooner. Go to the episode
Renana Ashkenazi of Grove Ventures doesn't ask what you learned from the market; she asks who you spoke with, which types of companies and personas, what you asked and how. She won't take bottom lines at face value since they're open to interpretation, and she prefers there be no working product yet so she can tell the research was real. Go to the episode
Nicole Priel, during her time at Ibex Investors, suggested two methods: a landing page backed by a few hundred dollars of Facebook or Google ads with a deliberately high-friction form that proves real demand, or an expert network, paying to reach potential customers who are hard to get through normal channels.

Nicole Priel of Kinetic Capital believes not, and says being first can even hurt. Early players pay to educate the market, and whoever follows harvests an already-educated audience at a different point in the hype cycle. Her example is cloud security, where most of the value was created almost two decades after the cloud appeared. Go to the episode
Talor Zaks of eHealth Ventures explains that the 2021 bubble was followed by bitter disappointment, and investors have pulled back to mostly supporting their existing portfolios. He says most US funds won't take the meeting before roughly $2 million in revenue, and the era of investing in dreams is over: you need to bring a working business. Go to the episode
Aviad Harel
Key takeaway: Building a product has become cheap and easy — so the real challenge has shifted to knowing what is right to build, for whom, and why now.
Navot Volk
Key takeaway: "Why Now" matters more than the idea: almost every idea has been thought of — the question is why it can work right now (technology, market, user behavior, cost of building).
Nicole Priel
Key takeaway: B2C is a clear venture play — low capital requirements, high scalability, and short time to revenue: you can ship a product and see paying customers within weeks.
Renana Ashkenazi
Key takeaway: A sense of capability is transferable: in any domain where you've built up confidence, you can import it into new, frightening areas — from work to parenthood and back.
Talor Zaks
Key takeaway: The American healthcare system pays 4–5 times what the Israeli healthcare system pays for every procedure and gets worse results — this gap generates most of the global opportunities in healthcare.
Nicole Priel
Key takeaway: Nicole looks for founders with "no alternative" — the kind who will build the company in any macroeconomic climate, not the "wannabe" who just wants to be the next Mark Zuckerberg.
