Aviad Harel | Team8 | How to Build a Thesis About the Future Worth Millions
Host: Eyal David · Guest: Aviad Harel
In this episode
- 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.
- A good thesis must pass through three worlds: the problem space, the solution space, and go-to-market — none of them optional.
- There are two kinds of theses: solving an identified problem (systematic work) versus predicting a new future (a longer play with enormous upside).
- A founding team needs to wear three hats — technology, product and go-to-market — alongside genuine founder-market fit.
- A big vision has to be tied to clear first wins; the market — not the founder — knows best, so real friction with customers as early as possible is critical.

Episode Description
Aviad Harel, Managing Partner at Team8 and previously a co-founder of Sisense, on how to build startup theses at the earliest stages — before product, traction or revenue. The conversation moves from resilience lessons at Sisense, through Team8's foundry process, to how founders should think about AI, agents, go-to-market, validation and founder-market fit in a world where you can build faster — but where results are expected faster too.

Selected quotes
“Look, Aviad, the only thing you did well was not die long enough.”
“In the AI era you see founders showing up with products — at minimum with working prototypes. That's a paradigm shift.”
“Nobody wants to end up with a product looking for a market.”
Questions & answers
How does Team8 build and maintain investment theses?
The Enterprise group keeps 4–5 open theses each year and invests millions of dollars in building and validating them. Every thesis moves through three stages — the problem space, the solution space, and go-to-market — with product, strategy, biz dev and product marketing people helping to get real friction with the market. Theses are swapped when needed, and a significant share of companies actually come from founders bringing their own thesis.
What has changed in expectations from founders in the AI era?
According to Aviad, founders today show up far more professionally — usually with a working prototype already in the first conversation, not just slides. AI dramatically shortens build time and build-test cycles, but at the same time raises the bar: traction and revenue are expected earlier, because if you can build fast, results are expected fast too.
What is the difference between a problem-solving thesis and a future-predicting one?
A problem-solution thesis identifies an existing problem, validates it (a demand test) and builds a solution for it — relatively systematic work. A future-prediction thesis (like Uber, Tesla, SpaceX) imagines a new world and derives which elements need to be built; it's a longer, more complex play, but when it succeeds the upside is enormous.
What does Team8 look for in a founding team before investing?
Completeness across three necessary hats — technology, product and go-to-market (in one person or three); working in areas the fund knows; DNA fit and a sense of partnership; and above all founder-market fit — deep, non-linear familiarity with the domain that yields real intuition.
How many customers do you need to talk to for validation?
There's no magic number. You need enough to get insight about the market and not just a single customer, covering different types of organizations and roles — Israeli and non-Israeli, enterprise and Fortune 500 and sometimes small companies too — talking to the CEO, CTO, VP R&D and developers as needed.
