Index Ventures Interview: The Screen, the Case Rounds and the Fit Round

Index Ventures did not start out as a venture capital firm. It began in Geneva in 1976, when Gerald Rimer set up Index Securities, a bond-trading business with nothing to do with startups or technology. His son Neil went to work there in 1992, and four years later Neil, together with David Rimer and Giuseppe Zocco, spun a technology-investing arm out of the family firm and gave it its own name: Index Ventures.

Three decades on, that Geneva bond desk has become one of the best-known venture firms in the world. Index has raised $15 billion since 1996, backed Skype, Deliveroo, Revolut, Figma, Discord, Wise, Datadog and Anthropic, and now runs three parallel fund families out of offices in London, San Francisco and Geneva, plus New York and Jersey. Few firms in venture capital can draw a straight line from a completely unrelated family business to a portfolio like this one.

This is the story of how that happened: every fund Index has raised, what it actually invests in today, who runs it, and how hiring works for anyone hoping to join.

How Index Ventures Hires, and What the Interview Looks Like

Index runs a small, structured graduate pipeline rather than an open junior door, so the practical question for a candidate is which programme is open and what it asks for.

How Index Hires

Index's own openings run through Lever, where postings appear rarely and the board sits empty more often than not. The Startup Jobs section on indexventures.com is a separate thing entirely: it lists open roles, including an entry-level filter, at companies Index has funded, such as Anthropic and Datadog, not at Index itself, and it catches out plenty of candidates who assume otherwise.

When a role does open, Index's own postings ask for real depth. Its Applied AI Investor opening in 2025 wanted two to five years of operational experience at a fast-growing technology company and real familiarity with large language models, not a fresh graduate profile. Older postings describe a different, longer track: a two-to-three-year Associate Program for pre- or post-MBA candidates who rotated across London, San Francisco and Geneva.

Candidates who have been through Index's process describe it moving from broad to specific rather than testing the same thing twice: an early conversation on judgment and motivation, followed by case-style discussions closer to how the investment team actually evaluates a deal, and a final round with partners where fit matters as much as analytical horsepower.

• An early screen on motivation and general reasoning, often the shortest round of the process
• One or more case-style conversations, working through how a real deal gets evaluated rather than abstract puzzles
• A final round with partners, where a candidate's view on the firm's own thesis carries real weight
• For investment-track roles, a written component that rewards a specific, sourced opinion over polish

None of that is unusual for a multi-stage venture firm. What makes it worth preparing for specifically at Index is the final round: a partnership this small, running three fund families across five offices, wants to know a candidate has an actual opinion on where the firm's thesis is heading next, not just a tidy summary of where it has already been.

From a Geneva Bond Desk to a Global Venture Firm

An opinion on where the thesis is heading needs the story of how it got here, and that story starts a long way from technology. Gerald Rimer founded Index Securities in Geneva in 1976, years before venture capital was a term most Europeans would have recognized. It was a bond-trading business, not a technology investor, built to serve wealthy families and institutions in a city known for private banking rather than startups.

It stayed that way until 1992, when Gerald brought his son Neil into the firm to build something new: a technology-investing arm inside a business that otherwise had nothing to do with technology.

The Partners Who Built It

Four years later, in 1996, Neil Rimer, David Rimer and Giuseppe Zocco spun that arm out as an independent firm and called it Index Ventures. Neil had already spent time at Montgomery Securities in San Francisco, giving the new firm an early foothold in Silicon Valley's way of doing business well before most European funds had one.

Giuseppe Zocco arrived after several years consulting at McKinsey across Europe, and brought an operator's instinct for how a growing company actually breaks. Danny Rimer, Neil's brother, joined in 2002 and opened the firm's London office, and remains a partner on the investment team today, three decades after his father's bond desk first put the Rimer name on a Geneva letterhead.

For its first six years, Index operated out of Geneva alone, a single-city European seed investor at a time when most of the capital in technology still sat in Boston and Palo Alto. London changed that: opening a second office there in 2002 put Index inside a market that would go on to produce Wise, Revolut and Depop, and marked the point where the firm stopped being a Geneva curiosity.

The First Big Bet

The new firm's first big swing paid off almost immediately, and twice over. Index backed Skype, the Estonian internet-calling startup, in one of its earliest funding rounds, and stayed close to the company through two changes of owner over the following decade.

Sold to eBay, 2005

$2.6bn

Bought back, 2009

$2.75bn

Sold to Microsoft, 2011

$8.5bn

Not an evenly spaced sequence, four years then two, which is exactly why it is shown as three snapshots rather than a trend line.

San Francisco became a second office in 2011, and New York followed in 2022, turning a Geneva-born, London-anchored European seed investor into a firm spanning ten time zones. Index describes its reach today as covering twenty-four of the world's top thirty tech ecosystems, from San Francisco to Tel Aviv.

Every Fund Index Has Raised

Index's early fund sizes come mostly from press coverage rather than firm pages; the more recent ones are precisely dated on Index's own site. The shape across three decades is simple: fund sizes climbed steadily through the 2000s and the 2010s, and then the firm stopped raising a single flagship altogether.

Fund IV, in 2007, is the clearest early sign of Index's cross-border ambitions: a fifth or more of it was earmarked specifically for Israeli companies at a time when few European funds looked past their own borders. The 2014 early-stage fund arrived just as European venture was starting to shake off the aftershocks of the financial crisis, and Fund VII, in 2017, was the last flagship vehicle Index raised before it split its model in two.

The fund table also tells a quieter story about where Index sees its own center of gravity. Its early funds, through 2017, are denominated in euros, raised from a largely European base for a largely European portfolio.

From the 2021 restructuring on, every fund is priced in dollars, matching a partnership that by then had a full decade of San Francisco operations behind it and was about to add New York. The currency on the fund itself tracks the firm's drift from a European seed shop toward a transatlantic one more plainly than any press release does.

That 2024 raise is the one behind Index's headline figure: the firm has raised $15 billion since founding. It followed up in 2026 with another $2 billion spread across its seed, venture and growth funds, marking its thirtieth year of investing and its most active two-year fundraising stretch to date.

How Index Is Built: One Partnership, Three Fund Families

Since 2021, Index has run three fund families side by side rather than raising one flagship vehicle every few years. Origin writes the earliest checks, Venture leads Series A and B rounds, and Growth backs companies at Series C and beyond. One partnership manages all three: the same team that leads a seed round can still be in the room years later when a company is preparing to go public.

The firm keeps offices in San Francisco, London, New York, Geneva and Jersey, without naming a single headquarters among them. That is unusual for a firm this size, most of which pick one city and call the rest satellites, but it fits a firm whose founding partners were split between Geneva and San Francisco from the start and whose second office, London, has carried as much weight as either one since 2002.

Every fund Index has raised is a standard fixed-life vehicle, closed after a set number of years rather than run as an evergreen pool of capital. When Index Origin II raised in 2022, a partner described its investor base as spanning medical, educational and mission-driven institutions, with no single anchor investor behind it, the kind of quietly diversified limited-partner base that lets a fund keep raising through a downturn without one backer's mood swinging the outcome.

Jersey is the fifth office on that list, and the one most likely to puzzle a candidate who assumes every address on a venture firm's contact page is a place partners sit and take meetings. Channel Islands entities are a common home for the administrative and legal plumbing behind European private funds, a detail that says more about how cross-border capital gets structured than about where any Index partner actually works day to day.

What Index Believes

Index describes its own selection process in blunt terms: "We invest in who you are, not just what you do." That has been the firm's stated approach since well before the Origin funds existed. What changed in 2021 was building the machinery to act on it at every stage, not only at the Series A and B rounds Index built its early reputation on.

The sectors have shifted with the decades, and the portfolio reads like a timeline of what mattered in European and American technology at each point. Index's early bets ran through consumer internet and communications software, Skype among them, and into the marketplaces and social products that defined the 2010s, Discord and Roblox among them.

The years that followed added fintech and payments, Wise and Adyen among the names Index has backed there, then security and infrastructure, where Wiz and Datadog sit. More recently the firm has backed AI companies at scale, including a 2025 round in Anthropic that valued the company at $183 billion, a notably late-stage entry for a firm built on first checks.

What that adds up to, in Index's own pattern of hires and bets:

• Founder quality over a fixed sector thesis or market-size threshold
• One partnership investing across geography, rather than separate regional teams
• A willingness to write the first check and stay through IPO, board seat included
• A thesis that moves with the decade, from consumer internet to fintech to AI infrastructure, rather than staying fixed to whatever made the firm's name

The clearest recent evidence of that reach is Sahir Azam, who joined as a partner in August 2025 after nearly a decade at MongoDB, most recently as its chief product officer, brought on specifically to invest in AI, data and security infrastructure rather than to cover a geography the way earlier partner hires often did.

The Portfolio, Told as a Narrative

Index's own materials return to a consistent set of names, and together they trace an arc from communications software to fintech to today's infrastructure and AI bets. Skype was the proof of concept: an early, unglamorous bet on European internet infrastructure that turned into one of the decade's biggest tech exits, twice over.

By its own last count, in 2024, Index had backed 108 companies that reached a $1 billion valuation, 23 that passed $10 billion, and had taken 57 public.

108

companies past $1bn

23

companies past $10bn

57

taken public

Read together, the list is less a grab-bag than a fairly clean line: consumer software and communications built the firm's early reputation, fintech and security carried it through the 2010s, and AI infrastructure is where its newest checks are going.

Discord is a useful example of how long an Index bet can run before it pays off. The firm backed the chat platform years before it became a mainstream product used well beyond gaming communities, and it remains privately held, a reminder that not every name on this list has reached an exit yet, whatever its eventual outcome turns out to be. Roblox, by contrast, already went public, giving Index a second consumer-platform IPO alongside Figma's.

Anthropic sits apart from the rest of that list. Index's earlier bets, Skype included, were first checks into companies nobody outside the founders' own circle had heard of yet. The 2025 round into Anthropic, at a $183 billion valuation, was the opposite: a growth-stage commitment to a company already recognized as one of the most consequential AI labs in the world.

It says less about Index discovering something early and more about a firm unwilling to sit out the biggest platform shift of the decade, even at a price a seed-stage investor would never have paid for Skype back in the early 2000s.

Naming the Losses: Songkick

A portfolio page that lists only Figma, Wiz and Revolut reads like marketing, not research. Index also backed Songkick, a London concert-discovery and ticketing startup, from a $4 million round in 2008 through a $16 million round in 2015 alongside Sequoia Capital. It is one of the clearest losses in the firm's history, and it rarely makes it into any writeup of Index at all.

Songkick raised roughly $60 million in total before its business came apart. In July 2017, Warner Music's parent, Access Industries, bought only its brand and discovery-app assets, leaving the ticketing business, Songkick's actual core, to shut down that October. A $110 million legal settlement from Live Nation and Ticketmaster followed in January 2018, though by most accounts it fell well short of what Songkick could have been worth as a going concern.

The Last Two Years

Index's most recent stretch has been its busiest. Figma, seeded by Danny Rimer years earlier, went public in July 2025 at a $56 billion valuation. Google acquired Wiz that same year for $32 billion, and Sahir Azam joined the partnership in August 2025 to lead AI, data and security infrastructure investing.

Index took part in Anthropic's 2025 round at a $183 billion valuation. A 2026 secondary sale valued Revolut near $115 billion, and Index closed another $2 billion across its seed, venture and growth funds the same year.

Taken together, those six events say more about where Index is placing its bets today than any single fund announcement: two exits from its consumer and infrastructure era, a late-stage entry into the biggest AI company on the market, and fresh capital arriving right as its older seed bets are reaching the public markets.

Who Runs Index Now

Neil Rimer, David Rimer and Giuseppe Zocco are still the names behind the firm's founding, and Danny Rimer, Neil's brother, has been a partner since 2002. He led Index's seed investment in Figma, sat on its board through the company's 2025 IPO, and was named to Forbes' 2025 Midas List Europe as a result.

Alongside them, Index's own team pages name a wider bench of investment partners across its five offices, including Jan Hammer, Martin Mignot, Nina Achadjian, Shardul Shah, Carlos Gonzalez-Cadenas, Vlad Loktev and Hannah Seal. Some lead European deals out of London, others cover Silicon Valley and New York, and it is a far wider group than the three founders' names still attached to every history of the firm.

The most recent high-profile addition is Sahir Azam, who joined as a partner in New York in August 2025 after leading product at MongoDB, brought in specifically to invest in AI, data and infrastructure. Adrianna Ma, an operating partner who previously worked at General Atlantic and Morgan Stanley, runs the firm's own finance, legal and investor-relations functions, the kind of role that rarely makes headlines but keeps a firm this size running across five time zones.

Index has also been a source of founders elsewhere in venture capital. In 2016, Saul Klein and his father Robin Klein, both former Index partners, left to launch LocalGlobe, now a well-known firm in its own right, a reminder that Index's influence on European venture runs beyond the companies it has directly funded.

What a Strong Answer Contains

• Specific, sourced portfolio knowledge: Figma's IPO, Wiz's sale to Google, Skype's two exits
• Fluency in the firm's own numbers: $15 billion raised since 1996, three fund families since 2021
• One named loss, such as Songkick, rather than only the highlight-reel wins
• A view on where the thesis has moved, toward AI and infrastructure, not just where it started
• A specific, recent event, Revolut's 2026 secondary or the Anthropic round, rather than relying only on older names
• Clarity that Startup Jobs and Medicxi both sound like Index but are not where you apply or what you'd be joining

The Fit Round: Why Index, Specifically

A generic "we back great founders" answer is available to anyone who spent ten minutes on the homepage. A stronger one draws on the structure: a single partnership that can lead a seed round and still be in the room at IPO, built by a family that started in bond trading rather than banking or engineering.

A candidate who ties that structure to a specific company, a Figma or a Wiz moving from an early check to a growth-stage one under the same roof, is showing they understand why Index is built the way it is, not just that the portfolio is impressive.

The same instinct applies to the thesis question: naming the shift from consumer internet to fintech to AI infrastructure, rather than reciting whichever sector is loudest this year, signals someone who has read the firm's actual history rather than its current homepage.

It also helps to have a view on the firm's geography, since Index rarely frames itself as either European or American. A candidate who can point to Skype and Wise as evidence of a European seed-stage instinct, and to Anthropic and Scale AI as evidence of a Silicon Valley growth-stage one, is describing the same firm two different ways, which is closer to how Index actually talks about itself than picking one identity and defending it.

How to Prepare, in Order

1. Read Index's own 2024 and 2026 fund announcements directly, and be able to state how much the firm has raised since 1996.
2. Know the arc from Skype through Figma, Wiz and Anthropic, and have one named loss ready, such as Songkick.
3. Understand the Origin, Venture and Growth split, and why one partnership runs all three.
4. Check the Lever page yourself before assuming a role is open; postings appear rarely and without a fixed calendar.
5. Do not use Startup Jobs to apply to Index itself; it is a board for the firm's portfolio companies, not for Index's own team.
6. Know the Medicxi split if life sciences comes up in conversation.
7. Bring one dated, recent event, such as the Revolut secondary or the Anthropic round, rather than defaulting only to Skype-era comparisons.
8. If asked about headquarters, answer with the ambiguity rather than picking a city; Index itself does not name one.

The Bottom Line

Index Ventures has raised $15 billion since 1996, on top of a portfolio that runs from Skype's two exits through Figma's IPO, Wiz's sale to Google and a growth-stage bet on Anthropic. It got there without being built the conventional way: a bond-trading family business in Geneva, not a bank or a fund of funds, is where the firm's money and its instincts both come from.

A candidate who can speak to that arc, and name a loss like Songkick alongside the wins, is doing more than reciting the homepage. Index's own hiring is quiet, and its Startup Jobs page is not what it looks like, but the firm publishes enough about its funds, its portfolio and its history that reading carefully gets a candidate further than most of the room.

That dual identity, a Geneva founding with a Silicon Valley instinct built in from Neil Rimer's earliest days at Montgomery Securities, is arguably the most distinctive thing about the firm, more so than any single company in the portfolio. It is also the easiest thing to miss for anyone who has only read the current homepage rather than the thirty years behind it.
