Delian Asparouhov on Founders Fund, Conviction and Building Companies

Founders Fund partner and Varda Space Industries co-founder Delian Asparouhov offers strong views on Europe, founder leadership and venture capital. His political predictions and allegations about an executive’s removal are personal, contested assertions, not independently established facts.

Asparouhov tells Harry Stebbings that Bulgarian heritage and growing up in the United States left him feeling not entirely at home in either place. Visiting a cousin in Bulgaria helped him see some traits he considered unusual in America as familiar in his family’s culture. He credits his family with a happy childhood.

He says he later identified more strongly with the United States and Silicon Valley. He predicts Western European decline and a stronger trajectory for parts of Eastern Europe, citing growth, entrepreneurship and regulation. These broad political and economic claims are his opinions and extrapolations, not established forecasts.

He points to a Bulgarian satellite company as an example of talent and energy, and speculates that some Eastern European states could eventually leave the EU. Stebbings argues that European culture, heritage and hospitality remain valuable economic assets. Neither gives evidence sufficient to establish the proposed political outcome.

Asparouhov offers a “great man” and family theory of history, arguing that multigenerational families can sustain institutions and projects. He sees enduring technology families emerging in the US and criticizes European attitudes to inherited wealth. This is his interpretation of history and social policy, not a demonstrated account of European decline.

Stebbings challenges him on American healthcare, homelessness and gun violence. Asparouhov responds that the American system permits both severe downsides and exceptional entrepreneurial outcomes, citing an approximate comparison of space launches. His proposed link between social harms and innovation is speculative; the interview does not establish that one requires the other.

He recalls interning at Square in 2012 and watching COO Keith Rabois analyze a growth slowdown using cohort data. According to Asparouhov, seasonal merchant activity explained a weak July and subsequent growth supported the analysis. The episode showed him that mathematics could inform business decisions.

After deciding to leave MIT, he emailed Rabois and began meeting him. He says Rabois later explained that colleagues tolerated his disruptive office habits without complaint, which made Rabois curious about his work. Their relationship grew through regular lunches and a soccer team; this is his personal recollection.

Rabois’s “Hollywood” analogy influenced Asparouhov: begin with a strong vision, identify major risks and assemble the right people, as a studio casts a film. He says Varda followed that approach rather than waiting for early customer feedback. His account concerns a company he co-founded and has a direct interest in.

Stebbings notes the tension with advice to listen closely to customers. Asparouhov thinks iterative feedback may suit incremental software, but argues some ambitious technology companies begin with a founder’s vision. This is a strategic preference and retrospective interpretation, not evidence that customer research is unhelpful.

He says Rabois looks for a founder’s distinctive “spark,” which can appear in a skill outside the company’s immediate field. Stebbings adds his own belief that early entrepreneurial activity and immigrant backgrounds correlate with success. Neither provides a controlled comparison establishing those correlations.

As a junior investor at Khosla Ventures, Asparouhov tried to do work senior partners lacked time to do. He recalls studying Sword Health’s scientific material and quickly flying to Portugal to meet the team, then helping bring its founders to the partnership. His positive account concerns a company in which he and his firms invested; clinical effectiveness is not established here.

He urges junior investors to meet founders in person and find ways to create value before they have a senior partner’s reputation. Early on, he recommends meeting a broad range of founders to develop judgment, then becoming selective about investments. These are his career heuristics, not guaranteed routes to success.

He describes five venture skills: sourcing, selecting, building internal support, winning the founder and helping after investment. He argues juniors should first distinguish themselves in one or two areas rather than trying to be average at everything. He chose aerospace expertise and support for existing portfolio founders.

He says assisting a portfolio founder helped him earn a reference that supported another investment. Some Founders Fund partners prefer to back strong founders and remain largely hands-off; Asparouhov says he disagrees and enjoys contributing after the check. Both approaches are described from inside the firm.

His biggest missed follow-on, he says, was a proposed $10 million investment in Sword at a $100 million post-money valuation around late 2019. He believes he went directly to Peter Thiel without building enough support among colleagues. He estimates the position could later have been worth $300 million; this is a hypothetical mark, not realized proceeds, and dilution and terms are not specified.

He says a better route is to seek out colleagues most likely to challenge a thesis and build conviction before approaching a decision-maker. He describes Founders Fund’s process as taking the path of most resistance. His description is a participant’s account of internal practice.

Asparouhov praises Sequoia, Andreessen Horowitz and historically Benchmark, and claims Founders Fund’s decisions produced superior results over the preceding five years. The interview does not provide comparable fund-level return data or methodology, so the performance comparison remains his claim.

He would hire more junior investors to develop the firm’s next generation, noting that several current general partners started junior. He says the small investment team, close relationships and shared economics encourage collaboration without allocating credit deal by deal. This is his account of firm culture and incentives.

He distinguishes Founders Fund’s structured voting thresholds for different check sizes from its less formal meeting schedule. A partner who cannot persuade one decision-maker can seek another’s support, he says. He contrasts this with consensus voting and with firms where senior partners may dominate despite formal votes.

He recalls losing a wildfire insurance technology investment after the founder chose another firm, and thinks distance and timing limited their ability to meet. He also reflects that an investor can feel entitled to follow-on allocation. A contractual pro rata right depends on its terms; his point concerns relationships and expectations rather than a claim that legal rights do not exist.

Asparouhov argues public disagreements can help founders understand investor character. He harshly criticizes Bill Gurley’s role in Travis Kalanick’s departure from Uber. The interview presents his account without the other parties’ response or sufficient evidence to establish the details or motives.

Stebbings asks what happens when investor liquidity needs diverge from a founder’s interests. Asparouhov emphasizes Founders Fund’s founder-friendly approach and says founder-led companies can produce exceptional outcomes. Stebbings counters that founders should not have an unconditional right to stay if they fail employees or the company.

Asparouhov speculates Uber could have been worth more under Kalanick and claims the circumstances of his removal were improper. He says Kalanick committed no crime and describes a pressured signing. These are disputed allegations and a counterfactual; the interview does not establish their accuracy or what Uber would have been worth.

Stebbings cites Satya Nadella as a professional CEO who took major risks. Asparouhov responds by comparing Microsoft with founder-controlled Meta and predicts founder-led companies can take larger risks. His claims about benchmarks and hypothetical company outcomes are opinions, not verified comparisons or guarantees.

He says Peter Thiel is skilled at framing arguments and that Founders Fund encourages disagreement with him. As an example, he recalls strongly opposing a potential hire and asking a critical colleague to meet the candidate. The anecdote is his description of how dissent can work within the partnership.

Asparouhov says he differs from partners who believe top founders need little help: he aims to meet portfolio leaders regularly and attend board meetings. He believes investors can harm companies when their own anxiety about a quick valuation increase or liquidity drives short-term pressure.

He also warns that operational advice can become stale when an investor has not worked in a company for years. He credits deeply involved operators with retaining useful context. His rule of thumb about three to five years is a personal view, not a measured expiry date for advice.

Running Varda helps him source and evaluate aerospace opportunities, he says, by giving him direct relationships with people in the field. He recounts using those relationships to diligence an investment quickly and says he has won opportunities since founding Varda. His claimed track record and advantages are self-reported.

He sees no consistent relationship between a deal’s popularity and its eventual outcome, comparing the less competitive Sword Health round with a competitive Ramp seed round. Both are investments in which he has an interest. The small set of examples does not establish a general statistical relationship.

He says Varda has not always chosen the highest valuation offered, preferring terms he considers sustainable. Price matters if it pushes a company far outside a reasonable range, though he is willing to pay for exceptional founders. His recollections of round pricing and judgments are approximate and reflect his investment interests.

Asparouhov says aerospace and defense investing went from an unpopular specialty to a crowded theme. He argues capital intensity can create a moat and provocatively claims some software is easy to replicate. Stebbings challenges him with ServiceTitan’s workflows, trust and distribution; Asparouhov concedes brand and distribution matter but maintains that software itself can be copied.

He expects investors to need deeper knowledge of materials, biology and aerospace as capital-intensive industries attract attention. He predicts leading firms may remain prominent but that specialist funds could struggle when a sector falls out of favor. These are competitive predictions from a partner at a generalist firm.

Asked about a post dismissing unmarried, childless straight people over 35, Asparouhov links parenthood to his idea of long-term thinking while acknowledging exceptions. This is his personal and exclusionary judgment, not evidence that unmarried or childless people lack long-term commitment or contribution.

He says he prefers to state his views openly even when others find them offensive. He argues Americans can take their advantages for granted, discusses work intensity and predicts a split between people working less and a highly productive group using new tools. His broad cultural claims and labor forecasts are not established in the interview.

Stebbings disputes Asparouhov’s characterization of European taxation. On finding a partner, Asparouhov recommends avoiding an overly rigid checklist: he once thought his wife needed to be a strong skier, but says compatibility meant being able to be himself. He ranks honesty, physical intimacy, laughter and respect as personal priorities.

He says becoming a father unexpectedly improved his everyday mood and helps him put professional stress in perspective. This is his family experience, not a universal claim about parenting or mental health.

Asked for an untweeted radical thought, Asparouhov speculates that embryo selection, gene editing and space settlement could produce new human species over the next century or more, creating moral and geopolitical risks. These are conjectures, not established scientific predictions or evidence that such speciation will occur.

In quick fire he praises board members, says he is trying to criticize ideas rather than individuals online and recalls being asked by colleagues to reconsider some posts. He sees transparency as useful to founders choosing partners, while acknowledging that he has made enemies.

He says stress and lack of sleep can impair him, so he seeks colleagues who complement that weakness. He credits Varda co-founder Will Bruey with operational resilience. This is a personal comparison, not a recommendation to work on insufficient sleep.

Asked why he is Varda’s president rather than its CEO, he says he believes his co-founder is better suited to the CEO role and that he should focus on his own strengths. He leaves open the possibility that his abilities may change with experience. The interview closes with thanks.
