Karim Busta grew up and was educated in France, graduating from Telecom Paris, and initially worked for large US companies in Europe.
He moved to Silicon Valley at age 35-36, motivated by opportunities and aligned values in American corporate culture, especially around innovation and professional mobility.
He and his wife relocated with an expat contract, initially planning a temporary stay that became permanent after three months.
Karim noted significant cultural differences, especially regarding workplace social interactions and the high-paced, work-centric environment in Silicon Valley compared to France and Miami.

Karim joined Tesla in late 2015 as Head of Global Customer Service, after an intense, multi-stage interview process led by Elon Musk.
The interview involved a high-pressure first impression, an in-depth exploration of prior problem-solving experience, and non-traditional tactics to assess resilience and fit.
Elon Musk’s management style is described as direct, demanding, and intense, with little tolerance for perceived weakness or hesitation. New hires remain under scrutiny even after onboarding.
The environment at Tesla was high-pressure, mission-driven, with a strong sense of mutual support among employees that compensated for the leader’s lack of empathy.
Karim highlighted Musk’s genius in product vision, relentless simplification, and aggressive software integration, citing the Model 3 as a breakthrough example.
Musk’s approach favors speed, risk-taking, and learning from failure (“10 tries to succeed once while competitors are still considering their options”), often making unorthodox product decisions (e.g., glovebox control and steering wheel removal).

Tesla operated without traditional product or marketing teams, focusing on clear, simple strategy communication.
Decision-making was centralized, with clear priorities aligned to Elon Musk’s vision (e.g., getting Model 3 to volume production).
Critical issues, such as safety recalls, were handled rapidly and directly, reflecting the principle that company survival depended on absolute reliability.
Employees internalized the company’s mission and urgency, with little room for political maneuvering or personal agendas.

After leaving Tesla, Karim joined Lyft, initially attracted by its culture and leadership’s perceived benevolence.
At Lyft, despite hiring experienced operators from companies like Tesla, replicating Tesla-level results was hampered by differences in organizational culture and employee mindset (“hardcore/all-in” spirit was often absent).
Lyft’s growth ambitions were undercut by what Karim saw as employee complacency, a more risk-averse approach, and a lack of existential pressure compared to Tesla or Uber.
The IPO process and subsequent cost-cutting at Lyft marked the end of its distinct, driver-centered culture, with increasing resemblance to Uber.

Karim was recruited by Softbank Vision Fund as an operating partner, working between investments and companies in crisis.
He described Vision Fund founder Masayoshi Son’s long-term, instinct-driven investment philosophy, focusing on AI and large, often risky bets.
Karim intervened at GetAround (following its acquisition of French company Drivy) during a financial crisis, restructuring and guiding it through COVID-19 by identifying new user segments and cutting costs.
He noted that excessive capital can lead to inefficiency and loss of urgency, as seen at GetAround and other startups.

Karim co-founded venture studio DVX, aiming to address waste and inefficiency he observed in traditional VC/startup models.
DVX’s approach is to quickly validate or terminate projects, concentrating resources on the most promising and actively engaging as co-founders/operators.
The studio model involves cycles of company-building, emphasizing early-stage “builder” CEOs, and transitioning to growth-oriented leadership as companies scale.
Finding CEOs for startup studios is less challenging in the US due to a larger pool of experienced “0-to-1” entrepreneurs, and the model allows for shared/founder equity tailored to each situation.
Karim argues that being founder-operators and maintaining deep engagement makes the studio’s equity allocation attractive to downstream investors, even when non-traditional.

Karim observes that the startup ecosystem in France/Europe is hindered by less available capital, risk-aversion, and talent shortages among “hardcore” staff.
He believes some cultural traits are difficult to replicate, such as the Silicon Valley tolerance for failure, speed, and existential motivation.
While entrepreneurship exists in France, the scale, intensity, and willingness to sacrifice for company success are less common.

Karim Busta left Tesla and later Lyft at his own discretion — driven by self-assessment of contribution, burnout risk, and organizational fit.
Softbank declined to provide further funding directly to GetAround without intervention and cost control — rationale: prevent further waste and clarify company viability before additional investment.
DVX studio model preference for early, active involvement and rapid go/no-go decisions — rationale: maximize resource efficiency and avoid sustaining doomed projects.

Will the DVX venture studio model continue to attract institutional investment as it matures, especially with its non-traditional founder equity split?
Can the “hardcore” Silicon Valley startup culture be cultivated in Europe with current structural and cultural differences?
How sustainable is the transition model of rotating “0-to-1” CEOs as companies scale and mature?
