Capital, conviction, and what it really takes to build in uncertainty
The fireside session at the Kissflow office in the World Trade Center, Chennai, was not structured like a typical startup event where ideas are exchanged quickly and forgotten just as fast. Instead, it unfolded as an extended and layered conversation that demanded attention, reflection, and, at times, recalibration of how one thinks about venture capital and entrepreneurship.
Hosted by Idea Pattarai, ‘Better Call Show – Edition 7’ featured a three-hour fireside chat with Karthik B. Reddy, co-founder of Blume Ventures, and was moderated by Aravind Suresh of Mudhal VC. The discussion was followed by an hour-long Q&A session, which allowed the audience to probe deeper into the realities of venture capital, making the overall experience feel more like a detailed exploration than a one-way exchange.
The conversation began with time as its central theme.
Seeing Ten Years Ahead Before There Was an Ecosystem
Karthik’s journey can be traced back to the late 1990s, during the 1999–2000 dot-com boom, when he was based in the United States and had direct exposure to the rapid convergence of technology, capital, and entrepreneurial ambition. This period offered him a vantage point from which he could observe not only what was happening in the moment but also what might unfold over the next decade.
What stayed with him was the ability to think in ten-year horizons and to anticipate how markets, industries, and ecosystems could evolve over time. When he returned to India, he carried with him this long-term perspective, along with a strong inclination to build and support a startup ecosystem that could reflect similar growth and potential.
At that time, India’s startup and investment landscape was still in its early stages, with fragmented angel networks and limited institutional venture capital presence. Karthik’s involvement with the Times Group and his engagement with Mumbai-based angel networks exposed him to the gaps that existed in the system. Blume Ventures, which was formally established in 2010, was therefore not an isolated initiative but the outcome of nearly a decade of observation, participation, and understanding of the ecosystem.
Over time, Blume Ventures played a significant role in formalizing early-stage investing in India and contributed to the emergence of several micro venture capital firms. The contrast is stark when one considers that in 2006, the ecosystem was largely unstructured, and even in 2016, it was still evolving. By 2026, however, India has more than 200 venture capital firms and micro VCs, indicating not just growth but a compounding of institutional maturity.
The Evolution of Founders and Market Expectations
As the ecosystem evolved, so did the profiles of founders entering it. In the early days, many founders emerged from established companies such as Wipro, Yahoo, and Google Labs. This later shifted to employees from companies like Flipkart, Zoho, Freshworks, and Kissflow, which themselves became breeding grounds for entrepreneurial talent.
In the present day, founders come from a far wider range of backgrounds, reflecting the diversification of the ecosystem. However, despite this evolution, one constraint has remained constant, which is the importance of market size.
Founders often present ideas that focus on niche segments, adjacent markets, or new customer categories, but unless there is a clear and credible pathway to building a business worth at least ₹1,000 crore or reaching a billion-dollar valuation, these ideas struggle to align with venture capital expectations. Even products that demonstrate strong user engagement must ultimately prove that they can scale into large markets. This is where concepts such as TAM, SAM, and SOM move beyond theoretical frameworks and become critical tools for strategic planning.
Venture capital, in this sense, is not merely funding innovation but is fundamentally investing in scalable outcomes.
How Venture Capital Actually Works in Practice
Blume’s early investment philosophy was influenced by the frameworks of Andreessen Horowitz and Marc Andreessen, particularly the 40-40-20 model that evaluates market, product, and team. However, Karthik acknowledged that rigid adherence to such frameworks often falls short in practice.
Over the years, Blume Ventures has encountered both successes and failures, with some of its earliest investments still struggling even today. These experiences have led to continuous refinement in how the firm evaluates startups, emphasizing adaptability over fixed criteria.
One of the most critical aspects of evaluation is the evolution of the founding team across different stages of growth, from zero to one, one to five, and five to ten. Each stage requires a different mindset and capability, and founders must be able to adapt accordingly. Additionally, founders are expected to build teams that can eventually operate independently of them.
Karthik pointed out that co-founder exits are a common occurrence, often happening around the third, seventh or eighth year of a startup’s journey. In such situations, the resilience of the organization depends on the strength of its processes, governance structures, and internal culture, rather than on any single individual and the founder (or the alpha founder) is to build all of it!
The Importance of Follow-On Capital
A particularly important consideration in Blume’s investment process is the ability of a startup to attract future investors. When Blume makes an initial investment, it evaluates not only the current potential of the company but also whether subsequent investors will find the opportunity compelling.
This forward-looking approach ensures that the startup has a viable pathway through multiple funding stages. In this context, venture capital is not only about making the first bet but also about ensuring that the company can sustain momentum in the long term.
Building for IPOs and Long-Term Outcomes
Karthik expressed a clear preference for building companies with the potential for public listing rather than focusing solely on early acquisitions. He emphasized that building a company is a long-term commitment that can span up to twenty years.
Regardless of the exit route, whether through IPO or acquisition, the underlying fundamentals remain consistent. Companies must demonstrate profitability, strong EBITDA, and sustainable margins, typically in the range of 20 to 25 percent net profit. While valuation plays a role in attracting attention, long-term success is ultimately determined by financial performance.
Founder Mindset and the Need for Flexibility
A recurring theme throughout the conversation was the importance of intellectual flexibility among founders. Many founders tend to become overly attached to their initial ideas and resist feedback, which can hinder the evolution of the business.
Karthik emphasized that founders must continuously test their assumptions, remain open to constructive criticism, and adapt their strategies as needed. He also suggested that founders should approach venture capitalists for advice rather than immediately seeking funding, as this helps establish a stronger and more aligned long-term relationship.
In addition, he noted that cold outreach to large venture capital firms is often ineffective. Building relationships with smaller or micro VCs and leveraging referrals is a more practical and successful approach.

My Question: Navigating Predictability and Uncertainty in Venture Capital
At this stage, I posed a question that addressed a tension present throughout the discussion. Karthik had spoken about the ability to anticipate future trends and think in long-term horizons, yet he had also highlighted the unpredictable nature of startup journeys, including events such as co-founder exits, pandemics, and geopolitical disruptions.
The question was whether there exists a balance between predictability and unpredictability in venture capital. If investors are capable of modeling long-term risks such as wars, political shifts, and economic cycles, how do they reconcile these structured predictions with the inherent uncertainty of building and scaling startups? Does the success of an investment ultimately depend on the founder’s ability to navigate this uncertainty?
I extended this question to the domain of climate technology, considering the current geopolitical environment and the role of fund-of-funds capital, which is often linked to large oil and gas players. I asked whether investment priorities are shifting toward sectors such as supply chains, logistics, and advanced materials, where climate considerations are secondary, or whether capital continues to focus on core climate sectors such as energy, electric vehicle infrastructure, storage, and grid solutions.

His Response: Operating Without the Illusion of Certainty
Karthik responded by rejecting the idea that there is a defined balance or “sweet spot” between predictability and uncertainty. He explained that while venture capitalists do make forward-looking bets, these bets are not based on perfect foresight.
Even when trends are correctly identified, their timing is often uncertain. He mentioned that he would have preferred the electric vehicle ecosystem to mature several years earlier than it has, but its acceleration has only become evident more recently, influenced in part by broader macroeconomic and geopolitical factors.
He emphasized that both founders and venture capitalists must operate with an inherently optimistic mindset. They cannot afford to react to every external development, such as policy changes, elections, or geopolitical conflicts, by altering their fundamental approach to building or investing.
In the context of climate technology, he clarified that Blume Ventures does not position itself as an impact-focused fund. Its primary objective remains financial returns, with a target of approximately 25 percent. However, the firm is open to investing in businesses that address environmental and social challenges, provided they meet the required return thresholds.
Their investments in electric vehicles and related infrastructure, for example, were driven by the immediate need to address urban pollution in cities such as Delhi and Mumbai, rather than by abstract climate considerations.
His broader point was that while macro events can influence the pace and direction of certain sectors, they do not fundamentally change the behavior of venture capital. Investment decisions continue to be driven by conviction in founders and the ability to navigate complexity.
The Reality of Founder and Investor Relationships
Karthik also described his approach to working with founders as one of high frequency and low intensity interactions that collectively result in meaningful impact. By maintaining regular communication and being accessible for quick discussions, he is able to support founders without creating additional pressure.
This approach recognizes the emotional and operational challenges that founders face, including financial stress, team disruptions, and strategic uncertainty. Venture capitalists, in this sense, often serve as both advisors and sounding boards, sharing in the pressures of the startup journey.
Chennai’s Ecosystem and the Need for Volume
The discussion eventually shifted to the local startup ecosystem in Chennai. Karthik observed that while the city has strong institutions such as IIT Madras Research Park or the founding members of SaaSBoomi, it lacks the volume of startups required to attract consistent investor attention.
Ecosystems thrive on density, with multiple startups emerging across sectors such as artificial intelligence, healthcare, climate technology, and fintech. This concentration of activity increases the likelihood of successful outcomes and attracts greater investment.
He contrasted this with the evolution of Mumbai’s ecosystem, where entrepreneurs established the Tech Entrepreneurs Association of Mumbai to create structure and focus. Chennai, he suggested, needs a similar effort to structure and scale its ecosystem, especially for startups in the early stages.

Final Reflections
In the closing segment, several insights reinforced the overarching themes of the conversation. Karthik expressed a preference for founders with strong go-to-market capabilities, as they are often more adaptable and solution-oriented compared to those with purely domain expertise.
He cautioned against building startups based on trends, emphasizing that founders must commit to long-term value creation rather than short-term opportunities. He also addressed the challenge of balancing profitability and growth, noting that startups must optimize for not just sustainability but scale and speed if they aim to capture large markets.
Finally, he reiterated that founders should think beyond domestic markets and aim to build globally relevant businesses, as venture capital is fundamentally aligned with large-scale outcomes.
Conclusion
The conversation did not offer a simple framework or a checklist for success. Instead, it presented a more complex and nuanced view of venture capital as a discipline that operates within uncertainty.
The key takeaway was that venture capital is not about predicting the future with precision but about building conviction in the face of ambiguity. Markets will evolve, challenges will arise, and plans will change, but the ability to continue building and adapting remains the defining factor.
In the end, success in venture is not determined by the absence of uncertainty but by the ability to navigate it with clarity, resilience, and intent.
