The Long Middle
The year 2025 has been significant for seafund and India, and this year promises to build on the significant building blocks of a burgeoning deep tech ecosystem. Most of the real work of building deep tech happens in a phase that rarely gets written about. It is not the excitement of the first prototype, and it is not the validation that comes with scale or exits. It is the long middle.
This is the stretch where progress is uneven, conviction has to outlast clarity, and teams keep building without clear external signals confirming they are right. Over the past year, watching founders operate in this phase has shaped how we at seafund think about India’s deep tech ecosystem.
The companies that continue to move forward are not the ones chasing momentum. They are the ones learning how to stay coherent while much of the system around them remains unresolved.
India as a Training Ground for the Long Middle
India is not an easy place to build frontier technology. Infrastructure behaves differently across regions. Supply chains are fragmented. Customers expect global-grade reliability at local-market economics. Regulatory clarity often arrives late, if at all.
For years, this complexity was framed as a disadvantage, a reason serious deep tech had to be built elsewhere. That framing misses something important.
What India actually does is force founders to confront non-ideal conditions early. You do not get to assume consistency or optimize for a single variable. You learn to move forward with partial information, delayed feedback, and systems that refuse to behave cleanly.
That experience compounds. Founders who learn to build within these constraints develop sharp instincts around trade-offs between speed and rigor, ambition and feasibility, patience and urgency. These instincts translate directly into deep tech, where uncertainty is not temporary but structural.
From Ideas to Systems
One of the clearest signals from 2025 was not just that capital flowed into deep tech, but that it did so more selectively.
There were fewer deals, longer diligence cycles, and higher expectations around feasibility, manufacturability, and real-world integration. This marked a shift from idea-driven deep tech to system-driven deep tech.
Founders making progress today are not only asking whether something works in isolation. They are asking whether it can be built repeatedly, certified, deployed into messy environments, maintained over time, and sold through long procurement cycles.
That requires more than technical excellence. It requires early alignment across engineering, operations, regulation, and go-to-market, often before any one of those pieces is fully in place.
What the Long Middle Looks Like in Practice
Several of our investments reflect what deep tech building actually looks like away from hype cycles.
Calligo Technologies is tackling a fundamental bottleneck in computing. The company raised a $1.1 million pre-Series A round co-led by seafund to advance its next-generation POSIT-based semiconductor chips. Progress here is incremental by nature. This is raw computational capability, where success shows up in benchmarks, reliability, and repeatability rather than headlines.
TakeMe2Space operates in one of the longest-cycle domains imaginable. Space does not reward shortcuts. After seafund led its earlier round in 2025, the company closed a $5 million seed round led by Chiratae Ventures with our follow-on participation. Their work on AI-enabled satellites and shared in-orbit compute reflects true system-level engineering, with long feedback loops and sustained execution before outcomes are visible.
Seafund led its investment in C Electric Automotive Drives which shows what it means to own the hard part in electric mobility. The company is building a fully indigenous EV powertrain intelligence stack spanning firmware, control algorithms, and safety architecture. Their systems have already powered more than 150,000 vehicles across Indian road conditions. Scaling reliability in the real world is the work.
What these companies share is not a neat product story. It is depth of engineering, iterative refinement, and patience. Progress is measured in validated assumptions and real-world usage, not viral curves.
What Endures
Across teams like these, three traits consistently show up: the ability to manage multiple timelines without forcing alignment, the skill to translate complex technology without diluting truth, and the discipline to design for constraint rather than wish it away.
Deep tech in India will not explode overnight. It will accumulate quietly through patient teams, selective capital, and infrastructure that takes time to matter. When it surfaces, it will look sudden to outsiders and inevitable in hindsight.
Markets will change. Technologies will reset. Some theses will age poorly. What endures are founders who can keep building while the answer is still forming, and who understand that progress in deep tech often looks like ambiguity before it looks like success.
That is the work we remain committed to at seafund; staying with the hardest problems long enough for them to become meaningful

Leader Speaks
In this section, we bring you perspectives straight from seafund’s leadership. This edition, Manoj Kumar Agarwal, offers a sharp perspective on the future of Advanced Manufacturing, where India’s deeptech founders are rewriting strategy, sovereignty, and scale.
“Advanced Manufacturing is no longer tomorrow’s promise – it is today’s imperative. India is rapidly emerging as a hub for intelligent, automated, and precision-driven production. The global smart manufacturing market is expected to reach $249 billion by 2025, and India’s manufacturing sector contributes around 16–17 % of GDP, with rapid adoption of robotics, AI-enabled assembly, digital twins, and high-performance materials. Initiatives like Make in India and PLI schemes are accelerating investments, enabling high-value industrial growth and strengthening India’s global competitiveness.”
“The biggest opportunities lie where hardware, software, and analytics converge – in aerospace, EV mobility, semiconductors, industrial automation, and medical devices. Startups solving challenges in automation, precision, and quality assurance are reshaping India’s factories: predictive-maintenance robotics, smart sensors, and AI-driven optimization are already delivering measurable efficiency gains.
At seafund, we back founders who combine technical differentiation with industrial impact, helping them scale, integrate, and lead the next decade of deeptech-driven production.”
Here’s to the builders, dreamers, and disruptors – may the next quarter bring sharper ideas, bolder breakthroughs, and deeper impact.
