Peak XV Raises Surge Seed Investment Limit to $5M, Reveals 18-Startup Cohort

Peak XV Lifts Surge Seed Investment Cap to $5 Million, Backs 18 New Startups

Peak XV Partners has raised the maximum investment ceiling for its Surge seed-stage programme to $5 million, up from the previous $3 million cap. The venture capital firm unveiled the change alongside the twelfth cohort of Surge, which comprises 18 startups spanning artificial intelligence, robotics, space technology, healthcare, financial services, and music .

A Revamped Surge

Under the revised structure, Surge can now invest between $500,000 and $5 million per company, compared with the earlier range of up to $3 million . The decision to increase the ceiling brings Surge closer to Peak XV's broader early-stage investment practice, as the firm responds to a market where capital-intensive deep tech companies are raising larger rounds at the seed stage .

Rajan Anandan, Managing Director at Peak XV and Surge, said the founders in the new cohort are "building from first principles" as AI increasingly becomes "the architecture of the product rather than the product itself" .

Global Ambitions and Indian Roots

Of the 18 companies in the cohort, 13 are targeting global markets, while more than half are headquartered in India . Peak XV did not disclose the individual investment amounts, but the firm invested more than $50 million across the group, which collectively has raised over $90 million in seed funding .

The Cohort: AI, Robotics, and Beyond

The new batch reflects three broad shifts in early-stage technology: consumer experiences being rebuilt around new expectations, AI moving from a feature to underlying infrastructure, and technology increasingly tackling physical-world problems .

AI-native companies make up roughly half the cohort. Alma, founded by former Microsoft Research engineers who later became founding engineers at Sarvam AI, is working on personal computing for an AI-native world . Reinforce Labs is developing evaluation and red-teaming tools for enterprise AI systems, while hiloop is building infrastructure for post-training open-weight AI models .

Deep tech and infrastructure ventures include Puralink, which is developing autonomous robots to inspect underground pipe networks, and ULOOK, which is building satellites for radio-frequency sensing and spectrum intelligence .

Consumer and healthcare startups include August AI, which combines AI tools with physician-led primary care and claims nine million users across 160 countries, and Hoola Health, a paediatric care platform . Ditto is building an AI dating matchmaker inside iMessage, while Riffle is developing a browser-based platform for music creation and collaboration .

Three companies in the cohort — spanning education, applied AI, and medical products — remain in stealth mode .

Experienced Founders

The cohort includes several repeat founders and operators. Mona Gandhi, co-founder of Kello, was Airbnb's first female engineer and previously founded Upraised. Anish Das Sarma, founder of Reinforce Labs, holds a Stanford PhD, built a company acquired by Airbnb, and later led AI teams at Google . Alma's founders previously worked together at Microsoft Research before joining Sarvam AI .

Since its launch in 2019, Surge has backed more than 180 startups across 18-plus nationalities, with its top 10 portfolio companies generating over $1 billion in combined annual revenue .
