Infrasity

Infrasity is a technical content marketing and developer relations agency based in India, founded by Shantanu Das. The company specializes in marketing to developers and engineers—not traditional B2B audiences. Its primary focus is DevTool startups (CLI tools, APIs, SDKs), AI agent platforms, and observability companies, with particular strength serving Y Combinator-backed startups. The team consists of in-house engineers with 5-10+ years of experience who write and produce content hands-on.

Services and capabilities

Infrasity's core offering centers on developer marketing (B2D)—positioning products for technical decision-makers like CTOs, VPs of Engineering, and developers themselves. It produces technical blog posts (2000-4000 words), API integration guides, developer quickstart guides, product documentation, and code samples. The agency offers 7-day turnaround on technical videos and 2-3 weeks for long-form content.

Beyond written content, Infrasity handles Reddit marketing (community engagement and authentic participation in relevant subreddits) and AI GEO optimization—content optimization for AI search engines including ChatGPT, Claude, and Perplexity. This last service reflects the reality that developers now discover tools through LLM-based answers, not just traditional search.

The team develops "recipe libraries" for tech stacks like Node.js, Bun.js, React, and CockroachDB—ready-to-use boilerplate code that end users can fork and modify without starting from scratch. Content is distributed across GitHub, Stack Overflow, Dev.to, Hacker News, and technical communities.

How they work

Infrasity operates on a monthly retainer model with a 3-6 month minimum engagement. The process follows Research → Outline → Create → Distribute. In the research phase, the team identifies technical challenges and keywords that resonate with engineers. Content is crafted by in-house engineers working hands-on with client products to ensure technical accuracy. SEO optimization includes keyword research, meta tag optimization, content structure for readability, and internal/external linking.

Engagement is structured as an "extended Developer Relations Team." The agency focuses on product adoption metrics (API calls, SDK downloads, active users) rather than vanity metrics like clicks or impressions.

Notable work

Infrasity counts among its clients Firefly (cloud asset management), Terrateam, and Kubiya.ai (DevOps automation). VP of Marketing Cindy Blake at Firefly noted the team was "quick to onboard and understand how to best show off the capabilities" of their product. Co-founder Josh at Terrateam praised their "attention to detail and level of accuracy." CTO Shaked Askayo at Kubiya.ai highlighted how their "creative content has significantly enhanced the visibility and appeal of our product in a competitive market."

The company carries a 4.8 rating and is described as "one of the fastest-growing GTM & DevRel solutions companies" based in India's capital.
