Infrasity, founded by former infrastructure engineer Shantanu Das, now covers the full path a developer takes to a product: the docs they read, the threads they trust, the creators they follow and the answers AI assistants give them.
NEW DELHI, India – A developer comparing two tools today might read the docs, skim a community thread, watch a YouTube walkthrough and then ask ChatGPT which one to choose, all before speaking to anyone in sales. Infrasity, a developer marketing and technical content company based in New Delhi, has expanded its services to cover each of those stops for SaaS, DevTool and AI infrastructure companies.
The company began with technical blogs and documentation for infrastructure startups. Its work now spans technical content writing, developer marketing, community engagement, AI search visibility, GitHub marketing, technical video and B2B creator campaigns on YouTube, LinkedIn, X and Discord.
Why technical products need a different kind of marketing
Developers tend to tune out general business messaging. They want to see how a product works, whether it fits the stack they already run, and what other engineers say about it. For many technical products, that puts accurate documentation, working code examples and honest community discussion right inside the sales process.
“Most developers decide on a tool long before they fill out a form,” said Shantanu Das, founder and CEO of Infrasity. “They read the docs, they check forums, they ask an AI assistant. If a product is missing from those places, or shows up with content an engineer can see through, it loses the deal without ever knowing it was in one.”
Engineers who test the product write the content
Before starting Infrasity, Das spent years leading cloud infrastructure and platform engineering teams, with roles at ThoughtWorks and EY and as one of the people who built the platform engineering function at Experian in the UK. He has also trained thousands of engineers as an instructor on Udemy.
He built the company around a simple rule: whoever writes about a product works with it hands-on first. Infrasity’s in-house engineers set up and test each client’s product before writing the blogs, how-to guides, use case repositories, or documentation that go out under the client’s name.
What the expanded services cover
- Technical content writing and documentation: product docs, API guides, tutorials, and use case guides through its technical content writing services.
- Developer marketing: programs that follow a buyer from discovery and evaluation through onboarding and adoption, run by its developer marketing team.
- Community engagement: technically credible participation in threads where a client’s product is a fair answer to the question being asked.
- AI search visibility: content structured so that ChatGPT, Claude, Perplexity and Google AI Overviews cite a product when buyers ask for recommendations, a practice often called GEO or AEO.
- B2B creator campaigns: sourcing, vetting, negotiation, coordination and reporting for creators who cover developer tools and AI infrastructure, through its B2B influencer marketing service.
Results from recent client programs
Infrasity publishes its client results as case studies with dated screenshots from tools such as Ahrefs. A few recent ones:
- OX Security: over a 16-month program, keywords ranking in Google’s top three grew from 89 to 509, monthly organic traffic rose from 4,393 to a peak of 20,129, and the application security company was cited in 333 Google AI Overview responses across 65 pages.
- MemClaw: the AI agent memory tool grew its GitHub presence by 1,512% in six weeks.
- Brevo: the email marketing platform reached 80% LLM citation coverage across six high-intent buying prompts.
The OX Security program started with fewer pages, not more. Infrasity merged 22 competing blog URLs into eight before writing anything new, and organic traffic still doubled on a keyword footprint half its earlier size.
“Clients usually expect us to publish more,” Das said. “Often the faster win is fixing what is already there, then writing pages that a buyer and an AI model can both use. A tools comparison with clear differences between products gets cited far more often than a page that only defines a term.”
The companies Infrasity works with
Infrasity’s early clients in late 2023 included Terraform automation companies env0, Terrateam and Firefly. Y Combinator-backed DevZero and Kubiya.ai followed in 2024, and by 2025 the company had served more than 25 AI, infrastructure and security startups worldwide. Its current client roster includes Qodo, Lightrun, Daytona, Scalekit, Teleport and Brevo.
The company also builds its own tools for this work. Threadflow tracks Reddit engagement and LLM citations, and the app.Infrasity.com maps client content to the prompts buyers type into AI assistants. Free tools on its site include an AEO audit, a docs audit, and a Reddit Opportunity Finder. HackerNoon has named Infrasity the number one startup in New Delhi.
