TL;DR: StackAI, a startup that allows businesses to build AI agents without code, has raised $16 million in Series A funding. With backing from Gradient Ventures and angel investors from OpenAI and DeepMind, the company aims to bring generative AI automation into the hands of non-technical users.
Making AI Agents as Easy as Spreadsheets
In the ever-accelerating world of generative AI, StackAI stands out for one core promise: letting anyone build powerful AI agents without writing a single line of code.
Founded in 2022 by MIT PhDs Antoni Rosinol and Bernard Aceituno, the San Francisco-based startup has now raised $16 million in Series A funding led by Lobby VC and LifeX Ventures, with participation from Gradient Ventures (Google’s AI-focused fund), First Round Capital, Soma Capital, Y Combinator, and angel investors including leaders from OpenAI, DeepMind, Notion, and Replit.
Co-founder and CEO Arun Kirubarajan says the mission is simple: “We want to make AI agents usable by anyone, not just machine learning engineers.”
Why This Matters
While tools like ChatGPT and Midjourney have made AI more accessible, creating custom AI workflows or autonomous agents still often requires engineering skills. StackAI removes this friction by offering a drag-and-drop interface that connects AI models (like GPT-4), external APIs, and conditional logic blocks into end-to-end workflows.
Think of it like Zapier, but built for the AI-first era.
Users can build agents to automate tasks like:
- Drafting personalized sales emails
- Summarizing support tickets
- Enriching CRM records with public data
- Creating onboarding chatbots
The platform is already being used by teams at Ramp, Notion, and Zapier to automate repetitive tasks.
The Surge in No-Code AI
StackAI isn’t alone in this space. Startups like Cognosys and Dust are also exploring ways to build agentic workflows without requiring Python. But StackAI has leaned into simplicity and enterprise use cases.
“This is the AI equivalent of what Airtable and Notion did for databases and docs,” said one investor familiar with the deal.
The product also plugs into popular tools like Slack, Notion, HubSpot, and internal CRMs-lowering the integration barrier for busy business teams.
Who Backed the Round
In addition to Gradient Ventures, the round included participation from:
- Lobby VC
- LifeX Ventures
- First Round Capital
- Soma Capital
- Y Combinator (StackAI is an S22 alum)
- Angels from OpenAI, DeepMind, Notion, and Replit
- Guillermo Rauch (CEO of Vercel)
- Bob van Luijt (CEO of Weaviate)
This brings StackAI’s total funding to just under $20M.
What’s Next for StackAI
The funding will be used to scale their engineering team, build out integrations, and improve the platform’s ability to reason across complex workflows.
They’re also launching a self-service onboarding experience this quarter, allowing individual professionals to spin up agents without sales calls or demos.
“The future of work is autonomous, collaborative, and AI-powered,” says Kirubarajan. “We’re building the toolkit to enable that.”
Takeaway: Why You Should Pay Attention
While enterprise AI tools are booming, there’s still a gap between model innovation and end-user utility. StackAI’s no-code approach brings the power of AI agents to operations, marketing, and product teams without needing an engineering sprint.
If you’re watching the evolution of generative AI from hype to hands-on tools, StackAI might just be one of the startups turning that promise into reality-one drag-and-drop block at a time.
