Runable hits $21M to bet AI agents can go from building businesses to growing them

Indian startup Runable has raised $21 million to push its AI agent past website and app building and into the messier job of helping small businesses grow. The Series A was co-led by Susquehanna Venture Capital and Nexus Venture Partners, with Together Fund and Array VC also joining. After the round, co-founder and CEO Umesh Kumar said the company was valued at $65 million.

That bet is pretty specific. Runable wants to be the tool a small business owner uses to find customers, run ad campaigns, make presentations, manage social media, handle SEO, and show up in AI chatbot results. Kumar’s argument is blunt: most businesses don’t actually want a coding assistant, they want outcomes. If an agency can charge $10,000 for Google Ads, he wants Runable to do some of that work for less.

The company itself was only founded in 2025, and the pivot happened fast. Kumar and co-founder Saksham Sarda started out building browser technology for scraping data at scale, then noticed users were asking the agent to make slide decks and websites. Once payments launched in March, Runable says it went from zero to a $2 million annualized revenue run rate in three weeks.

Today the product can build websites, apps and presentations from natural-language prompts while handling some infrastructure, including deployment and analytics. The next step is the “grow” side of the business, where Runable wants to take over more of the marketing stack rather than forcing users to stitch tools together themselves. Kumar says the goal is eventually to let a small business ask for a certain number of customers, not for a website here and an ad account there.

Runable says it has about 1.7 million registered users, with the U.S., the UK and Japan among its biggest markets. Brazil is on the list too, but the company is focusing more on the first three and thinks Japan could become one of its top markets as soon as next month. Kumar declined to give current revenue or paying-customer numbers, but said users consumed more than 1 trillion tokens in the last 90 days, with about 60% to 70% of that coming from paying customers.

The economics are still ugly. Kumar said Runable has negative gross margins because it subsidizes AI usage, though it is working with a mix of models and expects inference costs to fall. The bigger problem may be competition: the same model companies powering these agents are building agents of their own. Runable’s answer is that it focuses on the whole job — infrastructure, analytics, distribution, and the marketing work in between — instead of just code.
