**The product.** A drag-and-drop builder with which a company's staff make AI agents that read and write in the systems the company already uses. It runs in the vendor's cloud, in a private cloud or on the customer's own servers. It was aimed at regulated companies such as banks and hospitals.

**Why it worked.** It aimed at regulated enterprises that needed AI agents on their own servers, with audit logs. The company said in 2025 that hundreds of organizations used it. Asana bought it in May 2026. Asana's quarterly report states the price.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

StackAI is a no-code platform: a customer builds software by dragging blocks on a canvas and writes no program. The blocks make an AI agent, a program that uses a language model to do a job such as answering IT requests or checking documents. The company said the agents work inside systems such as Salesforce, Snowflake and SharePoint. Customers can run it in a VPC (virtual private cloud, a separate network area at a cloud provider) or on their own servers.

Antoni "Tony" Rosinol and Bernard Aceituno founded it in 2022. The company said in 2024 that it launched its first product in 14 days after joining Y Combinator. The company said in 2025 that it launched the platform in April 2023. It raised a US$3 million seed round in May 2024 and a US$16 million Series A in May 2025. It then had a team of 16. Asana completed the purchase on 27 May 2026, according to Asana's quarterly report, and both founders joined Asana.

The headline figure is the price that Asana's own quarterly report gives: US$74.6 million in cash for 100% of the company. The text of that report was read as copied by Stock Titan, because sec.gov refused the download. Asana's press release did not state the price. No figure for StackAI's revenue was found.

## Why did StackAI work?

### It aimed at regulated companies that need AI on their own servers

The company wrote in 2025 that its platform can run on-premises or in a VPC. The tracker wrote that the company concentrated on financial services and healthcare. The home page says it is built for IT teams and shows audit logs and human review. The founders' letter of May 2026 names banks and hospitals among its customers.

### The founders joined Y Combinator right after their PhD defenses

The company wrote that the founders flew to San Francisco after their PhD defenses in December 2022. It wrote that they launched a first product in 14 days with help from Y Combinator mentors. It wrote that 10 customers came within weeks.

### It raised two funding rounds and had 16 people by May 2025

The company raised a US$3 million seed round in May 2024 and a US$16 million Series A in May 2025. In May 2025 it wrote that it had 16 people. It also wrote that it was hiring in engineering, customer success, sales and marketing.

### Asana's chief executive said StackAI lets customers automate complex processes end to end

Asana's chief executive said, as Pulse 2.0 quoted him, that customers already used Asana's own agents for repetitive work. He said StackAI lets them automate the most complex processes end to end. Asana paid US$74.6 million in cash, according to its own report.

## How it was built

These details come from the company's own posts and pages. They are grade C. No source describes the code.

- A canvas where a customer connects blocks into a workflow. The company's 2025 post calls it a codeless, drag-and-drop canvas builder.
- The company wrote in 2025 that it supports more than 30 model providers and more than 100 data connectors.
- The 2023 pricing page says calls to third-party model providers such as OpenAI cost extra, or the customer can use its own API keys.
- Customers can deploy on-premises or in a virtual private cloud, according to the company's 2025 post.
- After the sale, the founders wrote that the same forward deployed engineers and AI strategists keep working with customers.

## Who tried this before StackAI, and why did they fail?

Four companies in our database of failed startups promised to automate business work with AI or without code. The values below are from that database, read on 11 November 2026, and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### Olive AI (2012 to 2023; funding US$852.0M cash burned; cause: Unit economics)

- Promise: An AI workforce of software bots that would automate hospital administration.
- Why it died: Each client needed custom integrations. The bots broke when hospital systems changed. The cost to serve was far above the revenue.
- Record: 

### Ansaro (2017 to 2022; funding US$15.0M cash burned; cause: No market need)

- Promise: AI that automates the hiring process, from candidate tracking to interview scheduling.
- Why it died: Buyers saw it as nice to have. It needed change management at the customer and had no clear return on investment.
- Record: 

### Pathmind (2016 to 2019; funding US$5.0M cash burned; cause: Timing)

- Promise: AI simulations for industrial workflows, usable without deep technical skill.
- Why it died: The market was not ready. Google and Amazon had more resources. Customers needed much education and hand-holding.
- Record: 

### Crejo.Fun (2020 to 2022; funding US$3.0M cash burned; cause: Market fit)

- Promise: A no-code platform for creators in India to build their own apps and games.
- Why it died: It was a horizontal tool for a market that needed vertical solutions. The cost of acquiring users broke the unit economics.
- Record: 

## What changed

Each of the four sold automation or a no-code tool to buyers that were not ready. Olive AI promised autonomous bots and delivered custom integration work. Ansaro and Crejo.Fun asked customers to change how they work. Pathmind arrived early.

StackAI sold to IT teams in regulated companies, and the company says it supported deployment on the customer's own servers. It also gave customers dedicated engineers. The company said in 2025 that it served hundreds of organizations. Whether the margin was healthy is not known, because no revenue figure was found.

## Can one person copy StackAI now?

**Verdict: Not for one person today. The pattern of the exit is visible, but the cost is not.**

The sale followed two funding rounds, a team of 16 and enterprise security work. A solo founder cannot copy that path. The narrow audience is copyable: one buyer type with strict data rules.

1. Pick a buyer that cannot use general chat tools, such as a bank or a hospital.
2. Offer deployment on the customer's own servers or in a private cloud.
3. Start with a free plan and a priced plan, as the 2023 pricing page shows.
4. Plan for dedicated engineers at each large customer, as the company's own letter describes.

**What is still open.** Other regulated fields where AI agents must run inside the customer's own systems, such as insurance, public agencies and clinical operations.

## When did StackAI launch, and how did it grow? Timeline

From a PhD defense in December 2022 to a sale in May 2026, in 37 months from launch. Each entry carries its grade.

- **2022** (grade C [5, 6]): The company says two MIT PhD students start StackAI. They defend their PhDs in December 2022 and move to San Francisco for Y Combinator.
- **Winter 2023** (grade C [3, 6]): The tracker places the company in the Y Combinator Winter 2023 batch. The company says it launches a first product in 14 days and signs its first 10 customers within weeks.
- **April 2023** (grade C [5]): The company says it launched the StackAI platform.
- **August 2023** (grade C [10]): The archived pricing page lists a free plan, a US$199 plan, a US$899 plan and an Enterprise plan.
- **21 May 2024** (grade C [6]): A US$3 million seed round led by Gradient Ventures. The company says it has more than 40,000 users.
- **6 May 2025** (grade C [5]): A US$16 million Series A. The company says it has 16 people, 90,000 sign-ups and hundreds of organizations as customers.
- **27 May 2026** (grade A [1, 7]): Asana buys 100% of the company for US$74.6 million in cash. The founders write to customers the same day.

## What could go wrong for StackAI?

- **What is the evidence for the price.** The headline is the buyer's own filing, read as copied by Stock Titan because sec.gov refused the download. Asana's announcement gave no price. The tracker's US$75 million came from TechCrunch, which was not fetched.
- **No revenue figure was found.** The sale price is the only money figure for the business itself. No source gives revenue, profit or the number of paying customers. The price may include value for the team and the founders.
- **Part of the deal is not in the price.** Asana's report says 4.5 million restricted stock units and 3.0 million performance stock units went to StackAI employees. It says about US$20.0 million more in awards may follow. These are not part of the purchase price.
- **Trust signals on the company's pages are unsourced.** The home page shows a wall of customer logos and a count of "500+ enterprise integrations". It also shows badges for G2, SourceForge, HIPAA, GDPR, SOC 2 Type II and ISO 27001, and seven customer quotes. Some quotes name a role but no company. One says "$1M in operational savings". No source checks them.
- **Sold with engineers, not only software.** The home page lists a "White-Glove Experience" with dedicated support, and the founders' letter names forward deployed engineers. This sale concerns a software platform with a free plan. A reader can see that services were part of the offer.
