Stack AI

TechCrunch reported on May 28, 2026 that Asana acquired StackAI for $75 million, with founders Toni Rosinol and Bernard Aceituno joining Asana; the deal was announced alongside Asana's earnings call as part of its push to be 'the operating system for human-agent teams' (https://techcrunch.com/2026/05/28/asana-acquires-no-code-agent-builder-stack-ai/). StackAI had raised just under $20M total (a $3M seed plus a $16M Series A from Gradient, Epakon Capital, Lobby VC, LifeX Ventures, Vercel CEO Guillermo Rauch, and others) before the sale (https://www.stack-ai.com/blog/stack-ai-raises-16m-series-a-to-create-ai-agents-for-every-job). StackAI's own post-acquisition FAQ states the product continues operating as its own brand, existing workflows and on-prem/VPC deployments are unaffected, and customer success teams stay the same (https://www.stackai.com/blog/stackai-joins-asana-to-build-the-future-of-agentic-work-management). That is a vendor commitment, not an independent guarantee — worth weighing for anyone signing a multi-year enterprise contract based on StackAI's prior independent roadmap.

StackAI is a visual, drag-and-drop builder for multi-step AI agents that read and write to enterprise systems — CRMs (Salesforce, HubSpot), databases (Postgres, MySQL), knowledge bases (SharePoint, Google Drive, Notion), and data warehouses (Snowflake) — then deploy as chat assistants, forms, Slack/Teams bots, or APIs (https://www.stackai.com/pricing, https://docs.stackai.com/). The pitch is squarely at IT and enterprise architecture teams in regulated sectors: the site's named customer case studies are healthcare (LifeMD), financial services (Middlesex Federal Savings), and nonprofit/pension administration (YMCA Retirement Fund, Diné Development Corporation) rather than general SMB automation (https://www.stackai.com/). That's a different target than Zapier or n8n, which is also how StackAI frames its own comparisons (https://www.stack-ai.com/blog/stack-ai-vs-n8n).

StackAI publishes SOC 2 Type II, HIPAA, GDPR, and ISO 27001 certifications and backs them with a real, Secureframe-hosted trust center (https://trust.stackai.com/) rather than just a marketing badge — it lists specific controls (data retention, incident response, vulnerability management, business continuity), states a May 2025 third-party penetration test concluded a 'Low' overall risk rating with no critical vulnerabilities, and offers downloadable Data Processing Addendums with both OpenAI and Anthropic directly from the site footer (https://www.stackai.com/dpa/stack_ai_open_ai_dpa.pdf, https://www.stackai.com/dpa/StackAI_Anthropic_DPA_July_12_2023.pdf). The security page also states data is AES-256 encrypted at rest and TLS 1.3 in transit, and offers four deployment models from multi-tenant cloud to air-gapped on-premise (https://www.stackai.com/security). This level of self-service documentation — real report requests, not just logos — is more than most tools in this directory publish.

The only priced tier is Free: $0/month, 500 runs/month, 2 projects, 1 seat, community Discord support (https://www.stackai.com/pricing, checked 2026-08-27). Every feature beyond that — unlimited projects, more seats, SSO, on-prem/VPC deployment, BAA signing, dedicated infrastructure, priority support — sits behind an 'Enterprise: Custom' tier with no published number at any usage level. There's no self-serve paid plan for a team that's outgrown 500 runs but isn't ready for an enterprise sales cycle. A buyer who wants a bridge between the free tier and full enterprise commitment won't find one on the pricing page.

StackAI's site carries detailed, named case studies — e.g., a virtual healthcare provider (LifeMD) reporting 475,000+ physician hours saved and 2.5M+ AI agent task executions, with a named executive quote (https://www.stackai.com/customers/how-lifemd-saves-475-000-hours-with-ai-agents) — and a 2025 blog post claiming 90,000+ signups, 100,000+ agents created, and customers including Nubank, MIT Sloan, and SmartAsset (https://www.stack-ai.com/blog/stack-ai-raises-16m-series-a-to-create-ai-agents-for-every-job). These are specific and named rather than generic, which is more credible than most vendor claims, but they remain vendor-published metrics with no independent audit trail — they should be read as StackAI's claims, not confirmed facts. Independent review sites could not be checked directly: G2 (g2.com/products/stack-ai/reviews) and Capterra both blocked automated access with CAPTCHA/403 even through a proxy. The one accessible third-party aggregator, Slashdot/SourceForge, lists a 4.5-out-of-5 rating from 53 ratings (13 direct Slashdot reviews plus 40 pulled from other verified third-party sites) as of this check (https://slashdot.org/software/p/Stack-AI/), but that source could not be cross-checked against the primary G2/Capterra listings it likely draws from.

StackAI was founded by MIT PhDs Antoni ('Toni') Rosinol and Bernardo ('Bernard') Aceituno and went through Y Combinator's Winter 2023 batch (https://techcrunch.com/2026/05/28/asana-acquires-no-code-agent-builder-stack-ai/); the company's own blog states the founders began the work in 2022, while third-party listings record 2023 as the founding year (https://www.stack-ai.com/blog/stack-ai-raises-16m-series-a-to-create-ai-agents-for-every-job, https://slashdot.org/software/p/Stack-AI/). It raised a $3M seed and a $16M Series A (2025) before the Asana acquisition closed the company's run as an independent startup in May 2026.
