Ada
Ada builds AI agents that handle customer service chats for large companies.
Ada is growing fast and holding enterprise accounts, but it hasn't raised money since 2021 while Sierra and Decagon raise billions to chase the same customers.
Ada makes software that uses AI to handle customer service questions and tickets for companies. The company has real customers (550+), makes real money ($70M a year), and keeps those customers loyal through data they store in Ada's system, integrations into their other tools, and compliance requirements. But Zendesk, Salesforce, and Intercom are all bigger and richer, and they have already built similar AI features into their own products. Since these giants already own the main customer service system most companies use, they can offer everything in one place and don't have to adopt Ada separately. Ada also hasn't raised funding since 2021, while competitors like Sierra and Decagon have billions to spend on development and sales. The one thing that could change everything is whether Ada can raise a new round of funding at a strong price soon. If it can't, or if the price is disappointing, Ada may not have enough money to compete with the bigger players in a market that demands constant investment.
Ada's valuation lands flat or down versus Sierra's $15.8B or Decagon's $4.5B raises. Would indicate Ada is falling behind better-funded rivals in investor confidence.
Zendesk, Salesforce, or Intercom announce further AI-agent acquisitions or bundling moves. Would show incumbents absorbing Ada's category into existing suites.
- $70.6M estimated ARR
- 146% net revenue retention claimed
- Last priced at $1.2B in 2021
- No new funding round since May 2021 Series C while AI-native rivals raise at multi-billion dollar valuations.
- Incumbent suites Zendesk, Salesforce and Intercom bundling agentic AI natively into products enterprises already own.

- Growth and retention figures (146% NRR, 100%+ YoY growth) are company-sourced and not independently audited.
- Gartner prediction that companies cutting CX staff for AI may rehire by 2027 could challenge ROI narratives vendors like Ada promote.

- Is Ada profitable in 2026?
- Ada has not disclosed profitability figures. It claims over 100% year over year revenue growth and 146% net revenue retention for its most recent fiscal year as of March 3, 2026, but no public profit or loss data exists since it remains a private, venture backed company.
- Who is Ada's biggest competitor?
- Ada faces pressure from AI native rivals Sierra, valued near $15.8B after a $950M raise in May 2026, and Decagon at roughly $4.5B, plus incumbent suites Zendesk, which acquired Forethought in March 2026, Salesforce Agentforce, and Intercom's Fin priced at $0.99 per resolution.
- Could AI replace Ada's own workforce?
- Ada's headcount has grown, not shrunk, reaching about 768 employees by June 2026 per Crustdata, up from 400 in January 2024. Unlike Salesforce or GitLab, no layoffs tied to AI have been reported at Ada as of mid-2026.
- Who owns Ada, is it publicly traded?
- Ada is privately held and not listed on any exchange as of mid-2026. Its last disclosed priced round was a $130M Series C in May 2021 led by Spark Capital, valuing it at $1.2B, with no confirmed acquisition or ownership change since.
- How much funding has Ada raised?
- Ada's last disclosed priced round was $130M in Series C funding in May 2021 at a $1.2B valuation, led by Spark Capital with Tiger Global, Bessemer, Accel, FirstMark and Burst Capital participating. It also received a CA$1.75M non-dilutive grant from FedDev Ontario in March 2025.
- Will Ada raise a new funding round soon?
- As of mid-2026, Ada has not announced a Series D or new valuation since its 2021 $1.2B Series C, despite claiming over 100% revenue growth in its most recent fiscal year as of March 2026. Rivals Sierra ($15.8B) and Decagon ($4.5B) have both raised at far higher valuations recently.
