Ando just came out of stealth with a pitch that sounds small but points at a bigger shift: workplace chat apps built for a mix of human and AI coworkers, not just humans who occasionally use AI tools.
The founder, Sara Du, is not new to building software companies. She previously ran Alloy Automation, a Y Combinator backed company that helped online stores automate their operations. That track record likely helped Ando raise 20 million dollars in pre-seed and seed funding from serious investors including Accel, Index Ventures and Emergence, before the product had even launched publicly.
The idea behind Ando came from a specific annoyance: while helping companies connect AI agents to their systems in 2025, Du kept hearing the same complaint, that someone still had to manually carry an agent's output into Slack and explain it to the team. She calls that person the "meat proxy," someone stuck translating between the AI and everyone else. Ando's fix is to give agents their own inbox and identity inside the chat app, so they can post directly, answer questions, and loop in a human when a decision needs judgment.
This is not a niche problem: Slack currently holds roughly 18 percent of the team messaging market, while Microsoft Teams controls closer to 37 percent, according to industry tracking of enterprise software use. Both companies know AI agents are becoming a bigger part of daily work, and both have already responded, with Slack rebuilding its bot into something closer to a full AI teammate and Microsoft pushing Copilot deep into Teams and the rest of Office 365. That means Ando is not walking into an empty market, it is walking into two entrenched products that are actively defending their turf.
Ando also is not the only new challenger. Jack Dorsey's Block launched a similar app called Buzz earlier this year, built on an open source AI agent framework, with the same basic pitch of putting humans and agents in the same channels. The fact that two well-funded teams landed on nearly the same idea within months of each other is a signal that this shift, agents as chat participants rather than bolted on chatbots, is becoming an obvious next step rather than a wild bet.
For a business owner, the appeal is real but the timing question matters more than the idea. Giving software agents their own identity and inbox inside your company's main communication tool also means giving them a new kind of access to sensitive conversations, client details and internal decisions. Any company considering this needs to think through who can see what an agent says, who is accountable when an agent makes a mistake in a group chat, and how that fits with existing rules on data handling, especially in regulated fields like finance, which is already one of Ando's early customer segments.
The bigger point Du is making is about headcount, not chat software. She believes small teams using agents this way can do work that used to require a much larger staff, with people focused on judgment and strategy while agents handle execution and coordination. That claim is worth watching closely over the next year, because if it holds up even partially, it says more about how teams get staffed than about which messaging app wins.
