**The product.** A team messaging app with channels, group chats, threads and calls, plus a memory that records who said what and what happened afterward. People and AI agents such as Claude Code can ask the memory what the team decided, so nobody has to explain it again. It imports Slack history and also works as an assistant inside WhatsApp, Telegram and text messages.

**Why it worked.** The company says a team with several AI sessions running at once loses track of what each session learned. Its answer is a chat app whose memory is shared between people and agents. The company's FAQ lists a price of US$23 per user per month for commercial use. No source shows that this drew paying customers.

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

Praxos is team messaging with a memory. The memory is a store built from chats, call transcripts and AI coding sessions, and a person or an agent can ask it what happened. An agent here is an AI program, such as Claude Code, that works on a task for a user. The company says a new hire or an agent can catch up by asking.

Lucas Urbisaia (chief executive) and Soheil Sadabadi (chief technology officer) are named as founders on the Y Combinator company page. The page says the company was founded in 2023, joined the Summer 2024 batch and has 3 people. The newspaper La Nación dates the start to November 2023. The first product, from March 2024, automated paperwork for insurance brokers, not team messaging.

This story has grade E: no revenue figure was found. The company's FAQ lists US$23 per user per month for commercial use and free personal use, and the terms of service describe payment of "Charges". No source states that a customer has paid.

## Why did Praxos work?

### The memory is fed by chats, calls and agent sessions

The home page says Praxos learns from chats, saved call transcripts, coding-agent sessions and connected apps such as Slack and Discord. A person or an agent then asks what a teammate did or decided. The page gives no result from real customers.

### Slack history imports in one click to lower the cost of switching

The company says Slack history and automations come over in one click, and Slack Connect channels are mirrored. Its FAQ calls Slack, WhatsApp and Telegram bridges for teammates who refuse to leave.

### One price covers commercial use while personal use stays free

The FAQ sets one price for commercial use and makes personal and family use free. A free personal tier lets a founder try it alone, and the company says it gets better with each teammate.

## How it was built

These details come from the company's privacy policy, security page and home page. They are grade C.

- The privacy policy names Google Gemini for replies, voice, images and documents, and for building each user's memory.
- It also names Microsoft Azure AI for replies and Amazon Bedrock for building and searching memory.
- The security page says data is encrypted at rest with AES-256 in Microsoft Azure data centers, in the United States by default.
- The home page says users connect Claude Code or Codex to Praxos, and the FAQ describes an install command for the terminal.
- Apps for Mac and Windows, a web app, and links to WhatsApp, Telegram, iMessage and SMS appear on the company's pages.

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

Three companies in our database of failed startups tried to improve how teams communicate and share knowledge, and closed. The values below are from that database 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.

### Memo (2020 to 2023; funding US$5.0M cash burned; cause: Competition)

- Promise: A place to create and archive rich media memos, so that engineering, product and design teams could replace scattered communication channels.
- Why it died: The page says it could not compete with entrenched incumbents that added similar features, and that team-wide adoption was hard to reach.
- Record: 

### Team Apart (2008 to 2011; funding US$2.0M cash burned; cause: No Market Need)

- Promise: Video calls, screen sharing and collaboration tools in one web page for distributed teams.
- Why it died: The page says it struggled with product-market fit in the late 2000s, and that server and bandwidth costs for video were high.
- Record: 

### Unflow (2019 to 2022; funding US$1.2M cash burned; cause: Competition)

- Promise: One place for designers, engineers and product managers to work together on a digital product.
- Why it died: The page says it could not stand apart in a crowded collaboration market, and its unit economics struggled.
- Record: 

## What changed

Each of the three sold a shared place for a team to talk or work, and the pages say larger suites added the same features. Praxos also sells a team chat, so it meets the same competitors. The home page says Praxos is built to replace Slack.

The company says the difference is the memory that agents can read. The pages cannot show whether that is enough, because no source reports customers or revenue.

## Can one person copy Praxos now?

**Verdict: Not shown yet.**

No source shows that this business earns money, so a reader cannot yet copy a result. The structure on offer is a free personal tier with a per-user price for business use.

1. Give individuals a free tier so that one person can use the product before a team joins.
2. Charge per user for commercial use, and say which connected tools count as commercial.
3. Offer a one-click import from the tool you want to replace, so switching costs little.

**What is still open.** Any shared workspace where people and AI agents both need the same history, such as support, sales or operations.

## How much revenue does Praxos make? The numbers, graded

No revenue figure is public. The facts show a November 2023 start, an earlier insurance product, a published price and a small team

| Fact | Value | Grade | Note | Sources |
|---|---|---|---|---|
| Company named in the terms | Praxos Intelligence, Inc. | C | Terms of service, last revised 21 February 2026: a legal agreement "BETWEEN PRAXOS INTELLIGENCE, INC." and the user. The home page footer gives the same name. | [3, 1] |
| Founders | Lucas Urbisaia and Soheil Sadabadi | C | Y Combinator company page: Urbisaia as "Founder/CEO" and Sadabadi as "Founder/CTO". Tracxn also says the company was founded by the two. | [5, 6] |
| Start of the company | November 2023 | C | La Nación, 25 October 2024: "Así surgió, en noviembre de 2023, Praxos" (translation: this is how Praxos began, in November 2023). Y Combinator page: "Founded: 2023". Tracxn says "founded in 2023". | [14, 5, 6] |
| Earlier product | AI workflow automation for insurance brokers | C | The earliest archived copy of praxos.ai, 27 February 2024, is titled "Praxos \| AI for Insurance". A copy of 26 April 2024 adds a pricing link and "Start Free Trial". The founder told La Nación that no product was on the market before the last week of March 2024. | [7, 8, 14] |
| Personal assistant and the older web address | named in the privacy policy | C | The policy, revised 11 October 2026, covers www.mypraxos.com and "our artificial intelligence-powered personal assistant". The archive copy of mypraxos.com of 13 July 2025 is a domain-parking page. | [4, 11] |
| Team size | 3 on the Y Combinator page; 4 employees on Tracxn | D | Y Combinator page: "Team Size: 3", undated. Tracxn: "4 as on Sep 30, 2026". The home page demo shows "14 members", which is sample data. | [5, 6, 1] |
| Funding | Summer 2024 Y Combinator batch; seed round | D | La Nación reported on 25 October 2024 that Praxos had recently received US$500,000 from Y Combinator. Tracxn says Praxos "has raised a total funding of $500K over 1 round". No Praxos page states an amount. | [5, 6, 14] |
| Price of commercial use | US$23 per user per month | C | FAQ on the home page: "For commercial use ... it costs $23 per user per month." Personal and family use is free. | [1] |
| Payment path | Charges in the terms; Stripe named | C | Terms, section 22: Praxos "will process payment of the applicable Charges" and send a receipt. The privacy policy links to Stripe's cookie page for its "Payment Services Provider". | [3, 4] |
| Team messaging launch post | 21 August 2026 | C | The page data of the Y Combinator launch post gives that creation date. It says the product "already works and is in use" and offers 6 free months to the first 10 teams. | [5] |
| AI and cloud providers | Google Gemini, Microsoft Azure AI, Amazon Bedrock | C | Privacy policy: Gemini writes replies and builds memory, Azure AI processes content, and Bedrock builds and searches memory. The security page names Azure data centers. | [4, 12] |
| Customers named on the pages read | none | C | No logo wall, customer quotation or customer name appears on the home page, FAQ or skills page. The names in the demo are sample data. | [1, 2, 10] |

How to read this table. Grade C is a statement by the company or a page it runs. Grade D is a third-party estimate or a single report. A grade E story has no dated money figure, so no row here is a revenue number.

## Pricing

Praxos price as the company's FAQ states it, read on 12 November 2026 (grade C)

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Personal and family use | 0 | 0 | free; no commercial use |
| Commercial use |  | 23 | per user; work with business information and connected tools such as GitHub, Claude Code, Linear and Airtable |

The page names no plan. It says personal and family use is free, and commercial use costs US$23 per user per month. It does not say whether that price is billed yearly or monthly. The company's separate pricing page was not found: the address returned an error.

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

From the November 2023 start and an insurance product to a team messaging launch in August 2026. Each entry carries its grade.

- **November 2023** (grade C [14, 5, 6]): The company starts, as La Nación reports. Y Combinator and Tracxn give the year 2023. The founders build software for insurance brokers.
- **27 February and 26 April 2024** (grade C [7, 8, 14]): Archived copies of praxos.ai sell AI automation to insurance brokers. The April copy adds a pricing link, a free trial and a login. The founder dates the market launch to the last week of March 2024.
- **2024** (grade D [5, 6, 14]): The company joins the Y Combinator Summer 2024 batch. La Nación reports US$500,000 from Y Combinator, and Tracxn lists a US$500K seed round.
- **21 August 2026** (grade C [5]): Urbisaia posts the team messaging launch on the Y Combinator page and invites teams of 2 to 10 people to be onboarded.
- **11 October 2026** (grade C [4]): The privacy policy is revised. It names the AI providers, shared spaces and a personal assistant.
- **12 November 2026** (grade C [1]): The FAQ lists US$23 per user per month for commercial use and says personal use is free.

## What could go wrong for Praxos?

- **What is not verified.** No revenue figure was found. Pages read: the home page, FAQ, terms, privacy, security and skills pages, a Y Combinator page, Tracxn and archived copies. A price and payment terms exist, but no source states that a customer has paid for team messaging. No checkout page could be read without an account. In October 2024 the founder told La Nación that the insurance product gained customers almost every day. La Nación also reported that the founders projected revenue above US$1 million for 2025; no later source confirms it. The US$500,000 of funding is the figure of La Nación and Tracxn. A reader could look for a customer statement.
- **Earlier product and company start.** The company's pages from February and April 2024 sell AI for insurance brokers. La Nación dates the start to November 2023, and Y Combinator and Tracxn both give 2023. The privacy policy later describes a personal assistant, and the July 2025 archive copy of mypraxos.com is a parking page. No page dates the move to team messaging; the launch post is dated 21 August 2026.
- **Demo content, no logo wall and no testimonials.** The home page shows a demo with sample names, a company called Acme and "14 members". These are sample data, not customers. No logo wall, customer quotation or user counter appears on the pages read, so a reader cannot check who uses the product.
- **Messaging and email access.** The company's pages describe an assistant that reads, searches and drafts a user's email and sends invites at the user's request. No page offers bulk outreach. The privacy policy says the service may let users "automatically post updates on certain social media platform such as Twitter/X, LinkedIn, or Discord". No product page read offers such posting. The skills page also lists small routines such as medication reminders and a daily stocks brief. The terms ban spam.
