Working title: MausBot-style copycat for WhatsApp-first personal agents in LatAm (working name)

Summary

BriefingVerified

MausBot (founded 2026-08-11) positions itself as the open-source alternative to the big-lab personal agents (Grok Bot, Muse by Meta, Cue by Manus, OpenAI Dots): chat with a team of bots that open a browser, research, fill forms, write posts and run scheduled routines such as a morning brief.…

TrustMRR (Verified) shows $5,438 last-30-day revenue; RunsBy lists $5,434 MRR on Oct 18. Age is 73 days. The category trend is strong: Clauday's Oct 23 radar says Claude Duet, Grok Bot, Dots and Muse set off this week's discussion. Weakness: the giants are the competitors, so whitespace is local (WhatsApp, PT-BR, Pix) and price.

Description

Original: open-source team of AI bots that do real work on a computer (browser research, forms, posts, files), with routines and app connections (TrustMRR description). HBV version: a WhatsApp-first personal agent for Brazil and Mexico that handles errands (price research, form filling, bookings drafts, daily brief) with approval-by-reply; subscription with a monthly task allowance.…

Read the rest

Built on hosted agent APIs, not on custody of passwords. Global Application: personal agent for people who live in chat apps rather than desktops. LatAm Version: WhatsApp channel, PT-BR/ES, Pix billing, local errands (boleto lookups, delivery price checks).

Target customer

WhatsApp-heavy small-shop owners and professionals in Brazil and Mexico

Market and competitors

TAMHypothesisEstimate

$10B+ (Hypothesis) — Consumer AI assistant subscriptions. Method: Order-of-magnitude hypothesis. Sources: Hark estimate (Hypothesis).

SAMHypothesisEstimate

$100M (Hypothesis) — LatAm chat-app users paying for an errands agent. Method: ~20M heavy WhatsApp users x ~2% paying x ~$25/year ≈ $10M near term; $100M ceiling. Sources: Hark estimate (Hypothesis).

SOMVerifiedHypothesisEstimate

$60K ARR (Hypothesis) — 12 months. Method: ~1,000 payers x ~$60/year; about 90% of the original's current run-rate (~$65K ARR from MRR, Verified), hence ambitious. Sources: Hark estimate (Hypothesis).

Jobs to be done

When errands eat my day and I live in WhatsApp, I want an agent that does the research and drafts, asking my approval, so I can get time back safely.

HXC

Fernanda · 36 · Curitiba: Small-shop owner living in WhatsApp. Frustration & buying signal: Loses hours on price checks and forms; would pay monthly if the agent asks before acting.

Build and go-to-market

Tech stack

Cursor + Vercel + GitHub cesarx2 (one repo); Supabase; Stripe

GTM channels

PT-BR/ES SEO/GEO ('agente no WhatsApp'), recipe gallery, faceless demos; no founder face, no paid ads

Risks

Main risk

Big-lab competition, run-cost margin

All risks

Value Risk: Attention — Users may not trust agents with errands yet. Next: Start with read-only research tasks. | Usability Risk: Attention — Approval fatigue. Next: Tune thresholds by task. | Feasibility Risk: Elevated — Browser-agent infra, WhatsApp policy limits. Next: Use official Business API; prototype 3 errands. | Viability Risk: Elevated — Big labs, thin margin. Next: Price test before build.

Next validation step

Interview 15 shop owners; 3-errand prototype; price test
