Vertical AI Assistant Marketplace (Specialized Lindies)

A marketplace of pre-configured, role-specific AI assistants — social media manager, sales rep, front-end engineer — each available as a dedicated iMessage phone number ready to use instantly.

01 THE IDEA

Greg pitches this idea mid-conversation as a natural extension of the iMessage AI assistant concept: instead of one general executive assistant, offer a catalog of specialized AI workers — a social media manager Lindy, a salesperson Lindy, a front-end engineer Lindy — each pre-configured with the workflows, integrations, and persona appropriate to that role. Users would simply 'download' (subscribe to) the one they need, get a phone number, and immediately have a specialist available over iMessage.

This is essentially a marketplace model where each 'agent' is a vertical SaaS product with deeply opinionated defaults for a specific job function. The business model could be a platform fee plus per-agent subscription, or a marketplace where third-party developers build and sell specialized agents. The founder of Lindy confirmed this is directionally the five-year roadmap, validating the demand signal. A standalone builder could target this niche today by productizing one or two high-demand roles (social media manager, SDR/sales assistant) before horizontal players catch up.

03 THE VERDICT

The idea is directionally compelling and the demand signal is strong, but the competitive dynamics are tricky — Lindy itself is planning to build this, and well-capitalized horizontal platforms will eventually commoditize role-specific agents. The opportunity is real for a first-mover who picks a specific vertical and builds an agent so good that switching costs become meaningful. However, the platform/marketplace version of this idea is likely too capital-intensive for a solo founder to compete with Lindy or Salesforce at scale. Best path: build a single hyper-specialized agent (e.g., AI SDR for SaaS companies over iMessage) rather than a full marketplace.

Verdict: MAYBE — read why above. Still convinced? A vetted builder can pressure-test the scope before you commit.
