What is Prospero?

Prospero is turning proposals from documents into instrumented, reusable assets.

Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.

What is Gumloop?

Gumloop ships Gumball, background subagents, and a model router in two weeks—each one changes how agents work.

Gumloop has moved from a workflow automation platform to a multi-agent system with increasingly autonomous capabilities. In early September, the product introduced Gumball—a self-improving, proactive agent running on company infrastructure—background subagents that execute concurrently without blocking the main chat, and a Model Router that picks the right model per task automatically. These are not incremental additions; they represent a shift from 'automations you configure' to 'agents that improve themselves and manage their own execution resources.'

Prospero vs Gumloop: editorial side-by-side

Prospero is turning proposals from documents into instrumented, reusable assets.

◆ Current state

Prospero builds and sends business proposals, with templates, a content library, e-signature and CRM connections around them. The releases over the past nine months form a steady, unhurried cadence of practical additions: catalogs and saved deliverables for reusing priced line items, content locking to protect approved sections, bulk actions across proposals, form builder fields, HubSpot and Make.com integrations, and now page-by-page analytics on how prospects read a proposal.

◆ Where it's heading

Two consistent threads. The first treats proposal content as a reusable asset rather than a document — catalogs, saved deliverables, locked sections and templates all reduce how much of each proposal is written from scratch. The second instruments what happens after the proposal is sent, moving from delivery and signature toward telling a salesperson which pages held attention and which were skipped. The AI writing assistant sits alongside both without yet being connected to either.

◆ Prediction

Engagement data is now captured per page but presented for a human to read; the natural next step is acting on it — alerting when a prospect revisits pricing, or feeding the analytics back into template suggestions.

Gumloop ships Gumball, background subagents, and a model router in two weeks—each one changes how agents work.

◆ Current state

Gumloop has moved from a workflow automation platform to a multi-agent system with increasingly autonomous capabilities. In early September, the product introduced Gumball—a self-improving, proactive agent running on company infrastructure—background subagents that execute concurrently without blocking the main chat, and a Model Router that picks the right model per task automatically. These are not incremental additions; they represent a shift from 'automations you configure' to 'agents that improve themselves and manage their own execution resources.'

◆ Where it's heading

The self-improvement loop is the defining arc: Gumball learns from corrections, agents can now manage their own evaluation criteria, and the Model Router removes model selection as a user responsibility. The daily intelligence layer (Daily Chew, Gumball) is getting tighter with Highlights and actionable briefs. Gumloop is building toward autonomous contributors—proactive, self-assessing, and model-aware—rather than user-triggered task runners.

◆ Prediction

The next move is likely deeper agent-to-agent orchestration—routing work between Gumball and specialized subagents based on task type—or expanding the self-improvement loop to cover skill acquisition from past successful runs.
