For marketers · Agentic marketing

# Knows your company.

Knows your rivals.

Keeps you in the loop.

One Monday email. A brief on what your competitors actually did, written in your voice with your positioning — so you can act, not just read.

3 agents standing by

## 3 rivals. One Monday email. Free forever.

The agents are usually faster than your inbox refresh.

Where the agents read

## Six sources, one brief.

Discussions mentioning your rivals, scored by upvotes.

### Hacker News

Threads and Show HN launches, weighted by engagement.

### Web news

Press, layoffs, fundings, exec moves via Bing + Google News.

### Their websites

Diffs on pricing, features, hero copy, About pages.

### Their blogs

Every new post, with topic tag + 1-line summary.

### Their changelogs

Releases parsed into per-feature entries with category.

More sources land in [the changelog](/changelog) as agents learn to read them — careers pages, podcasts, app store reviews next.

How it works

## Three agents. One brief.

End to end, no humans in the loop.

01

### The context agent

Reads your own homepage, pricing, features, blog. Drafts five markdown docs about you — positioning, ICP, pricing, voice, differentiators. Refreshes weekly. Editable in your dashboard.

02

### The signal agent

Watches your rivals every Monday: snapshot diffs, changelog entries, blog posts, Reddit, Hacker News, web news. Each signal scored, deduped, filtered for actual relevance.

03

### The editor agent

Combines your context with the week's signals. Writes a tailored brief — patterns across rivals, side-by-side contrasts vs your positioning, and ≤30-word drafts you can ship that day.

## What an agentic brief looks like.

Week of 26 May 2026

### Webflow pivots to agentic web. Notion opens agents to devs. Your pricing model wins.

Three tracked rivals are doubling down on AI agents this week. For your business, the pattern is clear: agent-native workflows will demand exactly the infrastructure you already sell. Your transparent pricing and global CDN are no longer differentiators — they're table stakes. The real win is positioning yourself as the image layer agents expect.

You vs them

YOU

Spronta positions as a modern, developer-first image CDN with flat-rate pricing and zero configuration.

| Webflow | Pivoting to agentic design. Their agents will demand fast, predictable image transforms — your model is their baseline expectation. |
| Notion | External Agents API + multi-region infra. No native image layer — exactly your wedge. |
| HubSpot | Partner ecosystem hardening. Developer-first positioning opens door to agent-native integrations. |

WHAT YOU SHOULD DO

Rewrite your pricing hero to lead with "No credits. No transformation units. No egress fees." Pair with a direct comparison vs. legacy image CDNs.

PRICING COPY — READY TO SHIP

Webflow simplified plans. Spronta simplified pricing. Flat rates. No math required.

Real digest output. Yours will be specific to the rivals you add and the context docs about your business.

### Rival Snapshot — $29

One competitor. One inbox-ready brief. No subscription, no card-on-file.

Why we're building this

Most newsletters are written once and broadcast to thousands. They optimise for the average reader. That's the wrong shape for marketing intelligence — what helps one team is noise to another.

We're testing the opposite: a newsletter where AI agents draft *a different brief for every subscriber*, every week, anchored to context docs they keep current about each subscriber's own positioning.

We're building hyperpersonalised content at scale.

How we work

## No fluff. No spam. No selling your email.

### One email a week

Mondays at 9am UTC. Daily alerts are opt-in only.

### Unsubscribe in one click

No retention dark patterns. The link's in every email.

### Your tracked list is private

We don't share what you watch with anyone.

### Public sources only

No LinkedIn scraping. No logged-in extraction.
