EchoSift

Build SaaS that actually sells

EchoSift shows you validated developer demand, before you write a line of code. It watches GitHub issues, Stack Overflow questions, Hacker News threads and Bluesky posts, clusters recurring complaints into scored pain signals, and tells you which ones are worth building. Every signal is counted by how many distinct teams hit it, not by upvotes or vibes.

For your agent

Your agent builds what sells. Connect your coding agent to the EchoSift MCP server and it pulls real developer demand so you ship the winners. Works with Claude Code, Cursor, Codex and any MCP client.

Add the server with claude mcp add --transport http echosift https://mcp.echosift.io/mcp then sign in once via OAuth. Eight read-only tools, 60 requests per minute, Pro plan required for tool calls. Full setup in the documentation.

How it works

Scan the board. Every developer pain, scored by how many teams hit it, ranked by what is moving.
Open a signal. Click through to the evidence: the rising curve and the real complaints behind it, with their sources.
Generate the brief. One click turns a signal into a brief: the incumbents, their gaps, the wedge, and a build or skip verdict.
Follow it. Follow a single signal or a whole area. Your watchlist tracks them as they move, with a weekly digest and threshold alerts.

From a terminal, your agent runs the same loop: wake up already briefed on what is moving, take an idea to a verdict in seconds, let the market rank your roadmap, and scaffold from the brief to a repo in one session.

Why not just ask an LLM?

Live, not from memory. A model stops at its training cutoff. EchoSift reads new complaints every day.
Receipts, not vibes. Every signal links to the real posts, with permalinks. Read them before you build.
Counted, not guessed. We score each pain by how many teams hit it. Loud never beats real demand.

The cost of guessing

An estimated $1.7M of validated demand is sitting in EchoSift right now: money on the table for anyone who builds with EchoSift as their market analyst and advisor. Estimated across our top 73 multi-owner signals, valued conservatively.

Pricing

One plan. Agent included. $39 per month or $390 per year. Everything in the dashboard, and your coding agent can use it too. Pro includes the full signal board with evidence and timelines, AI opportunity briefs with build-or-skip verdicts, MCP server access (8 tools, 60 requests per minute), follows with a weekly digest and threshold alerts, and all sources refreshed continuously. There is no free trial because the signal data is the product; cancel anytime from the billing portal. See pricing.

Questions, answered plainly

Where does EchoSift find pain signals?: GitHub issues, Stack Overflow, Hacker News and Bluesky, ingested through our own pipeline using sanctioned APIs. New content is processed within minutes, so you see momentum building before it hits any front page.
Why a subscription and not a one-off?: Because markets move. New complaints land daily, signals rise and fade weekly, and the point is catching them early. You follow what you care about and EchoSift keeps watching: digests, alerts and fresh clusters in your areas.
What exactly does my agent get over MCP?: Eight read-only tools: taxonomy, semantic search, signal listings, trending, signal detail, timelines, evidence with real quotes, and opportunity briefs. Your agent authenticates once via OAuth and works at 60 requests per minute. Nothing is written to your account unless you do it yourself in the dashboard.
How does the scoring work?: Each signal gets a composite score from volume, week-over-week growth, recency and cluster diversity. Diversity matters most: a pain spread across dozens of independently-owned projects is a market signal, while a pain confined to one repository is usually a vendor backlog.
What does an opportunity brief look like?: It names the incumbents already in the space, lists their concrete gaps such as pricing plans, missing SDKs or deployment options, and gives an honest verdict: worth building, needs a wedge, or saturated.
Is there a free trial?: No. The signal data is the product, so we cannot give it away without giving away the value. You can cancel in two clicks from the Stripe portal in your first week if it is not for you.
How do you handle privacy?: Author handles are pseudonymized with HMAC-SHA256 at ingestion. We never store real usernames or personal data, and GDPR Article 17 erasure is supported across the whole pipeline. We track market pain, not individual people.
What if a source changes its API rules?: The pipeline was built on multiple diversified sources from day one. If one platform tightens its terms, the others keep delivering.
