Two years ago my team of four kept losing track of who was doing what, so I built Plumline. Version 2 ships today. Here's what we got wrong the first time.

Done: four posts, one per network, each inside its character limit and scheduled for Thursday at 9:00 AM Pacific. The LinkedIn one puts the link in the first comment.

The company and the founder, each in their own voice

Early on, the founder is half your reach. Give the company and each founder a brand workspace with its own profiles, tone and time zone, and AI writes for each one the way they sound.

2 brands on Sprout, 5 on Bloom, 15 on Thrive.
Personal LinkedIn and the Page. Both publish; reports cover LinkedIn Pages.
Approvals when you grow. From Thrive, posts can wait for a cofounder's yes.

From people who automate everything

Connecting accounts was fast, the interface is one of the cleanest I've used… If you're interested in AI workflows, the MCP integration also opens up some exciting possibilities.

Their powerful API and n8n integration let me automate months of video and post scheduling in advance…

Between the AI content generation and the bulk scheduling, I've shaved hours off my weekly workflow.

Startup social media, answered

What is the best social media management tool for a startup?

One that keeps up with how fast you ship: launch on every network at once with copy tuned for each, turn changelog entries into posts automatically, let your own systems and AI post through an API, and show traction without a spreadsheet. RobinReach does that across 13 networks, starts free, and charges flat monthly prices instead of per seat.

How much does RobinReach cost for a startup?

Seed is free for 2 profiles. Sprout is $9 a month for 5 profiles and 2 brands, enough for the company and a founder. Bloom is $24 for 15 profiles, 5 people, X, reports, the API and Claude or ChatGPT. Thrive adds approvals and 15 people.

Can we launch on every network at the same minute?

Yes. Schedule one post to every profile for the same time in your brand's time zone, with different copy for any network that needs it. PostWave (from Sprout) turns your launch blog post into a set of draft posts to start from.

Does RobinReach post to X, and are there limits?

Yes, from Bloom, threads included. Because X charges for its API, each plan has a cap: 1 X account and 5 posts a day per account on Bloom, 3 accounts and 12 a day on Thrive, 10 and 15 on Scale.

Can our changelog post itself?

Yes. Add your changelog or blog as an RSS feed (from Sprout) and RobinReach checks it every 3 to 12 hours, turning each new entry into a draft, a scheduled post or a post that goes out right away, with its image and link.

Is there an API?

Yes, from Bloom: a REST API for creating and scheduling posts, an n8n community node, and an MCP server so Claude, ChatGPT or Codex can plan and schedule posts for you.

Can we run the company account and the founders' accounts together?

Yes. Give each its own brand workspace with its own profiles, tone and time zone. Sprout includes 2 brands, Bloom 5 and Thrive 15. Personal LinkedIn profiles can publish; analytics cover LinkedIn Pages.

Can we show traction to investors?

From Bloom, reports cover eleven networks: followers over time, engagement, reach and top posts, compared with the period before. Schedule a monthly PDF to your cofounders or investors, sent at the hour you choose.

What doesn't RobinReach do for startups?

It doesn't post to Product Hunt, Hacker News or Reddit, run paid ads or do social listening. Analytics for personal LinkedIn profiles aren't available, only for Pages, and X post numbers are on Scale. Better you know before launch day.
