How Momentum works

Most launch boards crown a winner at midnight and forget it by morning. The Nest ranks each launch on its launch day, then keeps tracking it every day after with a Momentum score, for as long as it's on the Nest, so you can see which products are still gaining traction weeks and months later. Here is exactly how both numbers are calculated.

Paid boosts are always labeled

Launching is free, and no badge on your site is ever required to be listed. Launch-day rank comes only from votes and follows. Makers can pay for a boost to their Momentum, and when they do, you'll always see it: the product is labeled Boosted and the boosted days are shaded on its chart.

Launch day

Each launch day runs midnight to midnight Pacific. The Today board ranks that day's launches by:

Votes from accounts less than 3 days old count as a quarter of a vote, and votes we find to be part of a vote ring or other manipulation don't count at all. Visits to a product's website don't count toward launch-day rank, because they don't need an account and are the easiest thing to fake.

Voting doesn't close at midnight. You can upvote a product any day, for as long as it's on the Nest, and each vote feeds its Momentum on the day you cast it.

Momentum, every day

Momentum doesn't end. Each night we add up what happened that day for every product that has launched:

That day's activity is the square root of the weighted total. The square root keeps a huge launch day from drowning out everything after it.

Momentum then carries forward with a 7-day half-life: each day, yesterday's Momentum shrinks by about 9.4% and today's activity is added on top.

Because every day's activity fades by half each week, a product that goes quiet drifts back toward zero by itself, and one that keeps shipping and getting noticed keeps its line up, whether it launched last week or last year. On the board, Launched this month shows products from the last 30 days, and All products shows every product that's still active. Sparklines show the last 30 days.

So a product has to keep earning attention to hold its line up. One big day fades within a couple of weeks, while steady follows, visits and shipped updates keep it climbing. Here are two made-up launches over their first three weeks, run through exactly this formula:

Both lines are drawn to their own scale, as on the board. The numbers are what compare them: the steady launch ends three weeks later with far more Momentum.

Paid boosts

A product's maker can buy a boost for 3, 7, 14 or 30 days. A boost is worth 6 points per boosted day (180 over 30 days), added to activity after the square root, so it's worth the same to every product whatever its size. For scale, on a day with no other activity, 6 points is what 36 votes adds.

The points aren't spread evenly. A boost starts strong, about 12 points on its first day, and steps down by the same amount each day to almost nothing on its last. Like all activity, those points fade with the 7-day half-life, so a boosted product's Momentum rises like an arrow: a fast climb, a peak around the middle of the boost, and a smooth glide back down, with no cliff when it ends. On a 30-day boost with no other activity, Momentum peaks around 68 on day 14.

• A boost counts toward Momentum, so it can move a product on the Momentum and Rising tabs. It never changes launch-day rank, which comes only from votes and follows.
• A boosted product is labeled Boosted on the board and on its page while the boost runs and for 14 days after, while its points fade.
• On the product's page, boosted days are shaded on the chart, and each day's breakdown shows the boost apart from votes, follows and visits, so you can always tell paid Momentum from earned.
• Only the product's own maker can buy a boost, one at a time, and only for a launch that's live.
• Occasionally we give boosts away, for example to the first launches on the Nest. A free boost works and is labeled exactly like a paid one.
• After a boost, a cooldown. Once a boost ends, the product has to rest for as long as the boost ran (7 days after a 7-day boost, and so on) before it can be boosted again. A boost is a burst: Momentum climbs while it runs, then settles back to what people are actually doing. Nobody can pay to stay on top.

The 7-day change

The ▲ / ▼ figure compares today's Momentum with the Momentum from 7 days earlier. Products with less than 8 days of history show New instead, and so do products whose score a week ago was too small for a percentage to mean anything. The Rising tab ranks products by this change.

Reading the charts

Here's how a launch looks on the Momentum board. This one is made up, drawn from the "steady attention" example above:

  Developer tools

• Hollow dot: launch day, the start of the line
• The line: Momentum each day since launch
• Filled dot: today's Momentum
• Change in Momentum over the last 7 days
• Current Momentum score, which the Momentum tab ranks by

• Each line is one product's Momentum, one point per day. Sparklines on the board are scaled to each product's own range, so they show its shape; use the Momentum score and 7-day change to compare products.
• A hollow dot marks launch day and a filled dot marks the latest day. On a product's page, diamonds mark days the maker posted an update.
• On a product's page, a shaded band behind the line marks days with a paid boost.
• A solid line means every signal was measured by the Nest itself. A dashed line means the day includes self-reported data. Today every signal is measured on the Nest, so every line is solid.

Verified traction

Makers can connect the tools they already run their business on, by signing in to them. The Nest only ever reads from them. Each night we read that day's figures and add a small, capped number of points to Momentum, so real traction counts, not just attention on the Nest.

• Verified, not self-reported. We read these figures from the maker's own accounts; the maker can't type them in.
• Missing isn't zero. A product with nothing connected isn't penalized; traction only adds.
• Revenue is only ever a range (for example $1k–10k a month), converted to US dollars, never an exact figure.
• Makers choose whether each source is shown publicly; a hidden source still counts toward Momentum. Disconnecting stops it right away.
• More sources are coming: demand (Calendly, HubSpot, Typeform, Eventbrite), audience (Mailchimp, Kit, Slack, Bluesky) and traffic (Google Search Console and Analytics).

Outside signals

The Nest also reads public signals about every product's own website, with nothing for the maker to connect. They match on the site's address, never the product's name, so a product called "Linear" can't pick up other people's mentions.

• Capped: mentions (Hacker News, Bluesky, news) at 2 a day, search (authority and keywords) at 1, outside signals together at 3, and everything from outside the Nest, connected sources included, at 6.
• Growth, not size: a big, old site doesn't outrank a new one for being big. Domain Rating is shown for context but only new referring domains count.
• A product's own pages don't count as news about it. Products on a shared platform address (like name.lovable.app) get the mention signals but not authority or search, which would describe the platform.

Links and badges

• Every approved launch links to the maker's site with a normal link, because a person reviewed it. While a product is boosted, its link is marked as sponsored, since that's paid placement.
• Badges are optional. Makers can show a badge on their own site: live Momentum, "Launched on The Nest", or an award they've earned (#1 on launch day, Top 10 Momentum). It links their visitors to their Nest page. Nothing on the Nest depends on whether a maker uses one: not their listing, rank, Momentum or link.

Product profiles and weaknesses

When a maker submits a product, Fill with AI reads the product's own website and drafts its profile: name, tagline, description, features, strengths, weaknesses, tags and category. The maker can edit all of it except the weaknesses.

• Weaknesses are locked. They're the AI's honest read of the limitations or open questions a careful buyer would want to know, based on what the site says and doesn't say (for example, "No pricing shown on the site"). The maker can't edit or delete them, and re-running the AI on the same page returns the same analysis.
• Makers can appeal. If a weakness is wrong, the maker can appeal it from the product page. A person reviews every appeal and either removes the weakness, corrects it, or keeps it.
• If a maker skips the AI, we run it when we review the launch, so every product on the board gets the same treatment.
• Strengths and weaknesses don't affect rank or Momentum. They're there to help you decide.

Keeping it fair

One account per person. Buying, trading or organizing votes, and using bots or multiple accounts, gets votes excluded and can get a launch removed. See the Nest's terms. We may improve this method over time, and when we do, this page changes with it.
