How Adam's MoltSets, With a $27/mo Unlimited Plan, Is Changing the Industry

Opinion. This is my read of public pricing pages, the founder's own newsletter and our own tests.

I think a $27 a month contact data API has started to move what B2B data costs. Not everywhere, and not by much yet. One vendor cut its entry price. One raised it. Three held, and four could not be checked. The window I'm reading runs from 4 August 2026, the earliest public capture of MoltSets' $27 plan, to 27 October 2026, when I last read every page cited here: 84 days, or twelve weeks. And every vendor price below is the vendor's own, as of October 2026.

My take

I think a $27 flat-rate API has started to reset what buyers expect contact data to cost. Within eight to ten weeks of MoltSets listing that price, BlitzAPI put a $99 entry plan where its $399 plan used to sit, and I read that as another vendor moving in its wake. It's one move by one vendor so far. The evidence under that read is thinner than my title.

What $27 buys

The founder's 9 October launch post sums the offer up in one line: "$27/mo unlimited, API only, NO UI/UX". A few paragraphs earlier, in the same post, he takes the obvious objection head on. And his answer is that the plans are priced by rate limit.

On the $27 Solo plan you get 1,000 enrichment records every 5 hours, 5,000 a week on a rolling window, and 3 searches running at once, per MoltSets' rate limit page on 27 October. Go over and a single call is refused with a 429 error and a wait time (the page's own example is 7,200 seconds). A batch that runs past the window returns 200 with the items beyond your allowance dropped and an error block naming the cap. The docs list no overage charge.

Run that cap through a month and the price looks different. Five thousand records a week is about 21,667 a month (5,000 times 52, divided by 12), which puts the $27 plan at about $1.25 per 1,000 records if you use every one. Or take BlitzAPI's Start plan: $99 for 200,000 records a month works out to $0.495 per 1,000 at its cap. On those numbers you'd pay about two and a half times as much per record on the $27 plan. The units aren't identical (MoltSets counts enrichment records, Blitz counts records returned), so read both as prices at the cap, as published: a floor, never what you'll pay per usable contact.

If you're used to credit-based pricing, the shift is that you stop paying per lookup and start paying for a speed and volume cap. And MoltSets' own billing page says it plainly: "what changes as you move up is speed and volume".

When the $27 plan appeared

The $27 plan is older than the launch. The earliest Wayback Machine capture of moltsets.com/pricing, taken 4 August 2026, already lists Free, $27, $97 and $997 a month, next to a button that says "join our closed beta". But back then you couldn't buy it without an invite.

A home page capture on 4 September says "from only $27/mo". The founder's newsletter that same day said 2,000 of 6,000 waitlisted people had been invited, and you still couldn't sign up on the site. And a support billing page dated 15 September lists paid plans at $27, $97, $397 and $997. But the 9 October launch post pushed the $27 price hard, and the 16 October issue announced a signup link on the site.

One wrinkle. The 18 September issue gives the new $397 plan 10 times "the base plan's limits". The arithmetic says that base plan is $97 (150,000 records per 5 hours against 15,000), so nothing there says the $27 plan was gone.

What I can't tell you is when the first customer paid $27. A listed price on a product you could only join by invite shows the price was set, and nothing about who paid it.

What moved at BlitzAPI

Flat monthly data plans weren't MoltSets' idea. Wayback captures of BlitzAPI's pages from 12 April and 21 July 2026 show three flat plans at $399, $499 and $599 a month, with no per-request fees. And our own snapshot on 28 September still showed them, with the $399 plan at 15,000,000 records a month (the public captures of that page give no number at all).

By 16 October the entry price had changed. A Wayback capture of Blitz's docs pricing page at 04:36 UTC that day already shows Start at $99, Scale at $499 and Build Your Infra from $999, and Blitz's docs say its launch offer "closed on October 13, 2026" (the docs don't say what the offer was, and accounts opened under it keep their price). And today, Start is $99 a month for 200,000 records at 10 requests a second per endpoint, with verified work emails and US phone numbers included. At the cap, calls pause until the next billing cycle. Scale, at $499, covers 5,000,000 records at 25 requests a second, and you'll find the full plan details on the BlitzAPI tool page.

The cuts are big, and the cap moved with them. The entry price fell 75.2%, from $399 to $99, and against the old $499 plan, the one that added emails, it fell 80.2%. But the entry allowance fell 98.7%, from 15,000,000 a month to 200,000. Cheaper, and far more capped. You need both numbers to read the change, and the cap figure rests on our 28 September snapshot alone.

Now the timing. MoltSets listed $27 on 4 August. Blitz's new entry price appeared somewhere between 28 September and 16 October, about two months later (55 to 73 days). And Blitz's September benchmark, run on 17 and 18 September, names MoltSets as one of the six vendors it tested. But Blitz hasn't said why it changed its plans. Its changelog entry of 2 September, 29 days after the $27 listing, already called plans created before 30 September "legacy plans" and said they now run at 50 requests a second. That entry is about speed and says nothing about prices, but it shows a 30 September cutoff was in view on 2 September. Causation is not shown.

What did not move

Of the vendors I could read, one cut its entry price and one raised it. But everyone else I could read held.

LeadMagic dropped its $49.99 Basic plan and now starts at $99 with Essential. But its page doesn't say why, and nothing ties that to MoltSets. FullEnrich, BetterContact and Clay show the same headline prices as their early-August captures; the copy around them changed, the numbers didn't. (If Clay's credit model is the one you're weighing, data credits versus actions covers it.)

And four well-known names I couldn't check at all. Apollo, ZoomInfo, Lusha and Prospeo don't render plan prices to a plain page fetch, so they sit in the table as unchecked. My comparison covers headline plan prices in page text only, so a vendor I didn't see move may still have moved.

Is the data any good at that price?

Cheap data only helps if the person still works there. The founder has been open about this: on 4 September he wrote that in around 20% of cases a validated, deliverable email didn't match the contact's current role, and on 18 September he put it at 15 to 20% of profiles.

We checked it ourselves. The same 821 profiles, people at ten US technology companies, went through MoltSets alone on 28 September and again on 22 October. Usable emails (the company's own domain or a known alias of it) went from 356, or 43%, to 411, or 50%. And addresses at another company's domain fell from 20% of found emails to 9%. One vendor, business email only, 24 days apart. You'll find more on the tool itself on the MoltSets page.

Blitz's own benchmark is the only cross-vendor reading I can cite. It's vendor-run, published under CC BY 4.0, and covers 3,445 LinkedIn profiles queried on 17 and 18 September. It ranked MoltSets 5 of 6: 84.6% coverage, 51.7% of answers accurate, 43.7 accurate records per 100 contacts, and a stale employer on 33.2% of returned records. And Blitz's own row came in at 82.4 accurate records per 100. But remember who ran the test: a vendor sitting inside the comparison, measuring current employer and title rather than email deliverability. And it predates the weekly refresh MoltSets announced on 16 October.

None of that tells you how either vendor does on your list. If you stack several vendors, the enrichment waterfall math can matter more than any one plan's price.

How fast it is growing

Fast, by the founder's account. His newsletter put MoltSets at $265k ARR at the end of beta week two (4 September), $360k on 18 September, and "crossed $600k ARR" on 16 October, as the waitlist cleared. These are founder-published, dated figures, and none of them is audited.

Revenue says nothing about whether other vendors' prices moved.

What would change my read

Any of these three would move me from "starting to change" to "changing", and I'll be watching for each:

1. Apollo or ZoomInfo launching an API-only tier.
2. FullEnrich or BetterContact putting out a flat monthly plan.
3. BlitzAPI saying why it repriced.

The other test is quality, and it has a date. The launch post promised a 3-day data refresh for 1 November, and a follow-up piece will rerun our 821 profiles after it to see whether usable emails keep climbing.

What to ask when someone sells you data

Put three questions to any vendor, or to whoever buys data for you:

1. Which plan is my work on, and what happens at the cap? On Blitz Start, calls pause until the next billing cycle. On MoltSets, a single call is refused with a 429 and a wait time, and a batch is cut short with the extra items dropped.
2. What does a record cost at the cap, per 1,000, in the vendor's own unit?
3. What was measured, on whose list, on what date? A vendor-run benchmark, a founder's own estimate and our 821 profiles answer three different questions.

Budgeting the whole stack? The cold outbound stack cost breakdown puts data next to everything else you pay for.

If you want these three questions put to your current data stack, that's the kind of check we run, and it's scoped per engagement.
