I Tested Blastra on My Former Employer’s Review-Site Presence

Blastra is a done-for-you service that gets B2B software listed, accurate and monitored across G2, Capterra and about 30 other directories that buyers and AI assistants read. I tested its free account on PartnerStack, a company whose review sites I used to manage myself. In under five minutes it produced a sharp read of how PartnerStack comes across, found a directory PartnerStack isn’t on, and connected to Claude through its MCP in a few more. It also recommended a directory that underdelivered when PartnerStack paid for it, included a UK childcare directory, and doesn’t yet rank directories by importance. My read: it’s worth it. See the done-for-you service in action with the $99 pack, then decide on ongoing support based on your time and how much consistent, well-maintained listings matter to you.

Key points:

• Free to start. Signup is two clicks with Google, and the free account includes a “Perceived Narrative Snapshot”, a 5-directory scan, the dashboard and the Blastra MCP.
• Strongest feature: the MCP. Connected to Claude, it turned a 5-directory scan into a prioritized gap list and a fit-rated list of free directories, three of them worth pursuing for PartnerStack.
• Biggest gap: it tells you what’s wrong (PartnerStack’s “fragmented” category story) but doesn’t always tell you what it recommends to change, and it doesn’t flag directories that look strong on paper but underdeliver.
• Pricing: paid plans start at $99 one-time for 3 listings, or $99 setup plus $59/month for ongoing monitoring (as of November 7, 2026).
• What I couldn’t test: the paid, done-for-you submissions. That needs a paid plan and a few weeks.

What is Blastra?

Blastra manages a software company’s listings on the directories and review sites that buyers and AI assistants read: G2, Capterra, Gartner Peer Insights, TrustRadius, SourceForge, Trustpilot and others. It scans where you’re listed, flags what’s missing or out of date, and its team submits and updates the listings for you. Its tagline is “One place to manage every listing AI and software buyers see.”

The directory list in my account covered 33 directories and launch platforms, from G2 and Capterra to niche sites for cybersecurity and web hosting. Blastra’s own pricing page promises a “full presence scan across 20+ directories” with every purchase.

It’s a mix of software and service. You onboard yourself and track progress in a dashboard, and Blastra’s team handles the submissions. For the full feature list, pricing and a summary of its G2 reviews, see our Blastra product listing.

How I tested Blastra

I signed up for a free account on November 7, 2026. I started with b2bsaasreviews.com, but once I saw what Blastra does, I realized a review site isn’t the right test. Blastra is built for software products.

So I signed up a second time with PartnerStack, my former employer. I managed PartnerStack‘s review sites myself, including its G2 profile, so I know the product and its listings well. That made it a good test: I could check Blastra’s read against what I know from the inside.

I didn’t buy a plan. Everything below comes from the free account and the Blastra MCP connected to Claude.

What is signup and onboarding like?

Sign-up takes two clicks. Blastra offers single sign-on with Google, and the first screen asks a few questions about your company, your website and your business model (B2C, B2B, B2E or B2G). From there, Blastra took less than five minutes to analyze PartnerStack‘s presence across five directories, including the reviews PartnerStack users left there.

The output is a Perceived Narrative Snapshot: how your company comes across to AI, based on your reviews, plus a “What to Do” section on what Blastra can handle. Mine is public: PartnerStack’s Perceived Narrative Snapshot.

Two more things stood out during onboarding:

• The chat reaches the founder. The free account’s support chat gives you access to Katya Rozenoer, Blastra’s founder.
• The way out of the pricing pop-up is easy to miss. After the snapshot, Blastra shows a pricing pop-up. If you don’t pick a plan, there’s no clear way to keep exploring, and no clear way to log out and try a different brand. After some clicking around, I found a small “I’ll explore on my own” link at the bottom of the pop-up. It takes you past the snapshot to the dashboard. If you’re evaluating Blastra, look for that link.

What does Blastra’s Perceived Narrative Snapshot get right?

For a five-minute, automated read, it got a lot right.

• It understood PartnerStack‘s two-sided market. It picked up both audiences: the partners in PartnerStack‘s network (PartnerStack advertises 135,000+ active partners) and the several hundred partner teams at B2B SaaS companies that run their programs on it.
• It pulled reviews from across the web to show how PartnerStack is described, not just where it’s listed.
• It mapped PartnerStack‘s key categories on each directory and found a directory it isn’t on (Crozdesk).
• It shortlisted the right kind of directories. Past the snapshot, the scan covered 5 of the 33 directories on Blastra’s list. Based on what I know about B2B SaaS review sites, it earns high marks for picking a relevant shortlist.

The pitch makes sense to me. In my experience across several early-stage SaaS companies, Series B and earlier, there’s often no customer marketer or anyone else managing review sites on an ongoing basis. Filling directory gaps, refreshing listing content and sharpening category placement fall to the back burner, and often don’t get done for long stretches. A low-cost way to close those gaps in one pass solves a real problem.

Where does the snapshot fall short?

It’s very good, but it isn’t finished. These are the gaps I found on PartnerStack.

It doesn’t rank directories by importance

The snapshot lists recommended platforms, but not in order of importance. That’s what a marketer needs to decide where to spend time. For PartnerStack, my order would be:

1. G2, because it’s where most reviews for companies in this category live (and more importantly, where rank highly in Google and LLM buyer searches.
2. Gartner Peer Insights, because many enterprise buyers go there for reviews, and it’s rising in importance for B2B SaaS companies because Gartner’s leading domain authority helps it win more and more in Google and LLM search results.
3. Capterra, GetApp and Software Advice together, because all three rank highly in Google search (and share one set of reviews).

It names the problem but not the fix

The snapshot says PartnerStack‘s category story is fragmented, and that the inconsistency gives AI tools licence to place it loosely or lump it in with pure affiliate networks, which undersells the platform. That’s accurate. But it stops there.

What would it recommend? Leaving G2’s affiliate marketing category, for example? That’s a real positioning trade-off. PartnerStack doesn’t want to be pigeonholed as an affiliate point solution, but it also can’t afford to disappear for B2B SaaS buyers looking for affiliate management software, a market where it’s arguably the number one option. I’d like to see Blastra take a position on questions like that.

It can’t tell a busy directory from a useful one

Blastra’s first recommended action for PartnerStack was to grow review volume on SourceForge. At PartnerStack, we ran a paid pilot with SourceForge. The traffic was poor, the leads fell well short of SourceForge’s own estimate, and they weren’t in our ICP.

To be fair, if the goal is more AI trust signals, more reviews on a high-authority site like SourceForge could still help. But a tool that sorts directories should also warn you when one looks meaningful on paper and underdelivers in practice.

Some directories don’t belong, and some are missing

The scan list included “Open a Nursery UK”, a directory of suppliers to UK childcare nurseries. That’s irrelevant to a partnerships platform.

It also doesn’t track app marketplaces with reviews, such as the HubSpot App Marketplace, where PartnerStack has a certified app. For PartnerStack, that’s a real miss. Many of its customers need their partner management system to sync with their CRM, and HubSpot is a popular one in that customer base.

A partial scan can look like a gap

The free account doesn’t run the full scan, so directories outside the first five can show up as “not listed” even when you are listed. Blastra showed PartnerStack as missing from Gartner Peer Insights and TrustRadius. It’s listed on both. Treat “not listed” on a partial scan as “not checked”.

What is the Blastra star, and can you trust it?

Blastra’s Monitor includes the Blastra star, a diagram of your presence across the directories it scanned. Each ray is one directory where you’re listed. A ray grows longer as that listing gathers reviews, and its colour shows the rating: pale with no rating yet, deepening to warm gold as the rating climbs, and dimming when it drops.

PartnerStack’s star had four rays: Blastra scanned five directories and found PartnerStack on four of them (all but Crozdesk). One ray was extra long and gold: G2, with 955 reviews and a 4.7 rating. Another was short and dark grey: Trustpilot, with 62 reviews and a 1.7 rating. (Both figures are from Blastra’s November 7, 2026 scan.)

It’s a handy visual for colleagues who don’t live in review sites. Read its header numbers with care, though. The star summed PartnerStack up as 4 listings, 1,111 reviews and a 3.9/5 average rating. That average treats Trustpilot’s 62 reviews the same as G2’s 955. Weighted by review count, it’s about 4.5.

The snapshot gives the context the star lacks. Its headline called out “a loud off-audience signal” and traced the Trustpilot complaints to the affiliate side, which it said “don’t reflect how B2B buyers use the product.” Here’s the story behind that signal.

Why PartnerStack‘s Trustpilot rating is 1.7

PartnerStack’s Trustpilot rating is low because it was “review-bombed”. One of the B2B SaaS companies running a partner program on PartnerStack had an unintended flaw in one of its offers: a $100 reward per lead. Bad-actor partners gamed it by submitting fake leads. Word spread online, and it went viral. Fake leads spiked so fast that the program had to be halted, and PartnerStack expelled the partners who’d submitted them.

In retaliation, the expelled partners formed a Facebook group, and one of them posted that they should each leave 1-star reviews of PartnerStack to get back at them. Many did. Trustpilot doesn’t require proof that a reviewer is a customer (it asks only if a business disputes a review), so the reviews went live.

Then the escalation slipped through the cracks. PartnerStack miscommunicated about who was taking the issue to Trustpilot. By the time PartnerStack made its case, Trustpilot cited a time limit, something like a statute of limitations, and refused to remove any of the reviews. To add insult to injury, Trustpilot kept trying to sell PartnerStack its paid offerings without doing anything to restore trust in the ratings…

The rating still shows up in AI answers. Google’s AI Overview for “partnerstack reviews” puts Trustpilot’s low rating and payout complaints right next to G2’s rating.

What does the Blastra MCP add?

The Blastra MCP connects your Blastra account to Claude, so you can ask questions about your directory presence. I think it could be one of Blastra’s most powerful features, and it’s included with the free account.

Setup was easy, with clear instructions from Blastra. It took me a few minutes, and I’m still relatively new to Claude connectors. Inside Blastra, there’s a clear table of what the MCP can access and a list of prompts to try. In Claude, you add it as a custom connector (Settings, then Connectors, then Add custom connector) with the address https://mcp.blastra.io.

Know its limits. Most of its tools are read-only: it can’t start a scan, submit or claim a listing, or buy anything. Blastra also says accounts with multi-factor authentication can’t connect yet.

I tried two of Blastra’s suggested prompts and one of my own.

“Where am I missing, and what should I fix first?” I asked one of Blastra’s suggested prompts: “Which directories are we missing from, and which of those would you prioritize first?” Claude correctly noted that Blastra had checked only 5 of its directories on the free account. It then ran web searches to see which of the bigger ones already list PartnerStack, found it on TrustRadius, Gartner Peer Insights, GetApp, Software Advice and others, and gave me the real gaps in priority order. That addressed two of my complaints above: the false negatives and the missing ranking.

• Crozdesk got a second vote. Claude confirmed Blastra’s recommendation to get PartnerStack listed on Crozdesk, so two sources now agree.
• It suggested SoftwareReviews. Claude recommended SoftwareReviews, Info-Tech Research Group’s review platform (domain rating 73 in Blastra’s directory data), noting that its reports are used for enterprise shortlisting. From what I know of SoftwareReviews, it’s also helpful with government buyers, so it’s worth a look if you sell to the public sector.
• It named a risk instead of more listings. Claude said fixing the listings PartnerStack already has would do more than adding new ones. It pointed to the 1.7 Trustpilot rating, and to Blastra’s own finding that AI answers about a vendor’s billing and support mostly cite Trustpilot. That seems like sound advice to me.

“Which free directories accept B2B products and don’t list us yet?” I asked another of Blastra’s suggested prompts: “List every directory where we are absent but that accepts B2B products and is free to list on.” Claude found 8 and gave each one a domain rating and a fit rating for PartnerStack. That fit column is what keeps you from spending time on directories that don’t suit you, and I think it judged fit well. Five of the eight met the filter but were poor fits: two security-only directories, two web-hosting directories and Open a Nursery UK. In Claude’s words, they’d “most likely reject PartnerStack or send no relevant buyers.” That left three worth pursuing: Crozdesk, SoftwareReviews and Software Finder.

The answer also explained what it left off: directories where it found a PartnerStack page, launch platforms Blastra doesn’t track, and paid directories like spotsaas ($399). And it flagged two risks. Crozdesk already lists a vendor called “Partnerstack Agency” that doesn’t appear to be the same company, so the names could get mixed up on submission. And “probably missing” only means its search didn’t find a page, so check each one by hand before you submit.

I also asked about app marketplaces, the gap I flagged earlier. Nothing new came up worth pursuing: PartnerStack is already on the HubSpot App Marketplace, and the other marketplaces weren’t relevant enough to build up reviews on.

That’s the real value of the MCP: Claude can check beyond the directories Blastra has scanned and tell you which gaps are worth closing.

What would Blastra have taken off my plate at PartnerStack?

If I’d had Blastra when I was running G2 and the other review sites at PartnerStack, it would have taken some jobs off my plate, but not the hardest ones.

That first row adds up fast. PartnerStack is on at least 14 of the 30 directories Blastra covers, including G2, Capterra, GetApp, Software Advice, Gartner Peer Insights, TrustRadius, SourceForge, PeerSpot and SaaSHub. Every pricing change, new feature or rebrand means updating each of those profiles. One $299 pack has Blastra update 12 of them in a single round, instead of someone working through them site by site.

Blastra offers a free strategy call, and I’d take it. I’ve spoken with Katya, and she knows the review landscape and review management at an expert level. A 30-minute call with her is a valuable free offer.

What about Blastra writing and submitting listing copy without showing it to you first? Some teams won’t be comfortable with that. At PartnerStack, I would have been. We had a bias for action, and we could always override the copy ourselves.

How much does Blastra cost, and is it worth it?

Prices from Blastra’s pricing page, as of November 7, 2026:

The Blastra MCP is listed on every plan.

The packs and the subscriptions do different jobs. A pack is one round of work: 3 or 12 listings created or updated, once. If your product details change later, you can update the listings yourself with the logins Blastra leaves in your dashboard, or have Blastra republish them, which uses more actions (another pack). A subscription is for upkeep: after setup, Pulse submits or updates 1 listing a month and Minimum Viable Presence 3, with regular rescans. Reinstating a lost listing also needs a subscription.

Who should buy it and who should do it themselves comes down to two questions: how many review sites you’ll list on, and how much time you have to spend on them.

In general, I think it’s worth it. Start by seeing the done-for-you submissions in action with the $99 pack (3 listings plus a full presence scan). Then consider a larger package for ongoing support, depending on how much time you have and how much you value consistent, structured listings across multiple review sites, kept up to date with minimal effort.

Think about the opportunity cost: what an hour of your time is worth, and how many hours it takes to create and maintain listings across these sites. For most SaaS professionals, there’s a lot of value at these prices, and the $299 pack for 12 listings is still reasonably priced.

What I couldn’t test

To recommend Blastra more fully, I’d need to pay for a plan, list a B2B SaaS product on multiple sites through it, and manage those listings for a few weeks. Directory approvals alone take anywhere from instant to more than two weeks, depending on the site. So this review covers the free account and the MCP, not the done-for-you service itself. I’ll update it if I run that test.

Blastra FAQ

Is Blastra legit? Yes. It’s a real company with a working product, and its free account produced an accurate read of PartnerStack‘s review-site presence in under five minutes. Its G2 reviews are positive but few (12 reviews at 4.8 out of 5 as of November 7, 2026), so weigh them accordingly (see our listing).

Does Blastra have a free trial? Its pricing page doesn’t advertise one, but you can sign up for free. The free account includes the Perceived Narrative Snapshot, a 5-directory scan, the dashboard and the Blastra MCP. The paid listing work starts at $99.

How much does Blastra cost? Paid plans start at $99 one-time for 3 listings. Ongoing plans are $99 setup plus $59/month, or $299 setup plus $99/month, and Enterprise is custom (as of November 2026).

Does Blastra work with Claude? Yes. The Blastra MCP connects your account to Claude, so you can ask about your directory gaps, priorities and free listing options. Setup took me a few minutes.

Is Blastra better than doing it yourself? It depends on how many sites you’ll list on and how much time you have. The $99 pack is an inexpensive way to see the done-for-you service in action before you commit to ongoing support.

Blastra won’t get you reviews. That’s still your job. But it shows you where you’re invisible, and the MCP turns that into a ranked to-do list. So: when did someone at your company last check every directory your buyers, and their AI assistants, read about you?
