The takeaway

What this panel suggests

These responses show moderate interest in SoldStack’s core job: turning sold Poshmark data into clean, usable comps through an API. Buyers mainly value time savings, cleaner signals, and the ability to replace manual research or spreadsheet workflows. On price, the center of gravity sits around $20/month, with a clear preference for low-friction entry pricing. A $9/month plan is the most defensible “no-brainer” for lighter use, while $20-$29/month still feels acceptable when the service materially reduces pricing work. Around $49/month is roughly the upper edge of what this panel would entertain, though that should be treated as an individual ceiling, not a market-wide cutoff. One technically oriented respondent said their acceptable monthly price was $0 and preferred per-lookup pricing, which suggests some buyers may favor usage-based billing over subscriptions. Objections were mostly comparative: some already use tools like Keepa or Terapeak, while others can build their own scrapers. The page’s free tier and $5 pass seem well matched to the low-risk expectations expressed here.

A hypothesis to test

Pricing & positioning

Keep the entry price very low and make the value obvious fast. A $9/month starter plan looks like the clearest no-brainer for light users, while $20-$29/month appears acceptable when the API replaces manual research. Prices near $49/month look like the upper end of willingness to pay for this panel, and some technical buyers would only consider a usage-based or one-off option.

The reported median willingness to pay is $20/month, with a range from $0 to $49.One respondent would not buy a subscription at any monthly price and preferred per-lookup pricing instead.The existing $5 one-month pass and free tier are well aligned with the low-friction expectations in the responses.

SoldStack seems like a valuable tool for verifying pricing, especially since I spend so much time analyzing sold listings. For a Coach Tabby 26, I'd be looking for a median sold price around $188, so anything significantly lower would be a no-brainer to pass on. If it was priced at, say, $150, I'd stop considering it. I'd expect to get around $100-$150 for that bag, after fees. A $5 one-month pass for 1,000 lookups would be interesting to test out, but I'm not looking to commit to a monthly subscription right now.

This looks like a useful tool for verifying pricing, especially since you focus on cleaned Poshmark data. For a tool like this, I'd consider anything up to $10 per month a no-brainer, perhaps pushing to $15 if the data is exceptionally clean and covers electronics well. If it cost more than $20 a month, I'd stop considering it. I'd expect a tool like this to provide reliable, easily digestible sold prices and ideally some sell-through time data for electronics and consoles. I would not pay for this service given my current reliance on Keepa and Terapeak, which already provide extensive data for my needs. My maximum monthly spend would be $0.

This looks really promising for streamlining our manual checks. The idea of getting clean sold comps via an API is exactly what we need to speed up our buying and markdown approvals. I'd consider anything over $79 a month too expensive, given our current budget constraints and the fact that we're still a startup. A price around $29-$49 per month would feel like a no-brainer, especially if it delivers accurate, actionable data that saves us significant time. I'd expect this to effectively replace our Airtable research for at least 50% of our inventory evaluations.

This SoldStack tool seems very useful for checking pricing, especially for unique, fast-moving items like mine. The free tier with 100 lookups a month is a good start. For my business, where every rupee counts, a price around $9 USD per month for consistent use would be a no-brainer. Anything more than $29 per month would be too much to consider right now, as I need to prioritize operational costs and reinvestment. I would expect this to give me quick, reliable pricing data to help me make faster, more informed decisions on what to buy and at what price, ultimately helping me increase my profit margins and reduce risk.

This looks like a promising tool, especially the ability to clean up Poshmark data. The $5 one-month pass for 1,000 lookups seems like a good way to test its utility for our business. If it consistently provides accurate, clean data that saves me manual search time, I could see myself subscribing to the $29 tier for around $20-25 per month. It would make a no-brainer purchase if it could provide more granular data on condition variations beyond the basic categories. Anything significantly over $30 per month would make me pause.

This SoldStack service seems quite interesting. The ability to quickly access clean sold comps, especially for items like bags and jewelry, would be invaluable. For something that streamlines my current, rather manual, pricing process, I'd consider a "no-brainer" price around $29 per month. That feels like a reasonable investment for the time it could save and the accuracy it could provide, allowing me to focus more on curation and client relationships. Beyond $79 per month, I'd start to hesitate, as it would need to demonstrate significant ROI to justify the cost for my two-person boutique. I would expect to get reliable, clean data that directly informs my pricing decisions and helps me avoid underpricing or overpricing items, ultimately increasing profitability for both myself and my consignors.

The tool's concept is interesting for quickly checking sold comps, especially for items like consoles and board games that we move. The "no-brainer" price would be around $5-$10 per month for me to integrate it into my workflow for our own site and potentially for the Wallapop/eBay research. It would need to offer more than what I can quickly see on those platforms to justify a higher cost. Anything above $20 USD per month would start to feel too steep given our current margins and the free options available for basic checks, especially considering we're a 15-person company and not a massive enterprise. I'd expect to get clean, aggregated sales data with a high degree of accuracy and minimal filtering needed on my end.

Simulated interest: 40/100

Nino Dijkstrapositive

This looks like a solid tool. The ability to pull clean sold comps via API is exactly what I'm looking to automate. A 'no-brainer' price for me would be around $0.05 per lookup, maybe $0.10 tops, especially if it integrates smoothly with my Python scripts. Anything above $0.20 per lookup and I'd start questioning the ROI compared to the time it takes me to scrape it myself. I'd expect to get accurate, cleaned Poshmark sales data, ideally with median prices, days to sell, and net fees for a variety of items. I can't justify a monthly subscription given my current focus on building my own scraping tools, so my maximum acceptable price would be $0 per month.

This looks like a useful tool for getting quick sold price data, especially since it cleans up the results. For me, a 'no-brainer' price to consider paying would be around $15-$20 per month. At that point, it feels like a reasonable investment to improve accuracy without breaking the bank. If it were closer to $40 per month, I’d really need to see it significantly reduce the time I spend manually checking eBay’s sold filters, and even then, I’d be hesitant. I'd expect to get reliable, cleaned sold data that saves me at least an hour or two of manual research per week to justify the cost.

Simulated interest: 60/100

Maurice Whitepositive

This SoldStack sounds promising for checking comps, especially for the home, kitchen, and electronics I deal with. A no-brainer price for me would be if I could get at least 1,000 lookups a month for around $29. If it jumps to $79 for that many, I'd start to balk. For that price, I'd expect accurate, clean data that saves me significant time sifting through messy Poshmark sales, helping me avoid losses like that gaming console shipment. I'm willing to pay up to $29 per month for 1,000 lookups.
