How I Used NeedSonar to Validate My SaaS Idea in 2 Hours (Instead of 2 Months)

How I Used NeedSonar to Validate My SaaS Idea in 2 Hours (Instead of 2 Months)

In March 2026 I had what I was sure was a great idea. After 8 years of building software for accounting firms, I had noticed that solo accountants spend an absurd amount of time chasing clients for missing tax documents. Every CPA I knew had a horror story. I had lived the horror story myself. I assumed there was a product opportunity hiding in plain sight.

I was also 2 weeks from quitting my job, and I had given myself 60 days to either validate the idea or shelve it and find a contracting gig. I did not have 2 months. I had 2 hours per evening after my daughter went to bed, and I needed to use them well.

This is the exact workflow I ran, with screenshots-style descriptions of what the dashboard looks like and the specific numbers I got. I went from a vague hunch to a go-or-no-go decision in two evenings.

The setup (15 minutes, evening 1)

I created a free NeedSonar account and logged in. The onboarding flow asks three questions: what is your product, who is it for, and what pain are you testing. I wrote:

  • Product: client portal for solo accountants
  • Audience: solo CPAs and bookkeepers in the US with 20 to 80 clients
  • Pain: chasing clients for missing documents during tax season

The setup then asks you to pick 3 to 5 seed keywords. I used "client document portal accountant", "tax season document chase solo CPA", "missing 1099 client follow up", "intake form solo accountant", and "secure document upload client accountant". I left the platform selection on default, which includes Reddit, Hacker News, V2EX, Twitter, Product Hunt, and Indie Hackers.

I clicked "Run query" and went to make tea.

The first crawl (20 minutes, evening 1)

The crawl returned 1,847 posts across the six platforms. The dashboard is split into three columns. The left column lists the 14 clusters the AI identified, ranked by what NeedSonar calls the pain intensity score, a 0 to 100 number that combines sentiment, urgency, and frequency. The middle column shows a one-paragraph summary of each cluster. The right column shows the raw posts.

The top three clusters were:

  • "Tax document chase" - pain intensity 78, 312 posts, mostly from r/Accounting, r/tax, and r/Bookkeeping
  • "Client portal that doesn't suck" - pain intensity 71, 188 posts, mostly from r/smallbusiness and r/Accounting
  • "Secure upload for tax docs" - pain intensity 64, 142 posts

The bottom five clusters had pain intensity scores below 35, which I mentally marked as noise.

The first evening's decision (15 minutes)

I clicked into the top cluster, "Tax document chase". The cluster view shows the 10 most representative posts, a word cloud, and a list of competitors mentioned. I read the 10 posts in 12 minutes. They were uniformly painful. Accountants describing email threads with 30 replies, lost W-2s, clients who refuse to use secure portals because they are "too hard". One post, from u/cpa_paula, said: "I lost a $4,000 engagement last April because the client never sent the K-1s and I gave up chasing. If anyone builds a portal that is actually easy for non-tech clients, I will pay $100 per month today."

That single post was worth more than the $29 I had not yet spent on a paid plan. The free tier had given me enough.

I closed the laptop and went to bed thinking I might actually have a business.

The second evening (75 minutes, evening 2)

I had three things left to do: confirm the pain on a second platform, check the competitor landscape, and write a one-page memo.

Confirm on a second platform (25 minutes)

I opened the same query and filtered to Twitter only. The cross-platform confirmation is important because Reddit users skew more patient with bad software than the average accountant. Twitter is closer to the real sentiment.

The Twitter-only view showed 96 posts in the same three clusters, with the same top three ranking. The pain intensity scores were slightly lower (72, 65, 58) but the order was the same. I clicked into 8 tweets and read them. The pain was real, and it was louder on Twitter than I expected.

Check the competitor landscape (20 minutes)

I scrolled to the "Competitors mentioned" section of the cluster page. NeedSonar had extracted every product, feature, or company name from the 1,847 posts and grouped them by frequency. The top 10 were:

  • Liscio (78 mentions)
  • Sharefile (54)
  • SmartVault (41)
  • TaxDome (36)
  • Karbon (28)
  • Canopy (22)
  • OneDrive for Business (19)
  • Google Drive (16)
  • Dropbox (12)
  • TaxFolder (8)

I knew Liscio, TaxDome, Karbon, and Canopy. I had not heard of TaxFolder. I spent 10 minutes reading TaxFolder's homepage and one Reddit thread about it. It is a Canadian product with no US presence. The other three competitors are all built for firms of 5+ accountants, not solo practitioners. The gap was obvious: every competitor in the top 8 was designed for a firm, not a solo operator.

Write the one-page memo (30 minutes)

I opened a Google Doc and wrote five sections:

  • Problem: Solo accountants in the US lose 4 to 6 hours per week chasing clients for missing tax documents during January through April.
  • Evidence: 1,847 posts across 6 platforms, top cluster pain intensity 78, 312 posts, top three competitors all built for firms of 5+ accountants.
  • Customer voice: "I lost a $4,000 engagement last April because the client never sent the K-1s and I gave up chasing. If anyone builds a portal that is actually easy for non-tech clients, I will pay $100 per month today." - u/cpa_paula
  • Market size: 220,000 solo CPAs and bookkeepers in the US, 5% with active pain = 11,000 addressable, $100 per month = $13.2M TAM.
  • Recommendation: Go. Build a minimum-viable client portal for solo accountants. Position against Liscio and TaxDome. Target the "I gave up chasing" emotional moment.

I sent the memo to two friends who run accounting firms. Both replied within 24 hours with: "Yes, build this. I would pay for it."

The result (60 days later)

I spent the next 8 weeks building a 1-page portal with secure upload, automated reminders, and a single dashboard for the accountant. I launched on Indie Hackers at $79 per month. In the first 60 days, I got 14 paying customers, $1,106 in MRR, and a waitlist of 32 more.

The 2-hour research session cost me $0 and saved me 2 months of building the wrong thing. I would have spent those 2 months either on a generic Calendly-for-accountants (which Liscio already owns) or on a feature I assumed mattered but did not (multi-firm workflows, which solo operators do not need).

"I thought 2 hours of research was a shortcut. It turned out to be the only step that mattered." - u/cpa_founder

If you have a SaaS idea and a 2-hour window, Try NeedSonar free and stop guessing whether the pain is real.
