Five solo-run software businesses, described from their own sites: Talknotes and AudioPen turn voice notes into text, Data Fetcher pipes API data into Airtable, Attributer pushes lead attribution into CRMs, and Bank Statement Converter turns PDF bank statements into spreadsheets. Prices below are quoted from each company's own site as checked on 1 October 2026; revenue figures are founder-reported from dated interviews and are not current.

Talknotes: voice notes that come back as usable text
Talknotes (talknotes.io) records voice notes and lets AI transcribe and structure them into text such as task lists, transcripts and blog posts. It sells to anyone who talks faster than they type — people capturing ideas on the move, or turning recordings into publishable text.
The pricing page lists $19.97 per month billed monthly, or $197.00 per year (shown as about $16 a month), with a free trial.
On the company side: in an April 2024 interview the founder, Nico, reported about $5,000 a month in total revenue, said he taught himself to code and built it alone, and the interview lists 1 founder and 0 employees (Starter Story, 4 April 2024). That figure is founder-reported as of 2024; current revenue is not published in the material used here.
AudioPen: pick a style, get clean writing
AudioPen (audiopen.ai) transcribes and rewrites what you say into clear writing, in a style you choose. It is free to start, and the paid tier is AudioPen Prime: $33 for 3 months, $99 for 1 year, $159 for 2 years — which the homepage works out to $11, $8.25 and $6.63 a month.
Louis Pereira reported in a May 2024 interview that AudioPen made about $15,000 a month and that he keeps costs low because he is "a team of one" (Starter Story, 16 May 2024).
Data Fetcher: the one with a contractor bench
Data Fetcher (datafetcher.com) is a no-code Airtable extension that connects any API — or a remote CSV, JSON or XML file — to Airtable and keeps it synced on a schedule. Its customers are Airtable users who would otherwise have to write and maintain integration code.
The pricing page shows annual-billing tiers in USD: Free $0 (100 runs), Starter $15/month, Pro $30/month, Business $75/month and Business+ $112/month.
This is the one case here that is not strictly solo. In an April 2024 interview founder Andy Cloke reported $23,000 MRR "with just one full-time employee (me!) and some part-time contractors" (Starter Story, 12 April 2024). If you are asking what scaling past a pure one-person operation looks like, contractors are the step these founders describe.
Attributer: sold to marketing teams, run by one person
Attributer (attributer.io) sends marketing attribution data — which channel a lead came from — into a company's CRM and other sales and marketing tools. The buyer is a marketing or revenue team that wants channel data sitting next to the lead record.
Pricing is per site, per month (Attributer pricing): Lite $29 for up to 100 leads a month, Starter $49 for 500 leads, Professional $99 for 1,000 leads, with multi-site plans from $199 and a 14-day free trial.
In a May 2022 interview, about five months after launch, founder Aaron Beashel reported roughly $60k ARR, describing it as completely bootstrapped with himself the only person in the company (Starter Story, 10 May 2022).
Bank Statement Converter: accountants and small business owners
Bank Statement Converter (bankstatementconverter.com) converts PDF bank statements from thousands of banks worldwide into clean Excel (XLS) and CSV files. The founder-reported user base in a November 2023 interview is accountants and small business owners — a buyer who needs the file in a spreadsheet, not a nicer PDF.
The site offers limited free conversions per 24 hours and paid subscriptions, but the subscription prices are rendered by JavaScript and were not visible in the page text fetched for this article, so current prices are not stated here. The founder reported prices at the time of that interview: Starter $30 a month for 400 pages and Business $99 a month for 4,000 pages, alongside $12,500 USD monthly recurring revenue (Starter Story, 23 November 2023). Treat those as 2023 figures; they have not been re-verified against the current site.
What these five actually have in common
They are all narrow tools with a single job, priced in the tens of dollars a month or a few hundred a year, and sold to people who already have the problem — Airtable users, marketers who want channel data, accountants with PDFs, people who talk faster than they type. Four of the five were run by one person at the time of their interviews, and the fifth had added part-time contractors while remaining a one-full-time-employee company. None of that guarantees anything for a new product.
Three caveats worth reading before you use these numbers: all revenue figures are founder-reported in interviews dated between 2022 and 2024 and are not independently verified, so they say nothing about what these businesses earn now; the prices quoted are those shown on each site on 1 October 2026 and can change; and two other candidates that might have appeared here — Clicks.so and Better Sheets — could not be included because their sites failed to load, while Live Helper Chat was left out because it is open source and its pricing was not on the fetched page.
