Harvey Carpenter turned ad visitors into real inquiries with Growform

A form that turns ad visitors into real inquiries

Growform is a tool for building multi-step forms that collect consultation requests, quote requests, and applications on a website. Founder Harvey Carpenter designed the product so that ad agencies and lead-generation companies could get more valid inquiries for the same ad spend. It describes the value customers buy as "the share of ad visitors who leave an inquiry" and "customer information that can be used for sales."

Turning repeated form development into a product

Before devoting himself to Growform, Carpenter worked as a senior product manager at a London technology startup. Over several years he personally built dozens of multi-step forms and felt the need to reduce the repetitive work. He documented Growform's beginnings publicly in April 2020. The idea was to put his conversion-rate improvement experience into a reusable building tool.

In July 2020 he started a private beta. He cut a plan to prepare more than 30 industry templates down to 10 for launch, and recruited the first 5 users from acquaintances, LinkedIn contacts, and a private Facebook group. Even small feature additions and bug fixes took a lot of time, so it was a stage where he had to increase invitations carefully.

The first paying customer, secured in August 2020, was a flower wall rental company. This company, which had joined the beta, reported that inquiries increased significantly after applying the new form, and Carpenter confirmed the need to fold custom features built for customers back into the product.

Right after the first sale, he also set the direction of making agencies the main customers. He judged that agencies build forms for their clients repeatedly and understand the value of conversion-rate improvement, so he could deliver more value and charge higher prices. A record from that time mentions the expectation that he could raise prices up to five times once he found the right customers.

Connecting the input flow to ad performance measurement

Growform's basic approach is to split a long input process into several steps and change the next question based on the previous answer. It uses buttons and a progress bar, is arranged to be easy to fill in on mobile, and lets the form be adjusted to the customer company's fonts and design. Users build this flow without writing code and embed it into an existing website.

The product's reach extends past form submission. It saves UTM information that distinguishes ad traffic sources and click identifiers in hidden fields, fires conversion tracking tags, and can send the collected information to other business tools. Because agencies can see which ad produced an inquiry and reflect that result in the next campaign, the form also becomes part of measuring ad performance.

From first recurring revenue to full-time operation

Early customer acquisition started with search ads and word of mouth. The results Carpenter published in February 2021 were 15 paying customers and more than $500 in monthly recurring revenue (MRR). He also said at the time that there had been no customer churn over the previous 3 to 4 months, but that should be read together with the fact that it is an early record with still few customers.

He focused on Google ads that produced results while also testing Facebook retargeting ads of about $90 a month. The approach showed ads again to people who visited the site but did not sign up, and he assessed that the return on that investment was positive. Email outreach to prospects tried around the same time had not yet produced results.

In May 2021 he reached $1,033 in MRR. It had taken about 8 to 9 months since the first paying customer, and in the same post he announced that he would quit his job and devote himself to Growform starting June 1. It was still a point far from replacing the income from his previous job.

The transition to full time also involved a loan. A 2023 Indie Bites interview covered his resignation and a £20,000 loan as main topics. This path included not only the choice to focus his time on product development and customer acquisition but also the choice to accept a period without a salary and the burden of borrowing.

When MRR reached $2,000 in November 2021, he explained that it was close to the level that could sustain a minimal life in London. With revenue around that level, the possibility opened up of continuing to focus on the product without looking for a senior product manager job again. At the same time, he wrote that it felt strange to decline a contract offer worth $15,000 a month, which exposed the opportunity cost of continuing the independent business.

Around this time, some customers paid more than $200 a month on a separate plan not listed on the public pricing page. They were mainly marketing agencies and lead-generation companies, and they understood the value of forms with high inquiry conversion rates. It was an important change in that the early customer choice led to actual willingness to pay.

Refining search-driven traffic and usage-based pricing

In November 2022 he published $5,000 in MRR. Search traffic was about 1,000 clicks a month, which he explained was the result of accumulating practical articles about lead generation and form design. He also spent several hundred dollars on Google ads to reach people actively searching for the product.

He also recorded ineffective channels in detail. He spent $100 on Reddit ads but got no signups, and signups that could be traced to Twitter were two over a year. Sales from the affiliate program were also few, so search-driven traffic played a much more important role for Growform at the time.

In an AppSumo sale in the summer of 2022, he said he earned more than $10,000. It helped with cash flow, backlinks, and visitor growth, but there was no MRR increase that could be confirmed as coming from that sale. It is a record that evaluated the one-time sale result separately from the growth of subscription revenue.

He also revised the pricing policy. He applied collection limits to users who had been paying only $39.99 while collecting more than 1,000 leads a month and moved them to higher plans. As he also secured large contracts processing thousands of submissions a month, he strengthened the structure in which revenue grows together with usage scale.

In the Indie Bites interview published on November 22, 2023, Growform's MRR was introduced as about $7,000. The interview introduction described the customer mix as a combination of enterprise customers and other customers. This amount is the monthly recurring revenue at the time, and it should be distinguished from the net profit the founder personally takes.

Submission volume and the quality of information used for sales

The official pricing page checked in September 2026 continues the distinction by usage scale. On a monthly billing basis, Basic is $79, Professional is $139, and Scale is $249, and the monthly lead collection limits are 300, 1,000, and 3,000 respectively. The number of forms that can be activated also differs by tier, so customers running multiple campaigns are set up to choose a higher plan.

The higher plans also include real-time validation of phone numbers and email addresses and integration with consent-recording services. This reflects the requirement to secure information that sales staff can actually contact and use for follow-up work, on top of the goal of increasing submission volume. However, conversion-improvement expressions like "up to twice" on the official site are performance descriptions offered by the supplier, so they should not be read as a guarantee that applies to every customer.

What stands out about Growform is that customer choice, traffic channel, and pricing basis interlocked with each other. It chose agencies that build forms repeatedly, reached people searching for related tools, and adjusted charges according to collection volume. It shows that even a familiar feature can be grown into an independent product business when it is connected to a specific customer's repeated work and measurable business results.
