Prompt Advisers Hits 7 Figures as Prompt Engineering Booms on Fiverr

Prompt Advisers crossed $1 million in revenue last year and is on track for $1.5 million to $2 million this year, according to founder Mark Kashef, who started the AI automation agency days after ChatGPT launched in late 2022.

The business now splits 70% consulting and education, 30% custom development — a reversal from 2023 and 2024, when custom work made up 70% to 80% of revenue. "Custom development in AI is kind of like death by a thousand cuts," Kashef said in an as-told-to account. "The technology moves so fast, and the scope changes very fast."

The market backdrop is shifting just as fast. Demand for Claude Code specialists has surged 938% on Fiverr over the past six months, according to the 2026 edition of Fiverr's Business Trends Index, as businesses seek freelancers who can automate workflows, build AI agents and ship products faster.

How did a $10-per-prompt gig become a 7-figure agency?

Kashef earned a master's in management and AI in 2019 and learned prompt engineering before it went mainstream. "Before it was even mainstream, I had a competitive edge," he said. He founded Prompt Advisers a few days after ChatGPT launched, with the goal of teaching people how to prompt.

He was one of the first sellers on Fiverr to post: "I will write your prompts for you." Pricing started low. "I was pricing super low because I didn't even know if there was a market for prompt engineering," he said. Rates climbed from $10 per prompt to $50, then to hundreds of dollars for a couple of pages' worth of prompts.

During the GPT-3.5 Turbo era, Prompt Advisers became the top Fiverr result for the keyword "prompt engineering," pulling roughly 50,000 impressions a month. Fiverr then reached out for PR, and the resulting press coverage put the agency on the map.

Kashef kept his full-time data science manager role while building the business, working from 4:30 a.m. to 9 a.m. and 5 p.m. to 9 p.m. daily. YouTube videos he began posting about a year and a half ago compounded the inbound demand. He left the data science role at the end of 2025.

What does the consulting business look like?

Consulting runs at 10 to 20 engagements a month. Some clients pay by the hour; others buy multi-hour packages at bulk discounts. Pricing is tiered:

• SMBs: $2,500 for a couple of hours, including a Claude Code walkthrough tailored to listed pain points, 15 minutes of one-on-one consulting per attendee and an after-session.
• Serious adopters: An $8,000-a-month retainer to track monthly changes.
• Enterprises: Packages from $15,000 to over $50,000, depending on engagement length and on-site staffing.

Enterprise clients demand tailored delivery, especially those with GDPR or SOC 2 compliance requirements. "Enterprises are more like special snowflakes," Kashef said.

Why did the business model flip?

Kashef says tools like Claude Code and CoWork have cut out much of the groundwork. Clients no longer need two weeks of explanation for a freelancer to understand their business. "I'm teaching companies how to fish, versus purely doing projects for them on an ad hoc basis," he said.

His pitch to clients is blunt about readiness: "Using AI is a luxury. It's not a right." A business earns that luxury only with clean back-end systems, orderly data and end-to-end SOPs. Prompt Advisers audits clients' interfaces and backends first; custom development requests now typically follow an initial education engagement.

Last year's first seven-figure run came with thinner margins than expected, as scope changes forced the company to hire and upskill developers. This year, Kashef projects higher profitability alongside the revenue growth. The custom development side is now limited to a small number of enterprise clients.

What is his core advice?

Kashef boils most of his guidance down to three sentences: clean your back of house, make sure your systems can talk to each other, and understand what compliance means for your business.

He also runs a community of 1,300 entrepreneurs, many of whom label themselves "non-technical" and assume they cannot use Claude Code. In practice, he says, the majority of Claude Code users in his community are non-technical people applying it to PowerPoint, Excel and Word documents rather than building software. His closing argument: "You're basically guaranteed a return on investment by just upskilling yourself," because the tools will only get easier to use and accept vaguer prompts.
