Legal notice and terms

The plain version of how I work: who you’re contracting with, how work is agreed and paid for, and what I do and don’t promise.

Who I am

Forma Arc Growth Systems (“Forma Arc”) is the name I work under. I’m Mark Parfenov, a sole proprietor in the United States. Forma Arc isn’t a separate company: when you work with Forma Arc, you contract with me personally. You can reach me at mark@formaarc.io.

People I bring in

For some projects I involve senior developers or analysts from a network I’ve vetted. I only do this with your agreement, they’re bound by the same confidentiality terms, and I remain responsible to you for the work. If I introduce you to someone for work you contract directly with them, that agreement is between you and them.

Who I work with

I work with businesses, not consumers: small businesses, startups and scaleups, remotely, in English, in Europe, the UK and the US.

How work is agreed

Every project has a written scope with deliverables, milestones, acceptance criteria and a price, agreed before work starts. Changes are agreed in writing before they’re built. If a signed agreement says something different from this page, the agreement applies.

Fees and payment

The diagnostic is a fixed €950, paid before it starts. If you start implementation within 30 days of receiving the diagnostic, the full fee counts toward it. Implementation is priced per project, with payment or a deposit before the work it covers. I invoice in euros, US dollars or pounds, as agreed. Tool subscriptions and ad spend are paid by you directly and aren’t part of my fees.

Your accounts and what you own

Accounts are created in your company’s name, and you keep full access. Once paid for, the work I deliver for you is yours to use. I keep the general know-how, methods, templates and tools I bring to every project.

Confidentiality

I keep what you share about your business confidential and use it only for your project. I’m happy to sign a mutual NDA before we share sensitive details.

Personal data

When I handle personal data for you, such as leads, customers or contacts in your CRM, I do so only on your instructions and to deliver the agreed work. For clients in the EU and UK, I can sign a data processing agreement under the GDPR. How this website handles your data is on the privacy page.

No guaranteed results

I commit to the agreed scope, deliverables and care in doing the work. I don’t promise specific leads, rankings, mentions in AI tools, revenue or return on ad spend, because those depend on things outside my control, such as your market, your offer and the platforms.

Not legal, tax or financial advice

My work covers growth strategy, sales, marketing and systems. It isn’t legal, tax, accounting or investment advice; for those, please use a qualified professional.

Liability

My total liability for any project is limited to the fees you paid for that project, except where the law doesn’t allow such a limit. I’m not liable for losses caused by third-party platforms, such as ad networks, AI providers or hosting services.

Third-party platforms

Much of the work runs on platforms such as Google, Microsoft, OpenAI, Anthropic, Stripe, Vercel and Cloudflare. Their own terms and policies apply to your use of them, and they can change features or rules at any time.

Using this website

The information, guides and tools on this site are general information, provided as they are, without any warranty. They aren’t advice for your specific situation, and platform rules and features, especially for AI tools and ads, change often. I may update or remove content at any time.

Results shown on this site

Case study figures come from specific projects and were measured or estimated with the client at the time, some of them approximate. Every business is different, and past results don’t predict future ones.

Calculators and checklists

The tools on this site give estimates from the numbers you enter. They run in your browser, and nothing you enter is sent or saved.

Copyright

The text, design, guides and tools on this site are © Mark Parfenov. You’re welcome to quote short parts with a link back; please ask before republishing anything in full.

Trademarks and client names

Client, product and company names on this site, such as ChatGPT, Claude, Gemini, Google, Microsoft, Meta, LinkedIn, Stripe, Vercel and Cloudflare, belong to their owners. I mention them to describe my work and the tools I use. That doesn’t mean they endorse me or Forma Arc, and I’m not affiliated with any of these platforms unless I say so.

Links to other websites

Links to other websites are for convenience. I’m not responsible for their content, policies or availability.

Changes to this page

I may update this page from time to time. The date at the bottom shows the latest version.

If something goes wrong

Tell me first at mark@formaarc.io, and I’ll respond and try to put it right directly. The governing law and how disputes are handled are set out in each written agreement.

This page is a plain-language summary, not legal advice. The written agreement for each project is what governs it. Last updated 10 November 2026.
