What AI employees actually cost vs. human employees
A $100,000 salary is not the cost of a hire. The real number is closer to $180,000 once you add benefits, payroll tax, management overhead, and the equity you gave away on day one.
The loaded cost of a human hire
Founders budget for the salary line and get surprised by everything below it. Here is what a mid-level hire at a Series A startup actually costs in a typical year:
- Base salary: $95,000 (marketing manager, U.S. national median)
- Employer payroll taxes (FICA, FUTA, SUTA): ~$8,500
- Health, dental, vision insurance: ~$7,200 (employer share)
- 401(k) match at 4%: $3,800
- Equity (0.1–0.3% at Series A, valued at grant): $10,000–$30,000
- Recruiting fee (20% of first-year salary if agency): $19,000 one-time
- Onboarding + ramp time (3–4 months at reduced output): $24,000 in opportunity cost
- Manager time (5 hrs/week × $150/hr loaded cost): $39,000/year
Total first-year cost: ~$206,000. Year two drops closer to $155,000 once the recruiting fee and ramp cost disappear. But you have also given away equity that does not come back if the hire does not work out.
The cost of an AI employee
Summon charges $500/month flat. That is $6,000/year. It covers all 8 departments simultaneously — Marketing, Sales, Engineering, Finance, Design, Support, Operations, and a COO/Chief of Staff.
There is no payroll tax on it. No equity. No recruiting fee. No 90-day ramp. No severance. No manager overhead beyond the 20–30 minutes a week you spend reviewing completed tasks on the board.
If you need to stop, you cancel. No notice period. No legal review. No negotiation.
Where the comparison actually breaks down
The honest version of this analysis requires acknowledging what AI employees cannot do.
A human marketing hire brings relationships — with journalists, with design vendors, with an existing audience they can move. They can walk into a room and pitch. They can read a customer's emotional state on a call and adjust. They bring context that accumulates across years, not tasks.
An AI marketing employee can draft blog posts, run SEO audits, research competitors, write email sequences, and produce social copy. It cannot attend a conference. It cannot pick up a phone. It does not have a reputation.
The right framing is not "replace a human" — it is "what was I going to do myself, because I couldn't justify the hire?" That is where the value compounds. The tasks that fell off the bottom of your list because hiring felt too expensive are now completable at $6,000/year.
The break-even math
If a single AI department produces one outcome a month that you would otherwise have paid a contractor for, the math is straightforward:
- One SEO-optimized blog post from a freelancer: $300–$600
- One competitive research report: $500–$1,500
- One cold outreach sequence: $400–$800
- One financial model update: $500–$2,000
Any single one of those, delivered once a month, covers the $500 subscription. You have seven other departments running in parallel.
The real question
The cost comparison is less interesting than the capacity question. A solo founder with eight AI departments can have eight work streams moving at once. A founder with one human hire has one work stream moving, at $155,000/year, with all the legal and management risk that comes with it.
That is not a knock on human employees — it is an argument for sequencing. Use AI employees to do the work that does not require a human. Use the cash you save to fund the hires that do.

Does the $500/month include all 8 AI departments?
Yes. Summon's $500/month flat rate gives you access to all 8 AI departments: Marketing, Sales, Engineering, Finance, Design, Support, Operations, and COO/Chief of Staff. There is no per-seat or per-department add-on.
Are there tasks AI employees genuinely can't do?
Yes. AI employees can't build relationships, negotiate on the phone, represent you at a conference, or make a judgment call that requires deep institutional context about your specific customers. Anything requiring real-world presence, emotional trust, or a one-time contextual read is still human work.
What's the real risk of hiring a human vs. an AI employee?
A human hire carries severance risk, a notice period, a potential lawsuit if the termination is challenged, and an average 6–9 months before you know if the hire was right. An AI employee can be paused or redirected instantly, with no legal exposure and no sunk cost beyond the current month.
