Budget Season: How to Fund AI in 2027 Without Betting the Business

A CEO told us last week that his board gets the 2027 budget on December 8, and he has about 30 days to decide what AI line to put in it. He is not short of ideas. He is short of a number he can defend, because every option he has seen is either a per-seat tool nobody has a plan for, or a six-figure project with no proof behind it. His exact question was whether his company was “ready to invest at a level with consistency over time,” rather than fund one more experiment.

That question is the whole budget conversation for mid-market companies this quarter. Here is how to answer it.

The money is loosening, and the overruns are real

The appetite is back. Forrester’s 2027 planning guides report that more than 80 percent of leaders expect larger budgets over the next 12 months, with up to a quarter expecting growth of 10 percent or more. The same guides warn that where you invest matters more than how much, and that AI funded into a broken process scales the dysfunction.

The overruns are the other half of the picture. Futurum’s survey of technology buyers found that 46.9 percent of enterprises spent over their AI budget this year, and nearly half of those went back for supplemental funding. Finance teams noticed. The report expects AI budgeting to become a formal approval gate in the next planning cycle, which means the days of “we will figure out the cost later” are over.

The companies that overran did not budget too little. They budgeted for the wrong thing.

What a 2027 AI budget should actually contain

Most mid-market AI budgets fail because they contain one line: “AI.” A defensible budget has four, each with a different owner and a different confidence level.

1. Diagnosis: A fixed-price, two-week look at where your people spend energy that a system should carry, ending in a prioritized roadmap and a first win ready to build. This is the cheapest line and the one that de-risks every other line. We price a single-function version at $10,000 and a business-wide version at $25,000, because every dollar is spent deciding what to build before anything is built.
2. The first proven win, and the cadence behind it: One production system, scoped to a measurable outcome, typically starting around $25,000. A steel manufacturer we work with began with the reading of certificates that seven people handled as part of their jobs. Removing that work freed the equivalent of a full-time employee each year and paid for the next project. That is the point: wins compound, and the budget should fund the cadence that produces them. Depending on the scope of work and the size of the organization, a partnership that delivers a consistent cadence of wins runs from $12,000 to $90,000 per month. Budget it as a cadence with a 90-day gate, not as a one-off project.
3. Run costs: Hosting is modest. Model usage is the variable, and it is falling fast. In October, OpenAI shipped GPT-6.1 Terra at half the price of its predecessor and Anthropic cut Haiku pricing by roughly 90 percent. Watch the expiry dates too: Gemini 4 Argon’s launch price doubles on December 1. One distribution client runs about a thousand AI-assisted quotes a day for under $20. Budget the run, but do not inflate it. Our post on why tokens got cheaper but your bill did not explains where the real costs hide.
4. Tools and training: Per-seat licenses for the people who will use them, plus the enablement that makes the seats worth paying for. Keep this separate from the build budget so it cannot quietly absorb it.

The budgeting mistakes we see every December

The first mistake is budgeting a tool rollout as if it were a strategy. MIT’s NANDA study found that 95 percent of enterprise AI pilots deliver no measurable return, and the cause was integration and learning, not the tools. A hundred ChatGPT seats is a cost, not a plan, and without a roadmap it turns into shadow AI by March.

The second is budgeting the build and forgetting the run. Several companies in the Futurum data carried their overrun into the next year because nobody owned the usage line. Put a name on it.

The third is asking the board for a large, open-ended number. Boards fund sequences, not leaps. A diagnosis in Q1, a first win by Q2, a second by Q3, each gated by results, is a budget a CFO can approve and a board can follow. Our guide on how to pitch an AI initiative to the board walks through the framing.

The fourth is budgeting hourly. AI work carries unusual scope uncertainty, and hourly billing hands all of it to you. Fixed prices for the diagnosis and the first win keep the risk where it belongs.

How to answer the consistency question

The CEO’s real question was about commitment, not cost. Here is the honest answer we give.

Yes, AI that works takes consistent investment over time, because the gap between AI aspiration and AI that actually works is closed one workflow at a time, with the people who do the work. No, that does not mean a large upfront bet. It means a small diagnosis, a proven win, and then a partnership that scales as the wins land, with every 90 days a checkpoint where results, ROI and risk are reviewed and anything that is not working is fixed at no additional cost.

The balance the Rumble is built to strike is between the two halves of that answer. Too little investment and the wins arrive one at a time, months apart, each one re-justified from scratch. Too much and you are back to the open-ended number the board will not approve. A steady monthly commitment, sized to your scope and your organization, is what lets each win fund and de-risk the next, so the returns compound instead of resetting. For most mid-market companies that commitment lands between $12,000 and $90,000 per month, and the roadmap says which end of that range you need and why. That is how we structure every engagement, and it is why more than half of our revenue comes from clients who came back.

The December board meeting does not need to approve “AI.” It needs to approve the first two lines and the rule for unlocking the rest. Our post on measuring AI ROI before you invest gives you the numbers to attach.

If you are building the 2027 budget right now and want a number you can defend, a two-week Rumble produces the roadmap, the first win and the cost of each. Put AI to work for your people, and give the board a sequence instead of a leap.
