Building your AI product after you raise: a founder's guide / Plan the money
What investors expect from an AI company before the next round
Investors in the next round look at revenue, at how long customers stay, at the monthly money records, and at the code. In June 2025 Andreessen Horowitz wrote that the median enterprise AI company in its sample reached more than $2 million of annual recurring revenue in its first year and raised a Series A nine months after it started charging. This page sets out what a16z asks for in a data room and the warning signs it lists, Carta's figures for the later rounds in the first quarter of 2026, and the checks lawyers run on a company's use of open-source code.

Key takeaways
- a16z wrote in June 2025 that the median enterprise AI company in its sample passed $2 million of ARR in its first year and raised a Series A nine months after it started charging.
- a16z's data room list has five items: pitch deck, cap table, historical profit and loss with burn, usage data, and customer value against acquisition cost with payback period.
- Numbers that differ between the deck and the spreadsheets, and metrics shown only for the best groups of users, are on a16z's list of warning signs.
- Carta reports the down-round rate fell to 11.4% in Q1 2026, the lowest in nearly four years, and calls Series C the hardest stage to raise.
- Lawyers at Morgan Lewis list a written open-source policy, a scan of the code and a review of copyleft licence use among the checks before a company sale. The same records answer a technical review.
Investors in the next round look at evidence the company starts building in the first month after this one. They read the revenue, how long customers stay, the monthly money records and, for a software company, the code. This page sets out what investors at Andreessen Horowitz (a16z) have written they look for, what Carta's data says about the later rounds in 2026, and the checks lawyers list for the code in a company sale. It is part of the guide on building your AI product after you raise.
The revenue bar for AI companies has risen
In June 2025, Olivia Moore and Marc Andrusko of a16z wrote: "Pre-AI, a common benchmark for best-in-class enterprise startups was $1 million in ARR in its first 12 months" [1]. ARR, annual recurring revenue, is the revenue a company earns each year from subscriptions and other repeating contracts. An enterprise startup sells to businesses.
They then report what they see in AI companies: "The median enterprise company in our sample set reached more than $2 million in ARR in its first year, raising a Series A just nine months post-monetization" [1]. Post-monetization means after the company started charging. For companies selling to consumers, the figures were higher: "Median consumer companies performed even better, reaching $4.2 million in ARR and raising an A round within eight months" [1].
These figures describe a16z's own sample, which it calls "hundreds of companies" seen over 18 months, with no exact count [1]. They are one firm's view of the companies it saw.
| a16z figure (June 2025) | Value |
|---|---|
| Common benchmark before AI, best enterprise startups | $1 million ARR in the first 12 months |
| Median enterprise AI company in a16z's sample | More than $2 million ARR in year one |
| Time from first charge to Series A, enterprise | Nine months |
| Median consumer AI company in a16z's sample | $4.2 million ARR |
| Time to Series A, consumer | Within eight months |
What if the company has no revenue yet? The same article says investors look for evidence elsewhere: "If not yet in live commercial traction, then certainly in shipping speed and product iteration" [1]. That means how fast the company releases new versions and how much each version improves. Keep a dated record of every release and what it changed, because that record is the evidence.
Retention and churn
a16z also looks at whether customers stay. The article says: "When evaluating companies at the Series A stage, we often have no more than 12 months of usage and retention data" [1]. Retention is the share of customers or users who keep using the product over time. The same article warns that "rapid top-line growth won't be enough to compensate for low engagement or high churn" [1]. Churn is the share of customers who stop paying.
For an AI product, measure retention from the first paying customer. Show it by cohort, which is a group of users who started in the same month, so the investor can see whether each new group stays longer than the one before.
What a16z asks for in a data room
A data room is the shared folder of documents an investor reads before investing. In a 2022 guide, Justine Moore of a16z listed "the top five things we recommend including" [2]:
| Item on a16z's list | What it is | What to add for an AI product |
|---|---|---|
| 1. Pitch deck | The presentation used to raise | Claims about the AI that match what the product does |
| 2. Cap table | The list of who owns what share of the company | Every option grant and SAFE, signed |
| 3. Historical P&L and burn | Profit and loss and cash spent, month by month | Model fees and hosting shown as their own lines |
| 4. Usage data | How customers use the product | Usage by cohort, with no group left out |
| 5. LTV / CAC and payback period | What a customer is worth over time against the cost of winning them, and how many months it takes to earn that cost back | Cost to serve each customer, including model fees |
The first two columns are a16z's list. The third column is this guide's suggestion. A SAFE (simple agreement for future equity) is a contract for early investment that turns into shares later.
The same guide says a16z wants to hear "the key milestones you're looking to hit in the coming 12-18 months (and what you'll need to get there), but we don't expect a fully-baked model" [2]. A plan that names each milestone and the money it needs answers that request.
The warning signs a16z lists
The 2022 guide also lists what makes investors doubt a data room [2]:
- "Numbers that aren't consistent with what's in the deck."
- "Numbers that aren't consistent across tabs or spreadsheets."
- "Limited historical financials."
- "Selectively presented metrics."
On retention, it adds: "When you present retention or engagement data, don't cherry-pick your best cohorts of users" [2]. Show every group of users, including the weakest.
One practice addresses all four: one set of numbers, kept every month from the start and used for the deck and the spreadsheets alike, with every group of users shown. A company that builds its records this way from the first month after the raise has little to fix when the next round starts.
Investors check records, and an SEC case shows why. In June 2024 the SEC charged Ilit Raz, founder of the AI recruiting startup Joonko. The SEC alleges that "When an investor grew suspicious of Raz's claims, Raz allegedly provided the investor with falsified bank statements and forged contracts in an effort to conceal the fraud" [6]. Those are allegations in a complaint. The page describing your AI to investors and customers covers the case and others like it.
The later rounds in 2026, from Carta's data
Carta's report on the first quarter of 2026 gives the state of the rounds a seed or Series A company will face next [3]:
| Carta figure, Q1 2026 | Value |
|---|---|
| Down-round rate | 11.4%, "the lowest figure in nearly four years" |
| Series B primary pre-money valuations, year over year | Up 17.2% |
| Series C primary pre-money valuations, year over year | Up 12.5% |
| Primary rounds with a liquidation preference above 1x | 2.7% |
| Series B round counts | "stable for two years" |
| Hardest stage to raise | Series C |
A down round is a round priced lower than the one before it. A pre-money valuation is the price of the company before the new money comes in. A liquidation preference sets how much investors get back first if the company is sold, and "above 1x" means more than the amount they invested. Carta writes that "Series C remains the hardest stage to raise in the current market" [3].
David Cahn of Sequoia Capital went further in December 2025. He wrote that startups in 2025 "coined the idea of a '$0 to $100M' club of rapidly scaling AI companies; in 2026, we'll begin to talk about the '$0 to $1B' club" [4]. That is a prediction about the fastest-growing companies. A seed company should plan against the a16z and Carta figures above.
The code is checked too
Investors and buyers check the codebase, and the open-source code inside it is part of what they check. Open-source software is code published under a licence that lets others use it, with conditions. Lawyers at Morgan Lewis, writing in June 2026 about due diligence for a company sale, list these checks [5]:
- "Buyers frequently assess whether a company maintains a written OSS policy governing the use of OSS." OSS is open-source software.
- "One aspect of due diligence typically conducted requires a scan of the company's software."
- Diligence includes "a review of the company's practices relating to the use of software licensed under copyleft licenses, such as the GNU General Public License (GPL), Affero General Public License (AGPL), Lesser GPL (LGPL), and similar licenses." A copyleft licence can require a company that distributes the code to publish its own changes under the same licence.
- "Companies may maintain inventories of OSS components to assist with identifying applicable licenses, assessing compliance obligations, and understanding software dependencies."
They add that the absence of a policy could be a warning sign and, at the least, "requires further investigation and discussion with the company" [5].
Those checks were written for the sale of a company, and the same records answer a technical review in a fundraise. Write a one-page open-source policy now, keep a list of the open-source parts the product uses with their licences, and run a licence scan before the data room opens. The guide on preparing for technical due diligence and its page on the engineering data room cover the full list. For the investor's side, see AI startup due diligence.
Reveneau's view
Reveneau's view is that the evidence for the next round should be produced by the way the company works every week: one set of monthly numbers, a dated release record, retention by cohort, and code whose ownership and licences are written down. Built that way, the data room is a copy of records the company already keeps. For an AI product, add the eval suite and its dated results, which show how the product's answers scored on each test run. The page who owns code a partner or an AI writes covers the ownership records.
Reveneau is an AI software development consultancy with offices in San Francisco and Vancouver. Reveneau says AI writes all of its code and every change must pass an eval suite written from the specification, which is graded by Jev, TypeSafe AI's decision model. It says it takes responsibility for the whole project through production and after release. To plan a build around your next milestone, see AI development at Reveneau or contact Reveneau.
Common questions
What revenue do investors expect from an AI company before a Series A?
Andreessen Horowitz wrote in June 2025 that the median enterprise AI company in its sample reached more than $2 million of annual recurring revenue in its first year and raised a Series A nine months after it started charging. Before AI, a common benchmark for the best enterprise startups was $1 million in the first 12 months. The figures describe a16z's own sample.
What should be in a startup data room?
A startup data room should hold the five items Andreessen Horowitz recommended in 2022: the pitch deck, the cap table, historical profit and loss with burn, usage data, and customer lifetime value against acquisition cost with the payback period. For an AI product, show model fees and hosting as their own cost lines, and usage for every cohort of users.
Do investors expect a full financial model from a seed company?
Andreessen Horowitz wrote in its 2022 data room guide that it wants to hear the key milestones for the coming 12 to 18 months and what the company needs to reach them, and that it does not expect a fully built model. A plan that names each milestone and the money it needs answers that request, and it can be short.
What makes investors distrust a data room?
Andreessen Horowitz's 2022 guide lists four warning signs: numbers that differ from the deck, numbers that differ across tabs or spreadsheets, limited historical financials, and selectively presented metrics. One practice prevents all four: one set of numbers, kept every month and used for every document. Start keeping it in the first month after the raise.
How should a founder show retention data to investors?
A founder should show retention by cohort, a group of users who started in the same month, and include every cohort. Andreessen Horowitz's data room guide tells founders not to choose only their best groups of users. a16z also wrote in June 2025 that fast revenue growth will not make up for low engagement or high churn.
Which funding stage is hardest to raise in 2026?
Series C is the hardest stage to raise in the current market, according to Carta's report on the first quarter of 2026. The same report says Series B round counts have been stable for two years, and that Series B and Series C primary pre-money valuations rose 17.2% and 12.5% year over year. The figures cover US companies on Carta.
What is a down round and how common is it?
A down round is a funding round priced lower than the round before it. Carta reports that the down-round rate in the first quarter of 2026 fell to 11.4%, the lowest figure in nearly four years, for US companies on its platform. Carta also reports that liquidation preferences above 1x appeared in 2.7% of primary rounds that quarter.
Why do buyers ask for an open-source software policy?
Buyers ask for an open-source software policy because it shows how the company manages the licences in its code. Lawyers at Morgan Lewis wrote in June 2026 that buyers in due diligence for a merger or acquisition frequently check whether a company has a written policy, and that its absence could be a warning sign that, at the least, calls for further investigation. The same records answer a technical review in a fundraise.
What is a copyleft licence?
A copyleft licence is an open-source licence that can require a company that distributes the code to publish its own changes under the same licence. Morgan Lewis names the GNU General Public License (GPL), the Affero GPL (AGPL) and the Lesser GPL (LGPL) as examples, and says diligence reviews how a company uses software under such licences.
What does shipping speed mean to a Series A investor?
Shipping speed means how fast a company releases new versions of its product and how much each version improves it. Andreessen Horowitz wrote in June 2025 that a company without paying customers yet should show its strength in shipping speed and product iteration. A dated record of every release and what it changed is the evidence for that claim.
Why do investors check records instead of trusting the pitch deck?
Investors check records because records can be false. In June 2024 the SEC charged Ilit Raz, founder of the AI recruiting startup Joonko, and alleges that when an investor grew suspicious, Raz provided falsified bank statements and forged contracts. Those are allegations in a complaint. Records that match the deck month by month answer the investor's checks quickly.

How long a seed or Series A round lasts, and the time between rounds
A seed or Series A round has to last until the company can raise the next one. Carta's report for the first quarter of 2026 gives a median of two years from seed to Series A, 2.1 years from Series A to Series B and 2.4 years from Series B to Series C, for US companies on its platform. Runway is the number of months the money lasts at the current rate of spending. This page gives Carta's figures with their dates, shows the runway arithmetic, explains bridge rounds, and applies Paul Graham's test of whether a company reaches profit on the money it has.
Engineering budget after a raise: what one engineer costs, and the other lines
Each engineer adds a fixed cost to every month, so the engineering budget sets how long the money lasts. The US Bureau of Labor Statistics reports a median annual wage of $135,980 for software developers in May 2025. On top of the wage, an employer pays Social Security and Medicare tax, federal unemployment tax and benefits. This page works through the full cost of one engineer with the IRS rates and the BLS employer cost survey for June 2026, compares it with Y Combinator's 2016 figure, and lists the budget lines an AI product adds, such as model fees.
