Technical due diligence providers, compared
Who reviews a startup codebase before a funding round, what they publish as a price, and the question that actually separates them: whether anyone reads the code or only interviews the team. Every figure read from the provider’s own page and dated.
Book a readiness auditWhat each provider charges
Ordered by published entry price. Several respected firms publish no price at all and quote after a call. That is recorded here as a fact rather than left blank, because it tells you something about how they work.

The question price doesn’t answer
Two providers at the same price can do entirely different work. Interview-led diligence talks to your founders and engineers, reviews architecture documents, and assesses team and process risk. Code-led diligence opens the repository and follows features through it. Both are legitimate. They find different problems.
Interview-led review is good at the things a codebase cannot tell you: whether the team can maintain what they built, where knowledge is concentrated in one person, whether the engineering process survives the next five hires. It will not find the authorisation check that trusts a client-supplied id.
Code-led review finds that. It is weaker on people and process, because a repository does not tell you who is about to quit. The deepest engagements do both, which is part of why an interview-heavy two-week review costs what it costs.
So ask the question directly before you compare prices: will you read the code, how much of it, and can I see a redacted sample report? The answer relocates a provider in this table far more than their headline number does.
Who is commissioning the review?
The same engagement is a different product depending on who pays for it, and that changes which provider you should be talking to.
The fund hires the reviewer
The most common arrangement. The investor picks the firm, owns the report, and you may never see the full document. Your job is to make the codebase legible: clean repo access, an architecture note, and honest answers about known debt.
You hire the reviewer first
Increasingly common, and the reason this page exists. You run your own audit before the term sheet so nothing in the investor’s report is a surprise to you. Cheaper than discovering a problem during diligence, when the leverage has already moved.
The buyer hires the reviewer
M&A and small-acquisition territory. Reports are written for a purchase decision and weight IP hygiene, contractor contribution, dependency licensing, and key-person risk far more heavily than a fundraising review does.
Where our audit fits in a fundraise — and where it doesn’t
We’re a fit if…
- You want to find what diligence will find, before the term sheet exists and while you still have leverage.
- You need the problems in plain language, with a remediation plan you can show an investor alongside the disclosure.
- Your codebase was built fast — AI tools, contractors, or an agency you have since parted ways with.
- You want the engineer who read the code on the call, not an account manager relaying findings.
Hire an independent reviewer if…
- You are the investor. Commission someone independent. Muneeb Hussain and Jezen Thomas publish fixed prices for exactly this.
- You need an interview-led assessment of team and key-person risk. madewithlove has audited 180+ startups and is built for it.
- You are buying a company rather than raising. BearingGate prices buy-side reports by deal size.
- Your investor has already named a firm. Do not litigate it; make their job easy instead.
Questions founders ask before diligence
Published prices from specialist providers currently run from about $500 at the light end to $9,500 for a deep buy-side report, with most seed-stage engagements landing between $1,250 and $5,000. Larger consultancies working on growth equity and M&A charge considerably more, often $15,000 upward, but that tier is built for a different decision than a seed round. Several well-regarded firms publish no price at all and quote after a call.
Find it before your investor does
Five business days, a 47-item report, a one-page action plan ordered by risk and effort, and a 30-minute walkthrough with the engineer who read your code. $4,999, fixed. If what you need is an independent reviewer for the fund, the table above is the better place to start.
