LockRoom and Firmex are the two cleanest flat rate options for boutique investment banks. Both avoid the per page billing trap that kills boutique IB economics on Datasite or Intralinks. Both meet SEC 17a-4 and FINRA 4511 record retention. Both ship reasonable audit logs.
The differences are pricing structure, ownership status (Firmex is now part of Datasite), and product investment trajectory. This page covers what each charges, where they differ, and which firm should use which.
The pricing comparison
LockRoom vs Firmex: 8 deals a year
Firmex annual unlimited tier. Sources: Vendr enterprise data, vendor websites.
LockRoom: $6,000 a year flat for unlimited rooms, unlimited users, unlimited storage. White labeling included. No setup fees. No early termination fees. No consulting add-ons. Or $375 a month for a single room with no annual commitment.
Firmex annual unlimited: ~$7,800 a year base per Vendr data. Custom branding adds $500 to $1,500. Consulting and training adds $2,000 to $5,000. 50% early termination fee on remaining contract value. Per deal pricing also available at $500 to $2,000 per month per deal.
The Datasite acquisition: what it means for Firmex customers
Datasite acquired Firmex in July 2021. Vertu Capital, Firmex's prior majority owner, exited. Firmex was set up as a "strategic business unit" within Datasite, with the management team staying in place.
Industry sources indicate Firmex has not seen major product investment since the acquisition. Caplinked's commentary (admittedly biased as a competitor) describes Firmex as being sunset in favor of Datasite's enterprise platform. Multiple analyst pieces note no significant feature releases in the 5 years since acquisition.
Practical implication: if you sign with Firmex today, you are betting that Datasite continues to invest in the Firmex product line vs migrating Firmex customers onto Datasite Diligence (per page billing) at contract renewal. That is not a guaranteed outcome.

Audit logs and compliance
Both LockRoom and Firmex meet the regulatory baseline that boutique broker-dealers need.
SEC Rule 17a-4: Both LockRoom and Firmex preserve communications and transaction records for the regulatory 6 year window. Both produce exportable audit logs in PDF and CSV format.
FINRA Rule 4511: Both meet the books and records requirements for FINRA member firms.
Audit log granularity: Firmex audit logs capture document-level activity with user attribution and timestamps. LockRoom audit logs capture page-level activity, IP addresses, search queries, and print blocked events. The LockRoom audit log is moderately more granular for reading buyer engagement during diligence.
When Firmex is the right choice
Three scenarios where Firmex makes sense:
- You already have an existing Firmex contract. Switching mid contract triggers the 50% early termination fee. Wait until renewal.
- You specifically value Firmex's M&A Fee Guide and banker interview content. Firmex publishes industry research that competing platforms do not. If that content is part of your firm's process, the platform comes with it.
- Your firm has standardized on Firmex across multiple workstreams. Sometimes the cost of switching exceeds the savings from a better platform. If everyone in your firm already knows Firmex and the workflow is locked in, the switch cost matters.
When LockRoom is the right choice
Three scenarios where LockRoom is the obvious pick:
- You're starting fresh or your Firmex renewal is up. LockRoom is $1,800 cheaper at base ($6,000 vs $7,800), with no branding fees, no early termination penalty, and no consulting add-ons.
- You want active product investment. LockRoom ships meaningful feature releases quarterly. Firmex has not had major releases since the Datasite acquisition.
- You want founder led support. LockRoom is independently operated. You reach the founder directly when issues come up. Firmex support routes through Datasite's customer success organization.
The decision framework
If you are comparing today and starting fresh, LockRoom wins on price, product investment, and lack of hidden fees. The base annual rate is ~$1,800 cheaper, branding is included, there is no early termination penalty, and active product investment continues.
If you are already on Firmex with time left on your contract, run the numbers on switching at renewal. The early termination fee usually exceeds 12 months of savings, so renewal timing is the right inflection point.
