Quick verdict

Both are AI-native CRMs that pull in email, calendar and meetings so sales teams type less. They differ on how they charge, which tools they connect to and how much they disclose about data handling.

Lightfield: suits teams on Salesforce or HubSpot that want to trial it alongside via two-way sync, or groups of up to 3 who want a 14-day trial of Starter ($89/user/month). From Pro up, pricing is per workspace, starting at $999/month billed annually.

Day AI: suits small teams that need only a few paid agents while colleagues use Free at no cost, and teams on Microsoft 365. The real entry price is one Professional agent at $75/month ($60/month billed annually). The pricing page lists no trial, and the founder says pricing may change.

Both are young, with no independent user ratings to cross-check. Choose by the tools your team already uses and how many people need the automated features.

Head-to-head

Lightfield leads on 2, Day AI on 3, 5 even

FeatureLightfieldDay AI
How email, calendar and meetings are captured[1],[4],[7],[8],[9]Connects email, calendar, Slack and LinkedIn, with a built-in meeting recorder. Raw emails, meetings and notes are kept as the source of truth; accounts and deals are views over them.Pulls the team's email, calendar, meetings and Slack into one shared context graph. Even the Free plan includes Gmail and Calendar ingestion and meeting recording clips.
→ Both aim to remove manual entry; neither has independent testing of how accurate the captured data is.
Outlook and Microsoft 365 support[1],[12]Its record lists email and calendar in general, without naming Outlook or Microsoft 365.Since 6 October 2026, supports Microsoft 365, covering Outlook mail, calendar and Teams, through MCP connectors.
→ Day AI explicitly confirms Outlook and Teams support; Outlook teams considering Lightfield should check with the vendor before buying.
How you work with the AI[1],[4],[8],[9]Chat is the primary interface, per the vendor's help article. Agents handle outbound, at-risk deal alerts and prioritisation; new fields can be filled from past conversations.Each agent has a name, a job and skills, reports to a team member, and runs on a new email, a recorded meeting or a schedule. Per the homepage, an audit trail records what ran and nothing goes out without approval.
→ Day AI splits work across agents whose number of automated skills depends on the plan (2, 5 or 10); Lightfield centres on chat. It is a difference in workflow, not quality.
Entry price for a small team (business plans)[2],[9]Starter: $89/user/month, billed monthly, up to 3 seats and 50,000 records. No free plan.Every workspace needs at least one Professional or Executive agent. The cheaper, Professional, is $75/month, or $60/month billed annually (set up through sales). Colleagues on Free cost nothing but get no automated skills.
→ Day AI's entry list price is lower, but the units differ: Lightfield charges per user, Day AI per agent. If everyone needs automation, count the agents before comparing.
Pricing as the team grows[2],[9]Pro is $999/month per workspace (5 capture seats, unlimited viewer seats, 250,000 records); Growth is $2,999/month (10 capture seats, 750,000 records); Enterprise is custom. All are billed annually. Extra capture seats are $200/month; unused credits do not carry over.Still per agent: Executive is $250/month ($200/month billed annually), and Super is $800/month, annual only through sales. Per-agent prices drop by up to 50% at 301+ agents.
→ Lightfield makes a large jump from Starter to Pro; Day AI grows with the number and tier of agents. Which is cheaper depends on how many people need capture or automation.
Trial and pricing certainty[2],[6],[9],[15]Starter has a 14-day trial; the pricing page states no refund policy. Per a16z, pricing follows work done and value delivered rather than static seats, so real costs may differ from the list.The pricing page lists no trial or refund policy; there is no long-term contract and you can cancel anytime in settings. The founder told Upstarts usage-based charges for power users may be needed, calling the current setup an "LLM open bar".
→ Lightfield lets you try before paying; Day AI makes cancelling easy. Neither list may reflect the full long-term cost.
Running alongside Salesforce or HubSpot[1],[4],[15]Two-way sync with Salesforce and HubSpot; an agent can ingest legacy CRM data and recreate the data model on day one; scheduled migration sessions are offered.No two-way sync with another CRM is documented. Upstarts describes one customer keeping HubSpot for about three more months while using Day AI heavily.
→ Teams not ready to drop their current CRM can trial Lightfield alongside it without keeping two systems up to date by hand.
Integrations and developer access[1],[8],[12]Gmail/email, calendar, Slack, LinkedIn, Salesforce and HubSpot; custom objects; every record readable and writable via API, MCP and CLI.Gmail, Google Calendar, Slack, Microsoft 365, Docusign, n8n and other connectors; API/SDK; since 15 September 2026 every workspace can register custom MCP connectors for internal tools.
→ Day AI lists more connectors; Lightfield documents two-way Salesforce and HubSpot sync and CLI access to records, neither of which Day AI's record mentions.
Product maturity[5],[7],[13],[14],[15]Launched publicly in November 2025 with 100+ early customers, per VentureBeat. Announced a $47M Series A led by a16z on 9 September 2026; the vendor says 5,000+ companies have signed up. No G2 or Capterra ratings found.Built from mid-2023, still in invite-only beta in June 2024, and generally available alongside a $20M Series A led by Sequoia on 2 February 2026. Upstarts reported about 120 customers. No public user ratings found.
→ 5,000+ sign-ups and about 120 customers measure different things and cannot be compared directly. Both are young with no independent validation.
Data handling and privacy[3],[10],[11]Commits not to train or fine-tune foundation AI models on customer data, or share it with third-party model providers for their training; the site footer links a SOC 2 Type II report. No retention periods and no named subprocessors.No customer data in any form used to train AI; subprocessors are published with at least 30 days' notice of new ones. Google data is deleted within 24 hours of a request or disconnection; after the subscription, data leaves active systems within 30 days and backups within 90. SOC 2 Type II report available under NDA.
→ These CRMs read email, calendar and meeting recordings; Day AI discloses more clearly how long data is kept and who processes it.

Choose Lightfield if…

  • Teams on Salesforce or HubSpot that want to trial an AI CRM alongside it via two-way sync
  • Sales groups of up to 3 who want a 14-day trial before paying (Starter)
  • Teams that need API, MCP or CLI access to every record and custom objects

Choose Day AI if…

  • Small teams that need only a few paid agents, with colleagues on Free at no cost
  • Teams on Microsoft 365 (Outlook, Teams) or that need Docusign or n8n connectors
  • Buyers who want published retention periods and a subprocessor list

How each one captures customer data

Lightfield connects email, calendar, Slack and LinkedIn and records meetings with a built-in recorder. Its help article calls this a "lossless memory": raw emails, meetings and notes are kept as the source of truth, and accounts, contacts and deals are views over them. Users define their own fields and deal stages, and new fields can be filled from past conversations.

Day AI builds a context graph from the team's email, calendar, meetings and Slack and shares it across named agents. Agents run on a new email, a recorded meeting or a schedule; per the homepage, an audit trail records what ran and nothing goes out without approval. Day AI added Microsoft 365 (Outlook, Teams) in October 2026; Lightfield's record names no email provider beyond Gmail.

What a small team pays

Every plan on both sides targets businesses. Lightfield Starter is $89/user/month, billed monthly, for up to 3 seats and 50,000 records, with a 14-day trial. Beyond 3 people the next step is Pro at $999/month per workspace (5 capture seats, unlimited viewer seats), then Growth at $2,999/month, both billed annually; extra capture seats are $200/month.

Day AI charges per agent. Every workspace needs at least one Professional or Executive agent; the cheaper, Professional, is $75/month, or $60/month billed annually. Turbo at $30/month ($24/month billed annually) can only be added alongside. Colleagues on Free cost nothing but get no automated skills. The pricing page lists no trial, and the founder told Upstarts usage-based charges may be needed. On Lightfield's side, a16z also notes real costs may differ from the list.

Integrations and leaving your current CRM

Lightfield syncs two ways with Salesforce and HubSpot, lets an agent ingest legacy CRM data and recreate the data model on day one, and offers scheduled migration sessions. Every record is readable and writable via API, MCP and CLI. Teams that want to try it without dropping their current CRM can run both in parallel.

Day AI's record lists more connectors, including Docusign, n8n and Microsoft 365, plus API/SDK and custom MCP connectors for internal tools. No two-way sync with another CRM is documented; Upstarts describes a customer keeping HubSpot for about three more months, suggesting migration tends to be gradual.

Maturity and privacy

Both are young. Lightfield launched publicly in November 2025 and announced a $47M Series A led by a16z in September 2026, with the vendor reporting 5,000+ companies signed up. Day AI has been in development since mid-2023 and became generally available in February 2026 with a $20M Series A led by Sequoia; Upstarts reported about 120 customers. Those figures measure different things. Neither has independent user ratings, and neither research record lists documented controversies or incidents. Both have English-only interfaces.

On data, both commit not to train AI on customer data and both say they have a SOC 2 Type II report. Day AI discloses more, publishing subprocessors and deletion timelines (24 hours for Google data, 30 days from active systems, 90 days from backups). Lightfield's notice gives no retention periods or named subprocessors.

Frequently asked questions

Which is cheaper for a team of 2–3?

It depends on how many people need automation. Lightfield Starter is $89 per user/month. Day AI needs at least one Professional or Executive agent (Professional is $75/month, $60/month billed annually), and colleagues on Free cost nothing but get no automated skills. The units differ, so count the seats or agents your team actually needs.

Is there a free trial?

Lightfield Starter has a 14-day trial. Day AI's pricing page lists no trial but says there is no long-term contract and you can cancel anytime in settings.

Which one can run alongside HubSpot or Salesforce?

Lightfield syncs two ways with Salesforce and HubSpot. Day AI documents no two-way sync, though Upstarts describes a customer keeping HubSpot in parallel for a while.

Which one works with Outlook?

Day AI has supported Microsoft 365, including Outlook mail, calendar and Teams, via MCP connectors since 6 October 2026. Lightfield's record does not mention Outlook, so check with the vendor first.

Do they train AI on my email?

Both say no. Lightfield says customer data is not used to train or fine-tune foundation models or shared with third-party model providers for their training; Day AI says no customer data in any form is used and its contracts bar third-party AI providers from doing so. Day AI also publishes deletion timelines and a subprocessor list.
