howie raised a $6M seed round in September 2025, led by True Ventures, with participation from Jason Calacanis, Rahul Vohra, Jordi Hays, Sophia Amoruso, Turner Novak, Gaby Goldberg, Lindel Eakman, Sheel Mohnot, PJC, Roo Capital, Resolute Ventures, and several individual angels.

Before the seed, howie announced a $1M pre-seed in early 2024. The SEC Form D for the operating entity 3030 Labs shows a first sale date of June 19, 2024 and approximately $4.7M sold at that stage.

Total disclosed funding across both rounds is $7M.

howie is an AI scheduling assistant that operates through email. Instead of sending a Calendly link, a user CCs howie on an existing email thread and lets it handle the back-and-forth: proposing times, interpreting the other party's preferences, following up when someone goes quiet, placing the event on the calendar, and monitoring for conflicts afterward.

Setup is minimal. A user connects their Google Calendar and writes scheduling rules in plain language, preferred meeting lengths by type, which contacts count as VIPs, whether focus blocks can be broken for onboarding calls, and what conferencing tool to use for a pitch. howie stores those rules as a personal policy engine and applies them across threads.

The product centers on four workflows: scheduling and rescheduling meetings across multi-party threads, automatic follow-up when a counterparty goes silent, calendar auditing to catch conflicts before they become problems, and booking-link clicking on the user's behalf when the other side sends its own scheduling page.

A key product choice is to trade speed for accuracy. The system runs a waterfall of AI models that approach each scheduling task from multiple angles, and when confidence is low, a 24/7 team of former executive assistants and scheduling specialists verifies or handles the work. Tasks can take 15 minutes or longer by design. The product is optimized to avoid bad calendar decisions rather than respond instantly.

The Pro tier adds white-labeling, a custom assistant name, and an email address at the customer's own domain, so the assistant appears to external parties as a named member of the user's team rather than a third-party tool. howie currently supports Google Calendar only and does not yet support Outlook.

howie sells subscriptions directly to individual professionals and small teams through a product-led motion: when the assistant joins email threads, each scheduling interaction exposes the product to every counterparty on the thread.

Pricing is flat-rate monthly or annual rather than per-meeting, which matches the recurring nature of scheduling delegation. Basic runs $35/month (or $25/month on annual terms) and covers the core email secretary experience. Pro runs $145/month (or $95/month annually) and adds white-labeling, a custom domain email, deeper customization, and more compute per task.

The most distinctive part of the cost base is the human-in-the-loop layer. In howie's hybrid model, AI handles routine pattern-matching while former EAs handle ambiguous or high-stakes edge cases, which implies lower gross margins than a pure scheduling SaaS product. The company treats that human layer as part of the trust and service model, not a temporary workaround.

The operating thesis is that, as AI models improve and absorb a larger share of edge cases autonomously, the human layer can shift from primary delivery to exception handling and training, expanding margins over time while preserving the reliability that supports premium pricing. Each scheduling interaction also acts as a product demo for the counterparty on the thread, creating a low-CAC acquisition loop inside normal product usage.

howie competes in a category where scheduling is being folded into broader AI assistant platforms from multiple directions. The main pressure comes from incumbent scheduling platforms adding email-native AI, broader AI work assistants treating scheduling as one module among many, and native suite tools from Google and Microsoft that keep raising the free baseline.

Calendly is the most significant competitive threat. With 20M+ users and 100K+ companies already on the platform, Calendly launched Callie in May 2026, an AI scheduling assistant that users can CC in email threads to coordinate times without sending a booking link. That directly targets howie's core UX, through an installed base that is much larger than howie's current customer count.

Calendly also supports Google, Outlook, Office 365, and Exchange, so it can serve mixed-calendar enterprise environments that howie cannot reach today. The bundling risk is straightforward: as Calendly adds notetaking, reminders, and workflow automation, the AI secretary experience can become a feature inside a broader scheduling suite rather than a standalone purchase.

Lindy targets the same buyer, a busy professional looking to delegate calendar and inbox work, but with a broader product surface that includes inbox triage, meeting prep, action-item capture, CRM updates, and SMS-based coordination. It supports both Gmail and Outlook and starts at $49.99/month. Motion shows a similar pattern, expanding from AI calendar optimization into a broader work platform that includes tasks, docs, booking links, and a meeting notetaker.

That dynamic puts pressure on howie from a different angle than Calendly does. Rather than unbundling scheduling from a scheduling suite, Lindy and Motion bundle scheduling into a fuller assistant product, which raises the bar for a standalone scheduling-first tool. howie either has to expand its product surface or make the case that scheduling remains valuable enough as its own wedge.

Fyxer AI, which Sacra tracks at $30M in annualized revenue in 2025 after growing 2,900% year-over-year, provides one data point on the revenue ceiling for an email-native assistant that stays focused on a narrow workflow before expanding. Lindy and howie are both betting that the inbox and calendar become the command center for long-running tasks, the same thesis behind Tasklet, which spun out of Shortwave's inbox agent work and hit $10M ARR in May 2026.

Google's Gemini and Microsoft's Copilot in Outlook are both moving into scheduling assistance natively. Google's Help me schedule feature in Gmail suggests meeting slots from email context and calendar state. Microsoft Copilot can schedule meetings from email threads, create agendas, and reschedule conflicting events on request.

These tools face fewer trust and permission hurdles than a third-party assistant because they already sit inside the systems users rely on. howie's argument is that suite-native tools still behave more like assistive features than an autonomous secretary with programmable rules, automatic follow-up, and hybrid human QA, but that gap narrows with each platform update.

howie's current TAM is bounded by Google Calendar support and a prosumer customer base, but the product sits at a high-signal point in the scheduling workflow: the email thread where intent, urgency, and context first appear. That placement creates a path into broader coordination infrastructure.

The most direct expansion is from scheduling into the full meeting lifecycle. howie already handles pre-meeting logistics, and adjacent moves include meeting prep and attendee briefing, post-meeting follow-up, action-item capture, and CRM or task updates triggered by the meeting outcome.

That would shift howie from a scheduling tool to an execution layer for external meetings, expanding addressable spend from scheduling software budgets into GTM coordination, recruiting operations, and investor relations tooling. The same email-thread context that makes howie useful for booking meetings also contains the information needed to brief attendees, draft follow-ups, and log outcomes.

howie's current beachhead, founders, VCs, recruiters, consultants, and journalists, maps to team-level expansion in the functions where those individuals work. Recruiting teams face high-volume, rules-heavy interview scheduling with tight SLAs. Sales teams need demo booking, follow-up, and rescheduling around travel. Executive offices need calendar management that reflects organizational hierarchy and priority.

The Pro tier's white-labeling and domain-email features are already designed for this transition, letting the assistant appear as a named member of a firm rather than a third-party tool. That packaging makes howie viable for boutique professional services, wealth management, executive search, and agency environments where communication identity matters alongside scheduling accuracy.

The pricing narrative, a month of howie costs less than an hour of a human executive assistant, also opens a distinct budget category: reallocation from outsourced admin support and chief-of-staff headcount rather than displacement of a SaaS line item. That is a larger spend pool than point scheduling software.

The single largest near-term TAM expansion is Microsoft support. howie's Google-only constraint today excludes many enterprise buyers, most Microsoft-heavy organizations, and a large share of international markets where Microsoft 365 is the dominant productivity suite.

Adding Outlook would do three things simultaneously: open traditional SMB and enterprise accounts that are currently unreachable, enable legal, finance, and government-adjacent sectors with Microsoft-centric IT environments, and make international expansion viable in markets where Google Workspace has limited penetration. The demand signal is already present: Outlook support was cited as a top user request in early interviews with the founding team.

Platform dependency: howie currently operates exclusively on Google Calendar, so any change to Google's API terms, OAuth policies, or Workspace data-sharing rules could disrupt the product's core function while leaving the entire Microsoft 365 ecosystem, the dominant productivity suite in enterprise, inaccessible.

Human-layer margin drag: howie's hybrid AI-plus-human delivery model is tied to its trust proposition, but as meeting volume scales beyond 5,000+ per week, the cost of routing ambiguous cases to a 24/7 team of former executive assistants could compress gross margins faster than AI automation absorbs the workload, making the unit economics harder to sustain at scale.

Suite bundling: Google and Microsoft are both embedding scheduling assistance natively into Gmail, Calendar, and Outlook through Gemini and Copilot, respectively, raising the free baseline for scheduling help and risking a standalone AI secretary feeling redundant to users already paying for Workspace or Microsoft 365 licenses.
